Energy-saving ventilator device

Abstract

The invention discloses an energy-saving ventilator device. The energy-saving ventilator device comprises a single-chip microcomputer, a temperature acquisition module connected with the single-chip microcomputer, an alarm module relay and a ventilator connected with the relay, wherein the temperature acquisition module is used for collecting indoor and outdoor temperatures in real time and transmitting the collected indoor outdoor temperature to the single-chip microcomputer; the single-chip microcomputer judges the indoor and outdoor temperature, when the outdoor temperature is larger than apreset first temperature threshold value, or when the indoor temperature is larger than a preset second temperature threshold value, an alarm signal is output to the alarm module, and the alarm module receives and executes an alarm, meanwhile, the single-chip microcomputer performs differential operation on the indoor and outdoor temperature to obtain an indoor and outdoor temperature differencevalue, when the indoor and outdoor temperature difference value is smaller than or equal to the first preset temperature difference value, the air exchange fan does not work; when the indoor and outdoor temperature difference value is larger than or equal to the first preset temperature difference value and is smaller than or equal to the second preset temperature difference value, the air exchange fan works. According to the temperature exchange principle, the advantages of energy conservation are achieved.

Description

technical field [0001] The invention relates to the field of energy-saving control, in particular to an energy-saving ventilation fan device. Background technique [0002] Air-conditioning can keep a suitable temperature in the housing room, but air-conditioning requires a closed space, and people need to breathe, consume oxygen, and exhale carbon dioxide. As a result, in the closed space, the air quality drops, making people uncomfortable, so as to affect people's health. To solve this problem, you need to change the air. However, ventilation makes the indoor temperature energy loss, wasting energy. Contents of the invention [0003] The object of the present invention is to provide an energy-saving ventilating fan device. The present invention uses an energy exchange system to discharge indoor air to the outside and recycle the energy in the air to achieve cold and heat compensation. In winter, the recovered energy automatically heats the incoming fresh air; in summer...

AI Technical Summary

Problems solved by technology

Because the ventilation fan uses the principle of temperature exchange to achieve the purpose of energy saving and solve the problem that the traditional ordinary ventilation fan only performs the effect of exchanging indoor and outdoor air, and cannot reduce the temperature difference and energy loss of the exchanged gas.
