Some of the refrigeration units have enough space within the condenser to accommodate the entire refrigerant charge of the system. If the condenser does not…

It is well known that compressors are designed to compress vapors, not liquids. Many refrigeration systems are subject to the return of excessive quantities of…
The capillary tube is the simplest type of refrigerant flow control device and may be used in place of an expansion valve. The capillary tubes…
These valves are divided into high-side float valves and low-side float valves. They are employed to control the refrigerant flow to a flooded-type liquid cooler.…
The constant pressure valve is the forerunner of the thermostatic expansion valve. It is called an automatic expansion valve due to the fact that it…
The thermostatic expansion valves are essentially reducing valves between the highpressure side and the low-pressure side of the system. These valves, which are the most…
In practice, throttling devices, called either expansion valves or throttling valves, are used to reduce the refrigerant condensing pressure (high pressure) to the evaporating pressure…
These coolers are generally called direct expansion coils and consist of a series of tubes through which refrigerant flows (Figure 3.21). The tubes, which are…
Shell and tube type heat exchangers (Figure 3.20) are the more common form of evaporation units for water cooling and chilling applications. These are utilized…
Evaporator can be considered the point of heat capture in a refrigeration system and provides the cooling effect required for any particular application. There are…
