Intelligent total heat exchanger

Abstract

The invention discloses an intelligent total heat exchanger, wherein an air quality sensor can control the rotating speed of a fan; a fan speed setting machine can set the rotating speed of the fan at different times throughout the day, and can automatically control the rotating speed according to the time; an operation time accumulator can accumulate the whole machine starting time, can compare the whole machine starting time with the longest use time limiting value of a filter cotton pre-arranged in the controller, and controls the rotating mode of the fan according to the compared result; and the front-back pressure difference value of a pressure sensor is compared with the limit pressure difference value of the filter cotton pre-arranged in the controller, and an alarm is controlled to warn according to the compared result. The intelligent total heat exchanger can automatically control the rotating speed of the fan all day according to the living habits of general crowds, can monitor the indoor temperature and the outdoor temperature in real time, can automatically monitor the use time of the filter cotton and the sudden failure, and starts different rotating modes of the fan through monitoring the outdoor temperature to prevent the frost from forming on an impeller of the fan to cause unsmooth operation.

Description

technical field [0001] The invention relates to a total heat exchanger, in particular to an intelligent total heat exchanger. Background technique [0002] With the increasing airtightness of urban buildings, the increasing popularity of air conditioners and the diversification of building decoration materials, the air quality in people's daily life and workplaces is deteriorating day by day, which leads to people who have been in relatively closed spaces for a long time are prone to headaches. Stuffiness, nausea, shortness of breath and sore eyes and throat, so maintaining the convection between the air in the building and the outside air is very important to human health. Although at present many buildings (such as large public places, production workshops, etc.) are equipped with indoor and outdoor air convection devices, or air conditioners are used in residential buildings to achieve ventilation, the above-mentioned methods must be maintained when performing indoor and ...

Problems solved by technology

[0004] At present, in common total heat exchangers, the fan speeds of different gears are pre-set in the controller, and the fan speeds are controlled by manual buttons at different times and in different states. However, because the fan speed directly affects the exchange efficiency, and the indoor and outdoor temperatures , Indoor air quality conditions and people's different needs at different times of the day, etc. need to adjust the fan speed. If only manual button adjustment is used, it will increase the i...
