How Does an Industrial Chiller Work?

The refrigerant moves through the evaporator, compressor, condenser, and expansion valve during the mechanical compression cycle of a chiller.

The condenser provides two functions during the cycle. It is necessary to first de-superheat the high-pressure refrigerant vapour (brought to a saturated condition). The refrigerant's temperature must be lowered to saturation temperature by transferring enough heat. Afterwards, condensation might begin.

Up until the refrigerant is entirely condensed, the quality of the refrigerant degrades as heat is transferred from the refrigerant vapour to the air (or water in the case of a water condenser). Ideally, this happens at the condenser's outlet, but in reality, some sub-cooling is typical. As the refrigerant loses pressure in the tubing and other components, the sub-cooled liquid prevents liquid flashing.

The refrigerant is a high-pressure, high-temperature liquid at this moment. It still needs to go through one more step before it can be used as a heat transfer medium for cooling: the temperature needs to be decreased. The thermostatic expansion valve performs this function by lowering the pressure, which in turn lowers the temperature.

Since the valve is primarily a superheat control, it cannot maintain constant pressure even though it modulates to aid in doing so. An evaporator pressure regulator valve can be incorporated into the system to maintain constant pressure.

The refrigerant passes through the evaporator tubing in the last stage, where it has transformed into a saturated liquid and vapour mixture. The evaporator is exposed to warm air, which heats the refrigerant as it boils. The refrigerant doesn't become any hotter, but as the liquid boils off and the vapour becomes saturated and ready to start the process again, it does change state. This procedure is repeated by the chiller until the required temperature is reached in the room. Then the machinery turns itself off.
