Coil or Evaporator was part of air. By the way, we see inside the building. You wonder coil is, do what is the principle works
.Function of the coil is made น้ำยาแอร์ or refrigerant was boiling inside tube The fluid through the outside pipe cooled. The coil like this is called A direct expansion coilIn order to enhance heat transfer Direct expansion coil model available with air conditioning. To control the flow rate of the refrigerant น้ำยาแอร์ or by expansion valve
.But also the cooling coil is another way to make refrigerant flow or nonsense is appealing to coil pressure and low temperature a lot of plenty. The liquid part will boil in coilThe liquid will be excluded. The remaining vapor into the compressor. In the cooling system with very low temperature often use coil like this. Due to the interior surface has the advantages of wet throughout the coil
