Can also comprise according to temperature adjusting and dehumidifying of the present invention system and to be used for automatically regulating the aperture of said indoor throttling arrangement and automatically regulating the control module (not shown) of the aperture of said outdoor throttling arrangement based on the degree of superheat of measuring based on the air themperature of measuring (or its functional value, mean value or approximation).Preferably; Compressor 1 is ability speed variable or variable exhaust displacement compressor; Through the rotating speed of adjusting compressor or the refrigeration and the dehumidifying effect of delivery space adjustable systems, and this control module can change the rotating speed or the delivery space of compressor based on the cold-producing medium evaporating temperature that said evaporating temperature sensor 9 records.Preferably, this temperature adjusting and dehumidifying system can have the threshold values corresponding to above-mentioned relevant parameter.For example this temperature adjusting and dehumidifying system can comprise wind pushing temperature threshold values, degree of superheat threshold values and/or evaporating temperature threshold values.It may occur to persons skilled in the art that these threshold values can make fixed value, numerical value is interval and/or for example time dependent function, and these threshold values preferably can be by the parameter change that the operator regulates and control is perhaps sensed based on other induction installation.Control module can be through controlling (the for example aperture of electric expansion valve) with parameter of measuring and the corresponding component that corresponding threshold values is relatively recently exchanged warm dehumidification system.
Describe work below in detail according to temperature adjusting and dehumidifying of the present invention system.
As stated and the known ground of those skilled in the art; Indoor humid air is under the effect of indoor fan 6, and successively through indoor evaporator 8 and indoor condenser 7, air themperature descended when humid air passed through indoor evaporator 8; Airborne moisture is in indoor evaporator 8 surface condensations; The temperature and the water capacity of air all are reduced, and reclaim all or part of during again through indoor condenser 7 or do not reclaim condensation heat fully, the be condensed cold-producing medium heating (temperature-resistant when not reclaiming) of high temperature in the device of air.
And for refrigeration cycle, when outdoor electric expansion valve 3 was closed fully, whole condensation heat was all born by indoor condenser 7, and condensation heat is reclaimed by indoor condenser 7 fully, adds the heat maximum, and for example wind pushing temperature can reach 45 ℃; And when indoor electric expansion valve 4 was closed fully, whole condensation heat was all born by outdoor condenser 2, and condensation heat all is dispersed into outdoor (not having condensation heat to be recovered), adds the heat minimum, and for example wind pushing temperature can reach 12 ℃.When outdoor electric expansion valve 3 all partially opens with indoor electric expansion valve 4; Can regulate the aperture of two electric expansion valves continuously; The condensation heat that is recovered with adjusting, and then the wind pushing temperature of regulating system realize that wind pushing temperature regulates or control continuously and stably in 12 ℃~45 ℃ scopes.Preferably; Two electronic Expansion Valve Control methods are following: the temperature (wind pushing temperature) that the aperture of indoor electric expansion valve 4 is come out from indoor condenser 7 based on the air of measuring is come by control or is regulated and (preferably controlled automatically by the control unit; But the aperture of also not getting rid of electric expansion valve 4 in the information conditioning chamber that the operator provides through wind pushing temperature sensor), controlled or regulated and the aperture of outdoor electronic expansion 3 is based on the suction superheat of the compressor 1 of mensuration.When the wind pushing temperature of reality is higher than the wind pushing temperature (for example wind pushing temperature threshold values) of setting, reduce the aperture of indoor electric expansion valve 4, then the refrigerant flow through indoor condenser 7 reduces, and the condensation heat that air reclaims also reduces, and the outlet temperature of air reduces; Otherwise when the wind pushing temperature of reality was lower than the wind pushing temperature of setting, the aperture of indoor electric expansion valve 4 increased, and then the refrigerant flow through indoor condenser 7 increases, and the condensation heat that air reclaims also increases, and the outlet temperature of air rises.Arranged in series through indoor condenser and indoor electric expansion valve can realize good adjustment; And since this electric expansion valve be not arranged in the closed circuit of series connection, thereby drop to minimum to the influence of the especially outdoor condenser of other parts of system.Owing to include but not limited to the variation of wind pushing temperature, air quantity or the multiple factors such as adjusting of indoor electric expansion valve 4; The running status of kind of refrigeration cycle also changes in running, thereby the suction superheat of compressor 1 possibly increase or reduce in running.And the excessive indoor evaporator 8 inner refrigerant liquid contents that make of the degree of superheat reduce, and the refrigeration of system and dehumidifying effect all can descend, and the operational efficiency of system also descends; And the degree of superheat is too little, and liquid refrigerant can not be evaporated in indoor evaporator 8 fully, and liquid refrigerant gets into the liquid hammer that compressor 1 can cause compressor 1, is prone to cause the damage of compressor 1.Therefore; In temperature adjusting and dehumidifying according to the present invention system; Regulate or the aperture of control room exoelectron expansion valve 3 based on the suction superheat of the compressor of measuring 1, from and change the current suction superheat of compressor so that it falls into suitable scope or arrives suitable numerical value.For example, when the suction superheat of reality was higher than the degree of superheat (for example degree of superheat threshold values) of setting, the aperture of outdoor electric expansion valve 3 increased, and the liquid refrigerant that then flows into indoor evaporator 8 increases, and the degree of superheat descends; Otherwise when the suction superheat of reality was lower than the degree of superheat of setting, the aperture of outdoor electric expansion valve 3 reduced, and the liquid refrigerant that flows into indoor evaporator 8 reduces, and the degree of superheat rises.Of background technology; Refrigerant flow to the indoor and outdoors condenser when scalable throttling arrangement among CN200610088389.5 and the CN20133158Y all can not be implemented in temperature adjusting and dehumidifying carries out control independent of each other; It is all influential to the refrigerant flow of indoor and outdoors condenser promptly to regulate any scalable throttling arrangement, and this for example can cause shortcomings such as thermoregulation effect difference and/or system complex and/or reliability relative mistake; And CN98215431.3 not can control the flow of outdoor condenser.Through this make of the present invention; Can find that said electric expansion valve is independent of each other to the control of the flow of indoor and outdoors condenser; Thereby for example brought under the situation that has guaranteed thermoregulation effect; Also increase the reliability of this temperature adjusting and dehumidifying system and the advantage that has prolonged the life-span effectively, and also had the advantage of easy realization simple in structure.It will be appreciated by one of skill in the art that adjusting or control to the indoor and outdoors condenser are independently; Only be just regulate or the control behavior itself; Can not influence the flow of (or not can appreciable impact) outdoor condenser when promptly regulating the indoor electric expansion valve corresponding to indoor condenser; Vice versa; And do not get rid of said electric expansion valve adjusting based on parameter between be independent or not related (as described above, being to exist related perhaps functional relation between wind pushing temperature and the degree of superheat for example).
Structure through temperature adjusting and dehumidifying of the present invention system; Can satisfy the requirement of cooling and heating load wide variation; When dehumidifying, can regulate wind pushing temperature continuously, make wind pushing temperature in 12 ℃~45C scope, regulate and control continuously and reposefully, and have higher temperature-controlled precision.
In the dehumidification system of above-mentioned a kind of temperature adjustment continuously, described compressor 1 can be piston type, rolling rotor-type or scroll compressor.
Refer now to Fig. 4; Show second embodiment according to temperature adjusting and dehumidifying of the present invention system; Its structure is identical substantially with embodiment shown in Figure 3; Except this dehumidification system also is included in the kind of refrigeration cycle in said compressor 1 porch the vapour liquid separator 13 that (promptly in kind of refrigeration cycle, at the upper reaches of compressor 1 and in the downstream of indoor evaporator 8) installs.In addition, in a second embodiment, at the air approaching side of indoor evaporator 8 filter 12 is installed and stops up indoor evaporator 6, in the air outlet slit side of indoor evaporator 8 water fender 11 is installed and takes away condensate to prevent air to prevent impurity.
Refer now to the 3rd embodiment shown in Figure 5 according to temperature adjusting and dehumidifying of the present invention system; Its parts composition is identical substantially with the embodiment shown in Fig. 4 with annexation; Be that outdoor condenser 2 adopts air-cooled condenser, the outdoor air that transports through outdoor fan 14 comes the high temperature refrigerant in the cooling chamber external condenser 2.In this temperature adjusting and dehumidifying system, said outdoor fan 14 can be the speed variable blower fan, through the heat again and the condensation temperature of outdoor fan 14 change in rotational speed regulating systems.
Refer now to the 4th embodiment shown in Figure 6 according to temperature adjusting and dehumidifying of the present invention system; Embodiment shown in the present among its parts composition and annexation and Fig. 4 is identical substantially; Be that outdoor condenser 2 adopts water-cooled condenser, the cooling water that transports through outdoor water pump 15 comes the high temperature refrigerant in the cooling chamber external condenser 2.In this temperature adjusting and dehumidifying system, said outdoor water pump 15 can be speed variable water pump or variable volume water pump, comes the heat again and the condensation temperature of regulating system through the variation of outdoor water pump 15 rotating speeds or volume.
