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).

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 case where the outside air temperature is extremely low when the present apparatus operates as a cooling and heating apparatus, and when rapid heating is required, the conventional configuration should sufficiently meet the requirement. There is a problem that you can not.

Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional example and to provide a heat pump type cooling and heating apparatus which can sufficiently meet the demand for rapid heating.

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

FIG. 1 shows the configuration of an embodiment of a heat pump type air conditioner according to the present invention. In this circuit, a hot gas engine 1 using 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.

However, according to this embodiment, the air conditioner 101 using the low temperature heat exchanger (heat absorbing heat source) 13 and the medium temperature heat exchanger (heat radiating heat source) 11 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
Is the hot gas engine 1, the outdoor heat exchanger 301, and the outdoor fan 3.
03, further, a hot water pump 20, a cold water pump 21, a three-way valve (heat transfer circuit switching means) 400,
A three-way valve (switching means) 500, four-way valves 30, 31, a hot water supply heat exchanger 60, and an external water supply pipe 70 for guiding external supply water to the hot water supply heat exchanger 60 are provided.

Further, according to this embodiment, 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. Vessel 91, combustor 92, and heat exchanger 9 for heating hot water
An auxiliary heating means 90 composed of 3 and an opening / closing valve 51 are provided. When the on-off valve 51 is opened, the external water supply pipe 7
External water supplied through 0 is the hot water heat exchanger 6
0, and further, it is introduced into the heat exchanger 91 for heating, heated there, and then supplied with hot water through the hot water supply pipe 50. The auxiliary heating means 90 is, so to speak, an indirect heating device, and the main body 900 is filled with water, antifreeze liquid, or the like, in which the above-mentioned heating heat exchanger 91 and hot water heating heat exchanger 93 are provided. Is installed.

The heat exchanger 93 for heating the hot water is connected to the bypass pipes 53 and 55, and the bypass pipes 53 and 55 are connected.
Are connected in parallel to a heat transfer circuit 44 described later via the above-described three-way valve (switching means) 500.

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

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
After passing through the pipe line 40 to the four-way valve 30 and flowing through the pipe line 41 to the indoor heat exchanger 201, heat is exchanged there, and the indoor fan 203 is rotated to blow out cool air into the room (cooling), and then the pipe. Through the line 42, the four-way valve 31, the cold water pump 21, and the pipe line 43, a low temperature heat exchanger (heat source for heat absorption)
Return to 13.

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 embodiment. 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 pipe line 44, the hot water pump 20, the three-way valve (switching means) 500, the three-way valve (heat transfer circuit switching means) 400, and the four-way valve. After passing through 30 and the pipe 41 to the indoor heat exchanger 201, the indoor fan 203 is rotated there to perform heat exchange, and after sending hot air into the room (heating), the pipe 42, the four-way valve 31, and hot water supply It returns to the intermediate temperature heat exchanger (heat source for heat radiation) 11 through the 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.

Therefore, according to this embodiment, when the outside air temperature is low, for example, rapid heating can be performed irrespective of the startup of the hot gas engine 1.

In rapid heating, three-way valve (switching means) 500
The hot water radiated by the medium temperature heat exchanger (heat source for heat radiation) 11, the conduit 44, the hot water pump 20, the three-way valve (switching means) 500, the bypass pipe 53, the hot water heating heat exchanger 93, the bypass. After passing through the pipe 55, the four-way valve 30, and the pipe 41 to the indoor heat exchanger 201, the indoor fan 203 is rotated to perform heat exchange, and hot air is blown into the room (heating). It returns to the intermediate temperature heat exchanger (heat source for heat radiation) 11 through the valve 31, the hot water supply heat exchanger 60, and the pipe line 47.

According to this, the hot water radiated by the intermediate temperature heat exchanger (heat radiation source) 11 is further heated by the hot water heating heat exchanger 93 and then flows into the indoor heat exchanger 201. Only, the room can be heated rapidly. In addition, since hot water is heated by the heat exchanger 93 for heating hot water and then flows into the indoor heat exchanger 201, even if the startup of the hot gas engine 1 is slow at startup, regardless of that, the room is rapidly heated. It is possible to obtain effects such as heating.

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, heated by the hot water passing therethrough, and 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 depending 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 embodiment, when there is no request for cooling or heating operation but only for hot water supply operation, the three-way valve 500 remains in the switching state shown and the three-way valve (heat transfer circuit switching means) is used. 400 is switched. Further, the four-way valves 30 and 31 are switched to the positions shown by the solid lines.

According to this, the hot water radiated by the medium temperature heat exchanger (heat radiating heat source) 11, the pipe line 44, the hot water pump 20, the three-way valve 500, the three-way valve (heat transfer circuit switching means) 4
00, bypasses the indoor unit 200, flows to the hot water supply heat exchanger 60 through the pipe line 48, and then returns to the intermediate temperature heat exchanger (heat radiation heat source) 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 is placed.
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, the heat from the outside air is absorbed 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. .

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

When there is no request for cooling or heating operation but only for hot water supply operation, the hot gas engine 1
The following embodiments are provided so that it is possible to sufficiently cope with the operation of the vehicle. As shown in the figure, the external water supply pipe 70
A three-way valve (hot water supply circuit switching valve) 410 is connected to the three-way valve (hot water supply circuit switching means) 410, and a pipe line 49 that bypasses the hot water supply heat exchanger 60 is connected to 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 meet 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.
Alternatively, it is possible to cope with the operation when there is no request for hot water supply.

The energy saving effect in each of the above-described embodiments 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 each of the above embodiments, 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 that releases the heat to the temperature (Tc) of the heat source that pumps the heat. In the case of the embodiment, since the temperature of hot water that is a heat source for releasing heat is cooled with water (for example, the standard temperature of tap water during cooling is about 27 ° C.), 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 each of the above-described embodiments is equipped with an actuator (not shown) for operating the valve or the like, and this device 101 has these actuators 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 embodiments of the present invention, it is obvious that the present invention is not limited to the above embodiments.

For example, in the above-mentioned embodiment, the Stirling cycle heat pump is used as the hot gas engine 1. However, the hot gas engine 1 is 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-described embodiment, 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.

[0053]

According to the first aspect of the present invention, when there is a demand for rapid heating, the switching means is switched and hot water is caused to flow through the auxiliary heating means to warm the hot water, and then the hot water is used in the room. Since it can be flowed to the heat exchanger, the room can be rapidly heated.

According to the second aspect of the present invention, the hot water supply heat exchanger is connected to the heat transfer circuit connected to the heat radiation heat source, and the external heat supply water or circulating water is passed through the hot water supply heat exchanger for heating and hot water supply. In particular, the heat released to the outside air during cooling can be effectively used by utilizing it for hot water supply. Further, the above-mentioned rapid heating becomes possible by using the auxiliary heating means, and when it is desired to raise the temperature of the hot water heated and supplied, the auxiliary heating means is operated to adjust the hot water supply temperature to, for example, 80%.
It can be raised to about 0 ° C.

According to the third aspect of the present invention, since the heat transfer circuit switching means is provided, for example, when there is no request for cooling or heating but only a request for hot water, an outdoor heat exchanger or an indoor heat exchanger is provided. Since the hot water can be passed through the hot water supply heat exchanger by bypassing the exchanger, it is possible to heat the externally supplied water or the circulating water to supply hot water only by operating the hot gas engine. Further, since the auxiliary heating means is provided in the hot water supply circuit, it is possible to raise the temperature of the heated / hot water.

In the invention according to claim 4, since the hot water supply circuit switching means is provided, for example, when there is only a hot water supply request, the external supply water or the circulating water is heated without operating the hot gas engine. Can supply hot water. Alternatively, it is possible to respond even when there is no request for hot water supply.

According to the invention described in claim 5, since each device other than the indoor unit is housed in the outdoor unit, each device can be compactly assembled.
