Water to Water Tube Heat Exchanger
Water - Cooled Evaporator
Condenser and evaporator in the structure can be exactly the same, to see where the use of the.
Generally in the unit cooling, the refrigerant evaporates inside, that is, evaporator, refrigerant
condensation in the inside, called the condenser.
In the case of the same heat transfer medium, the condenser of a single chiller is generally larger than the
evaporator and the heat transfer area ratio is about 5.5: 4.5.
Because the condenser but also a scattered energy into the heat.
The two are roughly speaking, there is no difference, are the heat exchanger, but the use of different
purposes, the condenser used to discharge heat, the evaporator used to absorb heat.
Carefully speaking, there are differences:
In the condenser design, should be sub-channel, different road entrance should be as close as possible,
exports should also be as close as possible, imports and exports should also be as far as possible to
avoid due to heat loss and loss of part of the heat transfer to avoid uneven distribution of traffic The In the
actual design, if the split more than two, should be used centralized dispenser and collectors, as far as
possible between the different flow of uniform flow. The piping of the different flow paths is preferably the
same, and should flow evenly across the windward side and the leeward side so that the heat transfer is
uniform.
For the evaporator, the requirements are similar, relatively speaking, can be simple, the most common is
the liquid into the liquid part of the split head, divided into more road, and the liquid head must be installed
vertically. The condenser is not split head, the use of sub-gas header.
