PROBLEM TO BE SOLVED: To reduce manufacturing cost by reducing the number of components.SOLUTION: A refrigerant circuit device 10 includes: a high pressure refrigerant introduction path 30 that has a first high pressure refrigerant pipe line 31 and a second high pressure refrigerant pipe line 32 each supplying a refrigerant compressed by a compressor 21 in a main path 20 to a heating interior heat exchanger; and a heat radiation path 40 for supplying the refrigerant that has passed through the heating interior heat exchanger to the main path 20. The refrigerant circuit device includes: a four-way valve 22 enabling switching to either of a first delivery state where an inlet 221 is communicated with a first outlet 222, a second delivery state where the inlet 221 is communicated with a second outlet 223, a third delivery state where the inlet 221 is communicated with a third outlet 224 and a fourth delivery state where the inlet 221 is communicated with the second outlet 223 and the third outlet 224; and control means 10b for controlling the four-way valve 22 to any of the delivery state when a cooling and heating operation is performed.SELECTED DRAWING: Figure 3 |
