Background technology
Thermodynamic cycle (thermodynamicalcycle) refers to that operation material returns to its this overall process gone round and begun again of original state after the change of a series of states, also known as cyclic process, is called for short circulation.Such as during heat engine work, operation material therein (steam in steam engine) is namely changed by a series of state, a part from high temperature heat source draw heat is changed into mechanical power, and by a part of waste heat discharge to low-temperature heat source, and operation material itself is returned to original state.Owing to heat engine constantly to work, operation material therein is necessary for carrying out again and again this cyclic process, with constantly from thermal source draw heat externally work done.
Thermodynamic cycle utilizes the temperature difference between high temperature heat source and low-temperature heat source to produce mechanical power, and the efficiency of acting depends on the temperature of high temperature heat source and low-temperature heat source.Thermodynamic cycle acting so far passes to the energy of low-temperature heat source, and major part can only be dispersed in environment and cannot utilize, and causes the thermal efficiency low.Three thermals source of research, four thermals source are all pump heat or refrigeration at present, seldom relate to acting, and energy Flow is all unidirectional opening, it is impossible to recycle.In order to improve the thermal efficiency of entirety, method can only be looked for from the environment of low-temperature heat source, after finding the cryogenic energy absorbing thermodynamic cycle, promote the method becoming high temperature energy.Man-made environment's a kind of method thus, environment working medium as low-temperature heat source (realizes heat energy and media material that mechanical energy converts mutually is called working medium, rely on its state change in heat engine could obtain merit as expanded, and do work and could transmit heat by working medium), after absorbing the heat energy lifting energy of acting working medium, make environment working medium become again low-temperature heat source by some mode, thus can make energy recycling, improve the thermal efficiency.
Summary of the invention
It is an object of the invention to provide a kind of thermodynamic cycle system being realized recycle heat by environment working medium, for solving the problem of utilization of energy rate variance in prior art.
For achieving the above object, the present invention provides following technical scheme:
The thermodynamic cycle system of recycle heat is realized by environment working medium, described system includes interconnective environment working substance system and thermodynamic cycle system, and described thermodynamic cycle system includes: sequentially circulate the cycle fluid vaporizer of connection, cycle fluid expansion gear, cycle fluid condenser and cycle fluid pump.
In order to reclaim the energy passing to low-temperature heat source in thermodynamic cyclic process, and to promote into can be senior thermal source required for thermodynamic cycle, the present invention is by providing an artificial environment, by the change of environment working medium state, to thermodynamic cycle system heat absorption or heat release.Rudimentary energy can not be transformed into senior energy without foundation, so introducing external heat source.External heat source acts on man-made environment, makes the state of man-made environment change, and reaches the purpose of heat absorption and heat release.Described external heat source is high temperature heat source or the combination of multiple low-temperature heat source or high temperature heat source and multiple low-temperature heat source.
This low-temperature heat source can be cooling water, the low-temperature heat quantity actively extracted from air or rivers,lakes and seas, can also be the low temperature heat energy extracted from underground heat or solar heat.These low temperature heat energies are incorporated in man-made environment, and are promoted to high temperature heat with the change of environment working medium state, are then passed in thermodynamic cycle system.
By this method, summer air-conditioning room also can become a low-temperature heat source；Some Area during Summer outdoor temperature is too high, and the air in these places can also become a low-temperature heat source；Some lake and marine site can because water temperature height cause red tide/green tide to pollute, although now as technical reason, it is impossible to remove Organic substance excessive in water body, reduce the effective ways that water temperature is also containment algae excessive propagation, so these water bodys are also low-temperature heat sources.
The working medium of thermodynamic cycle system can be water, it is also possible to is low boiling organic working medium, it is possible to generating can also be done work and be driven other device；Environment working substance system can be changed between low temperature state and the condition of high temperature, the main absorption cycle working medium heat of low temperature state makes cycle fluid complete phase transformation, the main phase-change energy that thermodynamic cycle system is provided of heat that environment working substance system absorbs and discharges, the energy that acting needs is provided by external heat source, so the present invention is more suitable for low boiling organic working medium blood circulation.Environment working medium is divided into according to the conversion regime of energy: 1) environment working medium realizes the conversion between low temperature state and the condition of high temperature by phase transformation；2) environment working medium remains gaseous state, absorbs simply by variations in temperature and discharges heat；3) environment working medium is liquid, by changing the vapour pressure of liquid environment working medium so as to vapor-liquid separation；Or by the 3rd working medium of environment working substance steam can be absorbed, by changing the state of the 3rd working medium, the 3rd working medium is made to absorb conversion between the state that environment working substance steam amount is many and few, absorbing the state that environment working substance steam is many, absorb this environment working substance steam makes the temperature of liquid environment working medium reduce simultaneously, absorbing the state release environment working substance steam that environment working substance steam is few, this steam is become the steam of high level simultaneously.
