Background technique

With the improvement of people's living standards, the requirements for indoor air quality are also increasing. In particular, some metropolitan cities have relatively serious smog and high PM2.5 levels, causing people to worry about opening windows for ventilation. At the same time, with the increasing energy shortage in our country, energy saving and environmental protection have become popular among the people. Opening windows and ventilation in houses will inevitably bring about energy loss, which is not in line with the concept of energy-saving buildings and low-carbon life. The ability to recover the heat energy in the exhaust air becomes a requirement.

At present, household fresh air fans are single-stage purification, and high-efficiency filters or electronic purifiers are used for air purification. The new fan using electronic purifier, the purification rate of PM2.5 is 80% to 95%, and it is difficult to improve the purification efficiency. The fresh air fan with high-efficiency filter has a purification rate of PM2.5 of 90% to 97%.

The new fan with electronic purifier needs to clean the integrator regularly, twice a year, and the cost of each cleaning is about 100 yuan. The initial investment is about 500-700 yuan more expensive than the initial investment of the new fan unit with electronic purifier. The new fan with high-efficiency filter needs to replace the high-efficiency filter regularly, twice a year, and the cost of replacing the filter is about 400-600 yuan each time.

Therefore, the single-stage purification of the fresh air unit, either the purification efficiency is not high enough, or the later maintenance cost is too high, and the cost performance is not ideal.
