Multi-mode full heat exchange fresh air system and control method thereof

Abstract

The invention provides a multi-mode full heat exchange fresh air system and a control method thereof. According to the multi-mode full heat exchange fresh air system, a fresh air outlet communicates with a fresh air inlet through a fresh air channel, a return air inlet communicates with an exhaust outlet through an exhaust air channel, and a fresh air draught fan and an exhaust air draught fan arecorrespondingly arranged in the fresh air channel and the exhaust air channel; the fresh air side of a full-effect heat exchange core body and the exhaust air side of the full-effect heat exchange core body correspondingly communicate with the fresh air channel and the exhaust air channel; the fresh air channel comprises a mixed air cavity, the mixed air cavity is provided with a dehydrating device, a fresh air valve and a return air valve, the fresh air valve is used for controlling the communication and the isolation between the fresh air inlet and the mixed air cavity, and the return air valve is used for controlling the communication and the isolation between the return air inlet and the mixed air cavity; and the fresh air draught fan, the exhaust air draught fan, the dehydrating device, the fresh air valve and the return air valve are all electrically connected with a control processor, and thus the switchover of different air adjusting modes is realized.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a multi-mode total heat exchange fresh air system and a control method thereof. Background technique [0002] The fresh air system is an effective air purification equipment, which can introduce fresh outdoor air into the room after filtering, heating and other processes, and can also discharge the dirty air from the room to the outside. With the advancement of science and technology, only filtering, ventilation The fresh air system with heat exchange and other functions cannot meet the needs of consumers. It is necessary to have a fresh air system that can adapt to different weathers such as rainy days, sunny days, and severe smog. It also needs a fresh air system that can adapt to different users in spring, autumn, winter and summer. It can always provide users with a clean and comfortable indoor air environment in an intelligent and energy-saving manner. Contents of the inventio...
