Classification and main performance of HVAC chillers

Commonly used chillers are divided into piston type, screw type, centrifugal type, and vortex type chiller according to the type of refrigeration compressor used. Their evaporators and condensers generally use shell and tube heat exchangers, the throttling device uses thermal expansion valves, the refrigerant is freon

Compressor overheating

The compressor is overheated, causing it to stop shortly after start-up (protector action). Please check whether it is:; Insufficient or excessive refrigerant, please fill the leak and evacuate, add enough refrigerant or release excess refrigerant. The capillary assembly (including the filter) is clogged and the suction temperature rises. Please replace the capillary assembly.
