Abstract
The present invention utilizes solar energy or other thermal source to certain regulation space or the regional device that carries out refrigeration or cooling.When refrigerant obtains heat energy from the thermal-arrest unit after, just can produce two not closed circuits of same-action by apparatus of the present invention, one of them loop is to make refrigerant reduce temperature in this regulation space or the zone by the heat that the capillary section flow evaporator absorbs certain regulation space or zone.And another loop is the refrigerant cycle that helps after evaporation.
Description
The present invention utilizes solar energy or other thermal source to the space of certain regulation or cool off in the zone or the device of refrigeration.
The inventive system comprises:
A) be used to add hot refrigerant and make inner thermal-arrest unit (2) and the heat-generating units (8) that produces certain pressure of apparatus of the present invention.The surperficial coating black in thermal-arrest unit (2), its heat energy source is in heat-generating units (8).If our obtained thermal source is from solar energy then heat-generating units (8) is the solar energy Accumulated Heat Units.If our obtained thermal source is the energy of other form then heat-generating units (8) is a heat production device.
B) be installed in, provide, reclaim the pressure vessel (1) of refrigerant (7) for apparatus of the present invention, in device, play cushioning effect.
C) be used for heat-sink unit (3) that refrigerant is cooled off.
D) be used for refrigerant (7) is carried out the capillary (9) and the evaporation element (4) of throttling and evaporation.
E) be used for extracting the refrigerant (7) that evaporation element (4) is evaporated and the extracting unit (5) that is provided with.
F) for the refrigerant after avoiding evaporating from evaporation element (4) to the process of extracting unit (5) dew outside pipeline not, going up at this root pipeline (6) must insulation.
G) pressure vessel (1) and thermal-arrest unit (2) and extracting unit (5) are connected into a specific loop, see Fig. 1.
H) with pressure vessel (1), thermal-arrest unit (2), heat-sink unit (3), capillary (9), evaporation element (4), cold insulation pipe (6), and extracting unit (5) form another particular loop, see Fig. 1.
I) be used for refrigeration and be encapsulated in pressure vessel (1), normal temperature and pressure is liquid refrigerant (7) down.
J) be used to connect the necessary pipeline in above-mentioned each unit.
By device of the present invention, under the situation that has sunshine or other thermal source to exist, can continuously cool off or refrigeration the space of certain regulation.
Refrigerant (7) can select for use boiling point at 50 C-80 C, and freezing point is below-20 C, and saturated vapor is pressed between the 8-15 KGF/CM2 when 100 C-150 C, and fluid density differs bigger any liquid [hereinafter to be referred as refrigerant (7)].
Refrigerant (7) is encapsulated in the pressure vessel (1) at normal temperatures and pressures, connects pressure vessel (1) and thermal-arrest unit (2) with pipeline.Be used for carrying out its origin of heat of thermal-arrest unit (2) of heat exchange in heat-generating units (8) with refrigerant (7).When we utilized solar energy as thermal source, heat-generating units (8) was a solar-energy light collector.Heat-generating units (8) is a kind of heat production device if we utilize other thermal source.Refrigerant in the thermal-arrest unit (7) is heated the pressure that produces 8-15 KGF/CM2, because pressure vessel (1) thermal-arrest unit (2) and extracting unit (5) have been formed a specific loop, again because the principle of the thermal siphon refrigerant (7) after some is heated circulates generation in this loop.When refrigerant (7) at extracting unit (5) through out-of-date, in extracting unit (5), just produced a negative pressure region.Another heated refrigerant of part (7) then flows in another particular loop of being made up of pressure vessel (1), heat build-up unit (2), heat-sink unit (3), capillary (9), evaporimeter (4), cold insulation pipeline (6) and extracting unit (5).The refrigerant (7) of heat is cooled when being flowed through heat-sink unit (3) by the refrigerant (7) after thermal-arrest unit (2) heating, cooled refrigerant (7) absorbs the heat in certain regulation space through capillary (9) and evaporation element (4) throttling and evaporation, certain regulation space temperature is descended.Yet the refrigerant (7) after evaporation element (4) throttling and evaporation is delivered in the extracting unit (5) through cold insulation pipe (6).Because the effect in above-mentioned first loop causes and produced negative pressure in the extracting unit (5) and just refrigerant (7) is withdrawn in the container (1), it is higher to return refrigerant (7) temperature of returning in the container (1) in relative second loop of refrigerant (7) in the container (1) in above-mentioned first loop.Mixing the pressure that makes liquid level top in the container (1) when the refrigerant in these two different circuits returns container (1) mutually reduces (instantaneous) and impels first loop to quicken circulation again.And the acceleration in first loop circulation just can make and constantly produces negative pressure in the extracting unit (5), and this has promoted the throttling and evaporation and the circulation of refrigerant in second loop again.Go round and begin again like this as long as under the situation that the sun or other thermal source are arranged, just can continuously cool off or refrigeration to certain regulation space.
We specify with regard to the present invention below in conjunction with Fig. 2 for the ease of implementing the present invention: (being example to utilize solar device only here).
When we select for use methyl alcohol to make refrigerant, since the vapour pressure of methyl alcohol reaches the required heating-up temperature of 14KGF/CM2 be 140 C thus by general thermal-arrest unit as way such as outer blacking is to reach this temperature in the thermal-arrest unit, must focus on sunshine, and focus is dropped on the heat collecting sheet (2), yet the sun from morning to night be indefinite motion so the solar energy focusing device (8) here is preferably with solar tracking system.Make methyl alcohol be heated to 140 C through heat collecting sheet (2) heating and at this moment in system of the present invention, just produced pressure about 14 KGF/CM2.It is divided into two strands, one removes Venturi tube (5) and pressure vessel (1), because the effect of thermal siphon makes methyl alcohol constantly circulate and form a negative pressure region in the particular loop of being made up of pressure vessel (1), thermal-arrest unit (2), Venturi tube (5) in Venturi tube (5).Yet the heated methyl alcohol of another strand then is cooled to highly pressurised liquid methyl alcohol through the fin heat radiation, and throttling expansion becomes gaseous methanol with evaporimeter (4) through capillary (9) then.Methyl alcohol just absorbs the heat in certain regulation space in this course, this regulation space temperature is descended, and reach refrigeration or cooling purpose.Gaseous methanol after the evaporation is withdrawn in the container (1) by Venturi tube (5) through cold insulation pipe (6).Meanwhile in Venturi tube (5), the recycle methanol of two bursts of different temperatures is mixed mutually and is got back to the temperature that makes in the container (1) in the container (1) also descend (instantaneous).This impels the circulation of methyl alcohol in above-mentioned first loop so constantly to go round and begin again, and just constantly refrigeration or cooling is carried out in certain regulation space having under the situation of sunshine.
