Description
Technical field
The present invention relates to a kind of self-driven hot compression formula heat pump refrigerating method and device thereof, belong to heat pump refrigerating technical field.
Background technology
Conventional heat pump refrigerating method has steam compression heat pump refrigeration, absorption heat pump refrigeration, adsorption type heat pump refrigeration etc., wherein especially general with steam compression heat pump refrigeration, absorption heat pump refrigeration application.
Steam compression heat pump refrigeration thermodynamic coefficient is higher, but must consume more electric energy as drive energy.Hot compression heat pump refrigerating (absorption refrigeration or absorption type refrigerating) can utilize low grade heat energy to drive, the electric energy consuming is less, but thermodynamic coefficient is lower, in the time not having used heat to utilize, accounting for how many advantages unlike steam compression type refrigeration economically, is not to have used heat can supply to utilize everywhere in practice.
Summary of the invention
The object of this invention is to provide a kind of hot compression formula heat pump refrigerating method and device of high-efficiency and economic.The problem solving is: look for more economical, thermocompressor driving method and device more easily, improve the thermodynamic coefficient of hot pressing compression type refrigerating.
The technical solution used in the present invention: existing hot compression formula heat pump refrigerating is looped to improvement, reclaim refrigerant vapour condensation heat as driving heat source.Select suitable working medium (or working medium to) as the working medium of hot compression heat pump refrigerating (working medium to), form hot compression formula heat pump refrigerating device by generator (adsorbent bed), vapour compression machine, expenditure and pressure valve, evaporimeter, absorber (or adsorbent bed) and connecting pipe etc.The middle compression refrigerant steam that adopts the generation (or desorb) of vapour compression machine to hot compression to produce compresses and is warming up to hot compression and heats required heat source temperature, high pressure refrigerant vapor after intensification heats for the generator (or adsorbent bed) to hot compression as thermal source, high temperature refrigerant steam is to generator (or adsorbent bed) heat release of hot compression, make the weak solution evaporation and concentration (or working medium desorb) of generator (or adsorbent bed), produce cold-producing medium middle pressure steam, high temperature refrigerant steam-condensation becomes refrigerant liquid simultaneously.Refrigerant liquid is through the decompression of expenditure and pressure valve, and evaporation endothermic in evaporimeter, provides low temperature environment, produces refrigerant vapour.
Also can form combined heat pump refrigerating plant by generator (adsorbent bed), condenser, expenditure and pressure valve, evaporimeter, absorber (or adsorbent bed), vapour pressure group machine etc.Combined heat pump refrigerating plant is by driving circulation and two circulations of heat pump refrigerating circulation to form.There are two kinds of implementations.A kind of is the driving circulation of recovering condensing heat, is also a heat pump refrigerating circulation in essence, by vapour compression machine, generator (or adsorbent bed), expenditure and pressure valve as condenser, form as the condenser of evaporimeter.Drive working substance steam driving heat source as generator (or adsorbent bed) after compressor pressurization compression, drive working substance steam to be condensed into driving worker quality liquid simultaneously, drive worker quality liquid through expenditure and pressure valve expenditure and pressure, enter the condenser as evaporimeter, drive worker quality liquid evaporation to produce and drive working substance steam, heat pump refrigerating working substance steam is condensed into heat pump refrigerating worker quality liquid simultaneously.Heat pump refrigerating circulation in this combined heat pump refrigerating plant is existing arbitrary hot compression formula heat pump refrigerating circulation.Another kind is the driving circulation that recovery absorption heat (or heat of adsorption) is made driving heat source, also be the circulation of heat pump refrigerating in essence, by vapour compression machine, generator (or adsorbent bed), expenditure and pressure valve as condenser, be formed by connecting as absorber (or adsorbent bed) and the pipeline of evaporimeter.Drive working substance steam driving heat source as generator (or adsorbent bed) after compressor pressurization compression, drive working substance steam to be condensed into driving worker quality liquid by generator (or adsorbent bed) simultaneously, drive worker quality liquid after choke valve expenditure and pressure, to enter the absorber (or adsorbent bed) as evaporimeter, drive worker quality liquid to absorb heat (or heat of adsorption) and flash to driving working substance steam, drive working substance steam to enter compressor pressurizes compression, start next circulation.
In absorption heat pump refrigeration, the low pressure refrigerant vapor that evaporimeter produces enters in absorber, the concentrated solution being absorbed in device absorbs, concentrated solution becomes weak solution, to environment heat release, weak solution pumps into solution heat exchanger through solution pump, in solution heat exchanger, carries out entering generator after heat exchange with the concentrated solution flowing back to absorber from generator, starts next circulation.
In adsorption type heat pump refrigeration, the refrigerant vapour that evaporimeter produces is adsorbed bed absorption in adsorbent bed, and working medium is adsorbed on adsorbent, to environment heat release, starts next circulation.
In absorption heat pump kind of refrigeration cycle, in the time that working medium is nearer to boiling point, between generator and vapour compression machine, set up rectifier, the working medium that generator is produced is carried out rectifying to mixed vapour, and high-purity refrigerant vapour of generation enters vapour compression machine again and compresses.
While making heat pump purposes, the low pressure refrigerant vapor compression of pressurizeing that adopts compressor to produce evaporation, can improve absorption (or absorption) pressure of absorber (or adsorbent bed), thereby improve absorption (or absorption) temperature of absorber (or adsorbent bed), to improve heat supply temperature.
Effect of the present invention: the present invention has recycled the condensation latent heat of refrigerant vapour as driving heat source, do not need high temperature driven thermal source, also reduce the cooling-water consumption of condensation process, only needed the condensation latent heat that consumes a small amount of utilization of power refrigerant vapour to produce driving heat source.Generally provide the refrigerating capacity of 1000KW, the electric energy approximately 30 to 70KW that compressor consumes; In addition, although increased the vapour compression machine of compression process, in generator, complete simultaneously and occur and condensation process, reduced special condenser.The present invention, compared with traditional vapor compression formula heat pump refrigerating method, economizes consumption and saves more than 80%.Compared with a general absorption heat pump refrigerating method, do not need middle temperature low-grade heat source, do not need consume fuel yet, realize self-drivenly, even without the place of used heat, only need to consume the electric energy of minute quantity, also can apply, energy-saving effect is remarkable.
