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…
Cooling towers (Figure 3.19b) are like evaporative condensers, working on the principle of cooling by evaporating water into a moving air stream. The effectiveness of…
Evaporative condensers are apparently water-cooled designs and work on the principle of cooling by evaporating water into a moving air stream. The effectiveness of this…
