Mini channel Heat Exchanger, Micro channel Heat Exchanger, Liquid desiccant, Airconditioning, Heat transfer, Compact SystemAbstract
Micro-channel and Mini channel heat exchangers are being used in air conditioning applications
due to its favorable characteristics like higher heat and mass transfer, compact system and lower cost etc. In
this review paper, characteristics of air conditioning system with mini channel and micro channel heat
exchangers are analyzed. Mini-channel and micro-channel heat exchangers have higher surface contact
area to volume ratio. Mini channel and micro-channel heat exchangers are lighter in weight because they
are made of aluminum only. Also the cost of mini channel heat exchanger is less because of aluminum
structure. Mini channel uses less power and refrigerant charge so it is also good for environment.
Effectiveness of mini channel heat exchanger is increased by using fin at internal and external both the side.
Mini-channel heat exchanger and micro-channel heat exchanger can be used in refrigeration and air
conditioning system. In air conditioning system at both mini channel and micro-channel heat exchanger can
be applied as both the condenser and evaporator. In Mini-channel and micro-channel heat exchanger the
sensible and latent both cooling capacity increases and overall efficiency of air conditioning system
increases.
