Description
Technical field
The invention belongs to refrigeration/energy technology field, relate to a kind of New-style refrigeration house, particularly relate to gas in a kind of optimization freezer
Flow distribution and energy-saving and cost-reducing freezer structure.
Background technology
Freezer is as a kind of building providing cryopreservation article, in recent years at food, pharmacy, chemical industry, medical field
It is widely used, but the design aspect of this body structure of freezer is not had the biggest breakthrough, conventional its plane of freezer
The most square, owing to without backflow guide frame, causing flow field air current flow uneven in running, exist relatively in making storehouse
Big thermograde, affects the operational effect of freezer.Xie Jing (Xie Jing, three dimensional fluid mechanics prediction blower fan difference arrangement form pair
The impact of freezer air-flow, food industry science and technology, 2011, o. 11th: 349-351) by freezer inner blower arrangement form to storehouse
The impact of flow field carries out Three-dimensional simulation, and result shows: after assembling location improvement, airflow homogeneity in freezer
Improve, but due to the restriction of freezer structure itself, higher in freezer corner fluid temperature (F.T.), flow field uniformity is poor.Thus may be used
Seeing, in raising freezer, airflow homogeneity, minimizing flow dead are the key factors improving freezer performance.At present, freezer structure is all
Being square, in storehouse, goods is put in disorder, has had a strong impact on the uniformity of freezer flow field, not only bad for the fast quickly cooling of goods
But, and make blower fan consume a large amount of electric energy, cause freezer operational efficiency low.Carry by improving the arrangement of freezer inner blower
High freezer airflow homogeneity is conventional method, but the restriction of storehouse shape unavoidably exists flow dead in making storehouse, and then
Cause flow field temperature uneven, increase system energy consumption and space waste.
Summary of the invention
The present invention is directed to the defect of existing freezer structure, propose a kind of New-style refrigeration house structure.
Technical scheme includes designing New-style refrigeration house structure, improving freezer flow field uniformity and reduce equipment energy
The measures such as consumption.Concrete technical scheme is:

Blower fan (7), four fan device (8) first blower fan (5), the second blower fan (6) are installed on same straight line sustained height, blower fan air-out, return
Wind direction is vertical with radius；In same flow field areas, between adjacent blower fan, air outlet direction is arranged as same direction of rotation, and i.e.
One fan outlet is to the second blower fan return air inlet；First blower fan (5), the second blower fan (6) is installed on the first freezer body of wall (1) and the
Center position between two freezer bodies of wall (2), the 3rd blower fan (7), four fan device (8) are installed on distance the second freezer body of wall (2) 1m
Position；Setting height(from bottom) unified by blower fan is that blower fan end face is away from freezer top 0.2m；Cold-storage door installation site is characterised by: cold-storage door is installed
Below blower fan, storehouse door centrage is generally aligned in the same plane with blower fan；Storehouse body uses brick mix structure, and interior wall covers heat insulation material
Material.
Freezer wall main body uses reinforced concrete structure, and adhesive insulating layer inside freezer body of wall, protection against the tide is done in heat-insulation layer both sides
Processing every vapour, civil engineering overcoat is done in inner side, and heat-insulation layer uses thickness to be the polystyrene foam plastics of 0.15m.
Freezer size is depending on design storage capacity, and with freezer center as initial point, radius R direction builds annular with 3m for interval
Body of wall；Depending on assembling number apparent radius R, when R is 3m, two Fans are mounted equidistant；When R is 3-6m, outermost annular tunnel
Road is mounted equidistant 2 Fans；When R is 6-9m, outermost loop tunnel is mounted equidistant 3 Fans and installs；When R is 9-12m, outermost

Cold-storage door is installed on the positive downside of blower fan, and Ku Men a size of 3m width × 2.5m is high, and storehouse door uses light steel insulation material.
As a example by the radius R freezer as 6m, with radius as 3m, a height of 3.5m, wall thickness is the cylindric freezer conduct of 0.2m
Consolidated storage, builds the region, loop tunnel of a width of 3m, a height of 3.5m outside wall, by body of wall, cylinder freezer is divided into two relatively
Region；The region, loop tunnel formed is as a flow-guiding structure, and cold air is blown into freezer from fan outlet, along annular tunnel
Heat in storehouse is taken away in road flowing, arrives next blower fan return air inlet by outside heat band outbound, from blower fan after air cooler is lowered the temperature
Air outlet enters freezer, forms a process of refrigerastion with this；Loop tunnel wide for 3m significantly reduces flow field area of section, makes
The kinetic energy of blower fan is delivered to farther by cooling air, and through numerical simulation calculation, loop tunnel wide for 3m can group effectively
Knit air flow method.Freezer is isolated into relatively independent space by body of wall, can realize cooling, freezing two kinds in different flow field regions
Working environment, it is achieved the dual-purpose use in storehouse.In loop tunnel, installing blower fan at interval of 20m, the suitably spacing of regulation blower fan makes wind
Machine is uniformly distributed in cool house internal；The distribution of blower fan, with freezer center as center of rotation, the anglec of rotation is 180 ° of uniform installations 2
Individual blower fan, each assembling is in center, tunnel, at the 0.2m of range bin top；Cold-storage door installation site is characterised by: cold-storage door is pacified
Being loaded on below blower fan, storehouse door centrage is generally aligned in the same plane with blower fan；Storehouse body uses brick mix structure, and freezer wall,
Floor and flat-top all apply certain thickness heat-barrier material, to reduce extraneous incoming heat；In order to reduce the radiation absorbing the sun
Can, the general painted white of freezer exterior wall surface or light colour.
By freezer flow field region is carried out numerical simulation calculation, air outlet speed is 2m/s, and leaving air temp is-23
℃.Analog result there is no flow dead in finding storehouse, and Flow Field Distribution is uniform.
This kind of annular tunnel type freezer structure can be effectively improved storehouse flow field uniformity, makes storehouse temperature gradient subtract
Little, preferably solve in traditional square freezer, fluid temperature (F.T.) skewness, there is the defect of flow dead, and building structure letter
Single, improve freezer fluid flow uniformity for research and provide a kind of new thinking.
