Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system constructed by combining an absorption or compression refrigerator with a dehumidifier using a dehumidifier.

[0002]

2. Description of the Related Art FIG. 14 shows a single-effect cycle of a conventional general absorption refrigerator Z0. The absorption refrigerator Z0 uses, for example, a lithium bromide solution as an absorption liquid and uses, for example, water as a refrigerant.
And the regenerator 52 are connected via a solution heat exchanger 55 to form an absorbent circulation system, in which the refrigerant vapor (water vapor) from the evaporator 54 is absorbed by the absorbent 51 in the absorber 51 and the refrigerant The dilute solution diluted by the absorption of the vapor is heated in the regenerator 52 to evaporate the refrigerant vapor, and the evaporated refrigerant vapor is condensed in the condenser 53 and circulated to the evaporator 54. . Attempts have been made to utilize low-temperature exhaust heat as a regenerative heat source in the regenerator 52.

On the other hand, FIG. 15 shows a cycle of a dehumidifier X0 utilizing the hygroscopicity of a dehumidifying solution (eg, lithium chloride solution). The dehumidifier X0 includes a regeneration module 6 for regenerating the dehumidified liquid by evaporating the water absorbed by the dehumidified liquid.
2, a dehumidifying module 63 for absorbing moisture in the air into the dehumidifying liquid to dehumidify the processing air,
And a solution heat exchanger 61 that exchanges heat between the regenerated dehumidifying solution from Step 2 and the moisture absorbing and dehumidifying solution from the dehumidifying module 63 to recover heat. Then, outdoor air having a high humidity is passed through the dehumidifying module 63, and the outdoor air is dehumidified in the dehumidifying module 63 to reduce its humidity, and then blown out into the room. On the other hand, low humidity indoor air is passed through the regeneration module 62 to regenerate the dehumidifying solution. In this case, the room air is heated by the heater 65 before being introduced into the regeneration module 62 to be heated to a high temperature. Air is used, and this air temperature is used as a regeneration heat source in the regeneration module 62. The water evaporated from the dehumidifying liquid in the regeneration module 62 is discharged to the outside together with the exhaust gas. By this operation, dehumidification of room air is realized.

[0004]

However, in the above-mentioned absorption refrigerator Z0, although low-temperature exhaust heat can be used as a heat source for regenerating the absorbent, the evaporation temperature of the refrigerant is, for example, 5%.
When the temperature is about 100 ° C., exhaust heat having a temperature of about 100 ° C. is required as a driving heat source. For example, when the exhaust heat is very low, such as 70 ° C. Cannot do it.

On the other hand, in the dehumidifier X using the dehumidifying liquid, although it is possible to use low-temperature exhaust heat as a regenerative heat source in the regenerating module 62, the dehumidifying liquid in the dehumidifying module 63 absorbs moisture. As a result, the coefficient of performance (hereinafter abbreviated as "COP") of the dehumidifier X0 as a whole must be low because the temperature of the processing air rises due to the heat of absorption caused by the heat.

Therefore, in the present invention, a dehumidifier using a dehumidifying liquid is combined with a refrigerator, and the generated heat of the refrigerator is used as an operating heat source of the dehumidifier, thereby realizing effective utilization of low-temperature exhaust heat and high COP. The purpose of the present invention is to provide an air conditioning system that can achieve both.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an air conditioning system according to the present invention will be specifically described based on some preferred embodiments.

First Embodiment FIG. 1 shows an air conditioning system according to a first embodiment. The air-conditioning system of this embodiment is one to which the invention described in claims 1, 2, 4, 5, 16 and 17 of the present application is applied, and includes an absorption refrigerator Z and a dehumidifier X described below. Are combined.

The absorption refrigerator Z constitutes a conventionally known single-effect cycle using, for example, lithium bromide (LiBr) as an absorbing liquid and water as a refrigerant. The solution heat exchanger 5, the low temperature regenerator 2, the condenser 3, and the evaporator 4 are connected in order. In FIG. 1, reference numeral 6 denotes a solution pump, and 7 denotes an expansion valve.

This absorption type refrigerator Z is provided with the low temperature regenerator 2
Is driven by low-temperature exhaust heat (for example, exhaust heat of 70 ° C. or less discharged from the fuel cell), and the refrigerant vapor from the evaporator 4, that is, water vapor is converted into a concentrated solution in the absorber 1. The dilute solution absorbed and diluted by the absorption of water vapor is introduced into the low-temperature regenerator 2 by the solution pump 6, where the dilute solution is heated, and the refrigerant is evaporated and concentrated to regenerate the absorbent. The concentrated solution regenerated by the low-temperature regenerator 2 is returned to the absorber 1 side. At this time, heat is recovered by heat exchange with the dilute solution in the solution heat exchanger 5. On the other hand, the refrigerant vapor generated in the low-temperature regenerator 2 is condensed in the condenser 3 and introduced into the evaporator 4 as a liquid refrigerant.
Is evaporated into refrigerant vapor, and is introduced into the absorber 1 again.

With this operation, the absorber 1 generates absorption heat (warm heat), and the evaporator 4 generates heat of evaporation (cold heat). By using as a heating heat source and a cooling heat source of X, the COP of the dehumidifier X is improved,
In the absorption chiller Z, the driving with the low-temperature exhaust heat of 70 ° C. or less as described above is realized by increasing the evaporation temperature of the refrigerant.

The dehumidifier X uses, for example, lithium chloride as a dehumidifying liquid, dehumidifies air (for example, outdoor air) by absorbing moisture of the dehumidifying liquid, and sequentially regenerates the dehumidified liquid diluted by the dehumidification. By releasing moisture, continuous dehumidification is enabled. The regeneration module 22, the dehumidification module 23, and the solution pump 24 are connected by a dehumidification liquid circulation path 29 to constitute a dehumidification liquid circulation system. In the solution heat exchanger 21, heat is recovered by heat exchange between the regenerated dehumidifying solution from the regenerating module 22 and the moisture absorbing and dehumidifying solution from the dehumidifying module 23.

In this embodiment,
The outdoor air is passed through the dehumidification module 23, the low-humidity air dehumidified here is blown out into the room, and the low-humidity indoor air is passed through the regeneration module 22 to regenerate the dehumidification liquid.

In this case, the dehumidification liquid circulation path 29 on the upstream side of the regeneration module 22 is passed through the absorber 1, and the dehumidification liquid circulation path 29 on the upstream side of the dehumidification module 23 is passed through the evaporator 4. The absorber 1 preheats the dehumidifying liquid before being introduced into the regeneration module 22 by the heat of absorption, and the evaporator 4 causes the dehumidifying liquid before being introduced into the dehumidifying module 23 by the heat of evaporation. Is previously cooled. in this way,
Heating the dehumidifying solution by the heat of absorption of the absorber 1 before the introduction into the regeneration module 22 indirectly heats the regeneration module 22 itself, and before the introduction into the dehumidification module 23. Cooling the dehumidifying liquid by the evaporation heat of the evaporator 4 indirectly cools the dehumidifying module 23 itself.

In the air-conditioning system configured as described above, the following operation and effect can be obtained.

That is, in the dehumidifying module 23 of the dehumidifier X, the moisture contained in the outdoor air passing therethrough is absorbed by the dehumidifying liquid to dehumidify the outdoor air. Since the module 23 is cooled by the heat of evaporation of the evaporator 4 of the absorption refrigerator Z, the dehumidifying action and the cooling action are simultaneously performed on the processing air (that is, outdoor air) in the dehumidifying module 23. Becomes As a result, it is possible to blow out lower-temperature air into the room as compared to a case where the air temperature tends to increase due to the heat of absorption accompanying the absorption of moisture into the dehumidifying liquid, for example, when only the dehumidifying action is performed. It is possible to improve the COP of the air conditioning system as a whole.

Further, in the evaporator 4, since it is not necessary to cool the air below the dew point, in the absorption refrigerator Z, the evaporation temperature of the refrigerant can be set high, and as a result, the absorption The type refrigerator Z can be operated with low-temperature exhaust heat of 70 ° C. or lower, and the effective use of low-temperature exhaust heat is further promoted. On the other hand, in the regenerating module 22, since the regenerative module 22 is heated by receiving the heat radiation from the absorber 1, the regenerating action of the dehumidifying liquid in the regenerating module 22 is promoted, and as a result, the COP of the air conditioning system is reduced. Further improvement can be achieved.

Further, prior to the introduction of the dehumidifying liquid into the regeneration module 22 of the dehumidifier X, the dehumidifying liquid is heated by the absorption heat generated in the absorber 1, so that the dehumidifying liquid is heated. Compared to a case where preheating is not performed, it is not necessary to incorporate a heat exchanger in the regeneration module 22, and the structure of the regeneration module 22 is simplified. Further, before the dehumidifying liquid is introduced into the dehumidifying module 23 of the dehumidifier X, the dehumidifying liquid is cooled by the heat of evaporation in the evaporator 4, so that the dehumidifying liquid is pre-cooled. Compared with the case where there is no heat exchanger, it is not necessary to incorporate a heat exchanger in the dehumidification module 23, and the simplification of the structure of the dehumidification module 23 is promoted. As a synergistic effect of these two, simplification of the structure of the dehumidifier X or downsizing is promoted.

Further, by introducing indoor air through the dehumidifying module 23, dehumidifying and cooling the air, and then introducing the air into the room, ventilation of the room is performed, and the indoor air quality is improved. Comfortable air conditioning is realized.

On the other hand, in the regenerating module 22, the room air discharged from the room is passed through the regenerating module 22, so that the regenerating action of the dehumidifying liquid is performed by the low-humidity air. Even if the temperature of the dehumidifying solution is low, it can be regenerated, and the regeneration efficiency of the dehumidifying solution in the regenerating module 22 is improved accordingly, and furthermore, the required area of the regenerating module 22 is reduced to further reduce its size. Can be promoted.

By the way, in the case where the absorber 1 and the evaporator 4 of the absorption refrigerator Z function as a heating source or a cooling source for the dehumidifier X side, as shown in FIG. First, a structure in which the dehumidifying liquid circulating in the dehumidifying liquid circulation path 29 is heated or cooled by passing the dehumidifying liquid circulation path 29 of the dehumidifier X directly through the absorber 1 or the evaporator 4 is considered. When such a direct heating / cooling structure is adopted, the regenerating module 22 and the dehumidifying module 23 have a single structure separate from the absorber 1 or the evaporator 4. FIG. 7 shows an example of the structure of the regeneration module 22 or the dehumidification module 23.

With such a configuration, in the regeneration module 22 or the dehumidification module 23, the dehumidification liquid flowing through the liquid flow path is prevented from scattering into the air, and a more comfortable air-conditioned space can be created.

On the other hand, direct heating of such a dehumidifying solution

According to such a structure, for example, the power for dispersing the dehumidifying liquid as in the case of the configuration for dispersing the dehumidifying liquid is not required, and an improvement in the COP of the air conditioning system can be expected.

According to this configuration, since the evaporator 4 and the dehumidifying module 23 can be integrally and compactly configured by the heat exchanger 46, the overall air conditioning system can be downsized. Further, the cooling of the dehumidifying liquid and the air is performed simultaneously in the heat exchanger 46, so that the thermal efficiency of the entire air conditioning system is improved.

The absorption refrigerator Z constitutes a conventionally known single-effect cycle using, for example, lithium bromide (LiBr) as an absorbing liquid and water as a refrigerant. The solution heat exchanger 5, the low temperature regenerator 2, the condenser 3, and the evaporator 4 are connected in order. In FIG. 4, reference numeral 6 denotes a solution pump, and 7 denotes an expansion valve.

The absorption type refrigerator Z is provided with the low temperature regenerator 2

The dehumidifier X uses, for example, lithium chloride as a dehumidifying liquid, dehumidifies air (for example, outdoor air) by the dehumidifying action of the dehumidifying liquid, and sequentially regenerates the dehumidified liquid diluted by the dehumidification. By releasing moisture, continuous dehumidification is enabled. The regeneration module 22, the dehumidification module 23, and the solution pump 24 are connected by a dehumidification liquid circulation path 29 to constitute a dehumidification liquid circulation system. In the solution heat exchanger 21, heat is recovered by heat exchange between the regenerated dehumidifying solution from the regenerating module 22 and the moisture absorbing and dehumidifying solution from the dehumidifying module 23.

Then, in this embodiment,

The dilute solution absorbed and diluted by the absorption of water vapor is introduced into the low-temperature regenerator 2 by the solution pump 6, where the dilute solution is heated, and the refrigerant is evaporated and concentrated to regenerate the absorbent. The concentrated solution regenerated by the low-temperature regenerator 2 is returned to the absorber 1 side. At this time, heat is recovered by heat exchange with the dilute solution in the solution heat exchanger 5. On the other hand, the refrigerant vapor generated in the low-temperature regenerator 2 is condensed in the condenser 3 and introduced into the evaporator 4 as a liquid refrigerant.

By the above operation, absorption heat (warm heat) is generated in the absorber 1 and evaporation heat (cold heat) is generated in the evaporator 4. By using as a heating heat source and a cooling heat source of X, the COP of the dehumidifier X is improved,
In the absorption chiller Z, the driving with the low-temperature exhaust heat of 70 ° C. or less as described above is realized by increasing the evaporation temperature of the refrigerant.

The dehumidifier X uses, for example, lithium chloride as a dehumidifying liquid, dehumidifies air (for example, outdoor air) by the dehumidifying action of the dehumidifying liquid, and sequentially regenerates the dehumidified liquid diluted by the dehumidification. By releasing moisture, continuous dehumidification is enabled. The regeneration module 22, the dehumidification module 23, and the solution pump 24 are connected by a dehumidification liquid circulation path 29 to constitute a dehumidification liquid circulation system. In the solution heat exchanger 21, heat is recovered by heat exchange between the regenerated dehumidifying solution from the regenerating module 22 and the moisture absorbing and dehumidifying solution from the dehumidifying module 23.

Further, in this embodiment, by applying the invention of claim 7, each of the regeneration module 22 and the dehumidification module 23 of the dehumidifier X is installed in each of the modules 22, 23. The flow direction of the dehumidifying liquid and the air is set such that the dehumidifying liquid circulating through the module and the air flow flowing through each of the modules 22 and 23 are countercurrent.

In this case, the dehumidifying liquid circulation path 29 upstream of the regeneration module 22 is passed through the absorber 1 and the dehumidification liquid circulation path 29 upstream of the dehumidifying module 23 is passed through the evaporator 4. The absorber 1 preheats the dehumidifying liquid before being introduced into the regeneration module 22 by the heat of absorption, and the evaporator 4 causes the dehumidifying liquid before being introduced into the dehumidifying module 23 by the heat of evaporation. Is previously cooled. in this way,

That is, in the dehumidifying module 23 of the dehumidifier X, the moisture contained in the outdoor air passing therethrough is absorbed by the dehumidifying liquid to dehumidify the outdoor air. Since the module 23 is cooled by the heat of evaporation of the evaporator 4 of the absorption refrigerator Z, the dehumidifying action and the cooling action are simultaneously performed on the processing air (that is, outdoor air) in the dehumidifying module 23. Becomes As a result, it is possible to blow out lower-temperature air into the room as compared to a case where the air temperature tends to increase due to the heat of absorption accompanying the absorption of moisture into the dehumidifying liquid, for example, when only the dehumidifying action is performed. It is possible to improve the COP of the air conditioning system as a whole.

Further, in the evaporator 4, it is not necessary to cool the air from the dehumidifying module 23 side to the dew point or lower, and in the absorption chiller Z, the evaporation temperature of the refrigerant can be set high. As a result, the absorption chiller Z can be operated with low-temperature exhaust heat of 70 ° C. or lower, and the effective use of low-temperature exhaust heat is further promoted.

Compared to the case where preheating is not performed, it is not necessary to incorporate a heat exchanger in the regeneration module 22, and the structure of the regeneration module 22 is simplified. Prior to the introduction of the dehumidifying solution into the dehumidifying module 23 of the dehumidifier X, the dehumidifying solution is
Since the cooling is performed by the heat of evaporation in the evaporator 4, it is not necessary to incorporate a heat exchanger in the dehumidifying module 23 as compared with a case where the pre-cooling of the dehumidifying liquid is not performed. The simplification of the structure of the module 23 is promoted. As a synergistic effect of these two, simplification of the structure of the dehumidifier X or downsizing is promoted.

As a result, the regeneration efficiency of the dehumidifying liquid in the regeneration module 22 is improved, and the required area of the regeneration module 22 can be reduced to further promote the compactness.

Further, the dehumidified liquid flowing out of the dehumidifying module 23 is returned to the evaporator 4 of the absorption type refrigerator Z to re-cool the dehumidified liquid.
Since the dehumidifying liquid flowing out of the regeneration module 22 is returned to the absorber 1 of the absorption refrigerator Z and the dehumidifying liquid is reheated, the dehumidifying liquid return path 32 is provided.
On the dehumidification module 23 side, the circulation amount of the dehumidification liquid between the evaporator 4 and the dehumidification module 23 is increased by the amount of the dehumidification liquid refluxed through the dehumidification liquid return path 31, whereby the dehumidification liquid and Since the temperature difference from the air increases and the dehumidifying efficiency increases, the size of the dehumidifying module 23 can be reduced. Also, the reproduction module 2
On the second side, the absorber 1 and the regeneration module 2 correspond to the amount of the dehumidified liquid refluxed through the dehumidified liquid reflux path 32.
Since the amount of circulation of the dehumidifying liquid between the dehumidifying liquid and the air increases, the temperature difference between the dehumidifying liquid and air increases, and the dehumidifying efficiency increases, so that the size of the regeneration module 22 can be reduced. .

Further, each of the regeneration module 22 and the dehumidification module 23 of the dehumidifier X is connected to a dehumidifying solution circulating in each of the modules 22 and 23 and an air flow flowing through each of the modules 22 and 23. Since the flow directions of the dehumidifying liquid and the air are set so as to be in the counterflow, the dehumidifying liquid and the air have a completely counterflow in each of the modules 22, 23, and the respective modules 22, 23
The temperature efficiency in the regeneration and dehumidification of the dehumidified liquid in the above is further enhanced, and the COP of the air conditioning system as a whole is further improved.
