Description
Technical field
This utility model belongs to freezer technical field, is specifically related to a kind of freezer compound ventilation air-changing device with refrigerating function.
Background technology
Freezer is mainly used as storage air-cooling system such as the constant temperature to food, milk product, meat, Aquatic product etc., freezer is actually a kind of low-temperature cold store (freezer) and falls within the one of refrigeration plant compared with refrigerator, its refrigeration area is much bigger, but they have the refrigeration principle communicated; For large-scale fresh-keeping ice house, the mainly vegetalitas goods such as fruit, vegetable deposited. In order to keep the fresh state of storage fruit and vegerable, generally all preserving under the state of cooling, they remain a vital organism in storage. These live bodies, when oxygen supply abundance, are by aerobic respiration. As oxygen supply is not enough, fruit and vegerable just carry out anaerobic respiration and generate the product such as ethanol, acetaldehyde, cause physiological disease, and therefore timely ventilation between chilled storage introduces fresh air, and the cold preservation to fruit and vegerable is particularly important; During freezer ventilation, in storehouse, Cryogenic air is discharged outside storehouse, and outside storehouse, the new wind of high temperature is sent in storehouse, adds the cooling load of storehouse gentleness air-cooler.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of freezer compound ventilation air-changing device with refrigerating function.
This utility model is achieved through the following technical solutions:
A kind of freezer compound ventilation air-changing device with refrigerating function, including a casing, the inner horizontal of casing arranges the dividing plate of an insulation material, and casing is divided into upper outlet passageway and lower inlet channel by dividing plate;
Upper outlet passageway is provided with exhaust blower, and the gas outlet of exhaust blower is to outdoor; Lower inlet channel is provided with air inlet fan, and the gas outlet of air inlet fan is in cold storage chamber; The bottom surface of lower inlet channel is provided with kind of refrigeration cycle entrance and kind of refrigeration cycle outlet, kind of refrigeration cycle entrance is connected by the snakelike refrigeration copper tube being arranged within lower inlet channel with kind of refrigeration cycle outlet, kind of refrigeration cycle entrance and kind of refrigeration cycle export by the external refrigerating plant of pipeline, and arrange electrically-controlled valve on pipeline; At the electric heating sheets that is internally provided with of casing, electric heating sheets is attached on snakelike refrigeration copper tube, and the bottom surface of casing is provided with discharge outlet; The side of casing is provided with the door of the insulation material for closing upper outlet passageway and lower inlet channel.
In technique scheme, described refrigeration copper tube vertically bends setting.
In technique scheme, door is hinged by hinge and casing.
In technique scheme, the bottom surface of casing is the ramp structure tilted to discharge outlet.
Advantage of the present utility model and having the beneficial effect that
When freezer is taken a breath by needs, open door, and open exhaust blower and air inlet fan, open electrically-controlled valve simultaneously and make the refrigerating fluid of refrigerating plant cycle through kind of refrigeration cycle entrance and kind of refrigeration cycle outlet; Exhaust blower drives air in freezer through upper outlet passageway to outdoor discharge, simultaneously air inlet fan drives outdoor fresh air by lower inlet channel to oxygen supply in freezer, owing to being provided with snakelike refrigeration copper tube in lower inlet channel, cooling effect through snakelike refrigeration copper tube can ensure that air low temperature enters freezer, thus reducing the impact that freezer is caused temperature to raise by external air.
When freezer is taken a breath, the snakelike refrigeration copper tube in lower inlet channel is low due to temperature, can be attached to its surface and form frost layer when the steam in external air is by snakelike refrigeration copper tube, and frost layer can have a strong impact on refrigerating efficiency, it is therefore desirable to it is defrosted; When carrying out defrosting, electric heating sheets and power on, refrigeration copper tube is heated defrosting, the white water after thawing is discharged from discharge outlet, thus realizing the defrosting to snakelike refrigeration copper tube, it is ensured that it normally freezes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is upper outlet passageway, and 1-1 is exhaust blower, 2 is lower inlet channel, and 2-1 is air inlet fan, and 2-2 is kind of refrigeration cycle entrance, and 2-3 is kind of refrigeration cycle outlet, and 2-4 is electric heating sheets, and 2-5 is discharge outlet, and 3 is dividing plate, and 4 is door, and 4-1 is hinge.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with specific embodiment.
Referring to accompanying drawing 1, a kind of freezer compound ventilation air-changing device with refrigerating function involved by this utility model, including a casing, the inner horizontal of casing arranges the dividing plate 3 of an insulation material, and casing is divided into upper outlet passageway 1 and lower inlet channel 2 by dividing plate,
The right side of upper outlet passageway 1 is provided with exhaust blower 1-1, and exhaust blower drives air in freezer to outdoor row; The right side of lower inlet channel 2 is provided with air inlet fan 2-1, and air inlet fan drives outdoor fresh air to oxygen supply in freezer; The bottom surface (i.e. the bottom surface of casing) of lower inlet channel 2 is provided with kind of refrigeration cycle entrance 2-2 and kind of refrigeration cycle outlet 2-3, kind of refrigeration cycle entrance is connected by the snakelike refrigeration copper tube being arranged within lower inlet channel with kind of refrigeration cycle outlet, described refrigeration copper tube vertically bends setting, kind of refrigeration cycle entrance 2-2 and kind of refrigeration cycle outlet 2-3 is by the external refrigerating plant of pipeline, and arranges electrically-controlled valve on pipeline; It is internally provided with electric heating sheets 2-4 at casing, electric heating sheets 2-4 is attached on snakelike refrigeration copper tube, and the bottom surface of casing is provided with discharge outlet 2-5, and the bottom surface of casing is the ramp structure tilted to discharge outlet, so that the white water through electric heating sheets thawing can rapidly flow toward discharge outlet, it is to avoid hydrops;
