Abstract
The open heat pump uses the mixture of air and water as working medium and consists of three main parts, including axial turbine, heating and humidifying chamber and axial turbine compressor. The rotor of the axial flow turbine and the rotor of the axial flow turbine compressor are connected through a transmission shaft and driven by a high-rotation-speed power source. Because of the characteristics of high efficiency and large flow of the axial flow turbo machine, the heat pump has the characteristics of no toxicity, no pollution, no combustion, small volume, large heating capacity, high heat supply coefficient, low cost and the like. The utility model is particularly suitable for heating and ventilation in areas with low grade heat energy.
Description
The utility model relates to a kind of open type heat pump, this heat pump is applicable to heating and ventilation.
The heat pump of heating at present,, ventilation usefulness adopts the contrary circulation of both vapor compression more.This heat pump is made up of vapour compression machine, condenser, choke valve, evaporimeter and connecting line, and its working medium is not Lyons or ammonia.Not there is destruction in Lyons to atmospheric ozone layer, and ammonia has excitant peculiar smell, explosive.Therefore, seek a functional and free of contamination heat pump fluid substitute and become one big problem in the present age.Owing to be working medium, adopt the contrary cycle performance coefficient of the piston compressor that efficient is low and flow is little low with air with the mixture of air-water, so be not used in open type heat pump.Can make it become possibility after adopting the axial-flow turbine turbine of existing high efficiency, big flow and axial-flow turbine compressor.
The purpose of this utility model is that a kind of open type heating, ventilation heat pump techniques will be provided, to solve the deficiency of prior art.
The purpose of this utility model is achieved in that utilizes existing axial-flow turbine turbine and axial-flow turbine compressor respectively as the decompressor and the compressor of heat pump, adopts air-water vapour as its working medium simultaneously.Like this, just formed one, the open type air that warming and humidifying chamber and axial-flow turbine compressor three big critical pieces are formed-water vapour compression heat pump by the axial-flow turbine turbine.
Open type air-water vapour compression heat pump is work like this: utilize the rotor of high rotating speed drive power source heat pump, the warming and humidifying between axial-flow turbine turbine outlet and axial-flow turbine compressor inlet is indoor just can to produce negative pressure.At this moment, the atmosphere of handling will enter the cooling of expanding of axial-flow turbine turbine and become the humid air stream of low-temp low-pressure, and the low-temp low-pressure humid air stream of Huo Deing is treated as the humid air stream that has tiny water smoke by the water warming and humidifying in the warming and humidifying chamber thereafter.At last, the humid air stream that has tiny water smoke that obtains previously enters the axial-flow turbine compressor and compresses, and can obtain the high temperature humid air stream for the heating or the use of ventilating.
The utility model advantage compared with prior art is: this heat pump is a working medium with the mixture of empty G﹠W, owing to adopted efficient height, axial-flow turbine machinery that flow is big, so characteristics such as that this heat pump has is nontoxic, pollution-free, do not burn, volume is little, heating capacity is big, coefficient of heat supply is high, cost is low.The utility model is specially adapted to big-and-middle-sized heating, the ventilation in low grade heat energy area.
Description of drawings:
Fig. 1 is the fundamental diagram of open type air-water vapour compression heat pump.
Fig. 2 is the structural representation of a kind of open type air-water vapour compression heat pump.
Wherein:
1. axial-flow turbine turbine 4. power transmission shafts
2. air entraining pipe 5. axial-flow turbine compressors
3. warming and humidifying chamber
Below in conjunction with accompanying drawing, describe the detailed process that the utility model purpose realizes in detail.
With reference to Fig. 2, this open type air-water vapour compression heat pump is a working medium with the mixture of empty G﹠W.The rotor of the rotor of axial-flow turbine turbine (1) and axial-flow turbine compressor (5) is connected by power transmission shaft (4), by high rotating speed drive power source, one warming and humidifying chamber (3) is arranged therebetween, more than between the import and export of gas channel of each critical piece successively head and the tail be connected to each other, also can add an air entraining pipe between two critical pieces as required, formation is with axial-flow turbine turbine (1), and open type air-water vapour that warming and humidifying chamber (3) and axial-flow turbine compressor (5) three big critical pieces are formed compresses heat pump.Axial-flow turbine compressor (5) pressure ratio is less than 2.5, and warming and humidifying chamber (3) can be spray chambers, also can be a cavity of being made up of heat exchanger and one group of water atomizing nozzle or steam jet, and the indoor water of warming and humidifying is discharged by water pump.During work, the rotor of high rotating speed drive power source heat pump, the lining, warming and humidifying chamber (3) that is positioned between axial-flow turbine turbine (1) outlet and axial-flow turbine compressor (5) import can produce negative pressure.At this moment, the atmosphere of handling will enter axial-flow turbine turbine (1) expand the cooling become the low-temp low-pressure humid air stream, enter lining, warming and humidifying chamber (3) warming and humidifying after underspeeding by air entraining pipe (2a) then and be treated as the humid air stream that has tiny water smoke.At last, the humid air stream that has tiny water smoke enters axial-flow turbine compressor (5) by air entraining pipe (2b) again and compresses, can be for the heating or the use of ventilating thereby obtain the high temperature humid air.If select that pressure ratio is 1.7 for use, efficient is 0.87 axial-flow turbine compressor (5) and efficient is 0.87 axial-flow turbine turbine (1), when atmospheric temperature is 5 ℃, can obtain the humid air stream of low-pressure low-temperature in axial-flow turbine turbine (1) outlet, when be heated humidification in the preceding working medium of axial-flow turbine compressor (5) be 5 ℃ humid air, can obtain about 35 ℃ humid air after axial-flow turbine compressor (5) compression.
