another circuit of water (water-cooled). If the compressor-motor is refrigerant cooled, the chiller also rejects heat generated by motor inefficiency. Air-cooled condensers use fans to facilitate cooling by the ambient air. Water-cooled condensers typically use an evaporative cooling tower. After the water has been chilled, it is distributed ...

www.tranebelgium.comrefrigerant condensing temperature (and pressure) in a water-cooled chiller can be lower than in an air-cooled chiller. For example, at an outdoor design condition of 95°F [35°C] dry-bulb temperature, 78°F [25.6°C] wet-bulb temperature, a cooling tower delivers 85°F [29.4°C] water to the water-cooled condenser.

Similarly, other types of compressors also rely on oil for lubrication and for providing a seal when compressing the refrigerant vapor. Characteristically, some of this lubricating oil is pumped along with the refrigerant throughout the rest of the system.

Absorption Water Chillers
www.tranebelgium.comWater chillers using the vapor-compression refrigeration cycle vary by the type of compressor used. The compressor works to draw in refrigerant vapor and increase its pressure and temperature to create the cooling effect. Reciprocating, scroll, helical-rotary (or screw), or centrifugal compressors are
Centrifugal Water Chillers
www.tranebelgium.comchillers. As mentioned earlier, this particular clinic discusses centrifugal water chillers. Centrifugal water chillers can also be divided into two types based on the method used to reject heat to the atmo sphere: water-cooled or air-cooled. Since most centrifugal chillers are water-cool ed, they are the primary focus of this clinic.
