When entering the room air of shell and flowing through metallic conduit, heat exchange first is carried out with its internal outdoor air inlet, subsequently into heat exchanger
Sufficient heat exchange is carried out with outdoor air inlet, while heat exchanger is equipped with heat source, heat source enters two strands after opening in the sky of heat exchange
Gas is all preheated, and guarantees that the outdoor cold air introduced reaches suitable temperature；The inside of first, second nozzle of metal tube has
There are thermally conductive hexagonal honeycomb holes, the air flowed through can be preheated rapidly, solves the problems, such as that conventional pipelines pre-heat effect is poor.Heat source
For cylinder type heating film, it is possible to provide uniform, comprehensive heat supply, the end of above-mentioned cylinder type heat source, which is additionally provided with, to be covered in metallic conduit
On nonmetallic heat insulation loop, avoid the thermal energy of heat source from conducting outward along metal tube, be effectively conducted thermal energy to hot-air to be added, drop
The loss of low calorie.
In conclusion above-mentioned preheating structure runs heating mode auxiliary at low ambient temperatures opens new blower, guarantee to introduce
The heat source of indoor fresh air proper temperature, use is unrelated with the heating of air-conditioning system circulation, ensure that the reliable of new fan operation
Property and safety.
