Fresh air and energy-saving controller and control method thereof

Abstract

The invention relates to a fresh air and energy-saving controller and a control method thereof. The controller comprises an air opening, an air duct, a fan, an electromagnetic valve and an intelligent control circuit, wherein the air opening, the air duct and the fan lead to the room and the outdoors, the electromagnetic valve and the intelligent control circuit are arranged on the air duct and used for opening and closing the air duct, the input end of the intelligent control circuit is connected with an outdoor atmospheric temperature sensor, one route of the output end of the intelligent control circuit is connected with the power control circuits of air conditioners, another route of the output end of the intelligent control circuit is connected with the power control circuit of the fan, and another route of the output end of the intelligent control circuit is connected with the electromagnetic valve. According to the outdoor temperature and the temperature set indoors, the controller and the control method for controlling the controller can automatically start and shut down each air conditioner according to requirements, and control the intake of the fresh air, and consequently, not only is energy saved, but also the indoor air can be kept fresh.

Description

technical field [0001] The invention relates to an energy-saving control device and a control method thereof, in particular to a fresh air energy-saving control device and a control method thereof. Background technique [0002] At present, commonly used indoor ventilation measures include window ventilation, ventilating fan ventilation or small household central air-conditioning ventilation, but these ventilation methods have their own shortcomings. The airflow caused by opening windows for ventilation is blind, and the turbulent airflow may bring the peculiar smell of the bathroom and kitchen into the living room and bedroom, entraining a large amount of outdoor dust, affecting indoor cleanliness, and it is impossible to avoid disturbing noise from the outside entering the room, and the bathroom shaft may produce Odor "backflow" phenomenon; the instantaneous exhaust air volume of the ventilation fan is large, and the indoor odor cannot be continuously removed. The ventilati...

Problems solved by technology

The airflow caused by opening windows for ventilation is blind, and the turbulent airflow may bring the peculiar smell of the bathroom and kitchen into the living room and bedroom, entraining a large amount of outdoor dust, affecting indoor cleanliness, and it is impossible to avoid disturbing noise from the outside entering the room, and the bathroom shaft may produce Odor "backflow" phenomenon; the instantaneous exhaust air volume of the ventilation fan is large, and the indoor odor cannot be continuously removed. The ventilation fan is easily damaged, and the maintenance cost will increase later. When the fresh air is introduced, the exhaust resistance increases, and the exhaust effect is not good; the small air conditioner has a return air outlet but cannot exchange with the outdoor air, and there is no exhaust, so it is difficult for the fresh air to be sent into the positive pressure area

A little fresh air cannot completely improve the indoor air quality, and the dirty air cannot be quickly discharged outside
