Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
To the utility model embodiment, elaborate again by above-mentioned accompanying drawing below.
As shown in Figure 1,1. evaporimeter, 2. reservoir, 3. compressor, 4. condenser, 5. capillary.
The high low temperature multistage conversion equipment of medium energy, mainly refer to a kind of conversion equipment that absorbs or release energy from medium energy, it by two groups or more the circulatory system successively combined serial form, and by medium in each circulatory system flow to form the larger temperature difference, and this temperature difference to be utilized, the present embodiment can adopt 6 groups of circulatory systems of connecting successively.
Each described circulatory system includes evaporimeter 1, reservoir 2, compressor 3, condenser 4 and capillary 5, and this evaporimeter 1, reservoir 2, compressor 3, condenser 4 and capillary 5 are done circulation successively through pipeline and be connected; Described evaporimeter 1 has evaporation coil, by this evaporation coil, can be realized liquid evaporation and be absorbed heat; Described reservoir 2 stores for medium and the impurity of filter medium, and supplements after dielectric loss; Described compressor 3 is as the power source of the circulatory system, and drive medium flows in a whole set of circulatory system; Described condenser 4 has condenser coil, can realize gas condense and release heat by this condenser coil; Described capillary 5 is for the flow equilibrium of medium in the circulatory system.
In 6 groups of described circulatory systems of connecting successively, the condenser 4 of the last group of circulatory system of every two adjacent groups circulatory system must with the evaporimeter 1 of rear one group of circulatory system mutually near, and the evaporation coil of the condenser coil of condenser 4 and evaporimeter 1 intermeshes overlapping, mainly play the effect of Rapid Thermal exchange.Therefore, at normal temperatures, the evaporimeter 1 of its initiating terminal circulatory system just can absorb maximum heat to 6 groups of circulatory systems after series connection successively, thus generally can be directly as low-temperature receiver use, as the low-temperature receiver as Cold storage in the refrigerator etc.; And the condenser 4 of the clearing end circulatory system just can discharge maximum heat, thus generally can be directly as thermal source, use, as the thermal source of boiler heating etc.; Simultaneously, between the evaporimeter 1 of the initiating terminal circulatory system and the condenser 4 of the clearing end circulatory system, can produce the temperature difference, this temperature difference is far longer than the temperature difference between evaporimeter and condenser in single cover circulatory system, thus by this larger thermal gradient energy, carry out multiple application, as generating etc.
Described be added on 6 groups of media in the circulatory system of connecting successively and also must to higher boiling, carry out correspondence according to low boiling, thus according to 6 groups of circulatory systems the order from initiating terminal to clearing end the corresponding medium adding be respectively carbon dioxide, ammonia, freon R-22 HCFC cold-producing medium, acetone, water and Dowtherm.This order of addition can not be chaotic, otherwise cannot realize the work of multistage conversion equipment.Certainly, if only select 2 groups of circulatory systems or be greater than 2 groups of circulatory systems, its medium order of addition also must be carried out correspondence to higher boiling according to this low boiling, and the medium boiling point in rear one group of circulatory system must be higher than the medium boiling point in the last group of circulatory system.The selection of medium mainly utilizes the difference of the saturated vapor pressure of material, the needs of selecting corresponding medium to reach required refrigeration or heat; And medium from low temperature to high temperature order is selected, also need to meet saturated vapor and force down the rule that saturated vapor pressure is high, utilize the higher principle of the larger heat exchanger effectiveness of the temperature difference, just can make more efficient refrigeration plant or heating equipment.
Medium can high low temperature multistage conversion equipment operation principle take the two adjacent groups circulatory system and be elaborated as example, its course of work is with shown in Fig. 1 arrow: the compressor 3 startup work in the initiating terminal circulatory system, by the liquid medium of gaseous medium boil down to HTHP and enter in the condenser 4 of the initiating terminal circulatory system, because gaseous medium is condensed into liquid medium, thereby at condenser periphery, discharge a large amount of heats, and make condenser 4 temperature higher than periphery normal temperature; And the liquid medium of HTHP arrives evaporimeter 1 again through capillary 5 again, while arriving evaporimeter due to liquid medium through capillary, pressure reduces suddenly, therefore liquid medium re-vaporization is cryogenic gaseous medium, thereby at evaporimeter 1 periphery, absorb a large amount of heats, and make evaporator temperature lower than periphery normal temperature; When gaseous medium flows back to compressor 3 again, become again the liquid medium of HTHP, gaseous state and liquid conversion by this cover circulatory system medium can realize in low temperature, condenser 4 and realize high temperature in evaporimeter 1.And evaporimeter 1 in the clearing end circulatory system due to the initiating terminal circulatory system in condenser 4 intermesh overlapping, therefore in the clearing end circulatory system 1 calorific requirement of evaporimeter directly the condenser in the initiating terminal circulatory system 4 provide, it compares the heat absorption under normal temperature, can form heat exchange faster between the two, therefore, operation principle with reference to initiating terminal circulatory system medium, and the raising of the heat exchanger effectiveness of the combination termination end circulatory system, the condenser 4 in this clearing end circulatory system just can discharge higher heat.In like manner, as long as series connection successively more, organize the circulatory system and arrive the corresponding medium that adds of high boiling order according to low boiling, just can in the evaporimeter of the initiating terminal circulatory system, obtain lower temperature, in the condenser of the clearing end circulatory system, obtain higher temperature.
The utility model is actually the device that a kind of multilevel heat source absorbs or discharges, it is the working media through compressor work and selection different temperatures interval by thermal source, thereby make temperature be improved step by step or reduce, finally reach temperature required, greatly improved the utilization ratio of medium energy, it can be widely used in the efficient application on air-conditioning, also can be used for air energy heater, it is not subject to externally temperature influence, no matter how low ambient temperature is, as long as there is air can be family, provide hot water or thermal source, also can be used for high-temperature boiler, as long as increase circulatory system quantity, just can utilize air heat energy to reach higher temperature, or provide more efficient refrigeration plant for freezing enterprise.
