(4) for heating and moistening process in winter, the return air temperature of this system is higher, therefore evaporating temperature is high, and system COP is higher.
Accompanying drawing explanation
Fig. 1 is the theory structure schematic diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See Fig. 1, the present embodiment comprises heat pump, and heat pump comprises compressor 1, cross valve 2, First Heat Exchanger 3, second heat exchanger 4; It also comprises VMC; Described VMC comprises and is connected to return air duct 10 on First Heat Exchanger 3 and exhaust duct 11, be connected to the air supply duct 12 on the second heat exchanger 4 and outdoor fresh air pipeline 13, First Heat Exchanger 3 is connected with air supply duct 12 and outdoor fresh air pipeline 13 by ventilation shaft, and the second heat exchanger 4 is connected with return air duct 10 and exhaust duct 11 by ventilation shaft; The first blower fan 14 and the second blower fan 9 is respectively arranged with at the air outlet of exhaust duct 11 and air supply duct 12; Return air duct 10 and the connector place of First Heat Exchanger 3 are provided with the first air-valve 8, the connector place of return air duct 10 and the second heat exchanger 4 is provided with the second air-valve 7, the connector place of outdoor fresh air pipeline 13 and the second heat exchanger 4 is provided with the 3rd air-valve 6, at outdoor fresh air pipeline 13, the connector place of First Heat Exchanger 3 is provided with the 4th air-valve 5; First Heat Exchanger 3 and the second heat exchanger 4 are attached with hygroscopic materials.
Under cooling in summer operating mode, carrying out practically process of the present utility model is as follows:
See Fig. 1, under cooling in summer operating mode, this air conditioning system is identical with the operating condition of traditional air conditioner VMC, and now the second heat exchanger 4 is evaporimeter, and First Heat Exchanger 3 is condenser.3rd air-valve 6, first air-valve 8 is opened, and the 4th air-valve 5, second air-valve 7 cuts out.Outdoor new wind is direct through the second heat exchanger 4 by the 3rd air-valve 6, steam in new wind absorb by the hygroscopic materials on the second heat exchanger 4 surface, simultaneously when the second heat exchanger 4, new air temperature reduces, send into indoor by the second blower fan 9, thus reach effect outdoor air being carried out to cool-down dehumidification.Now, return air is drained in outdoor environment by the first air-valve 8 and the first blower fan 14.In dehumidification process, the steam partial pressure on hygroscopic materials surface increases gradually, until identical with the new geomantic omen vapor pressure entered in heat exchanger time, the regeneration of hygroscopic materials wettability power need be completed.Now, cross valve 2 switches, and the second heat exchanger 4 is condenser, and First Heat Exchanger 3 is evaporimeter.3rd air-valve the 6, the 1 cuts out, and the 4th air-valve the 5, the 27 is opened.New wind is indoor by sending into after the 4th air-valve 5, First Heat Exchanger 3 cool-down dehumidification.And the cold-producing medium of heat flows into condenser, add the steam partial pressure on hygroscopic materials surface, make it higher than the steam partial pressure in return air, the steam on the second heat exchanger 4 surface drains in outdoor environment by return air, thus its wettability power is regenerated.
In the winter time under heating condition, carrying out practically process of the present utility model is as follows:
See Fig. 1, in the winter time under heating condition, heat the initial stage, without the need to carrying out humidification to room air, First Heat Exchanger 3 is evaporimeter, and the second heat exchanger 4 is condenser.3rd air-valve the 6, the 1 is opened, and the 4th air-valve the 5, the 27 cuts out, and send into indoor after outdoor new wind is heated up by the 3rd air-valve 6 and the second heat exchanger 4, return air is discharged to outdoor environment by the first air-valve 8, First Heat Exchanger 3.Return air is when through First Heat Exchanger 3, moisture in return air absorb by the hygroscopic materials on First Heat Exchanger 3 surface, when the steam partial pressure on First Heat Exchanger 3 surface is equal with the steam partial pressure in return air, cross valve 2 switches, First Heat Exchanger 3 is condenser, and the second heat exchanger 4 is evaporimeter.Now, the 4th air-valve the 5, the 27 is opened, and the 3rd air-valve the 6, the 1 cuts out.Bring the moisture of condenser surface into indoor when new wind enters First Heat Exchanger 3 by the 4th air-valve 5, improve the temperature of new wind simultaneously, achieve the heating and moistening to new wind.In humidification, the steam partial pressure on First Heat Exchanger 3 surface reduces gradually, until and new wind in steam partial pressure equal time, cross valve 2 switches, and now, First Heat Exchanger 3 is evaporimeter, and the second heat exchanger 4 is condenser.This system repeat the initial stage that heats do not give indoor humidification time heat circulation, complete the regeneration of its humidification capability.
In cooling in summer dehumidification process, because air is without the need to reaching dew-point temperature, evaporating temperature is higher, and system return air temperature is lower, and condensation temperature is low, therefore COP is higher; In the winter time in heating and moistening process, system return air temperature is higher, therefore evaporating temperature is high, and system COP is higher.This system, compared with traditional air conditioner VMC, has the function of humidification, dehumidifying voluntarily, and without the need to setting up humidification/dehumidification equipment and water source, system architecture is simple, and comparatively traditional air conditioner VMC is high for COP.
