Energy-saving window or door with bidirectional heat preservation aeration and air purification functions

Abstract

The present invention relates to an energy-saving window or door with bidirectional heat-preserving air change and air purification functions. The energy-saving window or door can realize bidirectional heat-preserving air change when being closed, not only discharging the polluted indoor air but also bringing the purified outdoor air into the room, and moreover, in the process of air change, an air heat exchanger arranged in a window frame or a door frame can carry out the sufficient redemption of heat and humidity between the indoor air and the air brought in from the outside in order to ensure that the indoor temperature and humidity cannot be changed. In addition, if flu or SARS is rampant, the energy-saving window or door can be switched from the bidirectional air change mode to an indoor air circulation mode, the indoor air circulation mode utilizes titan apatite and luminous optic semiconductor catalyzer loaded in a photocatalytic sterilization unit arranged in a third air chute to actively and dynamically sterilize and purify the indoor air, the sterilization rate can reach 99.9 percent, and thereby, the health of the human body can be protected. Furthermore, the energy-saving window or door can use the power provided by a photovoltaic cell, thus realizing energy saving and emission reduction.

Description

technical field [0001] The present invention relates to a window or a door, in particular to a window or door that can discharge indoor polluted air to the outside of the room, and at the same time introduce the outdoor air into the room after being filtered and purified, and by purifying the indoor air. An energy-saving window or door with two-way heat preservation and ventilation and air purification functions for dynamic sterilization treatment. Background technique [0002] The "World Health Report 2002" published by the World Health Organization (WHO) clearly listed indoor air pollution as one of the top 10 threats to human health. About 68% of human diseases are related to indoor air pollution. Indoor air pollution threatens human life, increases population mortality, and reduces human life expectancy for nearly ten years. According to statistics, about 111,000 people die from indoor air pollution every year in China. 80% of the homes of children with leukemia have b...

Problems solved by technology

[0003] At present, there are two main ways to solve indoor air pollution. One is to use indoor air purification equipment. This equipment mainly achieves the purpose of purifying indoor air by filtering, decomposing or absorbing harmful substances in indoor air. There are thousands of air pollutants, and the filtration or adsorption capacity of the filter device in this air purification equipment is limited, and it is easy to be saturated. With the deposition of pollutants, the purification effect is obviously reduced. In addition, due to the indoor Polluted air rises with hot air. Therefore, pollutants generally stagnate in the upper space of two-thirds of the floor height indoors. People's breathing range happens to be in this area, but indoor air purification equipment is generally placed on the table. Or underground, it is difficult to effectively purify the polluted air in this area. Moreover, the price of this kind of indoor air purification equipment is also expensive and not universal.

The second is to ventilate through windows or use ventilation equipment to ventilate. However, the use of these two methods of ventilation has the following disadvantages: (1) the original temperature and humidity in the room cannot be guaranteed during the ventilation process, especially in winter. This is especially true in heating rooms and air-conditioned rooms in summer; (2) the heat of the indoor air is discharged outside the room without exchange, causing a large amount of energy loss, which is not conducive to energy saving and emission reduction; (3) in places with large dust or serious pollution On the contrary, this kind of ventilation in the city is likely to cause new indoor air pollution and noise pollution; (4) Ventilation equipment generally has high energy consumption and high noise, and after installation, it affects the overall appearance of the room

Even the new fresh air system generally has the shortcomings of high price and use cost. Therefore, a low-cost technical solution that overcomes the above-mentioned shortcomings and comprehensively solves indoor air pollution is needed.
