Roof-distributed multi-air-port synergistic individualized air supply method and air supply system

Abstract

The invention relates to the technical field of air conditioning, and discloses a roof-distributed multi-air-port synergistic individualized air supply method and an air supply system. The air supplymethod comprises the following steps of determining an extremity action radius Rw of a single independent air port and a coverage radius Rs during independent use; setting the layout of air ports; fitting a relation between air supply parameters of the air ports, the indoor environment temperature, actual air supply parameters, the distances d between users and the air ports and thermal preferences TP of the users according to multiple example results simulated by CFD; dividing the interior of a room into three kinds of areas; measuring positions of the users and partition types to which the users belong; determining the thermal preferences TP of the users; judging whether or not multiple users exist in each area, and if yes, regarding the users with low TP values as objects; determining the distances d between the users and the acting air ports; determining the air supply flow and air supply angle of each air port, implementing the decision through a control system, and conducting comfortable air supply meeting the individualized thermal preference requirements of the users. By means of the roof-distributed multi-air-port synergistic individualized air supply method and the air supply system, a comfortable environment is quickly provided, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and in particular to a roof distributed multi-tuyere cooperative individualized air supply method and an air supply system. Background technique [0002] In recent years, the air-conditioning air supply method based on the thermal comfort of the human body has gradually become a new development direction of the air-conditioning system. Most of the existing air-conditioning systems pursue universality, and mostly take the average value of the demand feedback of the general public as the regulation target, while ignoring the large differences in heat preferences among individuals. Therefore, in order to achieve the ultimate goal of personalized air conditioning regulation, it is very important to effectively monitor the user's physiological parameters related to thermal sensation and accurately determine the degree of individual thermal preference. [0003] On the other hand, because the ...

Problems solved by technology

[0005] To sum up, the existing air-conditioning system lacks the distinction of individual differences, and generally needs to regulate the thermal environment of the entire room through high-power output to act on users, and the correspondingly designed station air-conditioning system has the limitation that the control area is not easy to change sex

At the same time, the above-mentioned existing patents all start from the overall system operation method, and the way of horizontal air supply limits the role of positioning air supply
