Claims

[Scope of utility model registration request]

In a cooling system in which a compressor, a condenser, an aperture, and an evaporator are connected in this order through refrigerant piping, a four-way switching valve is provided in the refrigerant piping on the discharge side of the compressor, and the four-way switching valve is connected to water heat for hot water supply. A first refrigerant pipe having an exchanger and a second refrigerant pipe connected to the suction side refrigerant pipe of the compressor are connected, and the first
The water heat exchanger outlet side of the refrigerant piping is branched into two via a first switching means, and one third refrigerant pipe is connected to the refrigerant pipe between the condenser and the throttle via the second switching means, A cooling/hot water supply system characterized in that a fourth refrigerant pipe provided with the other hot water supply throttle is connected to the refrigerant pipe between the condenser and the second switching means, respectively.
