The condenser or condensing pressure in the liquid reservoir under the saturated liquid refrigerant throttling to evaporating pressure and evaporation temperature, refrigerant flow at the same time according to the change of refrigeration load into the evaporator.
General of the throttle body manual throttle valve, thermostatic expansion valve, a capillary tube, a floating ball valve and so on, the capillary is does not have the adjustment function, and the throttle valve can also regulate the refrigeration unit evaporator refrigerant flow into the, in order to adapt to the refrigeration load changes from and achieve the purpose of regulating the cooling capacity.
Manual throttle valve
Is the old-fashioned throttle valve. Mostly used for ammonia refrigeration equipment, manually adjust the valve hole of the circulation area to change to the fluid volume for evaporator. Usually in industrial chillers freon refrigeration system, the manual throttle valve as a backup valve installed in the bypass pipe on the road, side automatic throttle structure maintenance when in use.
Float regulating valve
According to the change of liquid level flow control valve, the throttle pressure and control the role of liquid level. It is a kind of automatic throttle valve, which is commonly used in the automatic regulation of the liquid level of the evaporator, the gas-liquid separator and the middle cooler. At present, it is mainly used in ammonia refrigeration equipment.
Thermal expansion valve
With the change of the refrigerant temperature at the outlet of the evaporator, the opening degree of the automatic regulating valve is controlled by the action of the temperature sensing mechanism to control the flow rate of the refrigerant. Thermal expansion valve mainly by the valve body, temperature and capillary, evaporator for no free surface, such as dry evaporator, snake tube evaporator and coil intercooler etc.. Is one of the most commonly used cold water machine throttle mechanism.
