FIG. 1 is a configuration diagram of a cooling and heating air conditioner according to a first embodiment of the present invention. This cooling / heating air conditioner has a structure in which a switch 7 is additionally provided as compared with the conventional example, and is configured to carry out cooling / heating by transporting hot water during heating and cold water to the indoor heat exchanger during cooling. FIG. 1 shows the flow direction of the secondary fluid during the heating operation. Here, as the secondary fluid, a refrigerant such as water, an antifreeze mixed with ethylene glycol or propylene glycol, or a fluorocarbon using latent heat is used. In the following description of the embodiment, a case where water is used as the secondary fluid will be described. At the time of heating, the water that has been heated by the condenser 6 to become hot water flows into the indoor heat exchanger 3 through the flow path indicated by the solid line of the switch 8. The heat is released into the room by the indoor heat exchanger 3 and then flows along the flow path shown by the broken line of the switch 7 and returns to the condenser 6 through the flow path shown by the solid line of the switch 9. Further, the water that has become cold water in the evaporator 5 passes through the flow path shown by the solid line of the switch 8, further flows along the flow path shown by the broken line of the switch 7, and flows into the outdoor heat exchanger 4. . Then, after exchanging heat with outdoor air, it flows through the flow path shown by the solid line of the switch 9 and returns to the evaporator 5. On the other hand, during cooling, only the switch 8 and the switch 9 are switched and the switch 7 is kept as it is, so that the water that has become hot water in the condenser 6 passes through the flow path indicated by the broken line of the switch 8. It flows through the flow path shown by the broken line of the switch 7 and flows into the outdoor heat exchanger 4. Thereafter, after the heat is released to the outside air by the outdoor heat exchanger 4, the heat flows along the flow path indicated by the broken line of the switch 9 and returns to the condenser 6. Further, the water that has become cold water in the evaporator 5 passes through the flow path shown by the broken line of the switch 8 and flows into the indoor heat exchanger 3 to exchange heat with the indoor air. Thereafter, the water passes through the flow path shown by the broken line of the switch 7, further flows along the broken line of the switch 9, and returns to the evaporator 5. When pumping heat from outside air during heating, frost adheres if the humidity is high and the outside air temperature is low.

取り除くことが可能となる。The operation of the deicing method for the air conditioner having the above-described configuration will be described below. At the time of de-icing, the hot water heated in the condenser 6 flows along the solid line of the switch 8 and flows into the indoor heat exchanger 3 by switching the flow path indicated by the broken line of the switch 7 to the flow path indicated by the solid line. Then, after warming the indoor air, the flow enters the flow outdoor heat exchanger 4 through the flow path indicated by the solid line of the switch 7 and releases heat to the outdoor air. After that, it flows along the solid line of the switch 9 and flows into the evaporator 5 to further lower the water temperature. Thereafter, the water returns to the condenser 6 through the flow path indicated by the solid line of the switch 8, along the solid line of the switch 7, and further through the flow path of the solid line of the switch 9. In such a flow path, the hot water once flows through the indoor heat exchanger 3 and then flows into the outdoor heat exchanger 4, so that the temperature decreases by the amount of heat released to the indoor air. However, in De Ice,
Since only the amount of heat in the hot water sufficient to bring the fin surface of the outdoor heat exchanger 4 to 0 ° C. or higher is sufficient, it is possible to melt frost adhering to the fin surface. De-ice is performed by the above operation. Further, by controlling the flow direction of the water by switching the switch 7 as described above, since the warm water flows into the indoor heat exchanger 3, the heating operation is stopped due to the cold water flowing into the indoor heat exchanger 3. It is possible to remove the frost without happening.
