plate fin heat exchanger
Working Principle
The plate heat exchanger has 2 types, the plate total heat exchanger and the plate sensible heat exchanger.The two air flows will flow in opposite directions (counter flow) to further enhance the exchange of heat. The two air flows are isolated by special material which is heat-conducting and moisture-conducting. As far the temperature or moistures is different, heat or moisture will transfer from one side to another. So the energy is recoveried. the working Principle, see fig
Sensible heat recovery exchange the heat through aluminum fins, but total heat recovery exchange the heat through total heat exchanger paper. The fiber gap of total heat exchanger paper is very small, water vapour molecule can pass through it, but the gas molecule of poisonous or peculiar smell cannot pass.
Structure Characters
Sensible heat recovery exchanger uses high-quality coated aluminum foil as the heat-transfer conductor,marine corrosion resistance,high heat-exchange efficency,long life,specially used in large temperatur difference indoor and outdoor,low humidity areas,
Total heat recovery heat exchanger uses imported high-quality enthalpy exchanger paper as heat-transfer and humidity-transfer condutor which has high rate of perviousness,perfect hermetility.specially used in little temperature difference indoor and outdoor,high humidity areas.
Without running compoments,less mainterance cost.
Compact structure,less space occupancy,meet the needs of various situations.

Product Selection
The product would be selected in the range(1.5m/s~3.5m/s) of ecnomical operation air speed as much as possible. That would get good operation effect.
The heat tube energy recovery exchanger has various specifications according to the requirments, see fig.
