Abstract

The invention provides an indoor ventilation system. The indoor ventilation system comprises an air supplement end and an air exhaust end, wherein the air supplement end comprises a first air supplement pipeline, an efficient filter, an air supplement fan, an auxiliary electric heating device, a second air supplement pipeline and an air supplement outlet which are sequentially arranged; the air exhaust end comprises an air exhaust inlet, a first air exhaust pipeline, an air exhaust fan and a second air exhaust pipeline which are sequentially arranged; and the air outlet of the first air supplement pipeline and the air inlet of the second air exhaust pipeline are arranged in parallel. The indoor ventilation system further comprises a heat-pipe heat exchanger, wherein one end of the heat-pipe heat exchanger stretches into the air outlet of the first air supplement pipeline, and the other end of the heat-pipe heat exchanger stretches into the air inlet of the second air exhaust pipeline. Through the indoor ventilation system provided by the invention, the problem of mutual contact between exhausted air and supplemented air existing in a heat recovery manner adopted by a ventilation system in the related technologies is solved, and the mutual contact between the exhausted air and the supplemented air is avoided.

Description

technical field [0001] The invention relates to the field of ventilation, in particular to an indoor ventilation system. Background technique [0002] The ventilation and exhaust equipment of the existing laboratories are fume hoods and exhaust hoods, all of which are targeted point-shaped exhaust facilities, and there is basically no exhaust scheme for the entire room. Moreover, the above-mentioned exhaust equipment is very dependent on the pipes of the overall exhaust system. If the position of the exhaust pipe well and the roof exhaust fan are not pre-designed, the odor cannot be discharged in the laboratory. This causes the problem that different floors and rooms share the same exhaust system, and the gases discharged from different laboratories are mixed in the pipeline, which will pose a safety hazard. The air volume cannot be adjusted, and the air volume and distribution of other laboratories will be affected while the ventilation system of one laboratory is being tr...
