Before describing the embodiments in more detail, it should be understood that and the invention is not restricted to detailed construction in the application hereafter or described in accompanying drawing or arrangement of elements.The present invention can be the embodiment that alternate manner realizes.And, should be appreciated that wording used herein and term are only used as to describe purposes, should being construed as limiting property not explain.Similar wording meant and comprised item listed thereafter, its equivalent and other additional things " comprising " used herein, " comprising ", " having " etc.Particularly, when describing " certain element ", the quantity that the present invention does not limit this element is one, also can comprise multiple.
Fig. 1 is the rough schematic view of air-conditioning power generation all-in-one machine.As shown in Figure 1, described air-conditioning power generation all-in-one machine comprises compressor 10, turbo-expander 12, magneto 14 and rotating shaft 16.Wherein, compressor 10 and rotating shaft 16 be fixedly connected with coaxially with rotating shaft 16 coaxial rotating, turbo-expander 12 and rotating shaft 16 be fixedly connected with coaxially with rotating shaft 16 coaxial rotating.Magneto 14 is connected with rotating shaft 16.Magneto 14 has two kinds of mode of operations: electric motor mode and generator mode.When being used as air-conditioning, magneto 14 works in a motor mode; When for generating electricity, magneto 14 works in the generator mode.
Described air-conditioning power generation all-in-one machine also comprises First Heat Exchanger 18, fluid reservoir 20 and evaporimeter 22, First Heat Exchanger 18 is connected with fluid reservoir 20 and the two is connected between compressor 10 and turbo-expander 12, and evaporimeter 22 is connected between compressor 10 and turbo-expander 12.
Compressor 10 comprises suction port of compressor 24 and compressor outlet 26, turbo-expander 12 comprises expander inlet 28 and expander outlet 30, First Heat Exchanger 18 comprises First Heat Exchanger entrance 32 and First Heat Exchanger outlet 34, and fluid reservoir 20 comprises fluid reservoir entrance 36 and fluid reservoir outlet 38.Wherein, First Heat Exchanger entrance 32 and compressor outlet 26 fluid communication, fluid reservoir entrance 36 and First Heat Exchanger export 34 fluid communication, fluid reservoir outlet 38 and expander inlet 28 fluid communication.
Different according to the purposes of air-conditioning power generation all-in-one machine, expander outlet 30 working medium out gets back to compressor 10 through different passages.Specifically, the first working medium backward channel 40 and the second working medium backward channel 42 is connected to suction port of compressor 24 and turbo-expander exports between 30.The exit of turbo-expander 12 arranges these two working medium backward channels, and to make, the working medium that exports from described turbo-expander 12 can optionally via the first working medium backward channel 40 and the second working medium backward channel 42, one of them be back to compressor 10.In an illustrated embodiment, expander outlet 30 and arrange a valve 52 between the first working medium backward channel 40 and the second working medium backward channel 42, in order to the passage selecting the first working medium backward channel 40 or the second working medium backward channel 42 to return compressor 10 as the working medium exported by turbo-expander 12.
Evaporimeter 22 is arranged on the first working medium backward channel 40.During as idle call, select the first working medium backward channel 40, working medium absorbs the heat of room air and evaporates in evaporimeter 22, thus reduces indoor temperature.
Second working medium backward channel 42 is provided with the second heat exchanger 44.During as generator, select the second working medium backward channel 42.During generating, magneto 14 works in the generator mode, and turbo-expander 12 is by the generating of rotating shaft 16 drive electrical generators.The Temperature of Working that turbo-expander 12 exports, generally at about 80 degree, could be got back to compressor 10 further after needing to utilize heat exchanger heat release cooling and carry out next circulation.In an illustrated embodiment, described second heat exchanger 44 is between compressor outlet 26 and First Heat Exchanger entrance 32, make when the second working medium backward channel 42 is returned compressor 10 by selection in order to the working medium exported by turbo-expander 12, the working medium that turbo-expander 12 exports and the working medium that compressor 10 exports carry out heat exchange in the second heat exchanger 44.Specifically, the Temperature of Working (about 80 degree) exported from turbo-expander 12 is higher than the Temperature of Working (about 40 degree) exported from compressor 10, therefore, the working medium exported from turbo-expander 12 in the second heat exchanger 44 can carry out preheating to the working medium exported from compressor 10, improves the efficiency of system.Certainly, in other embodiments, the second heat exchanger 44 also can be positioned at other position, and not between compressor outlet 26 and First Heat Exchanger entrance 32.
Because compressor 10 has a definite limitation for the Temperature of Working entered, can not be too high, therefore, second working medium backward channel 42 is also provided with the 3rd heat exchanger 54,3rd heat exchanger 54 is connected between suction port of compressor 24 and the second heat exchanger 44, to lower the temperature further to reach the temperature requirement entering compressor 10 to the working medium in the second working medium backward channel 42.
In the present embodiment, magneto 14 is arranged between compressor 10 and turbo-expander 12.In other embodiments, generator 14 also can be placed in any suitable position, as long as can drive shaft 16 or driven by rotating shaft 16.Magneto 14 comprises p-m rotor 46 and the stator 48 around p-m rotor 46, and p-m rotor 46 comprises the permanent magnet being fixed on rotating shaft 16 periphery.
When described air-conditioning power generation all-in-one machine uses as air-conditioning, First Heat Exchanger 18 uses as condenser, and magneto 14 is as motor driven compressor 10.Working medium enters First Heat Exchanger 18 heat release as condenser after compressor 10 compresses, working medium becomes liquid and enters fluid reservoir 20, in the process, fluid reservoir 20 is in order to regulate the flow of whole pipeline working medium, when the working medium circulation in refrigeration system is very fast, fluid reservoir 20 can provide the working medium of q.s.Then working medium enters turbo-expander 12 expansion work from fluid reservoir 20, turbo-expander 12 absorbs the expansion work of working medium and rotates, the rotation of turbo-expander 12 drives rotating shaft 16 rotate and then drive compressor 10 to operate, and therefore reduces the electric energy needed for magneto 14, reaches energy-saving effect.That is, in the present embodiment, the power part driving compressor 10 to rotate comes from magneto 14, and some comes from the expansion work that turbo-expander 12 absorbs, the namely rotational kinetic energy of turbo-expander 16, therefore saves the electric energy required for magneto 14.
Working medium enters the first working medium backward channel 40 after turbo-expander 12 puffing, when evaporator 22, working medium heat absorption reduce ambient air temperature, then working medium through the first working medium backward channel 40 be back to compressor 10 carry out next circulation.Be understandable that, when described second heat exchanger 44 is between compressor outlet 26 and First Heat Exchanger entrance 32, when using as air-conditioning, the second heat exchanger 44 does not carry out heat exchange process to the working medium that compressor 10 exports.When temperature is cooled to predetermined temperature, all break-ofves of compressor and turbo-expander.
When described air-conditioning power generation all-in-one machine is for generating electricity, magneto 14 works in the generator mode.Now, First Heat Exchanger 18 receives an external heat source (such as industrial exhaust heat) and heats the working medium flowed through, the working medium of HTHP enters turbo-expander 12 and drives its turbine to rotate, turbine rotation drives rotating shaft 16 to rotate and then drive generator 14 to send a large amount of electric energy and uses for user, and turbo-expander 12 also drives compressor 10 to operate simultaneously.The working medium exported from turbo-expander 12 is back to compressor 10 via the second working medium backward channel 42, because the Temperature of Working exported from turbo-expander 12 is also higher, working medium is when the second heat exchanger 44, the Temperature of Working exported from compressor 10 is lower, the two carries out heat exchange, the Temperature of Working exported from compressor 10 raises, and can save the energy of next link external heat source.Through the Temperature of Working of the second heat exchanger still higher than compressor 10 inlet temperature requirements, therefore working medium continues to enter the temperature requirement that the 3rd heat exchanger 54 makes working medium reach to enter compressor 10, and then working medium returns compressor 10 and again circulates.Certainly, if when the second heat exchanger 44 is not between compressor outlet 26 and First Heat Exchanger entrance 32, then can not the working medium that compressor 10 exports be preheated.
In the above-described embodiments, under magneto 14 is operated in motor and generator mode according to different purposes, a motor is therefore used to complete two kinds of purposes.As the embodiment introduced below, this air-conditioning power generation all-in-one machine also can use an engine and a generator.
Fig. 2 is the rough schematic view of another embodiment of air-conditioning power generation all-in-one machine.Air-conditioning power generation all-in-one machine in the present embodiment and previous embodiment difference are, use a motor be connected with compressor 10 56 and a generator 58 be connected with turbo-expander 12 in the present embodiment.When being used as air-conditioning system, motor 56 starts to drive compressor 10.When being used as electricity generation system, generator 58 is driven to generate electricity by described turbo-expander 12.
In sum, the invention provides a kind of air-conditioning power generation all-in-one machine.When described air-conditioning power generation all-in-one machine uses as air-conditioning, compressor is driven by motor, and described First Heat Exchanger is as condenser, and the working medium that described turbo-expander exports is back to described compressor via described first working medium backward channel; When for generating electricity, described First Heat Exchanger receives an external heat source and heats the working medium flowed through, the working medium that described turbo-expander exports is back to described compressor via described second working medium backward channel, described second heat exchanger is lowered the temperature to the working medium that described turbo-expander exports, and described turbine expansion machine driving generator generates electricity.This device, on the basis not affecting air-conditioning normal operation, utilizes the standby time of air-conditioning, makes full use of each electrical components in air-conditioner and refrigeration unit thereof, plays diversification effect, the refrigeration unit system of air-conditioning is become electricity generation system.Therefore, same set of device, both can work as air-conditioning and use, and can work as again generator and use, effectively improve the utilization rate of equipment.
Concept described herein may be embodied to other form when not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary instead of restrictive.Therefore, scope of the present invention is by appended claim, instead of determines according to these descriptions before.Any change in the letter and equivalency range of claim all should belong to the scope of these claims.
