[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to a refrigerant-heated hot water heater/cooler.

BACKGROUND OF THE INVENTION As shown in FIG. 2, a conventional heat pump hot water heater/cooler includes a compressor 1, a four-way valve 2, a three-way valve 3, an indoor unit 4, a first capillary reach tube 5, a second capillary reach tube 6,

A sudden heat collection hot water supply cycle device comprising a capillary chineave 9, a first electromagnetic valve 10, the water/refrigerant heat exchanger 7, and the three-way valve 3 connected in sequence, the compressor 1, the four-way valve 2,
An atmospheric heat dissipation type cooling cycle device configured by sequentially connecting the outdoor unit 8, the second solenoid valve 11, the first capillary reach tube 5, the indoor unit 4, and the three-way valve 3, and the compressor 1 and the four-way valve 3. An atmospheric heat collection type heating cycle device configured by sequentially connecting a valve 2, the outdoor unit 8, the third capillary reach tube 9, the third solenoid valve 12, the indoor unit 4, and the three-way valve 3 to form a cycle; It is composed of a water heating and hot water supply system that connects a refrigerant heat exchanger 7, a water circulation pump 1a, and a hot water storage tank 14, and collects atmospheric heat to heat water for hot water supply or for heating through an indoor unit. I was supposed to do it. (For example, Japanese Unexamined Patent Application Publication No. 59-157459) Problems to be Solved by the Invention However, in the above configuration, generally, when the outside temperature falls, the hot water heating capacity and heating capacity tend to decrease. There was a problem that it could not be used in seasons where the outside temperature was low, such as in cold regions. On the other hand, high-pressure refrigerant or low-pressure refrigerant is heated with a gas burner, oil burner, etc., and a compressor is used as a refrigerant pump to form a heat transfer system.
There are refrigerant-heated heating and cooling systems that increase space heating or hot water supply capacity. In this system, the compressor is used as a refrigerant pump, so electricity for heat transfer is required, and the atmospheric heat collection cycle is stopped at low outside temperatures to utilize the amount of heat from refrigerant heating. As a result, there was a problem in that a large capacity burner section, etc. was required, resulting in an increase in size. Also,
This type of refrigerant heating system has the problem that the refrigerant leaks and becomes toxic when heated, and the corrosion resistance and durability of the refrigerant passage system in the burner section have become important issues.

Means for Solving the Problems In order to solve the above-mentioned problems, the refrigerant-heating type hot water heating/cooling device of the present invention includes a boiler hot water supply device exclusively for the hot water supply function, a heat pump refrigeration cycle device for performing air conditioning, and a heat pump refrigeration cycle device for heating and cooling. The condensed high-pressure refrigerant after heat utilization is guided through the cycle device, heated with hot water from the boiler hot water supply device, the heated refrigerant is heat-transferred without electricity, and is again superimposed with the high-pressure refrigerant of the heat pump refrigeration cycle device. This is a refrigerant-heating hot water heating/cooling machine consisting of a bubble pump type heat transfer device used for space heating.

Effect of the present invention With the above-described configuration, the refrigerant is heated with the hot water of the boiler water heater, the heat is transferred without electricity, and this is combined with the heat collected from the atmosphere and sent by the heat pump. They are used for heating by stacking the refrigerant on top of each other, and therefore, the refrigerant is not directly heated by the burner, so corrosion of the heat exchange part is reduced, and even if the refrigerant leaks, the burner heating will cause toxicity. There is no problem. In addition, since the heat of the refrigerant heated by hot water is transferred and utilized without electricity, it can be said that the system has an extremely high energy-saving effect. In addition, since this amount of transferred heat is used by superimposing the amount of heat generated by the heat pump of the conventional atmospheric heat collection type heat pump cycle device, it is possible to utilize a large amount of heat while saving power.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIG. 1, a compressor 1, a four-way valve 2, an indoor unit 4 having an air blower 3, a first expansion device configured in a parallel circuit of a first check valve 5 and a first expander 6, and a two-way valve 7 , second check valve 8
, an outdoor unit 11 having a second expansion device configured in a parallel circuit with a second expander 9, a blower device 10, and an accumulator 1.
An atmospheric heat collection type heat pump refrigeration cycle device is constructed by sequentially connecting the two. Further, a boiler type water heating device 1a, a hot water storage tank 14, and a water supply circuit consisting of the hot water storage tank 14, a water supply circuit 15, and a hot water supply circuit 16 are connected to form a boiler hot water supply device. Further, the boiler hot water supply system includes a hot water storage tank 14, a water circulation pump 17, a refrigerant heater 18 that heats the refrigerant with hot water, a first check valve 19 for heat transfer, a refrigerant control device 20, and a second check valve 21 for heat transfer. , connects the first expansion device, connects the refrigerant heater 18 and the discharge section of the compressor 1, and further connects the refrigerant control device 20.
The discharge section of the compressor 1 is connected via a two-way valve 22 to balance the pressure between the refrigerant control device 20 and the refrigerant heater 18, and the refrigerant vapor generated by heating the refrigerant is transferred to the discharge section of the compressor 1. A bubble pump type heat transfer device is configured to transfer heat via the air bubble pump.

Note that the solid arrow lines indicate the heating cycle, and the dotted lines indicate the cooling cycle.

In the above configuration, a part of the liquid refrigerant condensed in the indoor unit 4 and flowing out from the first expansion device is transferred to the second check valve 21 for heat transfer.
The liquid flows through the refrigerant control device 20 and is stored as a liquid reservoir. The liquid refrigerant in the refrigerant device 20 is heated at the same time as the two-way valve 22 is opened intermittently and dropped into the pressure-balanced refrigerant heater 18, and transformed into refrigerant vapor. This refrigerant vapor is superimposed on the refrigerant superheated vapor discharged from the compressor 1,
The heat is transferred to the indoor unit 4 and condensed by heat radiation from the indoor unit 4. This is because the amount of heat collected from the outdoor unit 11 is amplified by the heat pump of the compressor 1, and this amount of heat is superimposed with the amount of heat obtained by the refrigerant heater explained above, resulting in a low Even if the atmospheric heat collection decreases at outside temperature,
This has the effect of providing comfortable heating without reducing the heating capacity. Still, stop the water circulation pump and turn off the four-way valve 2.
? A cooling effect can be obtained by switching to the refrigerant cycle as shown by the dotted line and allowing the refrigerant to flow as shown by the dotted arrow.

Effects of the Invention As described above, the refrigerant heating type hot water supply heating/cooling machine of the present invention provides the following effects.

(1) The amount of heat collected from the atmosphere is amplified by the heat pump of the compressor, and the amount of heat obtained from the refrigerant heater is added to the amount of heat obtained from the refrigerant heater by the amount of heat from the boiler water heater, so it is possible to increase the heating capacity at low outside temperatures. can.

(2) Since the amount of heat obtained from the refrigerant heater is conveyed by a type of electric bubble pump, the energy saving effect is large.

(3) Refrigerant heaters use hot water to heat the refrigerant, so the refrigerant is not overheated, and the properties of the refrigerant are stable. At the same time, if there is a sudden refrigerant leak, toxic gas will be generated. It is safe and has no
