AI Technical Summary

Problems solved by technology

This kind of design idea needs to be equipped with complex water pipelines and radiators, which not only requires high investment, but also scale will affect the life of the equipment and the uniformity of heating. There are also certain problems in safety, and it can only realize the heating function, without the function of disinfection and reduction of PM2.5

[0004] CN105240898A discloses a phase-change heat storage heater, which utilizes the phase-change heat of phase-change materials for heat storage. The weight of the heat storage body, and directly heating the air, saves the water heat exchange link, simplifies the equipment, and still does not have the functions of reducing PM2.5 and disinfection

[0010] CN1602964A discloses a high-temperature disinfection and sterilization machine, which combines filtration, ozone generator, heating (electric heating tube or high-temperature smoke tube) disinfection, ultraviolet irradiation box , refrigeration and heating components, and activated carbon nets can theoretically improve the disinfection effect, but there are no corresponding improvement measures for the aforementioned problems and weaknesses of each technology, and the suitable temperature range of the heated air is not given. According to its structural characteristics, the temperature of the air being heated is likely to be lower than 800°C

At this time, the oxidation of a small amount of organic pollutants in the air may not be complete, resulting in incomplete disinfection, so its practicality remains to be seen.

[0011] CN1602965A discloses a combustion-type high-temperature disinfection and sterilization device. This invention proposes a heat exchange structure with simple structure and excellent performance, which utilizes high-temperature waste gas after combustion Heating the air to sterilize, while using the incoming air to absorb heat, reducing the exhaust temperature and saving energy consumption. It is suitable for air disinfection and instant heating. It has no heat storage function and is limited by the performance and service life of the double spiral material. , the temperature of the air being heated should not exceed 800°C

At this time, the oxidation of a small amount of organic pollutants in the air may not be complete, resulting in incomplete disinfection, and when the temperature is too high or the service life is reached, it is easy to form a mixture of combustion exhaust gas and sterilized air, resulting in more serious pollution

[0012] CN105674429A discloses a convection heater with air purification function, CN104474884A discloses a thermoelectric combined photocatalytic air cleaner, CN206018842U discloses a An air purifier with heating function, CN103807960A discloses a multifunctional air purifier; it also basically adds a heating function on the basis of the aforementioned existing air purification technology, which is suitable for air disinfection and instant heating, and does not have the ability to utilize low-peak electricity. Energy storage heating function

The slight disadvantage is that there are still no measures designed to prevent burns, scalds, and even fire accidents, and the heat storage capacity is also insufficient, and the outlet air temperature will be relatively high, which limits the amount of air treated at high temperature, and if the ozone concentration is too high If the ozone concentration is too high, the disinfection effect will decrease, and the ozone concentration will be secondary pollution.

[0016] In summary, the existing filtration, adsorption, ultraviolet light, photocatalysis, ozone and other air purification and disinfection technologies all have secondary pollution (pollution Accumulation of pollutants or bacteria on filter materials or adsorption materials, or new generation of a small amount of NOx, or high ozone concentration, etc.), complex use and maintenance, short life, etc.; in regenerative heating technology, little consideration is given to air purification
