Description
Technical field
The utility model relates to refrigeration technology field, particularly relates to a kind of closed defrosting air-cooler.
Background technology
Air-cooler is the critical piece of cold storage refrigerating system, is arranged on upper area in freezer, and it is made up of evaporimeter and blower fan, for freezer provides cold.In refrigeration system running, evaporimeter frosting is inevitable phenomenon, and a small amount of frosting can strengthen heat exchange, and a large amount of frosting meetings make heat transfer deterioration, affects the normal work of refrigeration system.So evaporator defrost is absolutely necessary.In freezer, use at present more defrosting mode to have: artificial defrosting, water defrosting, hot gas defrosting and electrical heating defrosting etc.
In hot gas defrosting process, the heat not absorbed by frost layer can be diffused in freezer, according to aerodynamics, first hot gas make upper area in storehouse heat up, and is diffused into gradually lower zone in storehouse, makes storehouse temperature fluctuation larger, upper and lower temperature difference is larger, thereby affects the quality of storage food; These heats not only can not be absorbed by frost layer, increase the defrosting time, also can cause temperature rise larger in the storehouse in, and the cold of this part caloric requirement refrigeration system absorbs, energy consumption increase; In defrost process, manual operation defrosting system, grasps inaccuracy to defrost process, causes defrost to finish to stop in time defrosting system, or defrost does not just complete and stops.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of air-cooler of the fluctuation that can reduce storehouse temperature is provided.
For realizing the technical scheme that the purpose of this utility model adopts be:
A kind of closed defrosting air-cooler, comprise casing and be installed on blower fan and the evaporimeter in casing, position corresponding with described blower fan on described casing is provided with air outlet, position corresponding with described evaporimeter on described casing is provided with air inlet, on described casing, be provided with discharge outlet, air intake control air-valve and air intake control YE are installed on described air inlet, air-out control air-valve and air-out control YE are installed on described air outlet; On described casing outside, box house and evaporimeter, be separately installed with temperature sensor, described casing outside, box house and the temperature sensor on evaporimeter are connected with defrosting controller respectively, and described defrosting controller is connected with described air-out control YE, air intake control YE, blower fan respectively.
On described casing outside, air intake control air-valve and air-out control air-valve, heat-insulation layer is all installed.
Described blower fan is centrifugal blower.
The interface of the interface of described air inlet and described air intake control air-valve closure and described air outlet and described air-out control air-valve closure is separately installed with air-valve encapsulant.
Compared with prior art, the beneficial effects of the utility model are:
1, the air inlet of air-cooler of the present utility model and air outlet place are separately installed with air-valve, close at defrost process stroke valve, can prevent that defrosting heat diffusion from, in storehouse, reducing the fluctuation of storehouse temperature, temperature rise reduces, and is conducive to ensure the Storing quality of stored goods in storehouse.
2, air-cooler of the present utility model utilizes the temperature signal of temperature sensor to judge whether defrosting finishes, thus the start-stop of the refrigeration system of control and defrosting system, and control accuracy is high, has avoided error and the cost of labor of manual control.
3, air-cooler of the present utility model outside is provided with heat-insulation layer, can reduce to greatest extent heat diffusion, and how it is absorbed by frost layer to the greatest extent, thereby defrost time shorten has reduced the energy consumption that defrost needs.
4, air-cooler processing and manufacturing of the present utility model is simple, easy to operate, is easy to install.
