Copper Tube Evaporator Water - Cooled Type
Shell and Tube Heat Exchanger
The difference between shell and tube condenser and evaporator:
1, the heat transfer tube is not the same (condenser, evaporation tube).
2, the working temperature is not the same (35 ℃, generally below 5 ℃ below).
3, the heat transfer form is not the same (bead condensation, nuclear boiling).
4, the work pressure is not the same (high pressure 10bar above, low pressure 3bar below).
5, the internal structure is not the same (tube cooling water, tube outside the steam, tube cold water pipe
outside the tube or pipe refrigerant outside the chilled water)
1, the central air-conditioning condenser, evaporator and compressor in the outdoors, water and return
pipe is the same, are generally 100 of the tube, which is installed water [that is, refrigerant is water],
indoor machine, Two 25 or 32 pipe connected, one is the inlet pipe, one is the outlet pipe. There is also a
small tube is a drain.
Winter tube inside the water temperature temperature of 70 degrees or so, through the indoor evaporator
to the temperature blowing to the room, the opposite of summer!
2, the central air conditioning is generally used as a refrigerant to transport the cold medium, refrigerant
water in the evaporator evaporator with the refrigerant heat exchange, to the refrigerant heat release,
through the pump and pipeline to a variety of air conditioning processing device In the heat with the air
after being treated, the refrigerant water through the return pipe back to the evaporator evaporator, so
the cycle!
3, the compressor to the condenser into the high temperature and high pressure superheated steam,
steam in the condenser to the ambient medium [air or water] heat, cooling into high pressure superheated
liquid, through the throttle decompression throat, with saturated steam State into the evaporator
gasification, heat absorption of refrigerant water, and then into a low temperature and low pressure
saturated steam, the compressor suck back, the cycle.
