Upper-supply and upper-return type air purification system

Abstract

The invention relates to an upper-supply and upper-return type air purification system which comprises a gym air exhaust and ventilation integrated cabinet, an air supply ceiling and an exhaust port, wherein the gym air exhaust and ventilation integrated cabinet is used for inputting fresh air and air to be exhausted, treating the fresh air and the air to be exhausted and outputting the fresh air and the air to be exhausted; the air supply ceiling is used for evenly mixing the induced fresh air and returned air, filtering the induced fresh air and the returned air and outputting the induced fresh air and the returned air into a room; and the exhaust port is used for outputting the air to be exhausted in the room to the outside through the gym air exhaust and ventilation integrated cabinet. Through the air purification system, a plurality of treatment functions including ventilation, exhaust, dehumidification, temperature adjustment, purification and the like are achieved at a time, and waste heat/waste cold is utilized so that energy saving can be achieved, the fresh air treatment function and the returned air treatment function are completely separated, and energy saving is achieved; through a fan filter unit (FFU) installed in the position of the air supply ceiling, fresh air is input into the room (upper supply), returned air is sucked through an air return port in the position of the air supply ceiling (upper return), and an independently arranged air return treatment device, an air return pipeline and a passageway are completely omitted; and the returned air and the fresh air can be evenly mixed, and the outlet air quality is improved.

Description

technical field [0001] The present invention generally relates to the field of ventilation facilities, and in particular relates to an upper-supply and upper-return air purification system. Background technique [0002] With the improvement of living standards, people pay more and more attention to their own health. One way to stay healthy is to keep exercising. As an ideal place for fitness and exercise, gymnasiums are increasingly favored by people because of their well-equipped equipment and professional coaches. However, how to keep the air in the gym clean, which attracts the majority of consumers in the poor outdoor air, due to the severe pollution in the city, especially chemical pollution such as nitrogen oxides and sulfides, and particulate matter pollution such as PM2. It has become an important issue of common concern for gym operators and consumers to still insist on exercising in the gym. In addition, the gym is crowded with people, sweats a lot, and the numb...

Problems solved by technology

If the mixing is uneven, it will directly affect the air quality of the output wind, for example, the oxygen content of the local output wind is low or the temperature is high

However, due to the treatment of dehumidification, temperature adjustment, humidification and purification, the fresh air often has a significantly higher pressure head (or wind pressure) and a correspondingly higher wind speed than the return air. When wind mixing, it is difficult to achieve uniform mixing

However, if the two are mixed in advance in the front pipeline, firstly, a longer mixing pipeline is required, and secondly, the high-pressure head fresh air is likely to hinder the forward flow of the low-pressure head circulation air, and even cause the low-pressure head circulation air to flow backward, that is, the so-called "Air blockage" phenomenon

Therefore, in the prior art, it is generally avoided to directly combine the conveying pipelines of fresh air and circulating air with large difference in transmission pressure head, but first adjust their pressure heads and then merge the two transmission pipelines, which also leads to significant increased cost
