Abstract
The utility model relates to a heat-pump air conditioner, which comprises one or more than one outdoor-machine module unit consisting of a compressor, a four-way valve, an outdoor heat exchanger, a high-pressure liquid container, a low-pressure liquid container, a first throttling device and an electromagnetic valve; wherein, the electromagnetic valve is arranged on a pipeline arranged between the high-pressure liquid container and the compressor. Outdoor-machine module units are connected in parallel and then connected with an indoor machine by a liquid pipe and a gas pipe. The utility model is characterized in that a second throttling device is arranged on the pipeline arranged between the high-pressure liquid container in each outdoor-machine module unit and the indoor machine. The coolant of the utility model, which is condensed by the indoor machine, firstly flows through the second throttling device, and the coolant throttled down is separated into gaseous coolant and liquid coolant in the high-pressure liquid container. And then the gaseous coolant comes into the compressor to be compressed secondarily to improve the gas-intake capacity and the compression power of the compressor. The liquid coolant flows through the first throttling device to be cooled and depressurized again to further improve the temperature difference for heat exchanging, thereby absorbing a great amount of heat by the outdoor heat exchanger, and greatly improving the heating capability.
Description
Technical field
The utility model is a kind of heat pump air conditioner, particularly a kind of heat-flash type heat pump air conditioner that can improve heating effect.
Background technology
Traditional heat pump air conditioner adopts a throttling method, under low temperature environment, the evaporating temperature of outdoor heat exchanger is higher, heat transfer temperature difference is very little, the heat that absorbs is less, and because refrigerant pressure drop when throttling is big, produced tangible irreversible loss, the thermodynamic perfect degree of circulation is reduced, above-mentioned situation all will cause heating capacity to be decayed significantly, therefore the application under low temperature environment of conventional heat pump air-conditioner can be subjected to certain restriction, and reflect also that in the market the situation that the conventional heat pump air-conditioner do not heat winter is very outstanding, for this reason, some producers take to increase the auxilliary pyrolysis of a large amount of electricity the problems referred to above of determining, this is negative effect to the brand image of manufacturer and has increased manufacturing cost, makes user's cost of use significantly increase again.
The utility model content
The purpose of this utility model is to provide a kind of heat pump air conditioner that can improve heating effect under low temperature environment, to overcome weak point of the prior art.
A kind of heat pump air conditioner by this purpose design, comprise one and the above off-premises station modular unit of forming by compressor, cross valve, outdoor heat exchanger, high pressure fluid reservoir, low-pressure liquid storing tank, first throttle device and magnetic valve, wherein magnetic valve is installed on the pipeline between high pressure fluid reservoir and the compressor, above-mentioned off-premises station modular unit is connected in parallel, be connected with indoor set by liquid pipe and tracheae, its architectural feature is that the pipeline between above-mentioned each off-premises station modular unit mesohigh fluid reservoir and the indoor set is provided with second throttling arrangement.
Above-mentioned second throttling arrangement and first throttle device are electric expansion valve.
The utility model is owing to adopt the structure that is provided with second throttling arrangement on the pipeline between each off-premises station modular unit mesohigh fluid reservoir and the indoor set, through indoor set condensed liquid refrigerants second throttling arrangement of flowing through earlier, make the refrigerant after the throttling in the high pressure fluid reservoir, be separated into gaseous state and liquid refrigerants, gaseous coolant enters inspiratory capacity and the increase compression horsepower that compressor carries out second-compressed raising compressor then, liquid refrigerants process first throttle device is decrease temperature and pressure once more, evaporating temperature is lower, further improve heat transfer temperature difference, thereby absorb more heat by outdoor heat exchanger, improved heating capacity greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, comprise one and the above off-premises station modular unit of forming by compressor 1, cross valve 2, outdoor heat exchanger 3, high pressure fluid reservoir 4, low-pressure liquid storing tank 5, first throttle device 7 and magnetic valve 11, wherein magnetic valve 11 is installed on the pipeline between high pressure fluid reservoir 4 and the compressor 1, above-mentioned off-premises station modular unit is connected in parallel, be connected with indoor set 10 by liquid pipe 8 and tracheae 9, the pipeline between above-mentioned each off-premises station modular unit mesohigh fluid reservoir 4 and the indoor set is provided with second throttling arrangement 6.Above-mentioned second throttling arrangement 6 and first throttle device 7 are electric expansion valve.
Under the low-temperature heating environment, at first control the throttle opening of second throttling arrangement 6 and first throttle device 7 well, make air-conditioning system be in optimal operational condition, in the high pressure fluid reservoir, be separated into gaseous state and liquid refrigerants through the refrigerant after the second throttling arrangement throttling, magnetic valve 11 is opened, make gaseous coolant enter compressor and carry out inspiratory capacity and the increase compression horsepower that second-compressed improves compressor, while liquid refrigerants process first throttle device is decrease temperature and pressure once more, evaporating temperature is lower, further improve heat transfer temperature difference, thereby absorb more heat by outdoor heat exchanger, improved heating capacity greatly.
Under the refrigeration mode, magnetic valve 11 cuts out, control the throttle opening of second throttling arrangement and first throttle device well, can not have influence on original refrigerating capacity and Energy Efficiency Ratio.
