The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
The multi-functional economic environment-friendly type Novel wind-dehumidifier group of one as shown in Figure 2 and Figure 4, comprised body 1, filter 3, plate-fin sensible heat exchanger 2, centrifugal blower 4 and wind-cooled evaporator 5; And by microcomputer system control operation, operation is very easy.Described plate-fin sensible heat exchanger 2 is arranged in body 1, and body 1 is divided into independent the first chamber 11, the second chamber 12, the 3rd chamber 13 and the 4th chamber 14, wherein the second chamber 12 is communicated with the 3rd chamber 13, this plate-fin sensible heat exchanger 2 is provided with a precooling passage 21 that is communicated with the first chamber 11 and the second chamber 12 is communicated with the 3rd chamber 13 and the 4th chamber 14 preheating channel 22 with one, this structure connects without refrigerant pipe, compact conformation; Described filter 3, centrifugal blower 4 and wind-cooled evaporator 5 are arranged on respectively in the first chamber 11, the second chamber 12 and the 4th chamber 14, and its middle filtrator 3 is arranged on the air inlet of the first chamber 11 and the air outlet of the 4th chamber 14 with centrifugal blower 4,
Its operation principle is as Fig. 3: outdoor new wind enters in the first chamber 11 through filter 3 purified treatment (primarily efficient filter+medium air filtration) under the traction of centrifugal blower, the interior dehumidifying of precooling passage 21 by plate-fin sensible heat exchanger 2 discharged to the second chamber 12 through blower fan water conservancy diversion of pretreated new wind, after the cooling and dehumidifying in wind-cooled evaporator 5 discharged to the 3rd chamber 13, interior by fresh air preheating (air cooling-down with stylish wind after by precooling) through the preheating channel 22 of plate-fin sensible heat exchanger 2 again, described the second chamber 12 is communicated with the 4th chamber 14, in described the 4th chamber 14, be provided with one by the second chamber 12 the electrodeless air-valve 6 to the 4th chamber 14 air drafts.The airborne portion of air of saturated low temperature and low humidity of passing through is now introduced in the 4th chamber and is mixed with the new wind being preheated by the electrodeless adjusting of electrodeless air-valve 6, reach the air-out dry-bulb temperature of demand, become relative humidity higher, the air that water capacity is less is sent into room.By electrodeless air-valve 6, regulate that temperature is very convenient, control accuracy is high, the fire end in is compared to existing technology steam, heat pipe etc., and structure is simpler, and cost is low.Air after outdoor new wind and evaporative cooling being carried out to Exchange of apparent heat, by the cooled air energy of wind-cooled evaporator, process new wind, is new wind cooling and dehumidification, and the new wind after cooling and dehumidification carries out reducing temperature twice dehumidifying by wind-cooled evaporator simultaneously.Thereby improved the heat exchange efficiency of wind-cooled evaporator 5, effectively must reduce the energy consumption of processing new wind in wet unit, therefore made the operating cost of dehumidifier greatly reduce.
Dehumidifying situation analysis:
1. in air, humidity is not large especially, dehumidifying: new rheumatism air is through plate-fin sensible heat exchanger 2, relative air humidity is increased, water capacity reduces, now air reaches capacity, and now saturated air is mainly latent heat exchange through wind-cooled evaporator 5 heat exchange, air themperature infinite approach dew point, greatly increase the heat exchange efficiency of wind-cooled evaporator 5, unit entirety energy consumption reduces greatly.
2. in air, humidity is very large, dehumidifying: new wind highly humid air is through plate-fin sensible heat exchanger 2, air is dehumidified, relative humidity increases, and water capacity reduces, but air also reaches capacity far away, now air is through wind-cooled evaporator 5 dehumidifying and cooling again, air is approached saturated, greatly increase the heat exchange efficiency of wind-cooled evaporator 5, unit entirety energy consumption reduces greatly.
The advantages of this design is high in wind-cooled evaporator 5 efficiency, wind-cooled evaporator 5 can be done littlely under the prerequisite that meets system needs, greatly reduces heat exchanger cost.
Because outdoor new wind is generally 35 ° of left and right, and the optimum working temperature of wind-cooled evaporator is 27 °, so new wind is by 2 precoolings of plate-fin sensible heat exchanger, arrive again wind-cooled evaporator precooling dehumidifying, finally again by passing through 2 preheatings of plate-fin sensible heat exchanger, by plate-fin sensible heat exchanger 2, replaced the function (design originally first will cool to 27 ° of left and right by cooling water pipe comb by new wind before wind-cooled evaporator cooling) of cooling water pipe comb, thereby structure is simpler, energy consumption and parts expense have been saved.And plate-fin sensible heat exchanger 2 of the present invention is that outdoor high temperature and the wind after wind-cooled evaporator cooling are directly exchanged, so that the efficiency of plate-fin sensible heat exchanger 2 is high, so heat transfer effect is strong, (after being discharged to indoor air return air, temperature can be too not high yet, normal than the high 5 ° of left and right of cooled new air temperature, pass through again sensible heat exchanger heat exchange, so heat transfer effect is not high)
As shown in figures 1 and 3, dehumidifying unit of the present invention also comprises host side 7, and described host side 7 comprises compressor, air-cooled condenser, expansion valve, four-way change-over valve, gas-liquid separator and condensing axial flow fan; Described compressor, gas-liquid separator are connected with four-way change-over valve, and described four-way change-over valve, air-cooled condenser, expansion valve wind-cooled evaporator 5 are connected.Wherein said air-cooled condenser is provided with the condensing axial flow fan of cooperation.This structure can make dehumidifying unit of the present invention use as the heat pump machine that can freeze and heat, and realizes the multi-functional of product.Its workflow:
Cooling flow: compressor-four-way change-over valve-air-cooled condenser-expansion valve-wind-cooled evaporator-four-way change-over valve-gas-liquid separator-compressor;
Heat flow process: compressor-four-way change-over valve-wind-cooled evaporator-expansion valve-air-cooled condenser-four-way change-over valve-gas-liquid separator-compressor.
It should be noted that when economic environment-friendly type Novel wind-dehumidifier group is used as novel wind-heat pump assembly, electrodeless air-valve 6 standard-sized sheets, outdoor new wind is centrifuged blower fan 4 tractions through filter 3 and plate-fin sensible heat exchanger 2, through wind-cooled evaporator 5, will meet the requirements of cold air or hot-air and by electrodeless air-valve 6, be centrifuged blower fan and send into room, now sensible heat exchanger is because air drag does not participate in heat exchange.
And transition season, desired wind pushing temperature and ambient temperature are more or less the same, do not open compressor, only open centrifugal blower 4, electrodeless air-valve 6, outdoor new wind is centrifuged blower fan 4 tractions through filter 3, plate-fin sensible heat exchanger 2, wind-cooled evaporator 5, and electrodeless air-valve 6, sends air into room.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
