Dry-type evaporators are also called direct-expansion evaporators. . Reduces coil depth for the evaporator and condenser, which leads to easier cleaning an less air side static pressure. - Reduced internal volume reduces refrigerant charge . - Reduced face area of condenser and evaporator. - smaller footprint for the condensing unit - A 30% .
Dry expansion evaporators are so called because liquid refrigerant enters the evaporator by an expansion valve and vapourises by the time it reaches the end of the evaporator coil. There is always at least 20% vapour present within the evaporator pipework. The amount of liquid present in dry expansion evaporators will depend upon the fixture load.
Jan 26, 2013· How does evaporator work ? . Evaporator are also classified into flooded type and dry expansion type, depending on whether the refrigerant covers all the surface of heat transfer or some portion of heat transfer surface is having gas being superheated. .

The metering device at work with such way of submission of refrigerant or thermostatic expansion valve (TXV) or capillary tube. To ensure complete evaporation of the refrigerant in the evaporator, the refrigerant in a dry-expansion of the supply system can become overheated. To prevent overheating of the loss of the liquid in the suction line.
Mar 29, 2016· Hello Everybody I am a mechanical engineer from Iran who is working for a company manufacturing different components pertaining to Air-Conditioning and Refrigeration systems. We are in our research department going to design a chiller using a flooded evaporator. As you know flooded evaporators are different from dry expansion ones so that in flooded type we place refrigerant in shell …
Jun 09, 2019· It required more liquid refrigerant than dry type evaporator. With the help of a float chamber, the liquid refrigerant is supplied into the drum of an evaporator. Flooded type evaporator is used for high capacity systems. Dry Expansion Type Evaporator: The rate of heat transfer is less in dry type evaporator compared to flooded type evaporator .
