Claims

[Scope of utility model registration request]

(1) In an air conditioner in which a refrigeration cycle is configured by connecting a compressor, a heat source side heat exchanger, and a user side heat exchanger formed by connecting a plurality of heat exchangers in parallel in a closed circuit, A solenoid valve for room temperature control is inserted in series in each of the plurality of heat exchangers on the user side, and a first solenoid valve for flow rate control and an outflow valve are inserted between the discharge side pipe and the suction side pipe of the compressor. The first one is inserted in series with a pressure regulator that controls the flow rate according to the side pressure.
A second electromagnetic valve for flow rate control and a pressure reducing device are connected by a bypass pipe, and a pipe line connecting the heat source side heat exchanger and the usage side heat exchanger and a suction side pipe line of the compressor are connected. are connected by a second bypass pipe inserted in series, and an electric control device is provided for controlling the first and second solenoid valves for controlling the flow rate based on the opening and closing of the solenoid valve for controlling the room temperature. Air conditioner.

(2) The pressure regulating device inserted into the first bypass pipe includes a pressure regulating valve whose opening degree increases as the pressure on the outflow side decreases, and a capillary tube connected in parallel to this pressure regulating valve. An air conditioner according to claim 1 of the utility model registration claim consisting of:

(3) The pressure reducing device inserted into the second bypass pipe is a temperature-type expansion valve that controls the pressure reduction rate according to the temperature of the suction side pipe of the compressor. Air conditioner as described in section.
