Claims

[Claims for Utility Model Registration] One outdoor unit A is equipped with a compressor 1, a four-way switching valve 2, and an outdoor coil 3, and the liquid pipe 4 and gas pipe 5 of this outdoor unit A are branched. Branch liquid pipes 4B, 4 formed by
C and branch gas pipe 5B. In the heat pump type air-conditioning system in which a plurality of indoor units B and C each having indoor coils 15B and 15C are connected via 5C, the branch liquid pipe 4B. Each of 4C consists of a check valve 7B, 7C and a heating capillary tube 5B, 5C, and an indoor coil 15B.
, 15C to the outdoor coil 3, and a branch liquid pipe 4B between the heating pressure reducing mechanism 3B, f3C and the indoor coil 15B, 15C. 4C, from the outdoor coil 3 to the indoor coil 15B,
Electromagnetic valves 20B and 20C of the energized open type that can control the opening and closing of only the refrigerant flow to 15C are provided, and check valves 10B, IOC, and cooling capillary tubes 9B are installed only in the respective heating pressure reducing mechanisms 8B and f3C. . C cooling switch 33B. 33C and indoor temperature controllers 38B, 38C, and sends out valve opening/closing signals based on the cooling operation/stop signals from the cooling switches 33B, 33C and indoor temperature controller 38B of each indoor unit B, C. When all the signals from 38C are cooling stop signals, a valve open signal is sent for a certain period of time, while each indoor unit B during heating,
When any of the signals from the heating switches 35B, 35C and the indoor temperature controllers 38B, 38C of the indoor units B and C is a heating operation signal, a valve open signal is sent out, and each indoor unit B,
C heating switches 35B, 35C and indoor temperature controller 38B. Constant when all signals from 38G are heating stop signals
. A heat pump type air-conditioning device characterized in that a valve control circuit X that sends out a time valve open signal is connected.
