Problems solved by technology

However, due to the installation of a full-heat heat exchanger in this fresh air system, the air resistance increases, resulting in an increase in fan energy consumption.
The total heat exchange efficiency of the total heat heat exchanger is generally about 60%, and the heat exchange efficiency will drop significantly as the use time increases
At the same time, conventional fresh air systems are expensive, which inhibits market promotion

Abstract

The invention discloses a novel building fresh air system. The novel building fresh air system comprises a fresh air inlet, a fresh air draught fan, a fresh air supply port, a lower exhaust port, an exhaust draught fan, an exhaust lower transverse pipe, an exhaust flow dividing pipe, exhaust vertical pipes, an exhaust flow gathering pipe, an exhaust upper outlet, an exhaust upper transverse pipe,a habitable room, a first outer wall and a second outer wall. An exhaust system is arranged in the outer walls and can conduct same-way type balanced exhaust heat exchange, the cooling capability of the indoor exhaust air in summer and heat of the indoor exhaust air in winter can be sufficiently utilized, a total heat exchanger does not need to be installed, and air resistance and draught fan energy consumption are effectively reduced. The structure is simple, maintenance is convenient, the service life is long, the cost and running expense are low, and application and popularization are facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of HVAC, in particular to the technical field of a novel building fresh air system. 【Background technique】 [0002] With the improvement of living standards, people's requirements for indoor air quality are also getting higher and higher. Due to the airtightness of modern buildings is getting better and better, a large number of decoration, the use of various indoor equipment and personnel activities, the indoor air quality has dropped significantly, and the use of air conditioners has exacerbated this phenomenon. Usually in the air-conditioned room, the doors and windows are closed tightly, and the fresh air from the outside cannot enter the room to dilute the indoor pollutant gas. In order to cope with this situation, a building fresh air system has emerged, which introduces outdoor fresh air into the room through the fresh air duct. While introducing outdoor fresh air, it also needs to exhaust almost t...
