The building of the 2.1.2 articles setting central heating, life area or operating zone ground mean wind speed, are answered in winter room
Meet the following requirements：
First, civil buildings and industrial enterprise's ancillary building, not preferably greater than 0.3m/s；
2nd, the job site of factory, it is unsuitable big when indoor radiating amount is less than 23W/m3 [20kcal/ (m3h)]
In 0.3m/s；
Heating will meet the aspect regulation of the above two in large space.Often depth is very big for large-space clean factory building, 50m~100m
Have, traditional mode uses radiator (radiator) free convection form, and the region very little that can be radiated, builds in large space
It is poor to build interior heating effect.In view of being not take up working space as far as possible, radiator is difficult to arrange in large span room.It is and natural
Heating system based on convection heat transfer causes temperature gradient big, up to 0.5~1.0 DEG C/m, make a large amount of hot-airs gather roof and
Lose, but below 2m personnel operating area air themperature skewness, do not reach heating requirement.Heating system be not merely for
Building, be room air service, and should be people-oriented, in addition to manufacturing technique requirent is met, with personnel comfortably with reducing energy consumption
For main target.
Many heating equipments carry out targetedly technology for technical problem existing for heating in large-space clean factory building at present
Improve, the utility model is exactly to realize a kind of comfortable heating designs in large-space clean factory building special air conditioner equipment
Utility model content
(1) technical problems to be solved
Depth is very big in large-space clean factory building thing, how to realize and is not take up ground space and makes uniformly to make in wide area
Heat；Hot-air rises naturally in large-space clean factory building, cause in space up and down temperature gradient it is big, ground handling area temperature is low, and
Roof temperature is high, and heat energy loss is very big.
(2) technical solution
Air-conditioning products are lifted on roof involved by the utility model, are realized by the heat exchanger in equipment to the fast of air
Speed heating, then using efficient air distributing device by hot-air from top to bottom be evenly distributed to space everywhere, decontamination chamber
Interior bad temperature layer；Recycled again by being installed on the axial flow blower recycling top hot-air inside equipment, greatly save energy consumption.
Axial flow blower is placed in below heat exchanger, this structure compared with put on wind turbine before for, heat exchanger can be made fully to exchange heat, greatly
Width improves heat exchange efficiency, increase heating capacity, and can effectively reduce windage, increase air output and outlet air wind speed, so that air quantity is more
Greatly, air supplying distance is farther.
The gas flow rate and distributing angle of air distributing device are adjustable, can meet without using larger air mass flow
Temperature requirement, realizes calm sense in working region, makes staff's sensible temperature in space, comfortable.
(3) beneficial effect
This structural change can improve heat exchange efficiency, increase heating capacity；Reduce windage, increase air quantity, increase air supplying distance.
Hot-air is from top to bottom evenly distributed to space everywhere by air distributing device using forced convertion mode, and separate unit is set
Standby area coverage is big, effectively solves the problems, such as that depth is very big in pile.
The gas flow rate of air distributing device can carry out the automatic electrodeless adjustment of rotation speed of fan, section according to the change of environment temperature
Save electric energy.
The air-flow distributing angle of air distributing device can be adjusted in real time according to height and control area, meet indoor living area
Domain or the requirement of operating area wind speed.
