電力や灯油燃料を要するという欠点があつた。 It is well known that in conventional heat pump air-conditioning devices, the performance of the heat pump decreases as the outside temperature drops during heating operation, and that this device alone cannot adequately heat the room during severe cold weather. For this reason, various methods have been developed in the past to incorporate a heater into the device and use the heater to assist in performance, but there is a risk of fire. Also, as another method,
As an auxiliary heat source for the heat exchanger on the heat source side, heating of refrigerant using a heater and combustion of kerosene are available, but these have the disadvantage of requiring a large amount of power consumption and kerosene fuel.

である。 Next, the operation of this heating and cooling device will be explained. First, the refrigeration cycle during heating is basically the same as the existing cycle, with the compressor 6 operating in conjunction with the operation of the indoor unit (no number), and the indoor heat exchanger 15 operating as a condenser. Then, the outdoor heat exchanger 9 operates as an evaporator. Also, when heating
The heat of the compressor 6 heats the metal hydride 4 in the metal container 2, and high-pressure hydrogen gas is released and enters the metal container 3 through the hydrogen pipe 11 and valve 10, and the metal hydride therein is heated. It is occluded by compound 5. At this time, the stored heat generated in the container 3 is transferred to the outdoor side blower 1.
2, the heat is exchanged through the fins 8 and becomes warm air, which heats the outdoor heat exchanger 9 and acts as an auxiliary heat source. In this way, the heating effect during heating operation is improved. Next, when the internal pressures of the metal containers 2 and 3 are balanced and the movement of hydrogen gas is stopped, the valve 10 is closed, the solenoid valve 13 is closed, and the solenoid valve 14 is opened to switch the refrigerant flow path, and the heat exchange pipe A low-pressure suction refrigerant is passed through the metal container 2 due to the refrigerant heat.
The metal hydride 4 inside is cooled. As a result, the pressure inside the metal container 2 decreases. On the other hand, the metal hydride 5 in the metal container 3 is heated by heat exchange with outside air via the fins 8 by the outdoor fan 12. At this time, when the valve 10 is opened again, the hydrogen gas in the metal hydride 5 is released due to the pressure difference, enters the metal container 2, and is occluded in the metal hydride 4 therein. The absorbed heat generated here is constantly cooled by the low-pressure suction refrigerant, so the movement of hydrogen due to the pressure difference,
There is no problem in heating the compressor 6. In this way, one cycle of heat exchange operation between the metal containers 2 and 3 is completed, but as a modified example, when the storage heat of the metal hydride 5 is utilized by the heat of the compressor 6, the valve 10 is turned on and off or the hydrogen flow rate is controlled, and low pressure suction is performed. When the metal hydride 4 is cooled by a refrigerant, if hydrogen is transferred instantaneously, it can be used as a continuous auxiliary heat source for heating. Of course, it is also possible to open the valve 10 and use it only when necessary, such as when the outdoor heat exchanger 9 is frosted, rather than as a constant heating auxiliary heat source.

よくなる。 As described above, the heating device for heating and cooling of the present invention absorbs and releases hydrogen from the metal hydride by heating and cooling the metal hydride using compressor heat of the heating and cooling device, low-pressure suction refrigerant, and air. Since heating is performed using the transfer of heat that occurs, the heating effect can be safely and economically enhanced. As an embodiment, if the outdoor heat exchanger is heated with a metal container, the operation efficiency of the air-cooled heat pump in winter improves.
