(1) Simply edit :
Air cooled screw water chiller adopt international known brand screw compressor, form a complete set of high quality and efficient production to copper tube condenser, evaporator and the control element of world famous brand, the unit has small volume, low noise, big power, long life, the advantages of simple operation, its beautiful exquisite appearance design and reliable and stable highly effective quality excellence in the similar products!
(2) Working principle of air-cooled screw chiller :
The air cooling screw chiller is known as the air cooling screw chiller because its key component, the compressor, is screw type. After adiabatic compression of the compressor, it becomes high temperature and high pressure. The compressed gas refrigerant, in the condenser, condenses under constant pressure, changes into a liquid refrigerant after condensation, and then expands to a low pressure through the throttle valve, turning into a gas-liquid mixture. The liquid refrigerant at low temperature and low pressure absorbs the heat of the cold substance in the evaporator and becomes the gas refrigerant again. The gaseous refrigerant is piped back into the compressor and begins a new cycle. These are the four processes of the freezing cycle. It is also the main working principle of screw chiller .
The air-cooled chiller directly USES the air condenser on the unit to discharge heat into the air. Water-cooled machines need to circulate water through an external cooling system. Heat is transferred to the air through cooling towers or cooling pools.
Screw unit is a medium - sized refrigeration unit. Water condensers are usually used. The advantage is that the amount of cooling is higher than that of air cooling. They are less affected by the environment. Performance is more stable. Air-cooled machines are used in areas where water is scarce or where water is not readily available.
