INTEGRATED VENDING MACHINE REFRIGERATION UNIT can be divided into 4 systems, namely water system, fluorine system, oil system and electronic control system, the oil system refers to the lubricating oil system.
Generally, INTEGRATED VENDING MACHINE REFRIGERATION UNIT is divided into 4 parts, namely compressor, condenser, evaporator, throttle valve (expansion valve).
The compressor is the main component that provides power for the freon cycle, and is also the energy-consuming component of the INTEGRATED VENDING MACHINE REFRIGERATION UNIT. It is generally driven by a motor, and there are common screw compressors and scroll compressors.
The main function of the condenser is to provide conditions for freon heat exchange. The freon discharged from the compressor is a high temperature and high pressure gas, and the freon is cooled into a low temperature and high pressure liquid in the condenser. The refrigerant of the condenser generally has two forms of water cooling and air cooling, and there is a cooling tower in the water cooling form.
The main function of the evaporator is to provide conditions for the evaporative heat exchange of Freon. Freon flows from a high temperature liquid through the throttle valve and then evaporates, and absorbs frozen water (sometimes not necessarily frozen brine, but also other refrigerants such as ethylene glycol) through evaporation. ) in the heat to complete a refrigeration process.
The main function of the throttle valve (expansion valve) is to control the flow of freon, which is generally installed between the liquid storage tank and the evaporator. The agent absorbs heat in the evaporator to achieve the cooling effect.
The above is an introduction to the basic principles of INTEGRATED VENDING MACHINE REFRIGERATION UNIT, I hope it will help you.
