commercial refrigeration solenoid valve, pressure pilot valve, temperature pilot valve and main valve operation principle of each valve
this commercial refrigeration control method A higher control accuracy can be obtained, generally within ±1℃.
electric pilot valve + main valve action principle: electric pilot valve is a pilot valve with an electric actuator. The electric actuator is controlled by a temperature regulator with proportional integral function. As long as the commercial refrigeration temperature deviates from the given value, the temperature regulator has an electric signal to the electric actuator, and the latter is based on the signal law obtained. If the opening degree of the pilot valve is changed proportionally, the opening degree of the main control system valve is also changed accordingly to achieve the purpose of stabilizing the temperature of the commercial refrigeration. Because the temperature regulator has integral characteristics, the static deviation of the cabinet temperature is about 0°C. In order to prevent the evaporation temperature from being too low during the adjustment process, the electric pilot valve can be equipped with a limit device. This kind of adjustment method runs stably and has high control accuracy, which is suitable for occasions requiring precise temperature control. Condensing pressure regulation and its control components, commercial refrigeration. Too high condensing pressure in the refrigeration system will increase the power consumption of the compressor and damage the equipment. Too low pressure will reduce the pressure difference of the refrigerant and affect the flow. Therefore, the commercial refrigeration refrigeration system must Maintain a constant condensing pressure to ensure the normal operation of the refrigeration device.
