Describe in detail below according to the work of temperature adjusting and dehumidifying system of the present invention.
The known ground of described above and those skilled in the art, indoor humid air is under the effect of indoor fan 6, successively by indoor evaporator 8 and indoor condenser 7, when humid air passes through indoor evaporator 8, air themperature declines, airborne moisture is in indoor evaporator 8 surface condensations, temperature and the water capacity of air are all reduced, reclaim again all or part of or recovering condensing heat not completely when the indoor condenser 7, the be condensed cold-producing medium heating (temperature-resistant in the time not reclaiming) of high temperature in device of air.
And for refrigeration cycle, in the time that outdoor electric expansion valve 3 is closed completely, whole condensation heat is all born by indoor condenser 7, condensation heat is reclaimed by indoor condenser 7 completely, adds heat maximum, and for example wind pushing temperature can reach 45 DEG C; And in the time that indoor electronic expansion valve 4 cuts out completely, whole condensation heat is all born by outdoor condenser 2, condensation heat is all dispersed into outdoor (not having condensation heat to be recovered), adds heat minimum, and for example wind pushing temperature can reach 12 DEG C.When outdoor electric expansion valve 3 and indoor electronic expansion valve 4 all partially open, can regulate continuously the aperture of two electric expansion valves, to regulate the condensation heat being recovered, and then the wind pushing temperature of regulating system, realize wind pushing temperature and within the scope of 12 DEG C～45 DEG C, regulate continuously and stably or control.Preferably, the control method of two electric expansion valves is as follows: the air of the aperture of indoor electronic expansion valve 4 based on measuring controlled or regulate that (preferred controlled unit is controlled automatically from indoor condenser 7 temperature (wind pushing temperature) out, but do not get rid of the aperture of electric expansion valve 4 in the information conditioning chamber that operator provides by wind pushing temperature sensor yet), and the suction superheat that the aperture of outdoor electronic expansion 3 is the compressors 1 based on measuring is controlled or regulates.When actual wind pushing temperature higher than set wind pushing temperature (for example wind pushing temperature threshold values) time, reduce the aperture of indoor electronic expansion valve 4, reduce through the refrigerant flow of indoor condenser 7, the condensation heat that air reclaims also reduces, and the outlet temperature of air reduces; Otherwise, when actual wind pushing temperature lower than set wind pushing temperature time, the aperture of indoor electronic expansion valve 4 increases, and increases through the refrigerant flow of indoor condenser 7, the condensation heat that air reclaims also increases, the outlet temperature of air rises.Can realize good temperature by the arranged in series of indoor condenser and indoor electronic expansion valve regulates, and because this electric expansion valve is not arranged in the closed circuit of series connection, thereby the impact of the especially outdoor condenser of other parts on system drops to minimum.Owing to including but not limited to the many factors such as the variation of wind pushing temperature, air quantity or the adjusting of indoor electronic expansion valve 4, the running status of kind of refrigeration cycle also changes in running, thereby the suction superheat of compressor 1 may increase or reduce in running.And the excessive indoor evaporator 8 inner refrigerant liquid contents that make of the degree of superheat reduce, the refrigeration of system and dehumidifying effect all can decline, and the operational efficiency of system also declines; And the degree of superheat is too little, liquid refrigerant can not be evaporated completely in indoor evaporator 8, and liquid refrigerant enters compressor 1 can cause the liquid hammer of compressor 1, easily causes the damage of compressor 1.Therefore, in temperature adjusting and dehumidifying system according to the present invention, the suction superheat of compressor 1 based on measuring regulates or the aperture of control room exoelectron expansion valve 3, from and change the current suction superheat of compressor so that it falls into suitable scope or arrives suitable numerical value.For example, when actual suction superheat higher than set the degree of superheat (for example degree of superheat threshold values) time, the aperture of outdoor electric expansion valve 3 increases, the liquid refrigerant that flows into indoor evaporator 8 increases, the degree of superheat declines; Otherwise, when actual suction superheat lower than set the degree of superheat time, the aperture of outdoor electric expansion valve 3 reduces, flow into indoor evaporator 8 liquid refrigerant reduce, the degree of superheat rise.As stated in the Background Art, adjustable throttling arrangement in CN200610088389.5 and CN20133158Y all can not be realized in the time of temperature adjusting and dehumidifying the refrigerant flow of indoor and outdoors condenser is carried out to control independent of each other, regulate any adjustable throttling arrangement to have impact to the refrigerant flow of indoor and outdoors condenser, this for example can cause the poor and/or shortcoming such as system complex and/or reliability relative mistake of thermoregulation effect; And CN98215431.3 not can control the flow of outdoor condenser.By this make of the present invention, the control that can find the flow of described electric expansion valve to indoor and outdoors condenser is independent of each other, thereby for example bring in the situation that having ensured thermoregulation effect, also effectively increase the reliability of this temperature adjusting and dehumidifying system the advantage that has extended the life-span, and also there is easy realization simple in structure.It will be appreciated by one of skill in the art that adjusting or control to indoor and outdoors condenser are independently, be only just regulate or control behavior itself, while regulating the indoor electronic expansion valve corresponding to indoor condenser, can not affect the flow of (or can significantly not affect) outdoor condenser, vice versa, and do not get rid of described electric expansion valve adjusting based on parameter between be independent or not associated (for example, as described above, between wind pushing temperature and the degree of superheat, be to exist associated or functional relation).
By the structure of temperature adjusting and dehumidifying system of the present invention, can meet the requirement of cooling and heating load wide variation, in dehumidifying, can regulate continuously wind pushing temperature, make wind pushing temperature regulation and control continuously and reposefully within the scope of 12 DEG C～45C, and there is higher temperature-controlled precision.
