Description
Technical field
The utility model relates to a kind of integral type heat and fluoridizes white air-cooler, relates in particular to a kind of integral type heat and fluoridizes white air-cooler.
Background technology
At present, more than 80% evaporimeter of miniature cold storage is air-cooler, using the main cause of air-cooler is that electrochemical frost need not be artificial, and existing very large problem, electrochemical frost perplexing installation business and user, be the setting at defrost time and defrost interval, set short, the defrost of defrost time not thoroughly, air-cooler will be blocked by ice after defrost several times.Setting defrost overlong time can cause: 1, defrost power consumption significantly increases, and 2, the power consumption of storehouse temperature rise refrigeration increases, 3, electrothermal tube and evaporimeter life-span reduce even and damage then and there, 4, insulation material melts and reduce even breaking out of fire of heat insulating coefficient.
Suitable defrost time is set and is difficult to grasp, and the factor that consider is quite complicated: 1, the setting at defrost interval, 2, the height of environment temperature, 3, enter the height of storehouse cargo temperature, 4, enter the height of storehouse goods humidity etc.
Summary of the invention
The purpose of this utility model is to provide thorough, safe, the energy-conservation integral type heat of a kind of defrost and fluoridizes white air-cooler.
The purpose of this utility model is achieved through the following technical solutions:
Integral type heat of the present utility model is fluoridized white air-cooler, comprise at least 3 component evaporimeters, every component evaporimeter is respectively equipped with feed pipe and return tube, the feed pipe of every component evaporimeter is connected with the knockout of main feed pipe by capillary respectively, the return tube of every group of evaporimeter is connected with respectively reversal valve, and described reversal valve is connected with main return tube for pipe with hot fluorine.
The technical scheme being provided by above-mentioned the utility model can be found out, the integral type heat that the utility model embodiment provides is fluoridized white air-cooler, comprise at least 3 component evaporimeters, every component evaporimeter is respectively equipped with feed pipe and return tube, the feed pipe of every component evaporimeter is connected with the knockout of main feed pipe by capillary respectively, the return tube of every group of evaporimeter is connected with respectively reversal valve, described reversal valve is connected with main return tube for pipe with hot fluorine, can 1 group of evaporator fan stall defrost, other group evaporimeter refrigeration provides defrost heat, in defrost, continue refrigeration cool-down, utilize not electricity consumption of condensation waste heat defrost, do not affect storehouse temperature, defrost is thorough, safety, energy-conservation.
Accompanying drawing explanation
The integral type heat that Fig. 1 provides for the utility model embodiment is fluoridized the structural representation of white air-cooler.
In figure:
1, main feed pipe, 2, feed pipe, 3, evaporimeter, 4, drip tray, 5, return tube, 6, reversal valve, 7, hot fluorine is for pipe, 8, main return tube, 9, check valve, 10, magnetic valve, 11, expansion valve, 12, capillary.
The specific embodiment
To be described in further detail the utility model embodiment below.
Integral type heat of the present utility model is fluoridized white air-cooler, its preferably the specific embodiment be:
Comprise at least 3 component evaporimeters, every component evaporimeter is respectively equipped with feed pipe and return tube, the feed pipe of every component evaporimeter is connected with the knockout of main feed pipe by capillary respectively, the return tube of every group of evaporimeter is connected with respectively reversal valve, and described reversal valve is connected with main return tube for pipe with hot fluorine.
Every component evaporimeter is respectively equipped with drip tray, and the return tube of every group of evaporimeter coils respectively in drip tray separately.
Described main return tube is connected with outlet with the import of compressor respectively for pipe with hot fluorine.
Described main feed pipe is provided with check valve, magnetic valve and expansion valve.
The operation principle of specific embodiment:
As shown in Figure 1, cooling condition is identical with common air-cooler.No. 1 reversal valve commutation during defrost; close that return gas channel is opened hot fluorine passage, hot fluorine enters No. 1 minute evaporimeter by No. 1 muffler is rapidly heated an evaporimeter; frost in an evaporimeter is melted and is dropped onto in drip tray fast; in drip tray, there is return-air coil pipe (being now hot fluorine pipe) heating chassis; make the defrosting water heating in chassis and dish; in the low temperature of the chassis of heating in freezer, can not freeze; it is stifled that the defrosting water of heating can not freeze ice in drainpipe, guarantees that defrosting water flows out freezer smoothly.The heat release in evaporimeter of hot fluorine is condensed into highly pressurised liquid and enters knockout after by a throttling of knockout capillary, middle press liquid in knockout, be averagely allocated to enter No. 2 after other two capillary second throttles and No. 3 minutes evaporimeters in absorption refrigeration, by compressor, sucked back and be compressed into hot fluorine and send evaporimeter defrost in No. 1 minute to again, successively circulation until defrost complete.During No. 2 evaporimeter defrosts, condensed fluid is averagely allocated to No. 1 and No. 3 evaporimeter absorption refrigerations.During No. 3 evaporimeter defrosts, condensed fluid is averagely allocated to No. 1 and No. 2 evaporimeter absorption refrigerations.The defrost that circulates successively in setting-up time can guarantee that air-cooler moves under best operating mode.Not necessarily 3 groups of the quantity of minute evaporimeter, group number can be determined as required, but minimumly can not be less than 3 groups.
Integral type heat of the present utility model is fluoridized the advantage of white air-cooler:
1,2 to 1 mode of operations, i.e. 1 group of evaporator fan stall defrost, 2 groups of evaporimeter refrigeration provide defrost heat, continue refrigeration cool-down in defrost.
2, utilize not electricity consumption of condensation waste heat defrost, do not affect storehouse temperature, the defrost time can suitably lengthen, thoroughly defrost clean till.
3, defrost speed is fast, and local defrost is suitable time of 1/4th of electrification frost only
4, heat is fluoridized frost for interior thermalization frost, hot fluorine maximum temperature are no more than 90 ℃, can melt insulation material, more can not cause fire.
5, there is not expense in not electricity consumption, cost free operation.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
