Abstract
The utility model discloses a Freon calandria type refrigerating and defrosting system of a refrigeration house, which comprises a closed refrigeration circulation loop formed by a compressor, an oil separator, a condenser, a gas-liquid separator, a liquid supplying pipe, a plurality of groups of calandria evaporators and a gas return pipe. The oil separator is connected with a hot Freon defrosting pipe, and the hot Freon defrosting pipe is connected with the calandria evaporators. The Freon calandria type refrigerating and defrosting system of the refrigeration house is reasonable in structural design and good in defrosting effect, avoids reduction of heat exchange efficiency of the outer walls of the calandria evaporators, improves refrigeration effect of the refrigeration house, and reduces power consumption of the refrigeration house.
Description
Technical field
The utility model relates to refrigeration technology field, relates in particular to a kind of freon calandria freezer refrigerating, defrost system.
Background technology
The operation principle of freon freezer is; The cold-producing medium low-pressure steam is a superheated vapor through compressor compresses; Then through condenser condenses to highly pressurised liquid, highly pressurised liquid absorbs the outer heat of comb through getting into the evaporation comb behind the filter, throttle mechanism during the cold-producing medium evaporation; Through the reciprocating operation of above-mentioned flow process, reach the purpose of refrigeration.Since evaporation comb internal and external temperature great disparity, the easy frosting of evaporation comb outer tube wall, the heat exchange efficiency of frost layer influence evaporation comb, and then the freezer refrigerating effect is descended, power consumption increases.Because the frost layer evenly is covered in the comb surface usually, the comparatively trouble that manually defrosts does not have the means that defrost comparatively easily at present as yet.
The utility model content
For overcoming above-mentioned technical problem, the utility model provides freon calandria freezer refrigerating, defrost system a kind of reasonable in design, easy to operate.
For realizing above-mentioned technical purpose; The utility model is to adopt following technical scheme to realize: a kind of freon calandria freezer refrigerating, defrost system; Comprise by compressor, oil eliminator, condenser, storage liquid valve, gas-liquid separator, filter, feed pipe, organize cooling grid, muffler etc. more through the pipeline connection; The airtight refrigeration cycle that constitutes is equipped with feed flow hand valve, magnetic valve, heating power expansion valve between feed pipe and each cooling grid, return-air hand valve is housed between each cooling grid and the muffler; It is characterized in that: oil eliminator is connected with heat in addition through an intake valve and fluoridizes the frost pipe; Heat is fluoridized the frost pipe and is linked to each other with each cooling grid liquid feeding end, and is provided with defrosting hand valve between the two, is provided with the relief pipe that strides across return-air hand valve between cooling grid and the muffler.
The utlity model has following beneficial effect: stop to supply with refrigerant liquid to cooling grid; Treat that its inner refrigerant liquid evaporates the back and fluoridizes the frost pipe to cooling grid the supply system refrigerant vapor through heat; Pressure, temperature in the cooling grid are risen, play the purpose of white melting layer.Its reasonable in design, defrosting effect is good, avoids the heat exchange efficiency of cooling grid outer wall to reduce, and has improved the refrigeration of freezer, has reduced the power consumption of freezer.
Description of drawings
Accompanying drawing is the utility model principle schematic.
Among the figure, 1, compressor, 2, oil eliminator, 3, condenser, 4, gas-liquid separator; 5, filter, 6, intake valve, 7, heating power expansion valve, 8, magnetic valve, 9, defrosting hand valve; 10, feed flow hand valve, 11, relief pipe, 12, return-air hand valve, 13, cooling grid; 14, storage liquid valve, 15, feed pipe, 16, muffler, 17, heat fluoridizes the frost pipe.
The specific embodiment
Shown in accompanying drawing, compressor 1, oil eliminator 2, condenser 3, storage liquid valve 14, gas-liquid separator 4 link to each other successively and constitute closed circuit; The liquid outlet of gas-liquid separator 4 connects filter 5, feed pipe 15 successively, organizes cooling grid 13 more; Be provided with feed flow hand valve 10, magnetic valve 8 between cooling grid 13 and the feed pipe 15; Cooling grid 13 liquid feeding ends are provided with heating power expansion valve 7; The outlet side connects muffler 16 through return-air hand valve 12, and muffler 16 connects gas-liquid separator 4; The cycle refrigeration system of above-mentioned formation freezer, its operation principle and prior art are identical, repeat no more here.
Its defrosting part comprises that a heat that is connected with oil eliminator 3 through intake valve 6 is fluoridized and whitely manages 17; Heat is fluoridized frost pipe 17 and is linked to each other with each cooling grid 13 liquid feeding end; And be provided with defrosting hand valve 9 between the two, be provided with the relief pipe 11 that strides across return-air hand valve 12 between cooling grid 13 and the muffler 16.
Its Defrost method and principle are: stop to treat cooling grid 13 feed flows of defrosting through closing feed flow hand valve 10, and compressor 1 continues operation, the remaining liquid in refrigerating circuit evaporates gradually and is compressed machine 1 and sucks; There is not refrigerant liquid to exist after 5 minutes in the loop; At this moment close return-air hand valve 12, open intake valve 6 and defrosting hand valve 9, refrigerant vapour can get in the cooling grid 13 fast; Cause that comb pressure, temperature rise white melting layer; Because return-air hand valve 12 has cut out; And the liquid of condensation carries out getting into muffler 16 behind the expenditure and pressure in 11 pairs of comb condensers 13 of relief pipe of cross-over connection return-air hand valve 12; The superheated vapor neutralization of returning at this refrigerant liquid that is depressurized and other cooling grids 13; Remaining liquid flows in the gas-liquid separator 4 of taking back thermal cycle, flashes to the machine that is compressed behind the gas 1 and absorbs and continue to recycle; When the most or white layer of the white stratification of comb outer wall is no more than 10mm, close defrost hand valve 9, the cold-producing mediums in the cooling grid 13 are let out through relief pipe 11 and are got back in the compressor 1, and can not cause compressor 1 moisture absorption; Open feed flow hand valve 10 and return-air hand valve 12 at last, recover refrigeration.
