Embodiment Construction

[0008] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, the present invention mainly includes a counter-rotating coaxial fan 1, a motor 2, a heat recovery device 3, a double-probe sensor 4, a sterilization filter 5, a controller 6, a fresh air passage 7, an exhaust air passage 8 and a frequency converter 9. The double-probe sensor 4 is used to detect the level of indoor carbon dioxide and smog concentration, and the speed of the fan 1 is adjusted through the controller 6 and the frequency converter 9 .

[0009] Two counter-rotating coaxial fans 1 are respectively located in the fresh air passage 7 and the exhaust air passage 8, a sterilization filter 5 is installed at the entrance 7 of the fresh air passage, and the heat recovery device 3 is bridged between the fresh air passage 7 and the exhaust air passage 8 In between, a double-probe sensor 4 is installed in the ex...

Abstract

An energy-saving automatic air exchanger is composed of two fans installed coaxially in different directions, heat recovering unit, dual-probe sensor, controller, frequency converter, sterilizing filter screen, fresh air channel and exhaust channel. The cold or heat of exhausted air can be recovered by heat recovering unit outdoor fresh air passes through above unit, and then returned back to room via fresh air channel. The rotation speed of fans can be regulated according to the concentrations of CO2 and smoke in room.

Description

Technical field: [0001] The invention relates to an energy-saving ventilator, in particular to an energy-saving automatic ventilator controlled by frequency modulation, and belongs to the technical field of energy conservation and environmental protection. Background technique: [0002] Because indoor air pollution seriously endangers human health, people often use ventilation methods, that is, use outdoor fresh air to dilute indoor polluted air so as to improve indoor air quality. Therefore, fresh air fans and ventilators have gradually become indispensable equipment for modern buildings. Among the existing technologies, the patent No. ZL00239273.9 for "Fresh Air Purification Ventilator" uses three-layer filtration to remove pollen, particles, bacteria and odors in the air. This patent aims to solve the problem of fresh air filtration, and does not involve energy-saving measures in the ventilation process. The patent No. ZL98115358 for the "energy-saving ventilator" paten...
