A refrigeration controller is arranged on the lower surface of the front face of a valve body of the refrigerant throttling device body. A refrigeration controller body is a cuboid fixing support. The thinner end of the fixing support is provided with a screw locating hole. A screw penetrates through the screw locating hole and is fixed on the valve body. A thermistor is arranged in the valve body and is close to an evaporator liquid-state end connector. Two signal lines connected with the thermistor are respectively educed from the thicker end of the fixing support. The refrigerant throttling device solves the problem that an existing throttling device can not directly monitor temperature, omits an extra temperature monitoring device for a refrigeration system, and saves hardware cost and utilization space. A temperature monitoring position can directly monitor the temperature of refrigerants. Temperature monitoring accuracy is improved.
