Energy-saving environmentally-friendly ventilator

Abstract

The invention relates to air heat exchange-type ventilation system equipment capable of purifying outdoor air and belongs to an energy-saving environmentally-friendly ventilator. The ventilator comprises a box body, wherein the inside of the box body is provided with an air supply pipe leading air from the outside to the inside of a room and an exhaust pipe leading air from the inside to the outside of the room; the exhaust pipe and the air supply pipe are crossed to form a core of a heat exchanger and are provided with air exchange fans and filter cotton respectively; the inlet end of the air supply pipe is provided with a temperature sensor; the outlet end of the air supply pipe is provided with an ultraviolet lamp; and the air exchange fans, the temperate sensor and the ultraviolet lamp are electrically connected with a controller. The ventilator has the advantages that: the structure has filtrating and sterilizing functions and effectively improves air quality; and 2, when the outdoor temperature is low (particularly below freezing point), air passing through the heat exchanger absorbs heat and brings part of heat back to the inside of the room, so heat loss is reduced.

Description

technical field [0001] The invention and the ventilation system equipment capable of purifying outdoor air and exchanging air heat specifically belong to an energy-saving and environment-friendly ventilation machine. Background technique [0002] When most people stay in a narrow space such as an office or a vehicle, they should take a breath at any time. At this time, we usually use the ventilation system equipment. [0003] Most of the current ventilation system equipment uses a blower to force the indoor air to be discharged to the outside, but when using a blower to only force the indoor air to be discharged, the cold or hot air in the room is not filtered. The outdoor air is directly discharged from the bottom, and the outdoor air flows in without filtering through the door or window cracks, which fails to improve the air quality, and the cold or hot air flows from the outside to the inside, causing a sharp change in the temperature of the indoor air. It makes people f...

Problems solved by technology

The above-mentioned structure has disadvantages: the system only has the function of filtering but not sterilizing. When the outdoor temperature is low (especially freezing), the cold air is directly discharged into the room, causing serious heat loss in the room.
