walk-in cooler two-stage compression freon refrigeration system
walk-in cooler two-stage compression freon refrigeration system walk-in cooler one-stage throttling intermediate complete cooling cycle is designed to add a gas-liquid heat exchanger to the system This not only can further reduce the temperature of the high-pressure liquid and increase the unit refrigeration capacity, but more importantly, it is to increase the suction temperature of the low-pressure compressor to improve the lubrication conditions of the compressor and avoid frosting on the outer surface of the cylinder. Wait. The system also uses an oil separator device with automatic oil return, a thermal expansion valve type of liquid supply adjustment, and a solenoid valve to automatically cut off the liquid supply line when the compressor stops running.
two-stage compression two-stage throttling refrigeration cycle two-stage compression two-stage throttling refrigeration cycle is used in some refrigeration compressor units (such as centrifugal compressor units, screw compressor units and scroll compressor units). it uses intermediate air supplement, and its working process is as follows. The low-pressure steam with the pressure Po generated in the evaporator F is first sucked by the low-pressure stage of the compressor A and compressed to the intermediate pressure Pm, and merges with the gas separated from the gas-liquid separator D (commonly known as the economizer) and enters the person. The high-pressure stage is further compressed to the condensing pressure pk, and then enters the condenser B to be condensed into vapor. After the liquid from the condenser is throttled to the intermediate pressure Pm by the first-level throttling element C, it enters the gas-liquid separator D (commonly known as the economizer) for gas-liquid separation, and the gas is used as the intermediate supplement gas to directly interact with the low pressure of the compressor A The stage exhausts merge into the high-pressure stage compression; the separated liquid is throttled to the evaporation pressure Po by the secondary throttling D element E, and then enters the evaporator F to evaporate to produce cold energy, and the evaporated low-pressure vapor is used by the compressor A The low-pressure stage suction. The cycle goes on again and again. Since the gas separated by the gas-liquid separator D is not compressed by the low-pressure stage, it is directly used as an intermediate supplementary gas to enter the high-pressure stage for compression, which reduces the power consumption of the low-pressure stage and increases the unit refrigeration capacity, which improves the efficiency of the unit About 7%.
