Description of drawings
Fig. 1 is the heat recovery fresh air dehumidifier system schematic of the embodiment of the invention one;
Fig. 2 is the heat recovery fresh air dehumidifier structural representation of the embodiment of the invention two.
The specific embodiment
Embodiment one, sees also Fig. 1, and the present invention is a kind of heat recovery fresh air dehumidifier that carries Cooling and Heat Source, and unit adopts the levels structure, comprises four major parts: fresh air dehumidifying system, return air heat recovery system, secondary fresh air system, refrigeration system.
Fresh air dehumidifying system is positioned at unit lower floor, comprises the first fresh wind port A, surface cooler 3, evaporimeter 5, is positioned at drip tray 4, the second condenser 7, pressure fan 8 and the air outlet B of surface cooler 3 and evaporimeter 5 belows.The first new wind A of outdoor high temperature high humidity enters from a side, at first pass through surface cooler 3, by cool-down dehumidification, the new wind A of first after the precooling is through the further cool-down dehumidification of evaporimeter 5 quilts, be heated to the air-supply point through the second condenser 7 again, send into indoor finally by pressure fan 8, air outlet B.Surface cooler 3 connects (7～12 ℃) chilled water, for the air-conditioning system Energy Efficiency Ratio is provided, also can connect the chilled water (12～16 ℃) of other air-conditioner after out, perhaps directly connects the cold water (16～18 ℃) of high temperature cold water unit.
