The role of coils in the refrigeration cycle

The role of coils in the refrigeration cycle

Coils are known as the most important component in air conditioning and refrigeration systems. One of the most important heating and cooling cycles is the refrigeration cycle. Condenser coils, usually located in the outdoor unit of the system, help to dissipate the heat that has been absorbed from the indoor space. These coils operate at high pressure and temperatures and help to convert the refrigerant from gas to liquid. On the other hand, the evaporator coils, which are located inside...

What is Evacuation

Q: What is the purpose for ‘evacuating’ a refrigeration system? Evacuating a refrigeration system serves two primary objectives: 1. Removes non-condensables 2. Dehydrates (removes water vapor) If non-condensables such as air are not removed, the system will operate at higher than normal condensing pressures. This happens because the air is trapped at the top of the condenser, effectively reducing the condenser capacity. Increasing the condensing pressure results in higher compression ratios and higher discharge temperatures, both of which decrease system...
