Fresh air ventilator with dust removal and intelligent humidity control functions

Abstract

The invention relates to a fresh air ventilator with dust removal and intelligent humidity control functions. The dust containing fresh air enters a fresh air passage from a fresh air inlet, is filtered, humidified or dehumidified by a wet type filter section and is subjected to energy recovering by a cross-flow type fresh exhaust air heat exchanger and indoor exhaust air, and the clean air meeting the humidity requirement is sent into a room by a blower. An automatic rotary high-pressure spray head of the wet type filter section continuously sprays and filters dust in the fresh air. An indoorrelative humidity sensor measures the relative humidity of the indoor air, transmits the data to a control module, and then the heating quantity of a pipeline type electric heater is adjusted and controlled to adjust the water feeding temperature of the wet type filter section to realize the humidification or dehumidification of the fresh air. According to the fresh air ventilator with the dust removal and intelligent humidity control functions, the humidity of the fresh air can be intelligently controlled while the wet type high-efficiency filtering of the fresh air dust is realized, and a filter element is not changed in the whole process during operation.

Description

technical field [0001] The invention relates to HVAC equipment, in particular to a fresh air ventilator with functions of dust removal and intelligent humidity control. The present invention can also perform humidification or dehumidification treatment on fresh air while performing water-spraying wet dust removal treatment on fresh air, so as to realize intelligent control of indoor relative humidity. Background technique [0002] In recent years, people have paid more and more attention to air pollution, especially indoor air quality. While the public's demand for fresh air ventilators continues to rise, it also puts forward higher requirements for the versatility of fresh air ventilators. [0003] Most of the fresh air ventilators on the market now use filter element filter materials to filter the outdoor fresh air to varying degrees to achieve the purpose of purifying the air. This kind of filter element material will be blocked in a short period of time when the outdoo...

AI Technical Summary

Problems solved by technology

This kind of filter element material will be blocked in a short period of time when the outdoor foggy weather is frequent, and the filter element needs to be replaced frequently to ensure the normal operation of the fresh air ventilator

Although some fresh air ventilators are designed with a bypass channel after the filter is blocked to maintain a continuous supply of fresh air, frequent replacement of filter elements is still inevitable

Due to the relatively high frequency of filter element replacement, the continuous purchase of new filter elements requires a lot of money

And in the process of replacing the filter element, it not only consumes considerable manpower and material resources, but also requires the fresh air ventilator to be shut down to operate, which brings great inconvenience to the use of the fresh air ventilator

[0004] In addition, the environmental and climatic conditions in most areas of our country have high humidity in summer and low humidity in winter. Excessively high or low indoor humidity will reduce the comfort of the occupants.

At present, there are not many intelligent fresh air ventilators that can humidify and dehumidify fresh air ventilators.
