Equipment main structure:
1. Rack/water tank/shell compressor/shell evaporator/filter/pressure controller
2. High and low pressure gauge/constant temperature control/water-cooled condenser pipeline system Electrical control system

Material selection and characteristic description:
1. The rack is made of Q235A square steel and the outer shell is made of A3 sheet metal, with secondary spraying of colored paint;
2. The air conditioning unit is a fully enclosed compressor, and the temperature controller is a digital temperature controller;
3. Other major electrical components are of high quality;
4. Adopt water-cooled shell and tube heat exchanger.

The refrigeration system of a chiller unit consists of four basic parts: compressor, condenser, throttle, and evaporator. Connect the four major components in a certain order using copper pipes to form a closed system, which is filled with a certain amount of refrigerant.
The compressor sucks in low-temperature and low-pressure Freon gas from the evaporator, compresses it into high-temperature and high-pressure Freon gas, and then flows through a thermal expansion valve (capillary tube), throttling it into a low-temperature and low-pressure Freon liquid two-phase object. Then, the low-temperature and low-pressure Freon liquid absorbs heat from indoor air in the evaporator, and the cycle of compression condensation throttling evaporation is repeated.
