The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with specific embodiment, realization of the present utility model is described in detail.
As shown in Fig. 1～2, the preferred embodiment providing for the utility model.
The air injection enthalpy-increasing heat pump air conditioner that the present embodiment provides comprises major loop and tonifying Qi loop, wherein, major loop comprises compressor 19, cross valve 13, outdoor heat exchange machine 11, flash distillation machine 17 and the indoor heat exchanger 14 being sequentially communicated with by main line, wherein, outdoor heat exchange machine 11 is communicated with the first interface 131 of cross valve 13 and the outlet of flash distillation machine 17 respectively, and indoor heat exchanger 14 is communicated with the 3rd interface 133 of cross valve 13 and the import of flash distillation machine 17 respectively; Compressor 19 is communicated with the second interface 132 and the 4th interface 134 of cross valve 13 respectively.
When air injection enthalpy-increasing heat pump air conditioner is operated in refrigerating state, as shown in Figure 1, cold-producing medium circulates according to following flow direction: compressor 19, cross valve 13, outdoor heat exchange machine 11, flash distillation machine 17, indoor heat exchanger 14, cross valve 13, compressor 19.
When air injection enthalpy-increasing heat pump air conditioner is operated in while heating state, as shown in Figure 1, cold-producing medium circulates according to following flow direction: compressor 19, cross valve 13, indoor heat exchanger 14, flash distillation machine 17, outdoor heat exchange machine 11, cross valve 13, compressor 19.
Above-mentioned cross valve 13 plays a key effect, and it plays main line switching effect, realizes refrigerating state and heats the conversion between state.
Tonifying Qi loop in the present embodiment comprises the shape tube 20 that is connected to compressor 19 tonifying Qi imports, and this shape tube 20 is communicated with the tonifying Qi outlet 171 of flash distillation machine 17 by tonifying Qi pipeline 18, and shape tube 20 is arranged in the periphery of compressor 19.
Like this, when outdoor environment temperature is lower, air injection enthalpy-increasing heat pump air conditioner operates under the state of heating, in the time of need to carrying out tonifying Qi increasing enthalpy, now, cold-producing medium major loop to circulate direction as follows: from compressor 19 compressions, high-temperature high-pressure refrigerant is out through cross valve 13, enter indoor heat exchanger 14, carry out heat exchange, indoor temperature is raise, and the cold-producing medium after heat exchange enters in flash distillation machine 17, and flows to heat release in outdoor heat exchange machine 11 by flash distillation machine 17, the cross valve 13 of flowing through again, gets back in compressor 19 and compresses; And refrigerant vapour in flash distillation machine 17 is by the tonifying Qi outlet 171 of flash distillation machine 17, via tonifying Qi pipeline 18, then pass through shape tube 20, by the tonifying Qi import of compressor 19, enter and in compressor 19, carry out tonifying Qi.
Because compressor 19 can dispel the heat in the course of the work outwardly, its shape tube 20 is arranged in the periphery of compressor 19, the heat that shape tube 20 meeting absorption portion compressors 19 distribute, like this, when the refrigerant vapour in flash distillation machine 17 passes through shape tube 20, the part heat being absorbed by shape tube 20 can cooled dose of vapor absorption, thereby improve the temperature of refrigerant vapour and cross heat, greatly reduce from shape tube 20 and enter the liquid refrigerating agent content in the refrigerant vapour compressor 19, reduce the benefit gas carrying liquid phenomenon that may bring under low temperature environment, avoid compressor 19 to occur the hidden danger of liquid hammer, improve low-temperature heating effect and heat efficiency, and, also can improve air-conditioner reliability of operation, in addition, the used heat that shape tube 20 utilizes compressor 19 to distribute recycles, and that improves air-conditioner heats efficiency, environmental protection and energy saving.
In above-mentioned tonifying Qi pipeline 18, be also provided with magnetic valve 16, for controlling the unlatching in tonifying Qi loop or closing, like this, air injection enthalpy-increasing heat pump air conditioner is heating under state, can intelligent selection whether tonifying Qi increases enthalpy; For example, when outdoor environment temperature moderate, when air injection enthalpy-increasing heat pump air conditioner does not need to carry out tonifying Qi and increases enthalpy, can shut electromagnetic valve 16, tonifying Qi loop is in closed condition.
In order to make shape tube 20 can absorb more efficiently the heat that compressor 19 distributes, in the present embodiment, shape tube 20 is wrapped in the periphery of compressor 19, and inner surface 202 is attached on the outer surface of compressor 19; Certainly; consider and install and easy to assembly and needs; the inner surface 202 of shape tube 20 also can and the outer surface of compressor 19 between there is gap; directly be not attached to the outer surface of compressor 19; as long as keep gap enough little; can guarantee with shape tube 20 absorb heat that compressors 19 distribute can, this set-up mode is also within protection domain.
Further, shape tube 20 is spirally wrapped around the periphery of compressor 19, like this, can, so that shape tube 20 is evenly arranged in the periphery of compressor 19, improve its heat absorption efficiency.
In order to increase the contact area between shape tube 20 and compressor 19 outer surfaces, make shape tube 20 absorb to greatest extent the heat that compressor 19 distributes, the inner surface 202 of shape tube 20 is plane, after it is sticked on the outer surface of compressor 19, can guarantee contact area larger between shape tube 20 and compressor 19.
In the present embodiment, the outer surface 201 of shape tube 20 is arc surfaced, and give prominence to and arrange outwardly, like this, the in the situation that of shape tube 20 cross section effective volume, can be so that enter in shape tube 20 contacting of maximum area between refrigerant vapour and shape tube 20, thus can more efficiently to refrigerant vapour, heat, reduce liquid refrigerant in refrigerant vapour.
Shown in Fig. 2, the cross sectional representation of shape tube 20, its inner surface 202 is plane, and outer surface 201 is arc surfaced, and certainly, preferably, it is planar that its outer surface 201 is semi arch.
In main line between outdoor heat exchange machine 11 and flash distillation machine 17, be connected with first throttle valve 12, between indoor heat exchanger 14 and the main line of flash distillation machine 17, be connected with the second choke valve 15.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
