    Principle of EVRA40 ammonia refrigeration solenoid valves:
    Compressors, condensers, throttles and evaporators in refrigeration systems are the four most basic components. They are connected in series by pipes to form a closed system. The refrigerant ammonia continuously circulates in the system, changes state, and exchanges heat with the outside world.

     

    The workflow of EVRA40 ammonia/NH3 refrigeration solenoid valve is as follows:
    The liquid ammonia absorbs the heat of the coolant in the evaporator, evaporates into a low-pressure low-temperature ammonia gas, is sucked into the compressor, is compressed into a high-pressure high-temperature ammonia gas, is discharged into the condenser, and is cooled in the condenser by the cooling water. Condensation is a high-pressure ammonia solution, and the throttle valve is throttled to a low-temperature and low-pressure ammonia liquid, and again enters the evaporator to absorb heat and evaporate, thereby achieving the purpose of circulating refrigeration. In this way, ammonia undergoes four basic processes of evaporation, compression, condensation, and throttling in the system to complete the refrigeration cycle.

     

    The ammonia refrigaration systems:

    In ammonia refrigeration systems, refrigeration compressors are primarily piston and screw refrigeration compressors. The former appears earlier and is the most widely used. The utility model has the advantages of convenient use, reliable operation, rich management experience, large refrigeration capacity, low energy consumption per unit refrigeration, simple processing and low cost; the disadvantage is that the compressor is large in volume, consumes a large amount of metal, has a large area, and has many wearing parts. , high maintenance costs. The output of a single unit cannot be too large, and it is difficult to adjust the energy steplessly. The screw compressor has the advantages of simple structure, small volume, less wearing parts, light weight, small vibration, high volumetric efficiency, insensitivity to wet compression, and stepless adjustment. The disadvantage is that the unit cooling capacity is lower than the cooling capacity of the piston. The model is slightly higher, and the fuel injection cooling makes the oil system complex and bulky, with high fuel consumption, high noise, and high precision of screw machining. In contrast, since the screw compressor can easily control the exhaust gas temperature, it will be more widely applied to an ammonia refrigeration system.

     

    Shell and tube heat exchangers were more common before the 1980s. However, its quality, floor space, heat transfer performance and disassembly flexibility are not as good as plate heat exchangers. Plate heat exchangers have been used in fluorine systems for more than 20 years. The root cause of not using them in ammonia systems is that the solder contains copper. When the CFC and HCFC limits are disabled and ammonia is reused, in order to reduce the amount of ammonia in the system, people tend to use plate heat exchangers. Therefore, many improvements have been made on the basis of conventional plate heat exchangers. Condenser, evaporator, oil cooler, subcooled heat exchanger and brine cooler.
