Specific embodiment
In the following detailed description, a large amount of specific details are proposed, in order to provide to thorough reason of the invention Solution.However it will be understood by those of ordinary skill in the art that, even if can also implement this hair without these specific details It is bright.In other cases, well-known method, process, component and circuit are not described in, with Exempt to influence the understanding of the present invention.
With reference to shown in Figure 1, embodiments in accordance with the present invention, air-conditioner includes compressor 1, four-way Valve 2, indoor heat exchanger 3 and outdoor heat exchanger, outdoor heat exchanger include the First Heat Exchanger being arranged in parallel 4 and second heat exchanger 5, the second heat exchanger 5 is arranged on the bottom of First Heat Exchanger 4, the second heat exchanger 5 It is connected on the pipeline of four-way valve 2 and is provided with the first control valve 6, air-conditioner also includes bypass line 7, One end of bypass line 7 is connected on the pipeline between the first control valve 6 and the second heat exchanger 5, bypass Second end of pipeline 7 is connected on the pipeline between four-way valve 2 and indoor heat exchanger 3, bypass line 7 On be provided with the second control valve 8.
When air-conditioner is under refrigeration mode, the first control valve 6 is opened, and the second control valve 8 is closed, Refrigerant carries out condensing heat-exchange from the heat exchanger 5 of First Heat Exchanger 4 and second simultaneously, then into interior Heat exchanger 3 is evaporated heat absorption, re-enters into be compressed in compressor 1 afterwards, so as to complete one Individual kind of refrigeration cycle.Because the heat exchanger 5 of First Heat Exchanger 4 and second condenses heat release simultaneously, therefore can carry The refrigerating efficiency of air-conditioner high.
When air-conditioner is under heating mode, the first control valve 6 is opened, and the second control valve 8 is closed, Refrigerant steams from after the condensation heat release outflow of indoor heat exchanger 3 through the heat exchanger 5 of First Heat Exchanger 4 and second Hair heat absorption, afterwards into being compressed in compressor 1, so that completing one heats circulation.Due to first The heat exchanger 5 of heat exchanger 4 and second evaporation endothermic simultaneously, therefore can be by First Heat Exchanger 4 and second Heat exchanger 5 improves the heat absorption efficiency of air-conditioner, so as to improve the heating efficiency of air-conditioner.
When air-conditioner is in be heated under deice mode, the second control valve 8 is opened, and the first control valve 6 is closed Close, now refrigerant is divided into two-way from after the outflow of compressor 1, enters second through bypass line 7 all the way Heat exchanger 5 condenses heat release, is absorbed heat into First Heat Exchanger 4 afterwards, and another road enters into interior and changes After the condensation heat release of hot device 3, enter into First Heat Exchanger 4 and absorbed heat.Refrigerant is in First Heat Exchanger After 4 completion evaporation endothermics, enter into and be compressed in compressor 1, so that completing one heats deicing Circulation.During carrying out heating deicing, air-conditioner still can normally run without shutting down.The The condensation heat release of two heat exchangers 5 can heat the bottom of outdoor heat exchanger such that it is able to outdoor heat exchanger Chassis carries out ice-melt, can easily to outdoor heat exchanger by the thermal discharge of the second heat exchanger 5 of control Chassis is heated, and can be prevented effectively from and be caused damage to chassis because temperature is too high, while also can Heat release effectively is condensed using the second heat exchanger 5, the utilization rate of the energy is improved, energy loss is reduced.
First Heat Exchanger 4 is integrally formed with the second heat exchanger 5, and outdoor heat exchanger can be made to remain one It is overall, easily facilitate installation and shift.
Dividing plate is provided with outdoor heat exchanger, outdoor heat exchanger is divided into First Heat Exchanger 4 and by dividing plate Two heat exchangers 5, can better ensure that the integrated effect of outdoor heat exchanger, while improve first exchanging heat Heat exchange efficiency between the heat exchanger 5 of device 4 and second, ability deicing efficiency when raising heats deicing.
First throttle valve 9 is provided with pipeline between First Heat Exchanger 4 and indoor heat exchanger 3, is passed through The aperture of first throttle valve 9 is adjusted, the refrigerant flow at First Heat Exchanger 4 can be adjusted, so as to adjust Save the heat exchange property of First Heat Exchanger 4 so that the heat exchange property of First Heat Exchanger 4 and the entirety of air-conditioner Performance matches, and improves the Energy Efficiency Ratio of whole air-conditioner.
Second throttle 10 is provided with pipeline between second heat exchanger 5 and indoor heat exchanger 3.In sky Device is adjusted when carrying out heating deicing, can be by adjusting the aperture of the second throttle 10, regulation second is changed The exothermic temperature of hot device 5, so as on the basis of avoiding the second heat exchanger condensation exothermic temperature too high, carry The ice-melt efficiency of outdoor heat exchanger bottom high.
First Heat Exchanger 4 is provided with the first temperature sensor 11, second near one end of indoor heat exchanger 3 Heat exchanger 5 is provided with second temperature sensor 12 near one end of indoor heat exchanger 3, such that it is able to more Temperature of the heat exchanger 5 of First Heat Exchanger 4 and second near the one end of indoor heat exchanger 3, energy are grasped exactly Enough apertures to first throttle valve 9 and second throttle 10 are more accurately controlled.
First Heat Exchanger 4 is provided with three-temperature sensor 13 near one end of four-way valve 2.
The first control control valve 8 of valve 6 and second is magnetic valve, can be controlled by controller, Easily facilitate the Automated condtrol for realizing air-conditioner, the simpler convenience of control structure.
Accounting of second heat exchanger 5 in outdoor heat exchanger should be as far as possible small, so as to ensure that air-conditioner is entering When row heats deicing, the evaporation of outdoor heat exchanger will not be too influenceed because of the heat release of the second heat exchanger 5 Endothermic effect, it is ensured that the service behaviour of air-conditioner, can provide enough for the deicing of outdoor heat exchanger again Heat, it is ensured that the deicing efficiency of outdoor heat exchanger.Preferably, the volume of the second heat exchanger 5 is the first heat exchange 1/10 to the 1/5 of the volume of device 4.
By using above-mentioned air-conditioner, the heating capacity of interior can be borrowed, carrying out electricity compared to chassis adds The ice-melting mode of heat, air-conditioner of the invention can save 60%~70% energy, greatly reduce the energy Loss, saves the energy.
The explanation of above example is only intended to help and understands the method for the present invention and its core concept;Meanwhile, For those of ordinary skill in the art, according to thought of the invention, in specific embodiment and model is applied Place and will change, in sum, this specification content should not be construed as limiting the invention.
