Claims

[Scope of utility model registration request]

In a refrigeration system in which a compressor, a condenser, a solenoid valve for a refrigerant liquid pipe, an expansion valve, an evaporator, etc. are sequentially connected to form a refrigeration cycle, a flow path is disconnected on the inlet side of the solenoid valve for a refrigerant liquid pipe due to the temperature of the refrigerant liquid. A refrigeration device characterized by being provided with a strainer made of a shape memory alloy that increases or decreases its area.
