Cold coil or Evaporator is a component of the air. Another one that we see inside the building, you wondered what is the evaporator do? There is major work?[/caption]The duties of the evaporator is a refrigerant or coolant boiling occurs inside the pipe and cause a fluid passing through the outer tubes cool down the evaporator, which is called the evaporator direct expansion, which form inside the evaporator will have installed pipe heat sinks. To enhance heat transfer Evaporator direct expansion model with air conditioning system controls the flow of refrigerant or refrigerant by the expansion valve, so that the refrigerant leaving the evaporator is an ultra hot.But there is also one evaporator which makes the liquid refrigerant flow or is absorbed into the evaporator pressure and temperature, low bulk, allowing. The liquid boils, some of which went in, but still wet and flooded evaporator is located at the mouth of the exit. As part of the separated liquids remain only as vapor into the compressor. In the cooling system at very low temperature refrigerated coils are often used because there are advantages with wet surface throughout the evaporator and heat transfer efficiency higher.
