Centrifugal Chiller. Centrifugal chillers are the most common type of chiller in HVAC. Centrifugal chillers are mostly water-cooled.
A centrifugal chiller utilizes the vapor compression cycle to chill water and reject the heat collected from the chilled water plus the heat from the compressor to a second water loop cooled by a cooling tower. Shows the basic centrifugal refrigeration circuit. It consists of the following four main components;

| Evaporator
The evaporator is a heat exchanger that removes the building heat from the chilled water lowering the water temperature in the process. The heat is used to boil the refrigerant changing it from a liquid to a gas. chillers use a flooded type evaporator, which is very energy efficient. Flooded evaporators have the chilled water in the tubes and the refrigerant in the shell. Large chillers can have over five miles of tubing in their heat exchangers. |
Compressor
The compressor assembly is made up of a prime mover and a centrifugal compressor. McQuay Distinction™ series chillers use liquid refrigerant cooled hermetic electric motors (an industry first). The centrifugal compressor is a non-positive displacement type. It raises the pressure and temperature of the refrigerant by converting kinetic energy into pressure.
Condenser
Like the evaporator, the condenser is a heat exchanger. In this case, it removes heat from the refrigerant causing it to condense from a gas to a liquid. The heat raises the water temperature. The condenser water then carries the heat to the cooling tower where the heat is rejected to atmosphere.
Expansion Device
After the refrigerant condenses to a liquid, it passes through a pressure reducing device. This can be as simple as an orifice plate or as complicated as a electronic modulating thermal expansion valve. McQuay Distinction™ series chillers use a Thermal Expansion Valve to give excellent modulation with a wide range of capacity and temperature conditions.
Pressure-Enthalpy Diagram
The Pressure-Enthalpy (P-H) diagram is another way of looking at the refrigeration cycle. It has the advantage of graphically showing the process, the cooling effect and the work required to make it happen.
