Description
Technical field
The utility model relates to a kind of freezer duct type supply air systems.
Background technique
Freezer be food production, processing, distributors important equipment, different classes of food storage environment temperature is not
Together, such as fruit and vegetable needs to store in the environment of 0-15 DEG C, and meat then needs to store up in the environment of -18 DEG C to -30 DEG C
It deposits, and the heat preservation method of the freezer of different temperatures differs greatly, therefore general low temperature and High Temperature Refrigeratory are that independent establish uses.
But the cold air of freezer is directly blown on food from air conditioner in the prior art, leads to the food being directly blown to
Moisture it is readily volatilized, and cold air can not uniformly be spread in freezer, and the temperature at each position is different, influence fresh-keeping quality.
Utility model content
The utility model for the technical problems in the prior art, provides a kind of freezer duct type supply air system, adopts
With distributed air supply duct, air supply duct is arranged in above passageway, avoids blow-through fruits and vegetables, reasonable distribution air output everywhere,
Make the Temperature Distribution of freezer more evenly.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of freezer duct type supply air system, including
Distributed air supply duct and refrigeration system；The refrigeration system includes the first air-cooler to form the first refrigerant circuit, the first system
Cold compressor, combined condenser, fluid reservoir, filter and expansion valve, the refrigeration system further include the second air-cooler, second
Refrigeration compressor, second air-cooler, the second refrigeration compressor and the combined condenser, fluid reservoir, filter and swollen
Swollen valve passes sequentially through pipeline connection, forms the second refrigerant circuit；The combined condenser is also connected with water cooling system；It is described
What distributed air supply duct was connected with the air outlet of first air-cooler and the second air-cooler respectively.
First air-cooler, the first refrigeration compressor are set in Cold storage in the refrigerator room, second air-cooler, the second system
Cold compressor is set in freezer freezing chamber.
The distribution air supply duct includes refrigerating chamber air supply duct and freezing chamber air supply duct.
The distribution air supply duct is arranged above freezer passageway.
The refrigerating chamber air supply duct and freezing chamber air supply duct are respectively provided with multiple air ports being spaced apart.
The blinds wind deflector for adjusting air-out wind direction can be rotated by being equipped at multiple tuyere positions.
The volume damper that can adjust air-out volume is equipped at multiple tuyere positions.
The utility model has the beneficial effects that：
1) air supply duct is arranged in above passageway, avoids blow-through fruits and vegetables；
2) compared with consentrated air supply formula, reasonable distribution air output everywhere makes the Temperature Distribution of freezer more evenly；
3) the two set air-coolers and refrigeration compressor in parallel by setting, and shared combined condenser, water are cooling
System, fluid reservoir, filter and expansion valve reduce whole on the basis of meeting the temperature and moisture control demand of refrigeration and freezing respectively
A system bulk reduces equipment cost.
Detailed description of the invention
Fig. 1 is a kind of freezer duct type supply air system refrigeration system schematic diagram of the utility model；
Fig. 2 is a kind of freezer duct type supply air system distribution air supply duct schematic diagram of the utility model.
In attached drawing, parts list represented by the reference numerals are as follows：
1, distributed air supply duct, 11, refrigerating chamber air supply duct, 12, freezing chamber air supply duct, 111, blinds wind deflector,
2, the first air-cooler, the 3, first refrigeration compressor, the 4, second air-cooler, the 5, second refrigeration compressor, 6, combined condenser, 7,

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figs. 1-2, a kind of freezer duct type supply air system, including distributed air supply duct 1 and refrigeration system；It is described
Refrigeration system includes the first air-cooler 2 to form the first refrigerant circuit, the first refrigeration compressor 3, combined condenser 6, liquid storage
Tank 8, filter 9 and expansion valve 10, the refrigeration system further include the second air-cooler 4, the second refrigeration compressor 5, and described second
Air-cooler 4, the second refrigeration compressor 5 and the combined condenser 6, fluid reservoir 8, filter 9 and expansion valve 10 pass sequentially through
Pipeline connection, forms the second refrigerant circuit；The combined condenser 6 is also connected with water cooling system 7；The distributed air-supply
What pipeline 1 was connected with the air outlet of first air-cooler 2 and the second air-cooler 4 respectively.
Refrigerant becomes the gaseous state freon of low-temp low-pressure after air-cooler evaporating pan in-tube evaporation, passes through return line quilt
Respective compressor sucking, becomes the gas of high temperature and pressure, it is laggard to isolate lubricating oil therein through fluorocarbon oil separator after compression
Enter combined condenser 6, is cooled by water in combined condenser 6 as highly pressurised liquid, the freon liquid of high pressure is in pressure
Effect flows down through filter 9, expansion valve 10, liquid freon reducing pressure by regulating flow, into air-cooler evaporation coil in after gasification absorb
Heat reduces air themperature in library, and the liquid freon of high temperature and pressure becomes the gaseous state freon of low-temp low-pressure again at this time, completes
