commercial refrigeration evaporating pressure adjustment and its control components
In commercial refrigeration refrigeration devices, evaporative pressure regulating valves are generally used to automatically control the evaporation pressure. The main function of its control: ①Maintain the constant evaporation pressure, reduce commercial refrigeration temperature fluctuations, ensure the quality of refrigerated items, and reduce dry consumption: ②For the case of one machine with multiple cabinets, the evaporator in different cabinet temperatures can be changed Operate under evaporation pressure. According to the different control capacity, the evaporative pressure regulating valve can be divided into two categories: direct-acting type and pilot valve and main valve combined control type. The former is used on small devices and the latter is used on large devices. At present, the commonly used methods of controlling evaporation pressure mainly include the following.
Directly use the evaporation pressure regulating valve to adjust the evaporation pressure. This is the most common method for small and medium commercial refrigeration. It can be used to adjust the evaporation pressure of one machine and multiple cabinets. It is mainly installed at the outlet of the evaporator with higher temperature. In one machine with three cabinets, since the refrigerating temperature of each cabinet is different (fish cabinet -10℃, dairy cabinet 2℃, vegetable cabinet about 5℃), the evaporation temperature (ie, evaporation pressure) of each commercial refrigeration evaporator is required to be different. The evaporation temperature of the vegetable cabinet is the highest, followed by the dairy cabinet and the fish cabinet the lowest. Since the suction pressure of the compressor during operation is adjusted according to the evaporation pressure of the low-temperature cabinet, at this time, in order to realize that the three evaporators can work at three different evaporation temperatures, the high-temperature cabinet (dish cabinet, dairy The outlet of the evaporator of the cabinet) is equipped with an evaporation pressure regulating valve (also called a back pressure valve) to keep the pressure before the valve at the required evaporation pressure. After the valve is throttled, the pressure after the valve is the same as the suction pressure. This achieves the purpose of each evaporator working under its own required evaporation pressure and meets the requirements of commercial refrigeration for refrigerated food.
