2. Description of the Related Art Conventionally, there has been known a hot gas engine such as a Stirling cycle engine or an absorption refrigerating engine which performs cooling and heating by using a high-temperature heat source by combustion or the power of an electric motor as a driving source. A feature of this type of heat gas engine is that heat pump work is performed using a gas such as helium, nitrogen, or ammonia without using chlorofluorocarbon as a refrigerant. This type of hot gas engine has a drawback in that it is not possible to convey cold and hot heat to the indoor unit by using a refrigerant, unlike a reverse Rankine type cooling and heating machine that uses Freon.

Therefore, conventionally, a heat source for absorbing heat of a hot gas engine, a heat source for radiating heat of a hot gas engine, an indoor heat exchanger, and an outdoor heat exchanger are connected by a pipe line, and heat is transferred by cold / hot water. An air conditioner has been proposed (eg, Patent No. 185).
7581).

In this air conditioner, terminal equipment such as an indoor unit and an outdoor unit are used for both cooling and heating, so a cold water circuit and a hot water circuit are switched using a four-way valve.

[0005]

However, in the above-described conventional structure, the heat pumped from the room by the indoor unit during cooling and the heat input to drive the heat cycle are released to the outside air by the outdoor unit. There is a problem that energy cannot be effectively used. Further, even when trying to effectively utilize the heat described above, water is used as the heat carrier medium in the above conventional example, and since the water is shared by cooling and heating, an antifreeze liquid is required, and as it is as hot water supply water. There is a problem that it cannot be used. Considering the operating rate of the heat pump, there is a problem that the heat cannot be effectively used unless the time when heat is generated in the hot gas engine and the time when hot water is requested.

Further, in the above-mentioned conventional structure, since the cooling and heating are of the convection type heat exchanger, during heating,
There is a problem that it is difficult to obtain comfortable heating due to the temperature distribution that the face is hot and the feet are cold.

Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional technique and to provide a heat pump type cooling and heating apparatus capable of simultaneously heating the feet with the convection type heating by utilizing a heat carrier medium. Especially.

It can be raised to about 0 ° C. Further, according to the above invention, since the heat source for radiating heat is used to heat and supply hot water, energy can be effectively used. According to the present invention, hot water can be supplied not only during cooling but also during heating.

According to the invention of claim 5, since the hot water supply circuit switching means is provided, when there is no request for cooling or heating, and there is only a request for hot water supply, the external supply is provided without operating the hot gas engine. Water or circulating water can be heated to supply hot water. It is also possible to deal with the case where there is no request for hot water supply.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One mode of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows the configuration of a heat pump type cooling and heating apparatus according to the present invention as an actual condition. In this circuit, a hot gas engine 1 utilizing a heat pump of a Stirling cycle engine is used as a heat source. . The Stirling cycle hot gas engine 1 itself is known,
Although a detailed description is omitted, a high temperature side piston 3 and a low temperature side piston 5 are provided. The pistons 3 and 5 can operate with a 90 ° phase shift from each other, for example, when the high temperature side piston 3 reaches an intermediate position toward the top dead center, the low temperature side piston 5 reaches the top dead center. Are connected via a crank 7 driven by a motor 6.

When the high temperature side piston 3 and the low temperature side piston 5 operate, the enclosed helium moves through the regenerator 9 and, when passing through the regenerator 9, is heated or cooled, and Due to the volume change due to the movement of the piston,
Helium is boosted or depressurized. When the pressure of helium increases, the temperature rises and heat is released to the medium temperature heat exchanger 11, and when the pressure decreases, the temperature decreases and heat is absorbed from the low temperature heat exchanger 13.

That is, the low temperature heat exchanger 13 is the hot gas engine 1
, And the medium temperature heat exchanger 11 constitutes a heat radiation heat source of the hot gas engine 1.

Will be provided. The air conditioner 101 includes an indoor unit 200 and an outdoor unit 300 including the hot gas engine 1.

The indoor unit 200 includes an indoor heat exchanger 201 and an indoor fan 203. In addition, the outdoor unit 300

It has 0 and.

According to this embodiment of the present invention, the hot water supply heat exchanger 60 is connected to the hot water supply pipe (hot water supply circuit) 50 in addition to the external water supply pipe 70, and the hot water supply pipe 50 has a heat exchange for heating. Auxiliary heating means 9 including a burner 91 and a combustor 92
0 and an on-off valve 51 are provided. And this on-off valve 5
When 1 is opened, the external supply water supplied through the external water supply pipe 70 is supplied with the hot water heat exchanger 60, and further the heating heat exchanger 9
1, and after being heated there, hot water is supplied through the hot water supply pipe 50.

Further, according to this actual form, the bypass pipes 103 and 105 are connected in parallel to the heat carrier circuit connected to the heat dissipation heat source 11 via the points A and B, and the bypass pipes 103 and 105 are connected. A floor heater of the floor heater 107 is connected to the. Reference numerals 109 and 110 are both flow control valves.

Referring to FIG. 1, cold water during cooling operation,
The heat transfer circuits 40 to 47 will be described with reference to the flow of hot water.

During the cooling operation, the four-way valves 30 and 31 are shown in FIG.
At, it is switched as shown by the dotted line. in this case,
Cold water absorbed by the low temperature heat exchanger (heat source for heat absorption) 13 is
It reaches the four-way valve 30 through the pipe 40, flows to the indoor heat exchanger 201 through the control valve 110 and the pipe 41, performs heat exchange there, and rotates the indoor fan 203 to send out cool air to the room (cooling). ) After that, the pipe line 42, the four-way valve 3
1. Return to the low temperature heat exchanger (heat absorption heat source) 13 through the cold water pump 21 and the pipe 43.

At this time, the medium temperature heat exchanger (heat radiation heat source) 1
The hot water radiated in 1 is supplied to the pipeline 44, the hot water pump 20,
After flowing through the three-way valve (heat transfer circuit switching means) 400, the four-way valve 30, and the pipe 45 to the outdoor heat exchanger 301, the outdoor fan 303 is rotated there to perform heat exchange, and then the pipe 46 and four-way. Valve 31, heat exchanger 60 for hot water supply,
It returns to the intermediate temperature heat exchanger (heat dissipation heat source) 11 through the pipe line 47. By circulating cold and hot water in this way, the heat exchanger 6 for hot water supply
0 and the outdoor heat exchanger 301, or either one of the heat exchangers 60 and 301 radiates the waste heat due to the heat cycle, and the indoor heat exchanger 201 absorbs heat from the indoor air to perform cooling.

In particular, during this cooling operation, cooling efficiency is improved by radiating heat in the hot water supply heat exchanger 60 rather than radiating heat only in the outdoor heat exchanger 301, and moreover, radiating heat in the hot water supply heat exchanger 60. The more the water is supplied, the more the amount of hot water is supplied. Therefore, the energy is effectively used to produce the effect of two birds with one stone. This is easily achieved by controlling the rotation speed of the outdoor fan 303, and the maximum hot water supply capacity is obtained when the fan is stopped. However, the heating temperature in the hot water supply heat exchanger 60 cannot exceed the heat radiation temperature there. The heating temperature in the heat exchanger 60 for hot water supply is at most 30 to 50 ° C.
It is a degree.

When it is desired to raise the hot water supply temperature, the combustor 92 of the auxiliary heating means 90 may be burned in this actual form. According to this, the hot water passing through the heating heat exchanger 91 of the auxiliary heating means 90 is heated by the combustor 92,
Depending on the capacity of 2, the hot water supply temperature rises to about 80 ° C.

Next, during heating operation, the four-way valves 30, 31
Are switched as shown by the solid line in FIG. In this case, the hot water radiated by the medium-temperature heat exchanger (heat radiation heat source) 11 includes the conduit 44, the hot water pump 20, the three-way valve (heat transfer circuit switching means) 400, the four-way valve 30, the control valve 110, and the conduit. After passing through 41 to the indoor heat exchanger 201, the indoor fan 203 is rotated there to perform heat exchange, and after warm air is sent out to the room (heating), the pipe 42, the four-way valve 3
1. Return to the intermediate temperature heat exchanger (heat radiation source) 11 through the hot water supply heat exchanger 60 and the pipe line 47.

At this time, the low temperature heat exchanger (heat source for absorbing heat) 1
The cold water that has absorbed heat in 3 is pipe 40, four-way valve 30, pipe 4
5 to the outdoor heat exchanger 301, where the outdoor fan 303 is rotated to perform heat exchange, and then the low temperature heat exchanger (for heat absorption) through the pipe line 46, the four-way valve 31, the chilled water pump 21, and the pipe line 43. Return to (heat source) 13. In this way, the circulation of cold and hot water absorbs heat from the outside air through the outdoor heat exchanger 301, and the hot water supply heat exchanger 60 and the indoor heat exchanger 201, or either one of the heat exchangers 60, 20.
Waste heat from the heat cycle is radiated through 1 to perform heating or hot water supply, or simultaneous operation of heating and hot water supply.

At the time of hot water supply, external water is supplied to the hot water supply heat exchanger 60 through the external water supply pipe 70, is heated by the hot water passing therethrough, and is used for hot water supply via the hot water supply pipe 50 and the on-off valve 51. However, the heating temperature in the hot water supply heat exchanger 60 cannot naturally exceed the heat radiation temperature there. The heating temperature in the hot water supply heat exchanger 60 becomes lower than that during the cooling operation.

When it is desired to raise the hot water supply temperature, in this embodiment, the combustor 92 of the auxiliary heating means 90 may be burned.

According to this, the hot water passing through the heating heat exchanger 91 of the auxiliary heating means 90 is heated by the combustor 92, and the hot water supply temperature rises although it depends on the capacity of the combustor 92. In addition,
During heating, heat dissipation from the indoor unit 200 is also added,
Since the temperature of the hot water that can be used for hot water supply drops, it is desirable to limit the capacity of the indoor unit 200 (set a heating temperature limit) or stop the heating operation of the indoor unit during hot water supply.

Further, according to this aspect of the present invention, when there is no request for cooling or heating operation but only for hot water supply operation, the three-way valve (heat transfer circuit switching means) 400 is switched.

According to this, the hot water radiated by the medium temperature heat exchanger (heat radiating heat source) 11 flows to the pipe line 44, the hot water pump 20, the three-way valve (heat transfer circuit switching means) 400, and the indoor unit 200. To the heat exchanger 60 for hot water supply through the pipe line 48, and then returns to the intermediate temperature heat exchanger (heat source for heat radiation) 11 through the pipe line 47.

The hot water heat exchanger 60 includes an external water supply pipe 70.
External water is supplied through the heat exchanger 60. The external water is heated by the hot water supply heat exchanger 60 and is used for hot water supply via the hot water supply pipe 50 and the on-off valve 51. However, the heating temperature in the hot water supply heat exchanger 60 cannot naturally exceed the heat radiation temperature there, and is about 30 ° C. to 50 ° C. Therefore, if necessary, the combustor 92 of the auxiliary heating means 90. Will be burned.

On the other hand, the cold water absorbed by the low temperature heat exchanger (heat source for heat absorption) 13 flows through the pipe 40, the four-way valve 30 and the pipe 45 to the outdoor heat exchanger 301, where the outdoor fan 3
After exchanging heat by rotating 03, pipe 4
6, the four-way valve 31, the cold water pump 21, and the pipe line 43 are returned to the low temperature heat exchanger (heat absorption heat source) 13.

According to this, heat is absorbed from the outside air through the outdoor heat exchanger 301 by the circulation of the cold and hot water, and is radiated through the heat exchanger 60 for hot water supply by the heat cycle, and this heat is used for hot water supply. .

Further, in this actual form, heating and floor heating can be performed simultaneously. When the opening degree of the control valve 109 is opened during the heating operation, hot water flows into the floor heater of the floor heater 107 from the point A through the bypass pipe 103, the hot water joins at the point B, and passes through the pipe line 47. Returning to the intermediate temperature heat exchanger (heat radiation heat source) 11. The floor heater of the floor heater 107 radiates heat to perform floor heating.

According to this, the heating and cooling is a convection method using a convection heat exchanger, but if floor heating is performed at the same time during heating, the temperature distribution of a hot face and cold feet, which has been a problem in the past, is eliminated. And you can get comfortable heating.

Further, in this actual form, the opening of the control valve 109 is narrowed when the load of floor heating is small, and the opening of the control valve 110 is narrowed when the load of indoor heating is small. It is possible to control the temperature over the entire temperature range.

In the above-mentioned actual form, all the devices other than the indoor unit 200 are housed together in the outdoor unit 300 and are compact.

FIG. 2 shows another embodiment of the present invention. According to this, the three-way valve (switching means) 500 is provided in the bypass pipe 103 branched from the point A of the pipe line 44, and the second bypass pipe 104 is connected to this three-way valve 500, and this second The heat exchanger 93 for heating the heat medium is connected to the bypass pipe 104. This heat medium heating heat exchanger 93 is disposed in the main body 900, and
The inside of the main body 900 is filled with water, antifreeze liquid, or the like.
A heat exchanger 91 for heating the hot water supply is further disposed therein, and is indirectly heated by using a combustor 92, as in the above-mentioned actual form. These constitute the auxiliary heating means 90.

Next, the operation of this actual form will be described. In the actual form of FIG. 1, the hot water flowing through the floor heater of the floor heater 107 is hot water produced by the hot gas engine 1. If a condition that cannot be handled by the temperature of the hot water produced by the hot gas engine 1 occurs, the three-way valve (switching means) 500 is switched in the actual state of FIG. Then, the hot water produced by the hot gas engine 1 flows through the three-way valve 500 and the second bypass pipe 104 to the heat medium heating heat exchanger 93, where it is indirectly heated, and then the floor heater 10.
Flush to bed heater # 7. According to this, the floor heater 10
Since the temperature of the hot water supplied to the floor heater of No. 7 rises, even if a condition that cannot be met by the temperature of the hot water produced by the hot gas engine 1 occurs, the condition can be sufficiently met. Normally, a floor heater using resin pipes is often used because it is easy to install.However, in this type of resin, the resin serves as a heat insulating material, so a floor heater made of metal can be used. By comparison, high temperature hot water is required.

According to this aspect of the present invention, however, high-temperature hot water can be obtained, so that the present invention can be sufficiently applied to a floor heater utilizing resin pipes.

Another form of the actual condition will be described. In the above-mentioned actual forms, the hot gas engine 1 must be operated when there is no request for cooling or heating operation but only for hot water supply operation. Therefore, when there is a request only for hot water supply, another actual form is provided so that the hot gas engine 1 can be sufficiently handled without operating. As shown in FIG. 1, the external water supply pipe 70 has a three-way valve (hot water supply circuit switching valve) 4
The three-way valve 10 (hot water supply circuit switching means) 41 is connected.
A pipe line 49 bypassing the hot water supply heat exchanger 60 is connected to 0, and the pipe line 49 is connected to a hot water supply pipe 50 located downstream of the heating heat exchanger 91.

According to this, since hot water can be supplied independently of the hot gas engine 1, it is possible to sufficiently satisfy the request for only hot water supply. Further, it is possible to satisfy the hot water supply request while performing the cooling or heating operation regardless of those operations.
It can also be used when there is no request for hot water supply.

The energy saving effect in the case of each of the above actual conditions is, for example, that the heat (work) input for driving the hot gas engine 1 is 1, and the coefficient of performance (COP) during cooling is 0.
If the number is 7, the heat available for hot water supply is 1.7. Therefore, when the case of cooling and the case of supplying hot water are added, the heat that can be used becomes 2.4, and very effective heat utilization can be achieved compared to the case of performing only cooling. Considering the efficiency 0.8 of the combustor in the case of the heat-driven heat pump, the heat that can be effectively used is 2.2, which is very energy-saving in this case as well.

Further, when hot water is supplied according to the above-mentioned actual conditions, the efficiency of the hot gas engine 1 can be improved as an additional effect.

That is, in the heat pump, the efficiency can be improved by decreasing the temperature ratio (Tm / Tc) of the temperature (Tm) of the heat source for releasing heat to the temperature (Tc) of the heat source for pumping heat. In the case of the actual form, the temperature of hot water that is a heat source that releases heat is cooled by water (for example, the standard temperature of tap water during cooling is about 27 ° C.), so an air heat source (for example, air during cooling) is used. Standard temperature is about 3
The temperature is lower than that of 5 ° C., and the efficiency of the hot gas engine 1 can be improved.

Each of the pumps and each of the four-way valves in the above-mentioned actual configurations is equipped with an actuator (not shown) for operating the valve or the like. In the device 101, these actuators are provided in each operation mode. In accordance with the above, a control device (not shown) such as a microcomputer is mounted as control means for controlling as described above.

Although the present invention has been described based on the actual forms of the present invention, it is obvious that the present invention is not limited to the above-mentioned actual forms.

For example, in the above-described embodiment, the Stirling cycle heat pump is used as the hot gas engine 1. However, the hot gas engine 1 has a radiant heat source capable of generating hot water and an endothermic heat capable of generating cold water. Any material may be used as long as it has a heat source, and for example, an absorption heat pump or the like may be used. Further, in the above-mentioned actual form, the four-way valve or the on-off valve is used to control the path of the cold water or the hot water, but it can be realized by a combination of the on-off valve and the three-way valve.

[0056]

However, especially during heating, hot water can also flow to the floor heater of the floor heater through the bypass pipe, so that convection occurs. It is possible to heat the feet as well as the system heating.

According to the second aspect of the present invention, since the flow rate of the hot water flowing through the floor heater of the floor heater can be adjusted, the temperature can be controlled over a wide range.

According to the third aspect of the present invention, the temperature of the hot water flowing through the floor heater of the floor heater can be raised by flowing hot water through the second bypass pipe and operating the auxiliary heating means. The range of temperature control can be expanded.
