Description
Technical field
The present invention relates to refrigeration technology field, especially a kind of compression secondary injection refrigeration system.
Background technology
Along with improving constantly of human living standard, the consumption of the energy is also constantly increased, and bring a series of problem thus, as power consumption, global warming, environmental pollution etc.Under the shrouding of the shade of these problems, the technology that the eager Seeking Development Through of people is energy-conservation.And Refrigeration Technique consumes a large amount of electric energy every year, be the key areas with energy, therefore developing energy-conservation Refrigeration Technique is a current study hotspot.
The low-grade heats such as ejector refrigeration system can utilize industrial exhaust heat, used heat, solar heat, underground heat drive generation refrigerating capacity and reduce the consumption of the electric energy to preciousness.The energy-saving effect of spraying system is obvious to all, and spraying system parts are simple, and operation maintenance is convenient, and small investment, has good development prospect.But injection refrigerating system also has some weakness, and such as system effectiveness is not high, affects larger etc. by heat source temperature.Therefore, there is people's proposition compressor to assist the pressure of inspiration(Pi) improving injector, improving its operating condition, improving the efficiency of spraying cycle by sacrificing a small amount of electric energy.This kind of system has good application potential, but its flow process also needs perfect further, and efficiency can improve further.
Summary of the invention
In order to overcome the deficiency that efficiency is lower, energy consumption is larger of existing compression secondary injection refrigeration system, the invention provides the new type of compression secondary injection refrigeration system with gas-liquid separator that a kind of efficiency is higher, energy consumption is less.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of new type of compression secondary injection refrigeration system with gas-liquid separator, comprise compressor, condenser, evaporimeter, generator and injector, the outlet of described evaporimeter is connected with the import of described compressor, the outlet of described compressor is connected with the driving fluid import of described injector, the outlet of described injector is connected with the import of condenser, the outlet of described condenser is divided into two tunnels, first via outlet is connected with the import of generator through pump, the working fluid import of the described outlet and described injector of stating generator is connected, described compression secondary injection refrigeration system also comprises first throttle device, second throttling arrangement and gas-liquid separator, second way outlet of described condenser is connected through the import of first throttle device with described gas-liquid separator, the gaseous phase outlet of described gas-liquid separator is connected with the driving fluid import of described injector, the liquid-phase outlet of described gas-liquid separator is connected with the import of evaporimeter by the second throttling arrangement.
Further, described first throttle device and the second throttling arrangement are choke valve, expansion valve or capillary; The working medium adopted can be halogenated hydrocarbons, alkane, carbon dioxide, ammonia etc.; To the low-grade heat source of generator heating, can be waste heat, used heat, solar heat, underground heat etc.
Technical conceive of the present invention is: adopt two-stage throttling, and after one-level throttling, have a gas-liquid separator.Saturated gas and saturated liquid are separated by gas-liquid separator, saturated liquid is made to have more specific refrigerating effect after by further throttling, final refrigerating capacity is not reduced, saturated gas is then without the need to being sucked with regard to injected device by further throttling, not only reduce restriction loss, more be the reduction of the flow that compressor sucks working medium, directly reduce the power consumption of compressor.This system effectively can also reduce temperature when injector driving fluid is inhaled into, and improves the efficiency of injector.Advantage of the present invention can be summarized as: when the present invention strengthens the refrigerating capacity of injection refrigerating system output as much with routine, only need consume less electric energy.。And owing to decreasing the flow of the refrigerating capacity flowing through compressor, less compressor can be used, reduce initial outlay.Also can reduce injector injector fluid temperature (F.T.) in addition and improve its efficiency.
Beneficial effect of the present invention is mainly manifested in: have higher efficiency than existing compression secondary injection refrigeration system, significantly reduce energy ezpenditure.
