Evaporator

Water-cooled chillers are typically installed indoors; air-cooled chillers are typically installed outdoors—either on the roof or next to the building. In cold climates, air-cooled chillers may have a remote evaporator inside the building for freeze protection.

Chiller evaporator

The evaporator section of a water chiller is a shell-and-tube, refrigerant-to- water heat exchanger. Depending on the chiller’s design, either the refrigerant or the water is contained within the tubes.

•In a flooded shell-and-tube evaporator (Figure 2), cool, liquid refrigerant at low pressure enters the distribution system inside the shell and moves uniformly over the tubes, absorbing heat from warmer water that flows through the tubes.
