A circumrotating adjustment individuation blast terminal apparatus of air-conditioner

Abstract

The rotary adjusting, personalized air conditioning air blast end device belongs to the heat air conditioning field. It features in the stair type rotary adapter between the wind blast end and reducing wind pipe, the conic section of the horizontal profile of the inner cavity of the wind blast end, and linear design of the longitudinal profile, with wind shroud equipped at each exhaust outlet of the wind blast end. It shows that the exhaust resistance at the wind blast end reduces obviously, driven by the 800mA / 12V small scale draught fan, average exhausting speed reaching above 4m / s, fairly enough to satisfy the air conditioner's demand for new wind volume. Meanwhile, the conic section of the horizontal profile and the linear design of the longitudinal profile of the exhaust end inner cavity and wind shroud for each outlet greatly reduce the flowed out exhaust, effectively lowering the wind blowing feel of the air conditioner user by playing the function of air diffusion.

Description

Technical field [0001] The patent of the invention relates to a personalized air-conditioning air supply terminal device, which belongs to the technical field of HVAC. Background technique [0002] The traditional mixed ventilation makes the indoor environment as uniform as possible. The supply air mixes with the surrounding environment before reaching the people's activity area. The improvement in the thermal perception of people and the surrounding air quality is poor. Research has found that the mixed ventilation is in a large area of ​​space. After the supply air is mixed with indoor air and polluted, only about 1% of the fresh air can be used. Although the newly developed displacement ventilation can provide better air quality and save energy at the same time, the vertical temperature gradient of the displacement ventilation room is relatively large. The airflow temperature near the ground is low, and the wind speed is high, which is easy to cause the feeling of blowing. Par...

Problems solved by technology

A Chinese invention patent application discloses a personalized air supply technology, that is, "Variable Air Volume Personalized Air Supply Device" (application number: 200510011652.6), which uses a booster fan to introduce fresh air into a variable-diameter air duct and passes through a stainless steel bellows It is sent from the plexiglass air outlet, but there are three shortcomings: the resistance of the stainless steel bellows is too large, the wind speed at the end is not enough, and it cannot provide enough air volume; the bending and shaping performance of the stainless steel bellows cannot meet the requirements, and it is difficult to freely adjust the air supply direction in practice; the shower head In order to meet the uniformity of air supply, the type air outlet needs to have a large volume, and it is not easy to disassemble after installation
