[0031]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 14 is a refrigeration cycle diagram of the air conditioner according to the embodiment of the present invention. This air conditioner includes an indoor unit 40 and an outdoor unit 50, and a rotary compressor 2 for compressing refrigerant, a four-way valve 3, an indoor heat exchanger 5 including an indoor blower 4, and an electronic device as a decompression device. An outdoor heat exchanger 9 having an expansion valve 6 and an outdoor blower 8 is sequentially connected by a refrigerant pipe 10. In the heating operation, the refrigerant circulates in the refrigerant pipe 10 in the direction of arrow A.

The outdoor unit 50 has a heat storage source 13. The heat storage source 13 includes a closed heat storage container 14, a heating unit 17 including a heater for heating a heat storage material 16 made of antifreeze contained in the heat storage container 14, and the pressure in the heat storage container 14 is equal to or higher than a predetermined pressure. And a pressure releasing means 18 for releasing the pressure when the pressure becomes.

A refrigerant pipe 10 connecting the indoor heat exchanger 5 and the four-way valve 3 and a refrigerant pipe 10 connecting the outdoor heat exchanger 9 and the electronic expansion valve 6 are connected between the refrigerant pipe 10 and the refrigerant pipe 10. A heating refrigerant supply pipe 12 through which a part of the refrigerant circulating in the refrigerant can flow is provided. The heating refrigerant supply pipe 12 is a heat storage container 14
It is arranged to pass through.

Heated refrigerant supply pipe 1 close to indoor heat exchanger 5
The part 2 is provided with a two-way valve 20 for opening and closing the refrigerant to flow through the heating refrigerant supply pipe 12. The refrigerant branched from the refrigerant pipe 10 flows in the heating refrigerant supply pipe 12 in the direction of arrow B when the two-way valve 20 is open.

A temperature sensor 22 is provided on the outer wall of the heat storage container 14, and it is determined by the temperature sensor 22 whether the heating operation can be started. The outdoor heat exchanger 9 has a frost sensor 23 for detecting a frost state of frost adhering to the outdoor heat exchanger 9.
Are arranged. The detection results of the sensors 22 and 23 are sent to the control unit 24. The control unit 24 controls the overall operation of the air conditioner and opens and closes the two-way valve 20 according to the detection results of the sensors 22 and 23.

The heating operation mode is controlled by a remote controller (not shown) or the like.
When the operation mode is selected, the four-way valve 3 is turned on (energized) by the control unit 24, and the temperature detected by the temperature sensor 22 is equal to or higher than a predetermined value, and the heat capacity of the heat storage container 14 is sufficiently increased. If the frost sensor 23 determines that there is a large amount of frost, the control unit 2
4, the two-way valve 20 is opened, the indoor fan 4 and the outdoor fan 8 are operated, and the refrigerant circulates in the refrigeration cycle in the direction A in the drawing.

The high-temperature and high-pressure gas refrigerant discharged from the compressor 2 is guided by the four-way valve 3 and introduced into the indoor heat exchanger 5 and the heated refrigerant supply pipe 12. The refrigerant introduced into the indoor heat exchanger 5 radiates heat there and exchanges heat with the outside air, and the warm air is blown into the room by the indoor fan 4 to perform heating, and radiates heat inside the indoor heat exchanger 5 while condensing. The liquefied liquid refrigerant is decompressed by the electronic expansion valve 6 and then flows into the outdoor heat exchanger 9 where it evaporates and absorbs heat from the outside air due to the latent heat of vaporization of the liquid refrigerant to gasify it. The air exchange promotes the heat exchange.

On the other hand, the refrigerant introduced into the heating refrigerant supply pipe 12 passes through the open two-way valve 20 and passes through the heat storage container 14, is heated by the heat storage material 16 and is vaporized, and becomes a high-temperature gaseous refrigerant. Is sent to the outdoor heat exchanger 9. Thereby, when a large amount of frost is attached to the outdoor heat exchanger 9, the frost is released, and immediately after the start of the heating operation mode, it is possible to quickly proceed to the heating operation mode.
