Example Embodiment

[0039] Such as figure 1 , 2 As shown in 4, the energy-saving ventilation device of an embodiment of the present invention includes a hollow housing 10 in which a heat exchanger and a fan 20 are installed; the fan 20 is used to transport fresh air and discharge turbid wind. The energy-saving ventilation device can be used in indoor spaces that require ventilation, such as bedrooms, living rooms, offices, and so on. The fresh air source can be any outdoor space or other occasions where fresh air can be provided. It is delivered to the room through the fan 20 to provide fresh air for the room, while the stale air in the room can be directly discharged to the outdoor space through the fan 20 to prevent the turbid wind from being re-inhaled , To achieve indoor ventilation.

[0040] Such as figure 2 , 3 As shown, the heat exchanger includes at least one heat exchange core 30. When fresh air and turbid wind flow through the heat exchange core 30, heat exchange is performed to realize e...

Abstract

The invention relates to an energy-saving air exchange device. The energy-saving air exchange device comprises a shell, a heat exchanger and a draught fan, wherein the heat exchanger is arranged in the shell, the draught fan is used for conveying fresh air and discharging foul air, the draught fan comprises a draught fan shell, a driving mechanism which is arranged in the draught fan shell, a fresh air wind wheel and a foul air wind wheel, and the fresh air wind wheel and the foul air wind wheel are isolated from each other and are respectively arranged at two sides of the driving mechanism; a heat exchange fresh air inlet, a fresh air heat exchange flow passage, a heat exchange fresh air outlet, a shell fresh air passage and a shell fresh air outlet are sequentially communicated for forming a fresh air passage, and a shell foul air inlet, a shell foul air passage, a heat exchange foul air inlet, a foul air heat exchange flow passage and a heat exchange foul air outlet are sequentially communicated for forming a foul air passage; the foul air passage is isolated from the fresh air passage. According to the energy-saving air exchange device disclosed by the invention, the structure is compact and reasonable, and the energy-saving air exchange device is beneficial for reducing the size of a device.

Description

technical field [0001] The invention relates to a ventilation device, and further relates to an energy-saving ventilation device for indoor and outdoor air heat exchange and ventilation. Background technique [0002] In some indoor occasions (such as some bedrooms, living rooms, offices, etc.), ventilation is required to keep the indoor air fresh. Some conventional practices are to directly introduce fresh air and discharge indoor dirty air. When the indoor turbid wind is discharged, it will often take away the indoor cold air or heat, causing the indoor temperature to rise or fall, thereby increasing the load of the indoor air conditioner and consuming energy. [0003] For this reason, there have been some energy-saving ventilation devices applied indoors, which usually include an outer shell and a heat exchange core installed in the outer shell. In addition, a fan is installed on the shell to drive air flow, and heat exchange is performed through the heat exchange core t...
