The cooling water unit is a commonly used refrigeration equipment that is widely used in industrial production, commercial construction, and comfort air conditioning.

Working principle of cooling water unit

The working principle of the cooling water unit is mainly based on the refrigeration cycle. The refrigeration cycle consists of a compressor, condenser, expansion valve and evaporator. The functions of each component will be introduced one by one below:

1. Compressor: The compressor is the core component of the cooling water unit and is responsible for compressing low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas. This process requires a certain amount of electrical energy.

2. Condenser: The condenser conducts high-temperature and high-pressure gas refrigerant to the cooling medium (usually water or air), cooling the gas through heat transfer and condensing it into a liquid. The cooling medium absorbs the heat of the refrigerant and discharges it, causing the temperature of the refrigerant to drop.

3. Expansion valve: The expansion valve is a throttling device that controls the flow and pressure of refrigerant to flow the refrigerant from the high-pressure area into the low-pressure area. This process reduces the temperature and pressure of the refrigerant.

4. Evaporator: The evaporator is another important component of the chiller. It changes the refrigerant from a liquid state to a gas state by absorbing heat from the surrounding heat source. This process causes the temperature around the evaporator to drop, thereby achieving a cooling effect.

Through the above cycle process, the chiller can absorb heat from the room or equipment and discharge the heat through the cooling medium and condenser, thereby achieving the cooling effect.
