Abstract

The present invention discloses a regenerative refrigeration cycle system air conditioner. It includes compressor, condenser, throttle device, evaporator and recuperative heat exchanger. The described recuperative heat exchanger includes a cylindrical tank body whose top portion and bottom portion are respectively equipped with low-pressure refrigerant outlet and inlet connected with compressor suction pipe and evaporator outlet, a straight tube which is placed in the interior of tank body along vertical direction and whose upper and lower ends are respectively connected with condenser outlet and throttle device and a heat-exchanging coiled tube, said coiled tube and straight tube are integrally formed into one body.

Description

Air conditioner for regenerative cooling circulation system
Technical field
The present invention relates to a kind of air-conditioner, particularly relate to a kind of air conditioner for regenerative cooling circulation system.
Background technology
Usually, air-conditioner is a kind of device that makes its inner refrigerant carry out the kind of refrigeration cycle be made up of compression process, condensation process, expansion process and evaporation process.In air-conditioner, the refrigerant that becomes high-temperature high-pressure state through overcompression can dispel the heat to the outside in condenser, and when flowing through throttling arrangement, significantly reducing its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter then, flow back to compressor at last again.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.Because this cooling cycle system does not have the backheat switch, when this air-conditioner moves under underload, the refrigerant that flows out from evaporimeter can not be evaporated fully, thereby can cause compressor liquid hit phenomenon to occur.In addition, for the whole refrigerant of condensation, the heat exchange area of condenser must be enough big, will increase the volume of off-premises station so undoubtedly, and can make off-premises station a large amount of air heating on every side.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of leaking heat that can make full use of system, reduce the off-premises station volume and, prevent liquid hit phenomenon, and can improve the air conditioner for regenerative cooling circulation system of Energy Efficiency Ratio the influence of surrounding environment.
In order to achieve the above object, air conditioner for regenerative cooling circulation system provided by the invention comprises compressor, condenser, throttling arrangement and evaporimeter, and described air conditioner for regenerative cooling circulation system also comprises a Returning heat-exchanger.
Described Returning heat-exchanger comprises that a top and bottom are respectively equipped with the circle tube tank body of the low pressure refrigerant outlet that links to each other with evaporator outlet with compressor suction duct, inlet and vertically are arranged on the inside of tank body, upper and lower side is the straight tube that links to each other with condensator outlet and throttling arrangement respectively, and middle shape and the heat exchange coil integrally formed with straight tube in the shape of a spiral.
Described heat exchange coil is a built-in screw-type or external finned.
Air conditioner for regenerative cooling circulation system provided by the invention is the refrigerant temperature that utilizes in its system the Returning heat-exchanger that is provided with to raise to enter compressor and reduces the refrigerant temperature that enters throttling arrangement, not only can make full use of the leaking heat of system like this, thereby improve the Energy Efficiency Ratio of system, and can reduce the influence of the volume of condenser in the off-premises station and system surrounding environment.In addition, Returning heat-exchanger can utilize existing fluid reservoir to reequip, thereby is convenient to processing.
Description of drawings
Below in conjunction with the drawings and specific embodiments air conditioner for regenerative cooling circulation system provided by the invention is elaborated.
Fig. 1 is that air conditioner for regenerative cooling circulation system provided by the invention constitutes schematic diagram.
Fig. 2 is a Returning heat-exchanger structural representation in the air conditioner for regenerative cooling circulation system provided by the invention.
The specific embodiment
To shown in Figure 2, air conditioner for regenerative cooling circulation system provided by the invention comprises compressor 1, condenser 2, throttling arrangement 3 and evaporimeter 4 as Fig. 1, and described air conditioner for regenerative cooling circulation system also comprises a Returning heat-exchanger 5.Described Returning heat-exchanger 5 comprises that a top and bottom are respectively equipped with the low pressure refrigerant outlet 6 that links to each other with 4 outlets of compressor 1 air intake duct and evaporimeter, 7 circle tube tank body 8 and vertically be arranged on the inside of tank body 8 enters the mouth, upper and lower side is the straight tube that links to each other with condenser 2 outlets and throttling arrangement 3 respectively, and middle shape and the heat exchange coil 9 integrally formed with straight tube in the shape of a spiral.Described heat exchange coil 9 is a built-in screw-type or external finned, can improve heat exchange efficiency like this.When air conditioner for regenerative cooling circulation system provided by the invention moves, compressor 1, condenser 2, throttling arrangement 3 is identical with the effect in no backheat cooling cycle system air-conditioner with evaporimeter 4, Returning heat-exchanger 5 then can make from evaporimeter 4 low temperature refrigerant that returns compressor 1 and the high normal pressure and temperature refrigerant that enters throttling arrangement 3 from condenser 2 within it portion carry out heat exchange, thereby the refrigerant temperature reduction that the refrigerant temperature that enters compressor 1 is raise and enter throttling arrangement 3, not only can make full use of the leaking heat of system like this, thereby improve the Energy Efficiency Ratio of system, and can reduce the influence of the volume of condenser 2 in the off-premises station and system surrounding environment.In addition, because the refrigerant that flows out from evaporimeter 4 can obtain evaporation fully, thereby compressor 1 liquid hit phenomenon can not occur again, and the running parameter of the circulatory system and characteristic are changed.In addition, Returning heat-exchanger 5 can utilize existing fluid reservoir to reequip, and so not only is convenient to processing, and need not to be provided with fluid reservoir again, thereby can not increase considerably cost.Particularly air conditioner for regenerative cooling circulation system and no backheat cooling cycle system air-conditioner are when having identical operating temperature with identical specific refrigerating effect, and the former pressure ratio, compress work per mass and unit expansion work are all much smaller than the latter.This is that pressure is approximate constant because temperature will rise after the gas superheat of low-temp low-pressure, and enthalpy and specific volume rise, and density then descends, so the compression wasted work reduces.
