チューブである。Conventional configuration and problems The conventional air heat source type heat pump air conditioning system has a refrigerant circulation circuit as shown in Figure 1. During heating operation (the flow of refrigerant is shown by the solid line), outdoor heat is used as an evaporator. It is necessary to remove the frost that has formed on the exchanger 3 by performing a defrosting operation (the flow of the refrigerant is shown by a broken line, the same as during cooling) at regular intervals. At this time, the indoor heat exchanger 2 becomes an evaporator, which has the disadvantage of lowering the indoor temperature during heating. In the figure, 1 is a compressor, 4 is a four-way switching valve for the /1 medium circuit, and 5 is a capillary tube.

ことにより室温の低下を防ぐものである。Structure of the Invention The present invention provides an outdoor refrigerant-to-air auxiliary heat exchanger that serves as an evaporator during heating and a condenser during defrosting, in a refrigerant circulation circuit that constitutes a refrigeration cycle in a conventional heat pump air conditioning system.
A three-way switching valve for the refrigerant circuit and a capillary tube for refrigerant distribution are added. Moisture in the air passing through the outdoor refrigerant-to-air main heat exchanger, which serves as an evaporator during heating, is removed by the air auxiliary heat exchanger to prevent frost formation on the main heat exchanger. By removing the frost that has formed on the exchanger through defrosting operation using the latent heat of vaporization in the air main heat exchanger as a heat source, the ability of the indoor heat exchanger to be maintained even during defrosting is eliminated, while reducing the capacity of the air main heat exchanger due to frost formation. By acting as a condenser, it prevents the room temperature from dropping.
