Q: What is the working principle of a water chiller?
A: A water chiller compresses the refrigerant through a compressor. The refrigerant releases heat through condensation, expands and reduces pressure, then evaporates and absorbs heat, absorbing the heat of water, lowering the water temperature, and recirculating the cooling equipment.

 

Q: In which industries are water chillers mainly used?
A: Water chillers are widely used in industries such as plastic processing, electronic manufacturing, food refrigeration, medical equipment, and chemical reactions to provide constant temperature cooling for equipment or processes.

 

Q: How to clean the condenser of a water chiller?
A: The cleaning staff first turns off the water chiller, disassembles the condenser casing, and rinses the heat sink with a high-pressure water gun. Stubborn stains can be wiped with a special detergent, then dried and reinstalled.

 

Q: What should be paid attention to when installing a water chiller?
A: The installer needs to select a flat ground, ensure that the water chiller is sufficiently spaced from the wall and other equipment, that the connecting pipes are well sealed, and that the power supply voltage meets the equipment requirements.

 

Q: What is the daily maintenance of the water chiller?
A: Maintenance personnel check the chiller's operating temperature and pressure daily, clean the filter weekly, check the refrigerant level monthly, and regularly replace lubricating oil and filter elements.

 

Q: What should be done when the chiller is turned on for the first time after installation?
A: Before the first start-up, the installer checks the connections of each component, opens the valve, powers on the machine for a test, observes the chiller's operating sound, temperature, and pressure, and officially uses it after confirming that it is normal.
