Heat exchange fresh air purifier

Abstract

The invention provides a heat exchange fresh air purifier. The heat exchange fresh air purifier comprises a purifier body, a bidirectional heat exchange mechanism and a purification mechanism; the bidirectional heat exchange mechanism and the purification mechanism are arranged on the purifier body; a bidirectional air pipe (1) is arranged on the purifier body; the bidirectional heat exchange mechanism comprises a bidirectional air pipe inlet end (15) and a bidirectional air pipe outlet end (16); and the bidirectional air pipe inlet end (15) and the bidirectional air pipe outlet end (16) are arranged in the bidirectional air pipe (1). According to the heat exchange fresh air purifier, pollutants indoors is purified, meanwhile, outdoor air entering the room and indoor air discharged from the room are subjected to full heat exchange, so that heat is recovered, the situation that the cold air in winter and the hot air in summer are prevented from entering the room is avoided, by introducing the fresh air, the freshness of the indoor air is improved, and the content of indoor CO2 is reduced.

Description

technical field [0001] The invention relates to a purifier, in particular to a heat exchange fresh air purifier. Background technique [0002] Current air purifiers mainly use activated carbon adsorption technology, ozone purification technology, negative ion dust removal technology and high-voltage electrostatic technology. However, these air purifiers can only remove harmful substances in indoor air through indoor closed circulation, but cannot introduce fresh air. Air. After searching the existing technical documents, it is found that the patent document, the publication number is CN103884061A, and the application number is 201410128366.7 discloses a total heat exchange central air environment purification device. The purpose of purifying indoor air is achieved by exchanging indoor and outdoor air, but the process is complex and requires a large amount of fresh air, so it is necessary to install air inlet ducts and air outlet ducts separately.

Problems solved by technology

[0002] Current air purifiers mainly use activated carbon adsorption technology, ozone purification technology, negative ion dust removal technology and high-voltage electrostatic technology. However, these air purifiers can only remove harmful substances in indoor air through indoor closed circulation, but cannot introduce fresh air. Air

After searching the existing technical documents, it is found that the patent document, the publication number is CN103884061A, and the application number is 201410128366.7 discloses a total heat exchange central air environment purification device. To exchange indoor and outdoor air to achieve the purpose of purifying indoor air, but the process is complex and requires a large amount of fresh air, so it is necessary to install air inlet pipes and air outlet pipes separately

The patent document, publication number CN102563767A, application number 201210037660.8 discloses a multi-functional indoor air freshener coupled with purification and fresh air ventilation, which realizes the function of replenishing fresh air indoors by using the air duct connected to the outside, but there is no supplementary The air solves the problem of cold in winter and hot in summer, which increases the energy consumption of indoor air conditioners; there is no way to discharge indoor air to the outside, so it is difficult to reduce heavy pollution such as indoor smoke through rapid ventilation, and even the pollutants in the room will pass through the doors and windows Gaps, etc. into other rooms

In addition, in the process of exchanging the air outlet and inlet air in the existing total heat exchanger, in the cold winter, due to the use of heating or air conditioning, the indoor and outdoor temperature difference is large, and it is easy to generate condensation on the inner wall of the total heat exchange, which will block the air flow, and even Corrosion and damage to the inner wall material of the heat exchange core
