Abstract

The invention discloses a heat exchange ventilating fan. The heat exchange ventilating fan comprises multiple isolating walls. The isolating walls are arranged in parallel from one side of the heat exchange ventilating fan to the other side of the heat exchange ventilating fan. A sealing cavity is defined by every two adjacent isolating walls to serve as an air outflow cavity or an air inflow cavity. Multiple air outflow cavities and multiple air inflow cavities are formed among the isolating walls and arranged at intervals. The air outflow cavities communicate with one another to form an air outflow channel allowing indoor air to be discharged out of a room. The air inflow cavities communicate with one another to form a fresh air inflow channel allowing outdoor air to enter the room. The isolating wall on the outermost side and the isolating wall on the innermost side of the heat exchange ventilating fan are each provided with air outflow holes allowing the indoor air to be discharged out of the room and fresh air inflow holes allowing outdoor air to enter the room. The air outflow holes communicate with the air outflow channel, and the fresh air inflow holes communicate with the fresh air inflow channel. By the adoption of the heat exchange ventilating fan, heat or cold energy in the building room can be stored effectively in the ventilation state, and energy saving is facilitated.

Description

technical field

[0001] The invention relates to the technical field of buildings, in particular to a heat exchange ventilation fan. Background technique

[0002] In order to ensure the health of people working and living in the building, the building is required to have a good ventilation effect, and the existing buildings generally realize the ventilation effect by setting opening fans on the windows. For existing traditional windows, the opening fan must be opened when ventilation is realized, so as to realize ventilation inside and outside the building. There are following defects in this ventilation mode:

[0003] 1. Outdoor dust is easy to enter the building through the open opening fan, polluting the air environment in the building, especially in sand, rain and snow, and spring weather, etc. Outdoor dust, rain and snow And external dirt such as floating catkins can easily enter the room and pollute the indoor air environment. If the fan is closed, the indoor ventilat...
