The invention discloses a refrigerating system of three-stage flash-evaporation ejection economizers. The refrigerating system comprises an evaporator, a compressor, a condenser, a first-stage high-pressure flash-evaporation-tank economizer, a first-stage ejector, a second-stage flash-evaporation-tank economizer, a second-stage ejector and a third-stage economizer. The refrigerating system has a simple structure, high practicability and great using value, and is convenient to use; flash refrigerant steam produced by each stage of economizer is ejected and concentrated into a highest-pressure economizer and enters the compressor for compressing, and a liquid refrigerant produced by the economizers is ejected and concentrated into a lowest-pressure economizer and enters the evaporator for secondary evaporation, so that the refrigerating cycle efficiency of the economizers is remarkably increased.
Description
Technical field
The present invention relates to the air-conditioning refrigeration system technical field, specifically is a kind of refrigeration system of three grades of flash distillation injection economizers.
Background technology
Adopting economizer cycle is to improve a kind of effective means of refrigeration system efficient; This technology adopts on the liquid refrigerants pipeline flash tank or heat exchanger economizer is set; The throttling shwoot refrigerant steam of refrigeration system intermediate pressure is directed into the economizer interface of compressor intermediate pressure; Formation can improve refrigerating efficiency near the multi-stage compression kind of refrigeration cycle.In order further to improve economizer efficient, also can adopt multistage economizer, form kind of refrigeration cycle near multi-stage compression.In addition, the condenser of refrigeration system is to the very big pressure differential energy of existence between the evaporimeter, and the direct throttling step-down of choke valve commonly used produces irreversible energy loss, how to recycle this energy and is significant.
Summary of the invention
The technical problem that the present invention will solve provides a kind of refrigeration system of three grades of flash distillation injection economizers, the problem of pressure differential energy loss between condenser and the evaporimeter in the existing refrigeration system of solution.
Technical scheme of the present invention is:
A kind of refrigeration system of three grades of flash distillation injection economizers comprises evaporimeter, compressor, condenser, one-level hp flash drum economizer, one-level injector, two-stage flash jar economizer, secondary injector and three grades of economizers; Described evaporimeter, compressor and condenser are communicated with successively; The high pressure entry of described one-level injector, low tension outlet and air entry are communicated with the liquid outlet of condenser, the import of one-level hp flash drum economizer, the gas outlet of two-stage flash jar economizer respectively; The gas outlet of described one-level hp flash drum economizer is communicated with compressor, and its liquid outlet is communicated with the import of secondary hp flash drum economizer through the secondary injector; The liquid outlet of described two-stage flash jar economizer is communicated with the import of three grades of economizers, and the liquid outlet of described three grades of economizers is communicated with evaporimeter, and its gas outlet is communicated with the import of secondary economizer through the secondary injector.
The liquid outlet of described three grades of economizers is communicated with evaporimeter through evaporator throttle valve; Described three grades of economizers are provided with air inlet, and its air inlet is communicated with evaporimeter through three grades of economizer choke valves.
Described three grades of economizers are selected heat exchange type economizer or flash tank economizer for use.
According to the practical operation requirement, according to the present invention in the syndeton of economizer and injector also can design the refrigeration system of two-stage flash injection economizer or the refrigeration system of multistage flash evaporation injection economizer more accordingly.
The present invention is between condenser and the high pressure economy device, be provided with injector between the economizers at different levels of adjacent pressure; Through the injection throttling and recycle the pressure difference energy of liquid refrigerants between condenser, economizer at different levels and the evaporimeter; The refrigerant steam of the low pressure shwoot that produces in the economizer that pressure is lower is defeated to be delivered in the more higher leveled flash tank economizer of pressure successively; Finally all shwoot refrigerant steam get into compressor intermediate pressure economizer interface together in the high pressure economy device; Form economizer cycle, produce higher kind of refrigeration cycle efficient than traditional economy device.
The present invention is simple in structure, and is easy to use, through the cooperation that is connected of flash vaporization jar economizers at different levels and injector throttlings at different levels; The shwoot refrigerant steam that economizers at different levels are produced focuses in the maximum pressure economizer; Get in the compressor then and compress, the liquid coolant of economizer generation simultaneously focuses in the economizer of minimum pressure, gets into evaporimeter then and evaporates once more; Thereby significantly improved the efficient of economizer kind of refrigeration cycle, had very big practicality and use value.
