Problems solved by technology

However, the operation mode of the conventional fresh air switch is relatively single, which cannot meet the diversified needs of customers. As a result, in addition to installing the fresh air switch, customers still need to install heaters, dehumidifiers and other air treatment in order to realize air conditioning functions such as heating and dehumidification. equipment

Abstract

The invention relates to a multifunctional fresh air exchanger comprising a fresh air mechanism and a dehumidifying mechanism. The fresh air mechanism communicates with the dehumidifying mechanism, and the fresh air mechanism is internally provided with a bypass device and a heating device and comprises a box body, a heat exchanging core body, an air exhauster, an air feeder, a fresh air isolating valve, an air exhausting isolating valve and an inner circulating air valve; the bypass device is arranged below the heat exchanging core body and communicates with an air returning cavity and an air exhausting cavity; the dehumidifying mechanism communicates with an air feeding port and comprises a crate and a dehumidifying system arranged in the crate; and the crate is further provided with an air outlet. The fresh air exchanger of the structure has four modes of the regular fresh air mode, the dehumidifying mode, the heating mode and the bypass mode, the modes can be flexibly switched according the indoor air condition, the indoor comfort degree can be kept, and the requirements of a user can be met.

Description

Technical field [0001] The invention relates to the technical field of air exchange equipment, in particular to a multifunctional fresh air switch. Background technique [0002] At present, the commonly used fresh air switch is mainly composed of a cabinet, a blower, an exhaust fan, a fresh air filter component, a return air filter component and a heat exchange core. When the unit is running, the outdoor fresh air is sucked in by the delivery machine, and the indoor return air is sucked in by the exhaust fan. The fresh air and return air are in the heat exchange core due to the difference in temperature and humidity, and energy is recovered from the return air side through the process of heat and mass transfer. To the fresh air side, the fresh air is then sent into the room through the blower, and the return air is discharged outside through the exhaust fan. However, the weather changes greatly throughout the year, leading to increasingly diversified customer needs. In addition ...
