[specific embodiment]
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and the specific embodiment the present invention done further detailed explanation.
Alleged here " embodiment " or " embodiment " are meant special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different in this manual local " in one embodiment " that occur not are all to refer to same embodiment, neither be independent or optionally mutually exclusive with other embodiment embodiment.
Fig. 1 is that air-conditioning system in one embodiment of the present of invention is at the structural principle sketch map of heating mode.As shown in the figure, said air-conditioning system comprises compressor 1, four-way change-over valve 2, the first heat exchangers 4, and throttle mechanism 5, the second heat exchangers 7 are with the pipeline 3,9 and 10 of each member connection.
When air-conditioning system operates in heating mode; High-temperature high-pressure refrigerant gas by compressor 1 discharge; Get into second heat exchanger 7 through four-way change-over valve 2 and pipeline 9 backs, be condensed into high-temperature high-pressure refrigerant liquid after cold-producing medium and room air carry out heat exchange in second heat exchanger 7, this moment, second heat exchanger 7 was as condenser; Cold-producing medium is through throttle mechanism 5 throttling step-downs afterwards, and the gas-liquid two-phase state that becomes low temperature, low pressure gets into first heat exchanger 4.Flash to low-temperature low-pressure refrigerant gas after cold-producing medium and outdoor air carry out heat exchange in first heat exchanger 4; This moment, first heat exchanger 4 was as evaporimeter; Cold-producing medium gets into the air entry of compressor 1 through pipeline 3, four-way change-over valve 2 and pipeline 10 afterwards; In compressor 1, compress, become the gas of HTHP.Thus, form one and complete heated circulation.
Fig. 2 is that air-conditioning system in one embodiment of the present of invention is at the structural principle sketch map of refrigeration mode.When said air-conditioning system operates in refrigeration mode; High-temperature high-pressure refrigerant gas by compressor 1 discharge; Get into first heat exchanger 4 through four-way change-over valve 2 and pipeline 3 backs, be condensed into high-temperature high-pressure refrigerant liquid after cold-producing medium and outdoor air carry out heat exchange in first heat exchanger 4, this moment, first heat exchanger 4 was as condenser; Cold-producing medium is through throttle mechanism 5 throttling step-downs afterwards, and the gas-liquid two-phase state that becomes low temperature, low pressure gets into second heat exchanger 7.Flash to low-temperature low-pressure refrigerant gas after cold-producing medium and room air carry out heat exchange in second heat exchanger 7; This moment, second heat exchanger 7 was as evaporimeter; Cold-producing medium gets into the air entry of compressor 1 through pipeline 9, four-way change-over valve 2 and pipeline 10 afterwards; In compressor 1, compress, become the gas of HTHP.Thus, formed a complete kind of refrigeration cycle.
Please combine illustrated in figures 1 and 2ly, first heat exchanger 4 in the said air-conditioning system is placed on outdoor, can be called as off-premises station, and second heat exchanger is placed 7 and is placed on indoorly, can be called as indoor set.Usually, compressor, throttle mechanism 5 also is placed on outdoor with first heat exchanger 4 with four-way change-over valve 2.The indoor set 13 of said air-conditioning system also includes aqueous vapor generator 11 and blower fan 12 except comprising second heat exchanger 7.For the air-conditioning system among clearer understanding the present invention, Fig. 3 shows the structural principle sketch map of the indoor set 13 of said air-conditioning system.
As shown in Figure 3, except second heat exchanger 7, aqueous vapor generator 11 and blower fan 12, said indoor set 13 also includes return air inlet 130, air outlet 131 and water pond 132.When air-conditioning work, no matter be refrigeration mode or heating mode, under the driving of blower fan 12, the air that gets into from said return air inlet 130 passes said second heat exchanger 7 backs and is blown through said air outlet 131.
Said in the present invention air-conditioning system has increased a humidification/dedusting pattern; Under this pattern; Said aqueous vapor generator 11 can generate aqueous vapor, and this aqueous vapor is mixed the formation mist with the air that the return air inlet 130 of indoor set 13 gets into, and this mist passes second heat exchanger, 7 backs and seen off said air outlet 131; Contain like this in the air inlet chamber of aqueous vapor, thereby can keep air humidity.In concrete the application, after having used 1 hour heating mode or refrigeration mode, can air-conditioning be transferred to humidification dedusting pattern, can keep indoor air humidity like this.In addition, humidification dedusting pattern can with refrigeration mode and heating mode in any the coexistence, so both played the effect that heats or freeze, also play the effect of humidification dedusting.
Simultaneously, pass from second heat exchanger 7 owing to have the mist of aqueous vapor, the part aqueous vapor will condense on the fin of water droplet attached to second heat exchanger 7; Fall from fin at last; Flow to water pond 132, flow out indoor set 13 through water pond 132 afterwards, can reach the fin of cleaning second heat exchanger 7 and the effect of other internal parts like this; Keep the inner cleaning of air-conditioning, therefore this pattern also can be called as the dedusting pattern.
Said aqueous vapor generator 11 can adopt hyperacoustic principle that water is become aqueous vapor; Its operation principle is to use a transducer to convert electric energy into mechanical energy; In water, make water atomization, spread to air, reach the purpose that produces aqueous vapor in this way with a kind of very fast concussion.In addition, also can adopt the mode of pressure atomization, convert water to water smoke.Said aqueous vapor generator 11 includes the water receptacle (not shown) that is used to be filled with water, and the user can pour water in the said water receptacle into.In water receptacle, close said aqueous vapor generator 11 automatically after anhydrous, to avoid that aqueous vapor generator 11 is produced unnecessary harms.In one embodiment, can be used in water points out with indicator lamp seldom the time.
According to same principle, the present invention can also be embodied as a kind of method.Fig. 4 is the schematic flow sheet of the humidification dust collection method 40 of air-conditioning system of the present invention.As shown in Figure 4, the humidification dust collection method 40 of said air-conditioning system comprises the steps.
Use when usefulness when said humidification dedusting pattern is can be with refrigeration mode common, said humidification dedusting pattern are also can be with heating mode common.
Above-mentioned explanation has fully disclosed the specific embodiment of the present invention.It is pointed out that any change that technical staff's specific embodiments of the invention of being familiar with this field is done does not all break away from the scope of claims of the present invention.Correspondingly, the scope of claim of the present invention also is not limited only to previous embodiment.
