The lack of energy and the rapid changes in the global environment have made everyone pay more and more attention to energy conservation and environmental protection.
Energy conservation and environmental protection began to enter all walks of life and became the darling of the new era. In the HVAC industry, energy conservation and environmental protection have also become an industry trend.
With the severity of environmental protection problems, building energy conservation has also received more and more attention from various countries. As a major energy consumer of office buildings and residences, HVAC systems have a direct impact on the energy consumption of the entire building. Therefore, the development of HVAC has attracted much attention.
Heating, ventilation and air conditioning (HVAC) refers to the system or related equipment responsible for heating, ventilation and air conditioning in the room or car.
HVAC systems are designed to apply to thermodynamics, fluid mechanics and fluid mechanics, and are an important subdiscipline in the field of mechanical engineering.
HVAC includes heating, ventilation, and air conditioning technologies.
Heating: Also known as heating, it refers to providing heat to a building and maintaining a certain indoor temperature.
Ventilation: The process of sending and removing air into and out of a space by natural or mechanical means.
Air conditioning: referred to as air conditioning, is to meet the requirements of production and life, improve labor health conditions, and use artificial methods to make the air temperature, relative humidity, cleanliness and air flow speed of the room or confined space and other parameters meet certain requirements.
With the improvement of people's living standards, new energy-saving, comfortable and healthy air conditioning operation methods have gradually been respected. For HVAC systems, the comfort level of their application depends on a combination of factors such as wind speed, humidity, air humidity, average ambient radiant temperature, and people's perception of the environment.
Therefore, the selection of different combined environmental parameters produces different thermal comfort effects
Depending on the hot and humid environment, the energy consumption generated by the air conditioning system is also different. In winter, if the traditional air conditioning method is chosen to increase the indoor temperature, the heat and humidity exchange is carried out through the air in the human body and the environment, and the air humidity required is higher, in this case, the heat loss of heating fresh air and the heat loss of the maintenance structure are relatively large; If you can apply the new hot and humid environment application results, optimize the selection of air conditioning operation mode, improve the radiant heat, you can significantly reduce air humidity, generally 12 ° C ~ 24 ° C is appropriate, and the traditional air conditioning operation mode needs to be 18 ° C ~ 20 ° C, obviously the new air conditioning operation mode of energy saving effect is more objective.
Similarly, when using air conditioning systems in summer, the new air conditioning operation mode is more applicable. By applying this healthy, comfortable and energy-saving new air conditioning operation mode, it can not only meet the needs of high-level living, but also achieve the goal of energy conservation and emission reduction, which is consistent with the development of low-carbon economy.
