Heat pipe type ventilation and heat recovery device

Abstract

The invention relates to a heat pipe type ventilation and heat recovery device, and belongs to the technical field of ventilation equipment. When the indoor air is dirty and the pollutant concentration is high, an indoor exhaust fan is started, and after the indoor air is entered into heat recovery core bodies, an outdoor exhaust fan is started to enable the outdoor air to flow into a room to sendfresh air; and a hot fluid and a cold fluid pass through an exhaust passage and an air inlet passage in a circulated mode to form an air replenishment and exhaust cycle, and after a plurality of airreplenishment and exhaust cycles are performed, the fans stop operating when the indoor pollutant concentration is reduced to a certain value. The heat pipe type ventilation and heat recovery device promotes the popularization of energy-saving and consumption-reducing devices, and satisfies the requirements of comfort, energy saving and intelligence; and a complete machine of the heat pipe type ventilation and heat recovery device is installed on an indoor wall, the appearance of the room is not affected, drawing of a curtain is not affected, the cost is low, automatic adjustment is achieved,the occupied space is less, the structure is simple, the operation is convenient, outdoor dust and noise pollution are avoided, indoor air quality is improved, and the purpose of energy saving is achieved.

Description

technical field [0001] The invention relates to a heat pipe type ventilation heat recovery device, which belongs to the technical field of ventilation equipment. Background technique [0002] Since the world energy crisis in the early 1970s, some industrially developed countries have widely used air heat recovery technology as one of the energy-saving measures in the air-conditioning industry. my country also began to develop sensible heat and total heat exchangers in 1979. At present, small energy-saving ventilation devices have been used abroad to a certain extent, but they are not widely used. In China, it is only used in some foreign-funded industrial and civil cleaning projects, and has not been widely used in HVAC systems. In recent years, ventilators have been gradually applied in China, and are used in non-residential non-residential small cabinet or split air conditioners without ventilation, while residential ventilators are based on the small residential space a...

Problems solved by technology

[0005] The main technical problem to be solved by the present invention is that the heat exchange efficiency of current ventilation equipment at home and abroad is relatively low, and it is difficult to achieve constant temperature ventilation, and the long-term start-up will cause the room temperature to change too much, and the ventilation equipment will destroy the layout of the house , affect the appearance of the building, and the function of the ventilation equipment is single, only ventilation can be achieved, and the indoor air cannot be adjusted in any way. The invention provides a heat pipe type ventilation heat recovery device
