Abstract
The invention belongs to the field of heat pump industry and realizes a new structure for greatly improving the energy efficiency ratio of a heat pump. The invention mainly relates to a method for designing a motor applicable to refrigerant decompression to substitute an expansion valve and connecting the output shaft of the motor with the main shaft of a compressor motor to recover energy so as to reduce input of electrical energy of a compressor. The shaft coupling mechanism of the motor of the invention is different from the traditional heat pump improvement technical structure; the motor for refrigerant decompression is adopted to replace the expansion valve in the common heat pump system, and the shaft coupling mechanism of the motor drives the shaft of the compressor to rotate while the motor rotates, thus reducing input of electrical energy of the compressor, avoiding great waste of the expansion valve, realizing energy recovery and greatly improving the energy efficiency ratio.
Description
The invention belongs to the heat pump industry field, relate to a kind of motor shaft coupling pressure energy recovering mechanism that improves Energy Efficiency Ratio greatly.
Background technology
The Energy Efficiency Ratio that improves heat pump is the key technology that improves heat pump efficiency, popularizes the heat pump use.Be tending towards ripe today in the refrigerant technical development, it then is the key that improves the heat pump Energy Efficiency Ratio that the mechanism of heat pump improves, and is the basis of improving the heat pump practicality and popularizing use.Heat pump will be used widely in many industry and civilian occasion efficiently.
Existing heat pump techniques, mechanism and principle basically identical, the main cause that efficient is not high is the waste of the energy, the pressure of the high pressure refrigerant of heat pump compressor electric energy conversion at present can be the most serious in the waste of expansion valve place, lose in vain and effectively do not utilized, the high pressure refrigerant just carries out the throttling step-down by expansion valve merely, and available energy loses in throttling process.At this situation, the motor shaft coupling pressure energy recovering mechanism that the present invention proposes can allow the high pressure refrigerant CD-ROM drive motor in decompression process after the release heat rotate, and the pressure that discharges can be fed back to compressor by means of coupling body, effectively the drive compression machine rotates, and reduces the electric power input of compressor.In theory, the pressure that the high pressure refrigerant has can come from and equal the compression energy consumption of low pressure refrigerant fully, consider the influence of factors such as this wherein rubs, the efficient of motor, shaft coupling efficient, energy loss accounts for about 20%, reclaiming 80% energy just can make power consumption of compressor drop to original 1/5th, thereby the Energy Efficiency Ratio that can make heat pump significantly brings up to 15～25 by present 3～5, and this will greatly promote promoting the use of of heat pump.
Summary of the invention
The objective of the invention is: provide a kind of simple in structure, be easy to realize, easy to maintenance, the novel heat pump mechanism that can improve Energy Efficiency Ratio greatly.
Technical scheme of the present invention is: motor shaft coupling pressure energy recovering mechanism has been done less change on the basis of existing heat pump basic structure, adopt novel refrigerant step-down motor to replace existing expansion valve, by coupling body the main shaft of refrigerant step-down motor and compressor is coupled together simultaneously, when motor is realized the coolant throttle step-down, the energy that the refrigerant step-down is discharged passes to compressor by coupling body, drive compression machine main shaft rotates the compression and low pressure refrigerant, has reduced the needed electric weight input of compressor itself.
The high-temperature low-pressure refrigerant that has absorbed heat enters compressor 4, the compressed refrigerant that becomes HTHP, the HTHP refrigerant enters heat release heat exchanger 1, release heat subsequently, isobaric cooling, liquefy through refrigerant fluid reservoir 2, enters motor 3, in motor 3, high pressure refrigerant isothermal expansion releases energy, and energy promotes the rotation of motor 3, and by shaft coupling 5, energy is passed to compressor 4, its continuation is compressed the low pressure refrigerant that newly enters, the refrigerant in the motor 3 flows into heat absorption heat exchanger 6 subsequently, absorb heat, the isobaric intensification, volumetric expansion becomes the gaseous state low pressure refrigerant, and then enter compressor 4, finish circulation, repeat above process, can realize that the transfer of energy is finished refrigeration and heated process.Motor shaft coupling pressure energy recovering mechanism comprises: heat release heat exchanger 1, fluid reservoir 2, motor 3, compressor 4, shaft coupling 5, heat absorption heat exchanger 6.(referring to Fig. 1)
1, realizes the recovery of pressure energy, improve Energy Efficiency Ratio greatly, it is characterized in that: refrigerant decompression motor is when the replacement expansion valve is realized the throttling hypotensive effect to refrigerant, can can pass to compressor to the pressure that refrigerant discharges by coupling body, the drive compression machine rotates, thereby reduced the input of the required electric energy of compressor itself.
2, simple in structure, be easy to realize, it is characterized in that: this invention has been done less change on the basis of existing heat pump structure, select for use suitable step-down motor to replace the expenditure and pressure effect of conventional expanded valve dexterously, structure by shaft coupling couples together the main shaft of motor and compressor simultaneously, realizes the recovery of pressure energy, and this structure is easy to realize, easy to maintenance, the reliability height.
Advantage of the present invention is: the difference of new technology and conventional art maximum is that there is the energy loss of expenditure and pressure in expansion valve place in the conventional art, and new technology is lost at this, the compression process that a kind of mechanism reclaims this energy and is used for low pressure refrigerant has effectively been proposed, thereby significantly reduce the compressor electric motor power consumption, the heat pump Energy Efficiency Ratio can be brought up to present Energy Efficiency Ratio 3～5 times.

The specific embodiment
Below the present invention is further illustrated.
The basic research of this structure is mainly reflected in the design of motor, the ratio that the design of shaft coupling and energy reclaim, in the course of the work, motor will be realized the effect of expansion valve, refrigerant becomes low pressure by high pressure, and the release of this pressure energy simultaneously drives motor, passes through the main shaft of shaft coupling drive compression machine again.In theory, energy comes from compressor work W at first, has reduced to W η by motor
Motor,, reduce to W η again by shaft coupling
Motorη
Shaft coupling, system needs energy bigger when just having come into operation, and after the system for the treatment of reached and stablizes, the consumption of compressor reduced to W-W η
Motorη
Shaft coupling, at this moment, the Energy Efficiency Ratio of system is
