Fresh air and returned air proportional control haze removal system and control method thereof

Abstract

The invention discloses a fresh air and returned air proportional control haze removal system. The fresh air and returned air proportional control haze removal system comprises an indoor unit and an outdoor unit; the indoor unit comprises a control device and function modules, the function modules are connected to form an air flue loop, the air flue loop comprises an air returning pipeline, a fresh air pipeline, an air feeding pipeline and an exhaust pipeline, an inlet of the fresh air pipeline is in series connection with a fresh air vale, an inlet of the air returning pipeline is in seriesconnection with an air returning valve, a control device controls the opening degrees of the fresh air valve and the oil returning valve so as to control the fresh air amount and the air returning amount, and controls heat exchange amounts of fresh air and returned air on a full heat exchanger. A control method of the haze removal system is further provided. Through a sensor, the fresh air valve and the air returning valve are controlled so as to control the opening degrees of the fresh air valve and the oil returning valve, the proportion of the fresh air amount and the indoor air returning amount can be accurately controlled, energy brought by the fresh air and energy losses for air purifying are reduced to the minimum, the indoor air purifying efficiency is improved, and comprehensive effective energy-saving treatment of indoor air can be improved.

Description

technical field [0001] The invention belongs to the technical field of air treatment, in particular to a haze removal system for proportional adjustment of fresh air and return air and a control method thereof. Background technique [0002] With the rapid development of my country's social economy, the problem of smog pollution has become more and more serious. Not only the frequency of smog weather is getting higher and higher, but the severity of smog pollution is also increasing. Smog has brought great inconvenience to people's lives, especially damage to people's health. In recent years, the incidence of various respiratory diseases caused by smog is increasing year by year. It is imperative to control smog. The country is improving the relevant system of smog control and adopting various means to control smog. However, the control of smog from the source cannot be completed overnight, and requires a long and arduous process. Since people cannot do without breathing,...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of the single function of the existing haze removal equipment, and solve the problem of energy loss caused by the outdoor fresh air to make the indoor air flow to the outside by controlling the ratio of fresh air and purified return air, so that the indoor air can be fully circulated to ensure indoor air circulation. The cleanliness of the air can improve the indoor air purification efficiency and introduce outdoor fresh air to ensure the freshness of the indoor air.
