Similarly, what is the evaporator in air conditioner? Stainless Steel Evaporator; Unit Cooler; Cooler. The refrigerant has a temperature of -10 C at the inlet of the heat exchanger. (Many people end up replacing their systems between 12 and. The refrigerant leaves the evaporator in vapor state, mostly superheated and is absorbed by the compressor. They are also classified in different manner depending on the method of feeding the refrigerant, construction of the evaporator, direction of air circulation around the evaporator, application and also the refrigerant control. The evaporators are classified based on the construction as: The bare tube evaporators are the simple copper coil evaporators over which the substance to be cooled flows. The refrigerant is let into and measured by a flow control device, and eventually released to the compressor. The plate surface evaporators are commonly used in the household refrigerators. The four major components of the refrigeration system are compressor, evaporator, condenser and throttling device. After the Some signs to look out for include: Warm air blowing through the air vents. In case of the flooded the evaporator is filled with the refrigerant and constant level of the refrigerant is maintained inside it. One specific example of this is NT applications involving the refrigeration of unpackaged foodstuffs that are susceptible to humidity. In case of large refrigeration plants and central air conditioning plants the evaporator is also known as the chiller since these systems are first used to chill the water, which then produces the cooling effect. In such plants the evaporators or the chillers are classified as: In case of the dry expansion type of chillers or evaporators the flow of the refrigerant to the evaporators is controlled by the expansion valve. Category. It acts as a heat exchanger that transfers heat from the substance being cooled to a … These evaporators are also in the form of coil which is attached to the plate.
