condenser-water temperature drops, so do refrigerant temperature and pressure. As the refrigerant pressure and temperature changes, the work a compressor must do also changes. The effect of leaving-condenser-water temperature change on power consumption can be 1.0 to 2.2 percent per degree Fahrenheit [1.8 to 4.0 percent per degree Celsius].

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

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.
