Freezer size is depending on designing storage capacity, and using freezer center as origin, circular ring shape is built by interval of 3m in the direction radius R
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
2 Fans are mounted equidistant in road；When R is 6-9m, the installation of 3 Fans is mounted equidistant in outermost loop tunnel；It is outermost when R is 9-12m
4 Fans are mounted equidistant in side loop tunnel.
Cool house internal fan outlet wind speed, temperature are determined by Refrigerating House Design operating condition.
Cold-storage door is installed on the positive downside of blower, and Ku Men uses light steel thermal insulation material having a size of 3m wide × 2.5m high, library door.
It is 3m with radius so that radius R is the freezer of 6m as an example, a height of 3.5m, wall thickness is the cylindric freezer conduct of 0.2m
Consolidated storage, it is 3m that wall builds width outside, and cylindrical freezer is divided into two relatively by wall by the loop tunnel region of a height of 3.5m
Region；The loop tunnel region of formation is blown into freezer from fan outlet as a flow-guiding structure, cold air, along annular tunnel
Road flowing takes away heat in library, reach next blower return air inlet by heat band outbound outside, from blower after aerial cooler cools down
Air outlet enters freezer, so as to form a process of refrigerastion；The loop tunnel of 3m wide significantly reduces flow field area of section, makes
The kinetic energy of blower is transmitted to farther by cooling air, and by numerical simulation calculation, the loop tunnel of 3m wide can effectively group
Knit air flow method.Freezer is isolated into relatively independent space by wall, can realize cooling, two kinds of freezing in different flow field regions
Working environment realizes the dual-purpose use in a library.In loop tunnel, blower is installed at interval of 20m, distance makes wind between appropriate adjusting blower
Machine is uniformly distributed in cool house internal；The distribution of blower, using freezer center as rotation center, rotation angle is 180 ° of uniformly installations 2
A blower, each assembling is at tunnel center, range bin top 0.2m；Cold-storage door installation site is characterized in that: cold-storage door peace
Loaded below blower, library door center line is generally aligned in the same plane with blower；The library use brick mix structure, and the wall of freezer,
Floor and flat-top all apply certain thickness heat-barrier material, to reduce extraneous incoming heat；In order to reduce the radiation for absorbing the sun
Can, the general painted white of freezer exterior wall surface or light colour.
By carrying out numerical simulation calculation to freezer flow field region, air outlet speed is 2m/s, and leaving air temp is -23
℃.Analog result discovery has no flow dead zone in library, and Flow Field Distribution is uniform.
Such annular tunnel type freezer structure can effectively improve library flow field uniformity, subtract storehouse temperature gradient
Small, preferable to solve in traditional square freezer, fluid temperature (F.T.) is unevenly distributed, haves the defects that flow dead zone, and building structure letter
It is single, freezer fluid flow uniformity, which is improved, for research provides a kind of new thinking.
