Description
Technical field
The utility model relates to a kind of cooling air unit, and especially circulation leaks out the circulation type super low temperature air cooler of ultralow temperature air-out.Belong to technical field of refrigeration equipment.
Background technology
At present, known common cooling air unit adopts phreatic water or single stage compress refrigeration machine to obtain cold wind, and the general low-temperature cold wind temperature that obtains goes for the industrial use of comfortableness purposes or common process requirement more than-10 ℃.But the higher industrial operations of some technological requirements need use more the cold air of low temperature just can finish or reach ideal effect.Moreover general air-cooler adopts straight-line suction wind mode, directly draws surrounding air, also directly enters atmosphere after cold wind uses, and when the cold wind temperature is low (below 0 ℃), evaporimeter frosting is serious, even be equipped with dehumidifier, effect is unsatisfactory.And the straight-line energy consumption is bigger, causes energy waste.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the circulation type super low temperature air cooler that provide a kind of temperature of acquisition lower, evaporimeter is difficult for frosting, energy consumption is low.
The purpose of this utility model is achieved in that a kind of circulation type super low temperature air cooler, it comprises a cover single-stage compression refrigeration system, one cover cascade refrigeration system, air filter, blower fan and air channel, single-stage compression refrigeration system comprises evaporimeter, the cascade refrigeration system comprises evaporimeter, before the evaporimeter of the evaporimeter of described single-stage compression refrigeration system and cascade refrigeration system, after be contained in the air channel, air intake position, described air channel is equipped with air filter, air-out position, air channel is equipped with blower fan, the air-out position in air channel is connected with the cold wind import of corollary equipment, and the air intake position in air channel is connected with the outlet of the tail gas of corollary equipment.Under the effect of blower fan, corollary equipment tail gas enters the air-cooler air channel by air intake position, air channel, the air filter of flowing through, dust-filtering in the tail gas is clean, flow through the again evaporimeter of single-stage compression refrigeration system is drained heat, and temperature is reduced to about-10 ℃, the evaporimeter of the cascade refrigeration system that flows through then, further cooling, temperature is reduced to about-60 ℃, and ultralow temperature cold air is sent into corollary equipment through blower fan and is used for it, the corollary equipment tail gas discharged is sent into air-cooler once more, constitutes circulation.
The utility model circulation type super low temperature air cooler, described single-stage compression refrigeration system comprises refrigeration compressor I, condenser, device for drying and filtering, reservoir, choke valve and evaporimeter, refrigeration compressor I, condenser, device for drying and filtering, reservoir, choke valve and evaporimeter couple together into an airtight closed circuit I with copper pipe successively, charge into cold-producing medium I, constitute a cover single-stage compression refrigeration system; Described cascade refrigeration system comprises refrigeration compressor II, condenser, device for drying and filtering, reservoir, choke valve, evaporative condenser, refrigeration compressor III, oil eliminator, device for drying and filtering, reservoir, choke valve, evaporimeter and expansion vessel, refrigeration compressor II, condenser, device for drying and filtering, reservoir, choke valve couples together into an airtight closed circuit II with copper pipe successively with evaporative condenser, charge into cold-producing medium II, refrigeration compressor III, oil eliminator, evaporative condenser, device for drying and filtering, reservoir, choke valve, evaporimeter also couples together into an airtight closed circuit III with copper pipe successively with expansion vessel, charge into cold-producing medium III, two the whole formation of closed circuit one cover cascade refrigeration systems, evaporative condenser is both as the evaporimeter of closed circuit II, as the condenser of closed circuit III, rely on the evaporation cold of cold-producing medium II to come condensating refrigerant III again.Cold-producing medium III is the super low temperature refrigeration agent, and evaporating temperature is very low, but because its condensation temperature is also low, if employing single-stage compression refrigeration system, condensation at ambient temperature, corresponding condensing pressure is very high, and system does not allow, and high and low pressure has big difference, compression ratio is too big, and the utmost point is unfavorable for compressor operating, is infeasible so the one pole compression refrigerating system is adopted in the agent of class super low temperature refrigeration, must adopt the cascade refrigeration system, rely on the evaporation cold of other cold-producing mediums to reach its condensation.
The utility model circulation type super low temperature air cooler, the evaporimeter of the evaporimeter of described single-stage compression refrigeration system and cascade refrigeration system adopts ribbed pipe type evaporator, good effect of heat exchange, compact conformation.
The utility model circulation type super low temperature air cooler, described air filter are detachable, the convenient cleaning or replacement.
The utility model circulation type super low temperature air cooler, described air channel are detachable, conveniently regularly evaporimeter are cleaned.
The utility model uses two cover refrigeration systems, a cover one pole compression refrigerating system, a cover cascade refrigeration system.By blower fan corollary equipment tail gas is sent in the machine, by air filter, remove airborne dust earlier, form black dirt in order to avoid be infected with on the refrigeration system evaporator fin, influence refrigeration, by unit single-stage compression refrigeration system evaporimeter, temperature is reduced to about-10 ℃ then, again by the cascade refrigeration system evaporator, temperature is reduced to about-60 ℃, ultralow temperature cold air is sent into corollary equipment and is used for it, and the corollary equipment tail gas discharged is sent into air-cooler once more, constitutes circulation.The sealing of whole circulation wind system is also laid heat-insulation layer, there is not outside air to enter in the course of work, except just beginning to have on the evaporator fin in a period of time a little frost layer (portion of water that carries in the circulatory system inner air), remain drying in the quenching system, the serious frosting of evaporator fin can not occur and even stop up the phenomenon of not air-out.Owing to adopt wind circulating system, what air-cooler sucked is corollary equipment tail gas, rather than the external environment air, under the bigger situation of environmental temperature fluctuation, air-cooler all the time can smooth working, and even does not have bigger the fluctuating excessive phenomenon that can't work of loading, and energy consumption is not high yet.
The beneficial effects of the utility model are: leaving air temp is low, reach about-60 ℃, and the evaporimeter frost-free, air-out is smooth and easy, working stability, energy consumption is low.
