Abstract
The utility model relates to a steam jet type refrigerator for low pressure refrigerating system is equipped with low pressure freon working medium in its steam pocket to by the heater heating, the steam pocket upper port through the constant pressure ware simultaneously with sprayer import and backflow sprayer import intercommunication, backflow sprayer's export is through the other upper port intercommunication of check valve with the steam pocket, backflow sprayer's suction inlet and the export intercommunication of condenser. The utility model discloses the noise is little, and injection efficiency is high, and overall structure is simple, and the operation is reliable.
Description
The utility model relates to a kind of steam jet refrigerator that is used for the low pressure refrigeration system.
Existing steam jet refrigerator is working medium with water, and equipment itself does not have boiler, and its power steam is supplied with by boiler or steam turbine etc., though it is simple that it has a moving component, motion is reliable, advantage such as makes and easy to maintenance, but it can evaporate under 5 ℃ of-15 ℃ of conditions for making water, then need very high vacuum, cause the exit velocity of nozzle high, considerably beyond velocity of sound, so its noise is very big, defectives such as it also exists mixing ratio very little simultaneously, and ejection efficiency is low, and range of application is little.
The purpose of this utility model is exactly in order to address the above problem, and a kind of ejection efficiency height, electrical heating steam jet refrigerator that noise is low are provided.
Technical solution of the present utility model:
A kind of electrical heating steam jet refrigerator, it is by drum 1, electric heater 2, level pressure device 3, injector 4, condenser 5, expansion gear 6, evaporimeter 7, backflow injector 8 and check valve 9 are formed, wherein the outlet of injector 4 is communicated with condenser 5 imports, the outlet of condenser 5 is communicated with evaporimeter 7 imports by expansion gear 6, the outlet of evaporimeter 7 is communicated with the suction inlet of injector 4, it is characterized in that being equipped with in the drum 1 low pressure fluorine Lyons working medium, and by electric heater 2 heating, the upper port of drum 1 is communicated with the import of injector 4 and the import of backflow injector 8 by level pressure device 3 simultaneously, the outlet of backflow injector 8 is communicated with another upper port of drum 1 by check valve 9, and the suction inlet of backflow injector 8 is communicated with the outlet of condenser 5.
The utility model is a working medium with fluorine Lyons, with the liquid refrigerant in the electric heater indirect drum, produce the power steam of the saturated vapor of certain pressure as injector, spray by nozzle, make by evaporimeter working substance steam taken out and drawn, the cooler condensation is delivered in compression, through the evaporation of expansion gear devaporation device, reaches the purpose of refrigeration.The utility model is simple in structure, and production cost is low, and is reliable, and noise is very little, sprays mixing ratio and ejection efficiency and improves greatly.The utility model unit can be applicable on the window air conditioner, can with the state-of-the-art Refrigeration Technique U.S. that combs mutually, multi-machine parallel connection can be applicable to floor air conditioner and large-scale centralized formula refrigeration machine, and availablely opens, stops part of generating units and regulate load, makes operation more reasonable.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the utility model is set up the low pressure working fluid in an electric heater 2 indirect drums 1, electric heater 2 can adopt the electric furnace heating wire heater, and and external insulation, it promptly can be placed in the drum 1, also can be placed in the outside of drum 1, liquid refrigerant in drum 1 is heated evaporation, when pressure reaches certain value, level pressure device 3 starts, power steam is by injector 4 outlet ejections, make to be taken out and draw from the working substance steam of evaporimeter 7, compression is delivered to condenser 5 and is condensed into liquid state, wherein a part of condensate liquid can adopt expansion valve through expansion gear 6(, also can adopt the expansion tube coupling to constitute) be sent to evaporimeter 7 sweat coolings, another part condensate liquid injector 8 that refluxed is taken out tying-in check valve 9 and is sent back in the drum 1.Because the fluorine Lyons R in the drum 1

21Or R
113Or R
114Or the critical-temperature of some other low-pressure low-temperature cold-producing medium is all higher, their required evaporating pressures under 5-15 ℃ of condition all are far longer than water, so they can reduce widely from the exit velocity of injector 4, can be lower than velocity of sound, thereby reduced noise effectively, their injection mixing ratio has bigger increase simultaneously, can be greater than 1, so ejection efficiency is increased.
Claims (4)
1, a kind of electrical heating steam jet refrigerator, it is by drum 1, electric heater 2, level pressure device 3, injector 4, condenser 5, expansion gear 6, evaporimeter 7, backflow injector 8 and check valve 9 are formed, wherein the outlet of injector 4 is communicated with condenser 5 imports, the outlet of condenser 5 is communicated with evaporimeter 7 imports by expansion gear 6, the outlet of evaporimeter 7 is communicated with the suction inlet of injector 4, it is characterized in that being equipped with in the drum 1 low pressure fluorine Lyons working medium, and by electric heater 2 heating, the upper port of drum 1 is communicated with the import of injector 4 and the import of backflow injector 8 by level pressure device 3 simultaneously, the outlet of backflow injector 8 is communicated with another upper port of drum 1 by check valve 9, and the suction inlet of backflow injector 8 is communicated with the outlet of condenser 5.
