Abstract

(57) [Summary] [Objective] In an adsorption type air conditioner, cooling and heating capacity is enhanced by effective utilization of heating means, and cost reduction is achieved by simplifying the cooling mechanism of the heat medium. When the heating means Y heats the high temperature tube section 5A to raise the temperature of the heat medium flowing therein, the air warmed by the heating means Y passes through the air circulation tube 20 and the high temperature tube section 5A. By being introduced into the upstream side and the downstream side of the above heating means Y arrangement part, in addition to the direct heating of the high temperature pipe section 5A by the heating means Y, preheating and reheating of the heat medium by the ambient air can be performed. This makes it possible to accelerate the activation of the heat exchanger 2 with an adsorbent in the discharge process without increasing the amount of heat of the heating means Y and to obtain a higher cooling / heating capacity. Further, by cooling the low temperature pipe portion 5B with the low temperature air introduced into the air circulation pipe 20, it is not necessary to install a dedicated cooling means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorption type air conditioner.

[0002]

2. Description of the Related Art Conventionally, a pair of adsorption type refrigeration units having a heat exchanger with an adsorbent, which uses an adsorbent such as zeolite or silica gel, which reversibly adsorbs and desorbs water in response to temperature changes, has been provided. There is known an adsorption type air conditioner that is installed in parallel and performs reversible operation of each of the adsorption type refrigeration units to perform heating and cooling (for example, Japanese Patent Laid-Open No. 63-4635).
(See Japanese Patent Publication No. 6).

In such an adsorption type air conditioner,
The adsorbent of the adsorption refrigeration unit in the adsorption process cools it with a heat medium to promote the adsorption of water, and the adsorbent of the adsorption refrigeration unit in the release process heats it with a heat medium to remove the moisture. By facilitating the release, and alternately performing such adsorption / release processes every predetermined time, a continuous cooling / heating operation is enabled. The cooling and heating capacity in this case increases as the amount of water adsorbed in the adsorption process increases and the amount of water released in the discharge process increases.

By the way, as a method of heating the heat medium supplied to the heat exchanger with the adsorbent of the adsorption refrigeration unit in the discharge step, the adsorption refrigeration unit in the adsorption step to the adsorption refrigeration unit in the discharge step can be used. It has been a conventional general method to dispose a heating means such as a gas burner in the middle of a heat medium pipe for feeding the heat medium to the side and directly heat the heat medium by the heating means. On the other hand, as a method of cooling the heat medium supplied to the heat exchanger with the adsorbent of the adsorption refrigeration unit in the adsorption process, the adsorption refrigeration unit in the discharge process is changed to the adsorption refrigeration unit side in the adsorption process. Generally, a dedicated cooler is arranged in the middle of a heat medium pipe for supplying the heat medium, and the heat medium is cooled by the cooler.

[0005]

However, according to such a conventional heating / cooling method for a general heating medium, there are the following problems. That is, regarding the heating side,
The heat medium pipe is directly heated by a gas burner or the like. In this case, part of the heat of the gas burner is used to heat the heat medium, while the other heat heats the ambient air. Since it is released into the air as it is, it cannot be said that it is effectively used. Therefore, the amount of heat generated by the gas burner is small, the temperature of the heating medium does not rise, and as a result, the cooling and heating capacity decreases, and if a certain cooling and heating capacity is to be ensured, a larger amount of heat is required for the gas burner. Therefore, it is not preferable in terms of downsizing or cost reduction of the device.

Further, in terms of the cooling side, there is also a problem that the apparatus becomes large and complicated because a dedicated cooling means is required.

Therefore, the present invention provides an adsorption type air conditioner in which the cooling and heating capacity is enhanced by effectively utilizing the heating means and the cost is reduced by simplifying the cooling mechanism of the heat medium. It was made as a sentence.

And an outlet (22A or 22B) located on the downstream side of the heat medium for each of the dampers 25 and 26, and an outlet (22B located on the upstream side of the heat medium.
Alternatively, it is characterized in that opening / closing control is performed so that 22A) is opened.

According to a third aspect of the present invention, as shown in FIG. 1, in the adsorption type air conditioner according to the first or second aspect, the heating means Y is a combustion heat source 1 such as a gas burner.
It is characterized by being configured by 1.

In the invention according to claim 4, as illustrated in FIG. 2, in the adsorption type air conditioner according to claim 1 or 2, the heating means Y is constituted by a non-combustion type heat source 30 such as a solar system. It is characterized by doing.

[0012]

With each of the inventions of the present application, the following effects can be obtained by adopting such a configuration.

According to the first aspect of the present invention, the heat is supplied from the heat exchanger with adsorbent 2 of the adsorption type refrigeration unit in the adsorption stroke to the heat exchanger with adsorbent 2 in the discharge stroke through the high temperature pipe portion 5A. The heating medium is heated by the heating means Y arranged on the way. Further, in this case, a part of the heat of the heating means Y is used for heating the surrounding air, but the peripheral air heated by the heating means Y passes through the air circulation pipe 20 and the heating portion of the high temperature pipe portion 5A. Of the heat medium, and further heats the heat medium in this portion. That is, the heating medium is preheated by the high temperature air on the upstream side of the heating means Y, and the heating means Y at the heating means Y portion.
Is heated directly and further reheated in a portion downstream of the heating means Y. As a result, the temperature is raised by the preheating action and the reheating action as compared with the case where the air circulation pipe 20 is not provided. The heat medium temperature rises by the amount, and the heat medium having the higher temperature is supplied to the adsorbent-equipped heat exchanger 2 on the discharge process side, so that the working medium W is released from the adsorbent-equipped heat exchanger 2. It is further promoted.

On the other hand, when the air flows from the air inlet portion 21 toward the air outlet portion 22 in the air circulation pipe 20, the low temperature pipe portion 5 located upstream of the heating means Y.
B is cooled by low-temperature air, and the heat medium is supplied to the adsorbent-equipped heat exchanger 2 on the adsorption process side in a low temperature state to promote adsorption of the working medium W in the adsorbent-equipped heat exchanger 2.

According to the second aspect of the invention, the air outlet portion 22 of the air circulation pipe 20 is composed of the first outlet 22A and the second outlet 22B located on both sides of the heating means Y, and the two outlets 22A and 22B are provided. Since the dampers 25 and 26 are provided at the outlets 22A and 22B, respectively, and the damper located on the downstream side of the heat medium is closed and the damper located on the upstream side is opened, particularly in the upstream side portion where the damper is closed, The hot air is accumulated around the hot tube portion 5A to further promote the reheating action of the heat medium, and the recooling by the air flow is prevented, and the heat medium is discharged at a higher temperature. It will be supplied to the heat exchanger 2 with the adsorbent on the side.

On the other hand, after the air is introduced from the air inlet portion 21, it passes through the inside of the air circulation pipe 20 and is discharged to the outside from the outlet on the upstream side of the heat medium in which the damper is opened. In this case, in the upstream side of the air flow of the heating means Y of the high temperature tube portion 5A, the high temperature ambient air heated by the heating means Y is slightly cooled by the air flow, but still a considerable preheating effect is obtained. It is what is done. Furthermore, since one of the two dampers 25, 26 is always open, air is always flowing in the air flow pipe 20, and therefore, the cooling action of the heat medium on the low temperature pipe section 5B side by the air flow is prevented. It will always be maintained in a proper state.

In the invention according to claim 3, the heating means Y
Is composed of a combustion type heat source such as a gas burner, when the surrounding air is heated by the combustion gas after directly heating the high temperature pipe part 5A, the combustion gas is directly mixed with the air to heat the surrounding air. The action is accelerated, and as a result, the preheating and reheating actions on the heat medium are further improved than those described above and described.

In the invention according to claim 4, the heating means Y
Is constituted by a non-combustion type heat source such as a solar system, the high temperature pipe portion 5A is directly heated by the high temperature water supplied from the heat source through the heat transfer tube to raise the heat source temperature and By guiding the warm water of which the temperature has been somewhat lowered after heating the portion 5A to the upstream side of the air flow pipe 20, where heat is exchanged with the surrounding air and flowing this toward the high temperature pipe portion 5A side, The above and described actions are achieved.

[0019]

Therefore, according to the adsorption type air conditioner of the present invention, the following effects can be obtained.

(A) According to the adsorption type air conditioner of claims 1, 3 and 4, the heat generated by the heating means Y is utilized not only for direct heating of the heating medium but also for preheating and reheating thereof. The temperature of the heat medium can be increased to supply it to the heat exchanger 2 with the adsorbent on the release stroke side, and the heat medium is cooled by the air flowing through the air flow pipe 20 to heat the heat medium with the adsorbent on the adsorption stroke side. Since it can be supplied to the exchanger 2, the amount of the working medium W released in the discharging process and the amount of the working medium W adsorbed in the adsorption process both increase, and the cooling and heating capacity is improved accordingly.

Further, since the cooling means for cooling the heat medium is constituted by the air flow pipe 20 and the air flow flowing through the air flow pipe 20, as compared with the case where a dedicated cooler is provided, for example. There is also an effect that the device can be made compact and the cost can be reduced.

(B) According to the adsorption type air conditioner of the second aspect, by enclosing the high temperature air in the air circulation pipe 20 on the downstream side of the heating medium from the heating means Y, the reheating action can be promoted. Therefore, it is possible to supply a heat medium having a temperature higher than that in the case described in (a) to the heat exchanger 2 with an adsorbent on the release stroke side, and as a result, in the case described in (a) above. It is possible to obtain even higher air conditioning capacity than

[0023]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The adsorption type air conditioner of the present invention will be specifically described below with reference to the embodiments shown in the accompanying drawings.

[0024] The first embodiment Figure 1 there is shown a system diagram of a suction type air conditioner according to an embodiment of the invention of claim 1, 2, and 3 described, reference numerals U _1, U in FIG Reference numeral ₂ is a pair of adsorption type refrigeration units having the same structure which are reversibly operated with each other.
The structure of this adsorption refrigeration unit will be described by taking the first adsorption refrigeration unit U ₁ as an example. The adsorption refrigeration unit U ₁ includes an adsorbent 3 such as zeolite and its interior in a closed container 1. A heat exchanger 2 with an adsorbent that adsorbs and releases water according to the temperature of the adsorbent 3 by using water as a working medium W, and a heat exchanger 2 with the adsorbent. As the working medium W is adsorbed and released, heat is exchanged with the working medium W, whereby the working medium W is exchanged.
And a working medium heat exchanger 6 having an action of causing evaporation or condensation.

The heat exchanger with an adsorbent 2 of the adsorption refrigeration unit U ₁ is adsorbed on the adsorbent 3 by heating the adsorbent 3 with a heat medium supplied to the heat transfer tube 4. The gas medium wb (that is, water vapor) of the working medium W is released, and conversely, the adsorbent 3 is cooled by the heat medium so that the gas medium Wb is adsorbed on the adsorbent 3. Further, the working medium heat exchanger 6 evaporates or condenses the working medium W as the working medium W is adsorbed / released by the heat exchanger 2 with an adsorbent. The heat of vaporization and the heat of condensation in this case are used as a heat source for cooling and heating.

This adsorption type air conditioner comprises the above-mentioned pair of adsorption type refrigeration units U ₁ ,
In order to reversibly operate U ₂ to enable continuous cooling and heating, the heat transfer tubes 4 and 4 of the heat exchangers 2 with adsorbents of the adsorption type refrigeration units U ₁ and U ₂ are connected to each other by a high temperature tube section. The heat transfer tubes 4 are connected to each other by a heat medium tube 5 composed of a low-temperature tube section 5B provided with a pump 13 capable of reversible operation (corresponding to a reversible circulation means in claims) in the middle thereof. , 4
Together with a series of heat medium circulation system X, an indoor heat exchanger 7 and an outdoor heat exchanger 8 are connected to the working medium heat exchangers 6, 6 to connect the indoor heat exchanger 7 and the outdoor heat exchanger 6, respectively. The heat exchanger 8 and the heat exchangers 6 for working mediums can be reversibly switched and connected.

On the other hand, each of the adsorption type refrigeration units U ₁ and U ₂ described above
In order to cause the adsorbent 3 to adsorb and release the working medium W as described above, it is necessary to heat or cool the adsorbent-equipped heat exchangers 2, 2 alternately. Therefore, in this embodiment, the high temperature pipe portion 5 of the heat medium pipe 5 is used.
A gas burner 11 (corresponding to the heating means Y in the claims) is arranged in the middle of A so that the heat medium flowing in the high temperature pipe section 5A can be directly heated by the gas burner 11 while the high temperature An air circulation pipe 20 described later is arranged between the pipe portion 5A and the low temperature pipe portion 5B.

The air flow pipe 20 is composed of a tubular body integrally formed in a substantially Y shape, and the end portion on the merging side thereof serves as an air inlet portion 21, and both branch end portions are respectively formed into a first branch. 1
The outlet 22A and the second outlet 22B are provided (the air outlet 22 is constituted by the pair of outlets 22A and 22B).
Further, dampers 25 and 26 are provided at the outlets 22A and 22B, respectively. The air flow pipe 20 is arranged such that the air inlet portion 21 side thereof is located on the low temperature pipe portion 5B side and the outlets 22A, 22B side thereof are located on the high temperature pipe portion 5A side, respectively. The high temperature pipe portion 5A and the low temperature pipe portion 5B are exposed inside, and the gas burner 11 is positioned substantially at the center of the in-pipe passage portion 24. Further, the in-pipe passage portion 2
A fan 12 is arranged at an intermediate position between the gas burner 11 and the low temperature pipe portion 5B in the No. 4 unit. Therefore, when the air flow pipe 20 is attached, the high temperature pipe portion 5A is
Will be accommodated not only in the heating portion of the gas burner 11 but also in the air flow pipe 20 over a relatively wide range on both sides thereof.

It should be noted that the pump 13 is arranged so that it can send the high-temperature heat medium after being heated by the gas burner 11 to the heat exchanger 2 with adsorbent of the adsorption type refrigeration unit on the discharge stroke side. The operating direction is controlled. For example, when the first adsorption type refrigeration unit U ₁ is in the discharge stroke, the heat medium is caused to flow in the direction indicated by the broken line arrow in FIG. 1, and conversely, when the second adsorption type refrigeration unit U ₂ is in the discharge stroke. The operation is controlled so that the heat medium flows in the direction indicated by the solid arrow.

The dampers 25 and 26 are selectively opened and closed, and the operation thereof is such that the damper 25 or 26 close to the adsorption type refrigeration unit, which is always in the discharge stroke, is closed and the damper stroke is changed. The damper 26 or 25 near the adsorption type refrigeration unit is controlled so as to open (incidentally, FIG. 1 shows the state when the second adsorption type refrigeration unit U ₂ is in the discharge stroke).

Subsequently, with respect to the operation of the adsorption type air conditioner constructed as described above, the second adsorption type refrigeration unit U ₂ is in the discharging process centering on the operation of the heat exchangers 2 and 2 with adsorbent. Taking the case as an example, in this case, the pump 1
Reference numeral 3 denotes a heating medium that is refluxed in the direction indicated by the solid arrow. In the dampers 25 and 26, the first outlet 22
The damper 25 provided at A is open, and the damper 26 provided at the second outlet 22B is closed. In this state, the gas burner 11 heats the central portion of the high temperature pipe portion 5A, and the fan 12 causes the inside of the in-pipe passage portion 24 of the air circulation pipe 20 to flow from the air inlet portion 21 to the first outlet 2
Flow air toward the 2A side.

Then, first, on the high temperature pipe section 5A side,
It is the same as that of the conventional structure that the central portion thereof is directly heated by the gas burner 11 and the temperature of the heat medium inside thereof is raised. However, the present embodiment does not stop there. Since the air around the burner 11 is warmed by the heat of the gas burner 11 and the high temperature pipe portion 5A is located over a relatively wide range in the atmosphere in which the warm air flows or stays, The heat medium is preheated by the high temperature air on the upstream side of the arrangement position of the gas burner 11 of the pipe portion 5A, and the heat medium is reheated by the high temperature air on the upstream side portion, and particularly on the downstream side. In this case, since the damper 26 is closed, in this portion, high temperature air is enclosed in the pipe passage portion 24 and is once heated. Nor as that medium is cooled by the air flow. As a synergistic effect of these, the heat medium temperature introduced into the heat exchanger 2 with an adsorbent of the second adsorption type refrigeration unit U ₂ uses the heat of the gas burner 11 only for direct heating of the heat medium as in the conventional case. However, compared with the case where the warm air around the periphery (that is, the exhaust heat of the gas burner 11) is directly emitted into the atmosphere without being used, the temperature is further enhanced. Therefore, a higher temperature heat medium is supplied to the heat exchanger 2 with adsorbent of the second adsorption type refrigeration unit U _{2 in} the discharging process, and the heat medium from the adsorbent 3 in the heat exchanger 2 with adsorbent is supplied. The release of the working medium W is further promoted.

In this case, since the gas burner 11 is used as the heating means Y, the combustion gas thereof is easily mixed with the ambient air which is also a gas. Therefore,
When the air is heated simply by using the convection action of the air, the temperature of the surrounding air rises faster and becomes higher due to the heating due to the mixing action. As a result, the second adsorption formula Heat exchanger with adsorbent ₂ of refrigeration unit U 2
The temperature of the heating medium supplied to is further increased.

On the other hand, on the low temperature pipe portion 5B side, the air flow introduced from the air inlet portion 21 into the pipe passage portion 24 flows in contact with the low temperature pipe portion 5B. 5B is air-cooled, so that the heat medium flowing therein is also cooled. Therefore, the cooled low temperature heat medium is supplied to the heat exchanger 2 with the adsorbent of the first adsorption type refrigeration unit U _{1 in} the adsorption process, and the adsorption of the working medium W to the adsorbent 3 is promoted. Becomes

As described above, in the adsorption-type air conditioner of this embodiment, the second adsorption-type refrigeration system in which the heat medium is heated to a higher temperature by making more effective use of the generated heat amount of the gas burner 11 to release it Heat exchanger with adsorbent ₂ of unit U 2
In the second adsorption type refrigeration unit U ₂ , since the heat medium temperature is high, the adsorbent 3 is supplied to the second adsorption type refrigeration unit U ₂ .
The amount of working medium discharged from the air flow pipe 2 increases.
Since the heat medium is supplied to the heat exchanger 2 with adsorbent of the first adsorption type refrigeration unit U ₁ in the adsorption stroke in a state where the heat medium is at a lower temperature by the air flow flowing in 0,
In the first adsorption type refrigeration unit U ₁ , the adsorption amount of the working medium to the adsorbent 3 increases due to the lower heat medium temperature, and as a result, the adsorption / release in each adsorption type refrigeration unit U ₁ , U ₂ . The amount of adsorption and release of the working medium W due to the action increases,
The cooling and heating capacity of the adsorption type air conditioner is enhanced to that extent.

Further, in this embodiment, since a part of the air circulation pipe 20 is made to function as the cooling means Z for cooling the heat medium, it is not necessary to provide a dedicated cooler as in the conventional case. Therefore, the device can be made compact or the cost can be reduced.

Second Embodiment FIG. 2 shows an adsorption type air conditioner according to an embodiment of the invention described in claims 1, 2 and 4 of the present application. The adsorption type air conditioner of this embodiment has the same basic configuration as that of the first embodiment described above, and differs from that of the first embodiment in that of the first embodiment. In contrast to the gas burner 11 used as the heating means Y, the hot water obtained by the solar system 30 is used as the heating means Y in this embodiment.

That is, in this embodiment, the upstream portion of the heat transfer tube 31 to which hot water from the solar system 30 is supplied is wound around the outer periphery of the high temperature tube section 5A, and
The downstream portion is arranged in the in-pipe passage portion 24, and the upstream portion is covered by the cover 32 so that the air flow does not directly impinge on it.

In such a case, the hot water sent from the solar system 30 first directly heats the high temperature pipe portion 5A in the upstream portion of the heat transfer pipe 31 so as to raise the temperature of the heat medium therein. It acts and the high temperature pipe section 5
The hot water whose temperature has dropped somewhat due to the heating of A is the heat transfer tube 3
It acts so as to heat the air flow flowing in the pipe passage portion 24 in the downstream portion of 1. Then, the air warmed in the downstream portion of the heat transfer tube 31 passes through the inside of the pipe passage portion 24 and is discharged from the first outlet 22A thereof, while the air is warmed on both sides of the heat transfer tube 31 arrangement portion of the high temperature pipe portion 5A. The heating medium in the high temperature pipe section 5A is preheated or reheated by heating over a relatively wide range. Therefore, as in the conventional case, the high temperature pipe section 5 is directly connected.
As compared with the case of only heating A, the temperature of the heat medium is further increased by the amount preheated and reheated by the ambient air,
As a result, the cooling and heating capacity of the adsorption type air conditioner will be enhanced.

When the hot water of the solar system 30 is used as a heating heat source, the heating temperature of the heating medium is relatively high as compared with the case where the gas burner 11 is used as in the first embodiment. Since the adsorbent 3 has a low temperature, it is suitable when an adsorbent having a relatively low adsorption / desorption temperature such as silica gel is used.
