Description
Technical Field
The utility model relates to a change white system, concretely relates to steam changes white system.
Background
the defrosting of the current common warehouse internal evaporator adopts more forms of electric defrosting and natural defrosting, and has the characteristics of high speed of electric defrosting, simple construction, convenient control and the like. However, when defrosting the electric defrosting, not only the heat load in the refrigerator is inevitably increased (that is, the cooling capacity of the refrigerator is required to be increased properly), but also the power consumption of the defrosting itself is not small, and the power consumption is not essential for the refrigerated goods. Considering energy conservation and environmental protection, the electrochemical frost energy consumption factor is very prominent in the use process of the refrigeration house.
Disclosure of Invention
To the problem that above-mentioned prior art exists, the utility model provides a steam defrosting system, it is effectual to change the frost, and the defrosting time is short, and is undulant little to the influence of cold storage storehouse temperature.
In order to achieve the above object, the utility model provides a following technical scheme: a hot air defrosting system comprises a condenser, a unit, an air cooler, a high-temperature control system and a low-temperature control system; the high-temperature control system is formed by mutually connecting a front hand valve, a filter, an electromagnetic valve, a high-temperature expansion valve and a rear hand valve in series; the low-temperature control system is formed by mutually connecting a front hand valve, a filter, an electromagnetic valve, a low-temperature expansion valve and a rear hand valve in series; the condenser is connected with the unit, the high-temperature control system and the low-temperature control system are connected between the unit and the air cooler in parallel, the front hand valves of the high-temperature control system and the low-temperature control system are connected with the unit through pipelines respectively, and the rear hand valves of the high-temperature control system and the low-temperature control system are connected with the air cooler through pipelines respectively.
Compared with the prior art, the utility model discloses utilize oil content high temperature high pressure steam to change the frost, steam direct action is on the evaporimeter, and efficiency is greater than the electricity and changes the frost and change the frost naturally far away, and is more energy-conserving than the electrification frost, changes the frost naturally and more saves time.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure: 1. a front hand valve; 2. drying the filter; 3. an electromagnetic valve; 4. an expansion valve; 5. a rear hand valve; 6. evaporator, 7, tee bend, 8, oil content jar, 9, check stop valve, 10, defrosting valve, 11, angle valve, 12, check valve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a technical solution: comprises an evaporator 6, an oil separation tank 8 and a temperature control system; the temperature control system is formed by sequentially connecting a front hand valve 1, a drying filter 2, an electromagnetic valve 3, an expansion valve 4 and a rear hand valve 5 in series, and a one-way valve 12 is also connected in parallel between the front hand valve 1 and the rear hand valve 5; the rear hand valve 5 is connected with one end of an evaporator 6 through a pipeline, and the other end of the evaporator 6 is respectively communicated with an oil separation tank 8 and an air return pipe through a tee joint 7; an angle valve 11, a defrosting valve 10 and a one-way stop valve 9 are sequentially arranged on a pipeline for communicating the evaporator 6 with the oil separating tank 8.
When the aluminum busbar works, the liquid supply is evaporated through the front hand valve 1, the drying filter 2, the electromagnetic valve 3, the expansion valve 4, the rear hand valve 5 and the evaporator 6 to enable the temperature of the cold storage to reach a set value, when the aluminum busbar is frosted to seriously affect the evaporation effect, the electromagnetic valve 3 is closed, the defrosting valve 10 is opened, high-temperature and high-pressure hot gas enters the evaporator 6 through the oil separating tank 8 through the defrosting valve 10, then the evaporator 6 is heated for defrosting through the evaporator 6, and after defrosting is finished, the electromagnetic valve 3 is opened and the defrosting valve 10 is closed; the oil-containing high-temperature and high-pressure hot gas is utilized to defrost, the hot gas directly acts on the evaporator 6, the efficiency is far greater than that of electric defrosting and natural defrosting, and compared with the electric defrosting, the electric defrosting device is more energy-saving, and the natural defrosting time is saved.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
