Problems solved by technology

The main disadvantages of this system are: one more fresh air system than the original air-conditioning system, which makes the system structure complex and increases the cost; in addition, more fresh air ducts should be reserved for the building structure, which increases the complexity of the building and affects the beauty of the building, making it inconvenient to promote and use; In addition, the fresh air volume can only be adjusted to improve indoor comfort, and the fresh air volume cannot be adjusted according to the combination of indoor temperature, humidity and carbon dioxide, which cannot guarantee health requirements
The main disadvantages of this device are: complex structure and high cost; the fresh air adjustment door is installed in the housing, and the fresh air volume can only be adjusted manually, which is inconvenient to operate and increases the difficulty of installation and maintenance; The space occupied by the central air-conditioning system has higher requirements for buildings; in addition, it can only ensure indoor comfort, but cannot guarantee indoor air health requirements

Abstract

The invention discloses an intelligent fresh air control device, which relates to a fresh air conditioning device of an air conditioning system. The intelligent fresh air control device mainly comprises a temperature humidity sensor, a carbon dioxide concentration sensor, a computer controller, an electrically operated valve and the like. The intelligent fresh air control device has the characteristics of intelligent control, convenient use, accurate control, energy-saving operation, small volume and low cost. And the intelligent fresh air control device also has the characteristics of improving the indoor air quality and meeting requirements of people for the indoor comfort and health. The intelligent fresh air control device can be widely applied to the air conditioning systems of various buildings such as residences, hotels, public buildings and the like and is the fresh air device which is controlled intelligently and saves energy.

Description

1. Technical field: [0001] The invention belongs to the technical field of air conditioning for building ventilation, in particular to a fresh air regulating device for an air conditioning system. 2. Background technology: [0002] With the development of the economy and the improvement of living standards, people have higher and higher requirements for air quality. Since people spend nearly 90% of their time indoors, indoor air quality has a very important relationship with human health, and the indoor fresh air volume is an important factor in determining indoor air quality. However, with the use of air conditioners, the problem of indoor air pollution is becoming more and more serious, and more and more people pay more and more attention to it. [0003] In addition, according to incomplete statistics, my country's building energy consumption has reached 27.5% of the total energy consumption, and this figure will continue to increase with the rapid development of my count...
