Claims

[Claims for Utility Model Registration] (1) A circuit that is cyclically connected to the compressor, condenser, expansion valve, and main evaporator installed in the refrigerator, and the expansion valve of the circuit and the main evaporator 9b are connected in parallel. A device for controlling the flow rate of refrigerant in a refrigerant circuit comprising a connected sub-evaporator 10b, comprising a valve means for adjusting the refrigerant flow rate connected in series with the sub-evaporator 10b, and an air load amount near the sub-evaporator 10b. A refrigerant control device comprising: a detection means for detecting a detection; and a controller that opens a valve means when the load increases and closes the valve means when the load decreases according to an input signal from the detection means. - (2) Utility model registration Scope of the Claims In the device according to claim 1, the detection means includes a temperature detection means 17 and a wind speed detection means 16, and the controller receives signals from the temperature detection means 17 and the wind speed detection means 16. A refrigerant control circuit comprising a thermoelectric expansion valve 14 which outputs a voltage proportional to the logical product of , to a valve means, the valve means comprising a thermoelectric expansion valve 14 which opens and closes the valve in accordance with the voltage output from the controller. (3) In the apparatus set forth in claim 1 of the utility model registration claim, when the differential pressure between the static pressure introduced from the vicinity of the outlet of the sub-evaporator and the outside pressure by the valve means and the controller becomes equal to or higher than a predetermined value. 1. A refrigerant control circuit comprising: a circuit that closes a valve means at the same time.
