Fig. 2 is the structural representation of the electric auxiliary heating system among Fig. 1.
The specific embodiment:
Below in conjunction with the specific embodiment, describe the present invention in detail.Should be understood that these embodiments only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1; A kind of heat pump air conditioner; It comprises indoor set 1 and off-premises station 2, and said off-premises station 2 comprises the gas-liquid separator 22 that is arranged in the shell, filter 23, capillary 24, compressor 25, first muffler 21, second muffler 26, cross valve 27, outdoor heat exchange valve 28, electric auxiliary heating system 30, magnetic valve 20, check valve 29; Said indoor set 1 comprises indoor heat converter 11; Said indoor heat converter 11 two ends connect said cross valve 27 and said filter 23 respectively; And said filter 23 other ends connect said outdoor heat converter 28 through said capillary 24, and said outdoor heat converter 28 other ends connect said cross valve 27, and said gas-liquid separator 22 connects said cross valve 27 through one first muffler 21; Said compressor 25 connects said cross valve 27 through said second muffler 26; And said compressor 25 is connected with said gas-liquid separator 22, and said check valve 29 is parallel to the two ends of capillary 24, and magnetic valve 20 1 ends are connected between the cross valve 27 and second muffler 26; The other end is connected between outdoor heat converter 28 and the capillary 24; Said electric auxiliary heating system 30 is located at the vicinity of said in-room switch 28, and should electricity auxiliary heating system 30 contains a said controller and be provided with temperature sensor 305, constantly the precise monitoring temperature.
As shown in Figure 2; Said electric auxiliary heating system comprises that blast switch detects mouth 301, blast switch 304, heater 302, temperature sensor 303, controller 305, power supply 306; Said controller 305 is connected with said power supply 306; And said controller 305 connects the described heater of control 302, temperature sensor 303 and blast switch 304; Said blast switch 304 connects said blast switch through pipeline and detects mouthfuls 301, and said blast switch detect mouthfuls 301 be located at described off-premises station adjacent to, preferably described blast switch detects the place ahead that mouth is located at described off-premises station heat exchanger 28 fan (not shown)s.
Operation principle of the present invention is: when heat pump air conditioner refrigeration, cross valve 27 switching-overs make solid line connection among the figure.At this moment, indoor heat converter 11 becomes evaporimeter, and outdoor heat converter 28 becomes condenser.After cooling medium heats in indoor heat converter 11, cross hot gas from the low-temp low-pressure of indoor heat converter 11 and get into gas-liquid separators 22 through the cross valve 27 and first silencer 21, isolate liquid after; Cross hot gas and be compressed the gas discharge that machine 25 suctions are collapsed into HTHP, after passing through second muffler 26, get into cross valve 27, inlet chamber outer heat-exchanger 28 heat release condensations more then; Become supercooled liquid; Supercooled liquid becomes the low-temp low-pressure two-phase fluid after capillary 24 resistance step-downs, get into indoor heat converter 11 evaporation heat absorptions then, and this process can play cooling effect to indoor air; This process of repetitive cycling is as shown in Figure 1 then.
When heat pump air conditioner pyrogenicity, cross valve 27 switching-overs make dotted line connection among the figure.This moment, indoor heat converter 11 became condenser, and outdoor heat converter 28 becomes evaporimeter.Cross hot gas from the low-temp low-pressure of outdoor heat converter 28 and get into gas-liquid separator 22 through the cross valve 27 and first silencer 21; Process is isolated liquid after separating, and the dry hot gas of crossing is compressed the gas discharge that machine 25 suctions are collapsed into HTHP, and gas gets into indoor heat converters 11 heat release condensations (at this moment through cross valve 27; Room air is heated); Become supercooled liquid, supercooled liquid becomes the low-temp low-pressure two-phase fluid after capillary 24 resistance step-downs, the 28 evaporation heat absorptions of inlet chamber outer heat-exchanger; Cross hot gas subsequently and get into next circulation through cross valve 27 and gas-liquid separator 22, as shown in Figure 1.At this moment; If when outdoor temperature was lower than the set temperature of controller 305, at this moment, electric auxiliary heating system 30 was started working; Outdoor heat converter 28 temperature is on every side risen; Cooling medium can be gasified from absorbing sufficient amount of heat on every side, improve the heating effect of air-conditioning, its pyrogenicity effect will be strengthened greatly.Increase and use air conditioner comfort winter.
Because electric auxiliary heating system 30 has temperature sensor 303, when outdoor temperature reached the temperature that controller 305 sets, outdoor heat converter 28 is absorption chamber warm outward fully; The evaporation refrigerant; Compressor can high efficiencyly turn round, and at this moment, electric auxiliary heating system 30 is idle; Have only when outdoor temperature is lower than controller 305 temperature is set, outdoor heat converter 28 does not have enough heats fully to gasify by refrigerant, and the gaseous coolant that get into compressor this moment has minimizing; Compressor efficiency is very low, and heating effect is just very poor like this, in order to improve his operating efficiency; At this moment, electric auxiliary heating system 30 work, the air in the heating off-premises station; Let refrigerant can absorb sufficient endothermic gasification, increase work efficiency energy savings.
When the heat pump type air conditioner machine ran on heating condition, at this moment outdoor heat converter 28 fans were started working, and therefore produced blast; Detect mouthful blast that 301 detections produce through blast switch; And this blast is transferred to controller 305, controller 305 produces signals, with heater 302 conductings; Begin heating, power supply 306 detects mouthful 301 power supplies for controller 305, heater 302, temperature sensor 303, blast switch 304 and blast switch; The described blast switch of controller 305 control blast switch 304 switches detects mouth 301.
Owing to added electric auxiliary heating system, the air in the heating off-premises station lets refrigerant can absorb sufficient endothermic gasification, increases work efficiency energy savings.
