Claims

[Claims for Utility Model Registration] A single outdoor unit A equipped with a compressor 1, a four-way switching valve 2, and an outdoor coil 3 is formed by branching the liquid pipe 4 and gas pipe 5 of this outdoor unit A, respectively. Branch liquid pipes 4B and 4C
and indoor coil 15B via branch gas pipes 5B and 5C.
, 15C, in which the branch liquid pipe 4 is connected to a plurality of indoor units B and C.
Each of B and 4C consists of check valves 7B and 7C and heating capillary tubes 5B and 6C, and an indoor coil 15B.
, 15C to the outdoor coil 3, and each heating pressure reducing mechanism 8B, f3C is equipped with a check valve 10B, an IOC, and a cooling capillary tube 9B, 9C, a cooling pressure reducing mechanism 11B, IIC that allows only the refrigerant to flow from the outdoor coil 3 to the indoor coils 15B, 15C, and an energization mechanism that controls opening and closing of only the refrigerant flow from the outdoor coil 3 to the indoor coils 15B, 15C. A series circuit with open type solenoid valves 20B and 20C is connected in parallel, and the solenoid valve 20B. 20C, indoor unit during cooling) B, C cooling switches 33B, 33C and indoor temperature controllers 38B, 38
In response to the cooling operation/stop signal from C, a valve opening/closing signal is sent to each indoor unit B. C cooling switches 33B, 33C and indoor temperature controller 3
Heat pump type % type % characterized by connecting a valve control circuit
