Based on above-mentioned consideration, the present invention takes following technical scheme: be included in the unit of respectively performing the operation distributing purification air-conditioning machine is set, it is characterized in that: outdoor new wind is delivered to respectively perform the operation unit with the brand-new wind of malleation by fresh wind tube through low energy consumption stand alone type purification air-conditioning unit, simultaneously the contaminated air of each operation unit is drawn and successively the exhausting duct by the free-standing purification air-conditioning unit of low energy consumption and Air-Cooled Heat Pump Unit condenser or evaporimeter, the outdoor new wind cooling in summer that enters low energy consumption stand alone type purification air-conditioning unit is heated up winter, because reclaiming through primary energy, air draft enters air-cooled condenser or evaporimeter again simultaneously, further improve its heat exchange efficiency, drain into atmosphere after contaminated air recovers energy.
The air cleaning and conditioning system that the present invention adopts is as follows: the low energy consumption stand alone type purification air-conditioning unit that includes outdoor fresh flue and exhausting duct, Air-Cooled Heat Pump Unit, a plurality of and each distributing purification air-conditioning machine of being complementary of operation unit etc., it is characterized in that: the new wind outlet of low energy consumption stand alone type purification air-conditioning unit is by the air-supply pipeline connection unit of respectively performing the operation, the air draft pipeline that each unit of performing the operation is communicated with connects exhausting duct and the Air-Cooled Heat Pump Unit condenser or the evaporimeter of low energy consumption stand alone type purification air-conditioning unit, and exhaust outlet is positioned at outdoor.
Advantage of the present invention is: 1, designed each operating room scientifically and rationally and disperseed air-conditioning unit and forced draft combined system independently, the forced draft system send fresh air entirely, air is dyed in full blowdown, strict control is infected, simultaneously owing to adopt each operating room to disperse the Air-Cooled Heat Pump Unit of air conditioner and concentrated Cooling and Heat Source, both avoided the cross-infection of air between each operating room, make again this dispersion air-conditioning unit with independently forced draft combined system form operation energy consumption is lower.2, especially make full use of out the temperature difference of air, strengthen air draft evaporation heat absorption, make the higher outdoor new wind of the temperature that enters the part heat be passed to air draft, reduced wind pushing temperature in energy-conservation mode by the form of the latent heat of vaporization in summer.Pass to the new wind that enters from outdoor by the big temperature difference of indoor and outdoor with indoor heat same winter, improves wind pushing temperature in energy-conservation mode, reduced the outside heat extraction of system simultaneously, more meets the environment protection emission requirement.3, realized small investment, operating cost is low, satisfies the function of use requirement.
