Description
Technical field
The utility model relates to a kind of combined steam ejector refrigeration system, belongs to refrigerating field.
Background technology
Ejector refrigeration system because structure is simple, moving component is few, compact conformation, take up room little, be used widely etc. advantage.
Jet refrigeration circulation system often adopts water, ammonia, HF class, HFC class or HCFC class etc. as refrigeration working medium, compressor and injector combine simply, carry out the low-pressure steam of flash-pot by spout injection at a high speed by the steam after compressor compresses and be compressed into elevated pressures steam, for gaseous working medium at relatively high temperatures condensation create conditions, utilize compressor outlet steam drive injector to carry out circulating and have energy-conservation feature relative to two stage compression refrigeration circulation.
The compression ratio that existing ejector refrigeration technology can provide is lower, has been difficult to the demand of higher compression ratios, though and two stages of compression formula refrigeration solves the problem of compression ratio, it use two compressors, cause electric energy too much to consume.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of combined steam ejector refrigeration system, utilizes the working substance steam produced in intercooler to drive injection afterwards through compressor, economize energy.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of combined steam ejector refrigeration system, comprise compressor, condenser, evaporimeter, injector, intercooler, heat exchange coil, first heating power expansion valve and the second heating power expansion valve, the working substance steam outlet of described injector is connected with the working medium entrance of described condenser, the sender property outlet of described condenser divides two branch roads, described first heating power expansion valve of leading up to is connected with the working medium entrance of described intercooler, the working substance steam outlet of described intercooler is connected with the working medium entrance of described compressor, the sender property outlet of described compressor is connected with the working medium entrance of described injector, another road is connected with the entrance of described heat exchange coil, the outlet of described heat exchange coil is connected with the working medium entrance of described evaporimeter by described second heating power expansion valve, the sender property outlet of described evaporimeter is taken over the injection of described injector and is connected, described heat exchange coil is installed in intercooler.
Compared with prior art, the beneficial effects of the utility model are:
1, after refrigeration system of the present utility model utilizes compressor and injector combination can make full use of compression, high steam orders about injector work, can also improve pressure ratio.Utilize the working substance steam produced in intercooler to drive injection afterwards through compressor simultaneously, do not need other high temperature heat sources, energy-conservation object can be reached.
2, the utility model utilizes compressor to connect with injector and can provide the demand of more high compression ratio.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of the utility model combined steam ejector refrigeration system;
Fig. 2 is the interface diagram of injector.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of combined steam ejector refrigeration system of the present utility model as Figure 1-Figure 2, comprise compressor 8, condenser 2, evaporimeter 6, injector 1, intercooler 7, heat exchange coil 4, first heating power expansion valve 3 and the second heating power expansion valve 5, the working substance steam outlet 13 of described injector 1 is connected with the working medium entrance of described condenser 2, the sender property outlet of described condenser 2 divides two branch roads, described first heating power expansion valve 3 of leading up to is connected with the working medium entrance of described intercooler 7, the working substance steam outlet of described intercooler 7 is connected with the working medium entrance of described compressor 8, the sender property outlet of described compressor 8 is connected with the working medium entrance 14 of described injector 1, another road is connected with the entrance of described heat exchange coil 4, the outlet of described heat exchange coil 4 is connected with the working medium entrance of described evaporimeter 6 by described second heating power expansion valve 5, the sender property outlet of described evaporimeter 6 is connected with the injection adapter 9 of described injector 1, described heat exchange coil 4 is installed in intercooler 7.
Be divided into two parts through the condensed worker quality liquid of condenser 2, a part flows into intercooler 7 after the first heating power expansion valve 3, and a part of working medium enters heat exchange coil 4.Enter the working medium in described intercooler 7 and the working medium generation heat exchange in heat exchange coil 4, produce working substance steam.Working medium after heat exchange coil 4 enters evaporimeter 6 after the second heating power expansion valve 5.The steam produced in intercooler 7 enters the working medium entrance 14 of injector 1 after compressor 8 compresses, by the nozzle 10 of injector 1, to expand and after carrying out flow at high speed, very low pressure is caused in nozzle 10 exit of injector 1, and attract the low pressure working fluid steam in evaporimeter 6, enter the mixing chamber 11 of injector 1, and enter diffuser 12 together with after steam wherein, flow velocity reduction in diffuser 12, pressure enter condenser 2 after raising and condensation occur.The circulation that so goes round and begins again completes process of refrigerastion.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
