Chillers: Responsible for generating low temperature cooling water to meet specific process or air conditioning requirements.
Cooling tower: responsible for dissipating heat and lowering the temperature of the circulating water.
Circulating water pumps: provide power to the entire system to move the cooling water through the pipes.
Heat exchanger: enables heat transfer between the waste heat generated in the production process and the cooling water.
Piping, valves and instrumentation: connects the components and controls the direction of water flow and monitors the system operating status.
Introduction of chiller plant
The chiller plant absorbs heat from the cooling water and transfers it to the condenser through a compression refrigeration system to reduce the temperature of the cooling water to the desired range. The common compression refrigeration systems are screw, centrifugal and piston type.
a. Compressor: The core component of the refrigeration system, responsible for compressing the refrigerant.
b. Evaporator: Here the refrigerant absorbs the heat from the cooling water and brings down its temperature.
c. Condenser: Here the refrigerant releases heat and liquefies, transferring the heat to the cooling tower for cooling.
d. Expansion valve: used to regulate the flow and pressure of refrigerant.
e. Control system: monitors and controls the operating status of the chiller to achieve optimal operation.
