Description

Injection type air-conditioner

Technical field

The present invention relates to a kind of air-conditioner, particularly a kind ofly add the injection type air-conditioner that injector device is a power with circulating pump.

Background technology

Present family mainly is to adopt the mode of both vapor compression to freeze with air-conditioner, is called the steam compressing air conditioner device.Its kind of refrigeration cycle is: liquid refrigerant enters evaporimeter and vaporization heat absorption in evaporimeter through capillary or expansion valve step-down, becomes low-pressure steam, thereby produces refrigeration effect; And after low-pressure steam is inhaled into compressor, be compressed into high temperature and high pressure steam again by consuming mechanical power.High temperature and high pressure steam enters condenser again, heat release in condenser, is condensed into highly pressurised liquid; Highly pressurised liquid is again by capillary or expansion valve, is that the liquid-vapor mixture of low-temp low-pressure is got back to evaporimeter by throttling expansion again, thereby finishes a refrigeration work circulation.

And to keep kind of refrigeration cycle, just must constantly consume a large amount of mechanical energy by compressor.

In the steam compressing air conditioner device, the mechanical energy of compressor not only will provide kind of refrigeration cycle needed kinetic energy, also to roll up the interior energy of cold-producing medium, make cold-producing medium constantly become high temperature and high pressure steam from low temperature and low pressure steam, these heat energy that are transformed from mechanical energy are released in condenser with the heat energy that imports into from evaporimeter.As seen, in the steam compressing air conditioner device, have greatly mechanical energy be used as used heat or idle work slatterns, the utilization ratio of its energy is quite low.

Summary of the invention

Purpose of the present invention just provides a kind ofly can efficiently utilize mechanical energy, adds the injection type air-conditioner that injector device is a power with circulating pump.

The technical solution used in the present invention is: injection type air-conditioner, and it comprises fluid reservoir, condenser, evaporimeter, regenerator, injector and circulating pump, and the jet of injector is connected with the circulating-pump outlet pipe, and the inlet of circulating pump is connected with the fluid reservoir pipe; Pipe connects between regenerator first outlet and second inlet, is serially connected with evaporimeter and expansion valve on the pipeline respectively; First inlet of regenerator is connected with the fluid reservoir pipe, and second outlet is connected with the suction inlet pipe of injector; The outlet of injector, condenser, check valve, fluid reservoir are managed connection successively; Contain refrigerant in fluid reservoir and the pipeline.

Adopt technique scheme, a part of liquid refrigerating medium in the fluid reservoir flows out by the pressurized injector that enters of circulating pump from fluid reservoir, jet expansion step-down, expansion at injector, form the ultrahigh speed fluid, near its suction chamber jet expansion causes high vacuum, refrigerant in the evaporimeter is constantly evaporated under the effect of pressure reduction, form Low Temperature Steam and enter suction chamber, be involved in mixing chamber by the ultrahigh speed fluid of jet expansion then.Like this, vapour, liquid two fluid streams mix and slow down, boost at mixing chamber, mix vapour-liquid stream (perhaps supersaturated vapor) and enter the condenser cooling, form liquid working substance and flow back to fluid reservoir; Another part liquid refrigerating working medium in the fluid reservoir then constantly enters evaporimeter by expansion valve or capillary under the effect of pressure reduction, replenish the refrigeration working medium that is evaporated in the evaporimeter, forms the working medium circulation.Evaporimeter and condenser can pass through flowing of refrigerant like this, play the effect to environment temperature reduction and heating.

In order to make sordid refrigerant not influence work, on first inlet of circulating pump and fluid reservoir and regenerator and the pipeline between the fluid reservoir, be serially connected with filter respectively.

The invention has the beneficial effects as follows: because the present invention uses circulating pump rather than compressor to provide power as kind of refrigeration cycle, and the kinetic energy and the potential energy of circulating pump work the time only increasing cold-producing medium, almost do not increase the interior energy of cold-producing medium, mechanical energy does not slattern as used heat or idle work greatly, so under the identical situation of refrigerating capacity, the power that the present invention is consumed in kind of refrigeration cycle is more much smaller than the power that steam compressing air conditioner device consumed, power approximately has only 1/2nd of steam compressing air conditioner device, and energy-saving effect is obvious.
