Description
Technical field
The invention belongs to the air conditioner refrigerating technical field, be specifically related to a kind of refrigeration system and method for using thereof.
Background technology
At present, kind of refrigeration cycle technology is main to adopt the contrary circulation in Kano, decide entropy compression, the condensation of cold-producing medium isothermal and refrigerant liquid by cold-producing medium isothermal evaporation, refrigerant vapour and decides four cyclic processes of entropy expansion and constitute.Correspondingly, operation of air conditioning systems mainly is made up of evaporimeter, compressor, condenser, four parts of capillary expansion valve.Present Refrigeration Technique mainly is to be that the low-temperature heat source of T1 is transported to the high temperature heat source that temperature is T2 with heat from temperature, promptly from low-temperature receiver heat source carrying heat, is commonly called as " heat pump ".
For indoor refrigeration in summer, evaporimeter is arranged on indoor, and condenser is arranged on outdoor; Indoor temperature is lower than outdoor, and room air is a low-temperature receiver, and outdoor air is a thermal source; Isothermal evaporation after cold-producing medium in the evaporimeter and the room air heat exchange; Isothermal condensation in the condenser outside the compressor compresses refrigerant vapour inlet chamber; The heat transferred outdoor air that cold-producing medium carries in the condensation process, cold-producing medium are accomplished to decide to get back to after entropy expands in the capillary expansion valve and are repeated above-mentioned circulation in the evaporimeter.
For air conditioner for both cooling and heating, be used for refrigeration in summer, winter heating; From forming structure, it is compared with the air-conditioning that only has refrigeration, also is equipped with a cross valve.Summer, evaporimeter was arranged on indoor when freezing, and condenser is arranged on outdoor, and its action principle is the same.But during winter heating, because indoor temperature is higher than outdoorly, room air is a thermal source, and outdoor air is a low-temperature receiver; At this moment need be under the transformation of cross valve, realize the conversion that the position is set of evaporimeter and condenser, being arranged on outdoor is evaporimeter, being arranged on indoor is condenser; Isothermal evaporation after cold-producing medium in the evaporimeter and the outdoor air heat exchange; Isothermal condensation in the condenser in the compressor compresses refrigerant vapour inlet chamber; The heat transferred room air that cold-producing medium carries in the condensation process, cold-producing medium are accomplished to decide to get back to after entropy expands in the capillary expansion valve and are repeated above-mentioned circulation in the evaporimeter.
It is thus clear that no matter present kind of refrigeration cycle technology is in refrigeration or heats that evaporimeter all is arranged on to be needed to absorb in the environment of heat, promptly in the low-temperature receiver environment, has so just formed the mode of operation of evaporimeter and low-temperature receiver heat exchange, condenser and thermal source heat exchange.In above-mentioned refrigeration with heat in the circulation, the general cold-producing medium that adopts is a freon, according to measuring and calculating; In the air-conditioning of freon,, make that the coefficient of refrigerating performance of kind of refrigeration cycle is low because the latent heat of vaporization of freon is little as cold-producing medium; That is to say, when compressor consumes a particular energy, can be less relatively from the heat of low-temperature receiver carrying through cold-producing medium; So carry at needs under the prerequisite of a certain amount of heat, just need the above-mentioned more frequently particular energy of the corresponding consumption of compressor, promptly overall power consumption increases.
In order to solve the problems of the technologies described above, Chinese patent document CN201706615U discloses a kind of low energy consumption air-conditioning, and it is made up of evaporimeter and piston type compressed pump and condenser.Low energy consumption air-conditioning described in this technology is compared with traditional air conditioner, and its principle is identical with working procedure basically, just adopts water as cold-producing medium; Because glassware for drinking water has the very large latent heat of vaporization; Be maximum in known all materials, per kilogram is about 2400 kilojoules, and the latent heat of vaporization per kilogram of most of cold-producing mediums has only hundreds of kilojoules; Mean that ability that water vapour carries heat is several times as much as other cold-producing medium; That is to say to make water make that as cold-producing medium the coefficient of refrigerating performance of kind of refrigeration cycle is high, so correspondingly when compressor consumed a particular energy, it was more relatively from the heat of low-temperature receiver carrying to pass through cold-producing medium; So carry at needs under the prerequisite of a certain amount of heat; Just need the less inferior above-mentioned particular energy of the corresponding consumption of compressor, for the refrigeration system of aforementioned use freon, its overall less energy intensive.
Therefore, adopt water minimum as the cold-producing medium energy consumption of air-conditioning system.
What above-mentioned technology was suitable for is from the situation of low-temperature heat source to high temperature heat source carrying heat, and in actual production process, like cigar mill, textile mills; Because the machine release heat is bigger, and often indoor temperature is higher than outdoor temperature far away, need this moment to be disposed to indoor heat outdoor in its factory; The evaporimeter that so just needs to absorb heat is arranged in the thermal source environment; Because the temperature T 1 of this thermal source environment is high than outdoor environment temperature T2, so its pressure P 1 can corresponding pressure P 2 greater than the outdoor cold source environment, like this in adopting prior art during the contrary EGR that circulates in Kano; Become refrigerant vapour behind the heat of the cold-producing medium absorption thermal source environment in the evaporimeter; But, only need utilize above-mentioned pressure reduction to promote compressor and rotate because steam pressure P1 greater than the pressure P 2 that gets into the cold-producing medium in the condenser, does work to refrigerant vapour so need not compressor this moment; Its pressure of cold-producing medium that obtains behind the condenser of flowing through still remains P2; But the cold-producing medium behind the condenser of flowing through wants to loop back evaporimeter when inner, need through being arranged on the capillary expansion valve between said condenser and the said evaporimeter, but also just because of P2 less than P1; So the capillary expansion valve can't loop back cold-producing medium in the evaporimeter, make the contrary circulation in basic Kano to carry out.
But, if under above-mentioned specific environment, realize normally carrying out of the contrary circulation in Kano, so just need reactivate compressor work, so just make that the lower P2 of pressure can obtain the pressure value greater than P1 after compressor work originally; Cold-producing medium just can waltz through the capillary expansion valve and loops back in the evaporimeter like this.But in said process, compressor is in case acting will consumes energy, can promote compressor in the time of so just can't embodying pressure P 1 greater than P2 voluntarily and rotate and need not the advantage of using compressor to do work.
Summary of the invention
For this reason; Technical problem to be solved by this invention is to be higher than outdoor environment temperature and need be from the indoor environment release heat when outdoor at indoor environment temperature in the prior art; If adopt the EGR of the contrary circulation in Kano; And utilize P1 to need not compressor work greater than the advantage of P2, then the contrary circulation in Kano can't realize; When adopting compressor to do work to realize that the contrary circulation in Kano is carried out smoothly; Because compressor work consumes energy; Make energy consumption increase; And then provide a kind of and be higher than outdoor environment temperature and need be from the indoor environment temperature release heat under outdoor operating mode above-mentioned at indoor environment temperature, promptly need not to utilize compressor work and can realize equally the indoor environment heat is discharged into the energy circulation system in the outdoor environment.
