The air-cooled condensers find applications in domestic, commercial, and industrial refrigerating, chilling, freezing, and air conditioning systems with a common capacity of 20—120 tons (Figure…

Water-cooled condensers are of many different types as shown in Figure 3.17. The most common condensers are generally shell and tube type heat exchangers with…
There are several condensers to be considered when making a selection for installation. They are air-cooled, water-cooled, shell and tube, shell and coil, tube within…
A capacity controlled refrigeration unit is a unit in which the compression ability of the compressor can be controlled to reduce or increase refrigerant mass…
In practice ARI Standard 500-2000 defines the compressor efficiency as the ratio of isentropic work to the actual measured input power. Therefore, the compressor efficiency…
The compression ratio is defined as the ratio of discharge pressure to suction pressure at saturated conditions, expressed in absolute terms, e.g. Pa or kPa.…
In refrigeration technology, turbo compressors usually denote centrifugal compressors, but their efficiencies are low. In this type of compressor, the discharge pressure is limited by…
Centrifugal compressors are often used in place of positive displacement compressors for very large capacities, or for high-flow low-pressure difference applications, and are available, designed…
The scroll compressor (Figure 3.12) uses one stationary (fixed) and one orbiting scroll to compress refrigerant gas vapors from the evaporator to the condenser of…
Surprisingly enough, the screw compressor was invented in 1878. However, commercial application developed slowly because of its inability to match tight tolerances with existing manufacturing…
