How to create a comfortable and comfortable living environment is a topic that everyone is very concerned about. Experts say that the first thing to do is to ensure that the indoor environment is conducive to good health. This promotes the prosperity of home central air conditioning and fresh air systems. Home central air conditioning is also in the frequency conversion innovation. Constantly meeting people's growing material needs.
The central air conditioner is mainly divided into two parts. The beginning is the central air-conditioning main unit, and the end is the indoor unit. The indoor unit is equivalent to a fresh air system, but in fact there is no function of the fresh air system. It can only be said that it is an advanced fan. In order to achieve the effect of fresh air ventilation, a central fresh air system must be installed, which can improve the air quality in the living room, keep the interior fresh and comfortable, and is good for health.
Many people feel that the bigger the fresh air system, the more comfortable it is. In fact, this is not the case. It is understandable that fresh air can greatly improve indoor air quality, but the greater the amount of fresh air, the better the effect of air conditioning. Experts believe that good air quality requires not only clean air, but also pleasant temperature and humidity. Although the central air-conditioning fresh air system improves the air freshness, it also increases the cooling and heating load of the air conditioner, which not only affects the air conditioning effect, but also greatly increases the power consumption. So how to design the fresh air system is reasonable, let's look at the design specifications of the central air conditioning fresh air system.
The value of the large central air-conditioning fresh air system in China is as follows: firstly, according to the new air volume of 30m3/h per person, the air exchange rate is calculated according to the number of air exchanges stipulated by different construction purposes, and then the two are taken as the final. The amount of fresh air, the amount of fresh air for home central air conditioners, has been specifically regulated in developed countries.
Experts pointed out that the fresh air volume of the central air-conditioning fresh air system should be no less than 20m3/(hw). When designing the central air-conditioning fresh air system, there are three factors that determine the size of the fresh air:
(1) Install the community environment in which the family is located and the geographical conditions in which it is located. If the environment is comfortable and clean, ventilation is good, and the design of fresh air volume can be reduced;
(2) Floor height. Since reducing the concentration of pollutants is the main purpose of installing a fresh air system, such as installing a home with a higher floor, especially above the 10th floor, the air is relatively clean, which can reduce the design of fresh air volume;
(3) Special requirements of customers. Some customers have their own unique lifestyle habits, such as smoking and so on.
Nowadays, most central air-conditioning installations are equipped with fresh air systems. The fresh air system itself is not very expensive. Coupled with the magical function of the new air system to vent new and turn waste into treasure, many home users will choose to install a central air-conditioning fresh air system to save energy and electricity. Add a comfort and tranquility to life.
