Description
Technical field
The refrigeration low-temperature air-cooler system that this utility model a kind of energy stable operation uses, belongs to refrigeration technology field。
Background technology
The many employings of cryogenic refrigerating system are bipolar or Cascade refrigeration cycle, the evaporating temperature of its cold-producing medium is in most cases below-40 DEG C, in this operating mode is run, due to setting separating of oil in refrigeration system, after compressor, in refrigerant vapour, major part lubricating oil is separated, though but use which kind of high-efficiency oil separator, the lubricating oil in cold-producing medium 100% can not be separated, the cold-producing medium of cooling cycle system more or less all contains lubricating oil。
The freezing point of the refrigeration oil used in current refrigeration system is all at about-40 DEG C, in evaporating temperature more than in the system of-40 DEG C, it is less problematic that cold-producing medium contains a small amount of lubricating oil, and refrigeration system is entirely capable of stable operation under the mounting process and strict working specification of specification。
But in evaporating temperature less than in the refrigeration system of-40 DEG C, refrigerant liquid is in expansion valve throttling process, these cold-producing mediums contain a small amount of lubricating oil, owing to evaporating temperature is less than its solidification temperature, in each branch line of the liquid-dividing head after expansion valve, solidification phenomenon pockety will occur, owing to running continuing of time, it may appear that part pipeline blockage phenomenon。The heat exchange area of such air-cooler greatly reduces, and pipeline heat exchange area frosting is uneven, the phenomenon causing cooling slowly or not to lower the temperature, and makes refrigerant system efficiency decline, forms serious energy waste。
Due to developing rapidly of national economy, less than-40 DEG C evaporating temperature equipment application were few in the past, being only limited in testing equipment and use, belong to discrete use more, the lubricating oil defect that oil solidification brings in pipeline is also inconspicuous, with expanding economy, low-temperature cold store, freezer, the use of quick freezing repository gets more and more, this defect just seems in the urgent need to address, and otherwise cryogenic refrigeration will ensure stable operation。
Utility model content
This utility model overcomes the deficiency that prior art exists, for cryogenic refrigerating system air-cooler, disadvantages described above occurs, according to the existing defrost circuit of air-cooler and moving law, defrost circuit increases auxiliary heating tape, makes low temperature cold vaporizer energy stable operation reach the refrigeration low-temperature air-cooler system of purpose of highly effective refrigeration。
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: the refrigeration low-temperature air-cooler system that the stable operation of a kind of energy uses, including liquid storing barrel and vaporizer, pipeline communication is passed through between described liquid storing barrel and vaporizer, pipeline between described liquid storing barrel and vaporizer is provided with expansion valve, the entrance point of described vaporizer connects with liquid storing barrel, the port of export of described vaporizer connects with the entrance point of compressor, the port of export of described compressor connects with liquid storing barrel, described vaporizer is provided with air-cooler, described air-cooler is provided with defroster, pipeline between described vaporizer and expansion valve is provided with auxiliary heating tape, described auxiliary heating tape is spirally wrapped around on pipeline。
Being provided with controller on described defroster, electrically connect between described controller with defroster and auxiliary heating tape, described controller controls defroster and auxiliary heating tape collaborative work。
Described defroster and auxiliary heating tape synchronous working。
This utility model compared with prior art has the beneficial effect that this utility model is for the lubricating oil freezing problem in pipeline existed in cryogenic refrigerating system, according to the existing defrost circuit of air-cooler and moving law, defrost circuit increases auxiliary heating tape, guarantee that lubricating oil will not solidify in pipeline, thus without influence on the normal operation of vaporizer and air-cooler, make low temperature cold vaporizer energy stable operation, reach the purpose of highly effective refrigeration。
