Abstract

The invention is discloses a fixed-point jet blowing system, having in turn fresh blast pipe, fresh blast valve, air processor, cold blast pipe, total valve of cold blast pipe, branch pipe of cold blast pipe, fixed-point control region, naturally ventilating branch pipe, total valve of naturally ventilating branch pipe, naturally ventilating fan, and naturally ventilating pipe, where the fresh blast pipe is connected with air exhausting valve, air return orifice and air return pipe through air return valve and air exhausting valve is connected with air exhausting pipe. Each fixed-point region can singly control the blowing temperature and speed and realize individual regulation, the fresh air can be directly fed to the head, ensuring the freshness, oxygen content and purity of the breathing air. The air flow adopts the form of bottom feed and top return, using hot air rising property to effectively discharge heat quantity and combustion (gas), thus enhancing the air quality in fixed-point control region and beneficial to health in body and mind of working personnel.

Description

technical field [0001] The invention relates to a fixed-point jet air supply system. Background technique [0002] The comfort of air conditioning is the result of the comprehensive influence of thermal comfort, oxygen content, odor, noise and air pollution, and the thermal comfort is related to the degree of human activity, thermal resistance of clothes, air temperature, air humidity, air flow velocity and Six factors such as the average radiant temperature are related. The original air-conditioning comfort only considers air temperature, air humidity and air flow velocity, and pursues a uniform temperature and velocity indoors to meet the comfort requirements of the staff in the office. In actual operation, it cannot well meet the needs of all staff. comfort requirements. In addition, due to the defects of the traditional system itself, unreasonable indoor air flow organization or insufficient fresh air volume, the pollutants (gas) generated i...
