冷暖房装置。 In an air-conditioning system having a refrigerant circuit that includes a compressor 1, a heat source coil 2, a pressure reducer 3, a user coil 4, and a four-way switching valve 5, and in which the refrigerant flow direction can be switched, the user coil is of an air-to-air type. An auxiliary coil 7 is installed in parallel on the leeward side of the air flow path passing through the coil 4,
A reversible flow type first electric valve 8 that can reduce pressure and control the flow rate is interposed in the middle of the second liquid pipe 12 that connects the pressure reducer 3 and the user-side coil 4, and the auxiliary coil 7
One end of the coil is connected to the second coil via a second electric valve 9 of a reversible flow type that can reduce pressure and control the flow rate.
A branch connection is made to a portion of the liquid pipe 12 between the pressure reducer 3 and the first electric valve 8, and the other end of the coil is connected to the heat source side coil 2 and the pressure reducer 3 through a third liquid pipe 13. A switching valve device 10 is interposed between the third liquid pipe 13 and a gas pipe 14 which is branch-connected to the first liquid pipe 11 and further connects the utilization side coil 4 and the four-way switching valve 5. By switching the switching valve device 10, the user coil 4 and the auxiliary coil 7
A heating and cooling device characterized in that the four-way switching valve 5 and the first liquid pipe 11 can be alternately connected to each other.
