Sep 26, 2018 · The function of a process water chiller is to make cold water to cool a mold or other process equipment. As heat transfers from the process to the water, the water warms up. The chiller uses the warm water as a heat source to boil refrigerant in a part of the chiller called the evaporator.

Actuators for Chilled Water Valve – These chilled water actuators control the flow rate for a chilled water system in a data center. There are various sequence of operations for chilled water systems and the sequence of operation is usually always different from one chiller plant to another chiller plant.

EVAPORATOR PRESSURE REGULATING VALVES

EVAPORATOR PRESSURE REGULATING VALVES

The main function of an ORIT valve is to keep the evapora-tor pressure above some given point at minimum load condi-tions. Therefore, even though the valves are selected on the basis of the pressure drop at full load conditions, they should be adjusted to maintain the minimum allowable evaporator pressure under the actual minimum load conditions.

The other way is with a VFD, coupled with a transducer; it will maintain constant psi in your system by speeding up or slowing down the motor. Before you start adjusting the pressure in the system, which we factory set with every chiller at 20psi, be sure to verify that the jacket pressure ratings with the vessel manufacturer you went with.

Any type of chiller that functions using a consistent amount of clean coolant within a closed loop can be categorized as a recirculating chiller. Alternatively, open loop chillers provide cooling by regulating the temperature of a tank full of liquid, and pumping the liquid refrigerant through a heat exchanger.

The Difference Between a Chiller and a Cooling Tower | Hunker

The Difference Between a Chiller and a Cooling Tower | Hunker

A condenser can be considered a form of heat exchanger as it is similar to a chiller heat exchanger in function. While a heat exchanger can regulate process temperatures independently, a condenser is a component of a chiller system (water-cooled or air-cooled) which functions to remove heat generated by an industrial or commercial process.

CHILLER PLANT CONTROL

CHILLER PLANT CONTROL

Typically, the condenser system functions as follows: the chiller requests that the condenser pump and cooling tower become active. If the chiller is equipped with an isolation valve, the position of the valve (open/closed) needs to be verified before starting the pump. Once flow has been established, and veri-
