Problems solved by technology

They use the air outlet to supply air to the surroundings in a horizontal direction, which is closer to the human body, and the ankle of the human body is one of the more sensitive parts of the human body. In order to prevent the feeling of blowing, the air supply speed must be controlled to be low. Therefore, the maximum cooling and heating load that can be handled is limited
At the same time, the lower air supply speed makes the air supply momentum smaller, so that the air supply distance is shorter, and the air conditioning effect on the rear of the heat source is poor

Abstract

The invention discloses an adjustable air conditioning and supplying device at a seat end. The device comprises an air supplying upright post and is characterized in that: the outer diameter of the air supplying upright post is provided with a sliding block; the outer diameter above the air supplying upright post is connected with a hood through a support; the periphery of the hood is respectively connected with air flow conditioning rods through first bearings which are arranged uniformly; flexible air flow conditioning plates are fixed on the air flow conditioning rods; a conditioning bracket is connected between each air flow conditioning rod and the sliding block, wherein the conditioning brackets are connected with the air flow conditioning rods through second bearings; and the conditioning brackets are connected with the sliding block through third bearings. The air outlet of the device supplies air downwards uprightly, so that the air supply height is reduced so as to avoid blowing feeling of ankles; and the air flow of the horizontally supplied air is lower, and higher air supplying speed can be adopted, so that the quality of an air conditioning area behind a heat source is effectively improved.

Description

technical field [0001] The invention relates to an air conditioning air supply device, in particular to an adjustable air conditioning air supply device which can be used for air supply at the end of a seat. Background technique [0002] The purpose of indoor air conditioning is to change the thermal comfort of the indoor environment, improve the air quality, and improve the work efficiency and health of workers. Mixed ventilation and displacement ventilation are currently the most used air conditioning methods. The ventilation efficiency of mixed ventilation is lower than 50%, and the energy consumption is large, and the quality of the air reaching the human working area is deteriorated due to mixing. The theoretical ventilation efficiency of displacement ventilation driven by buoyancy control is higher than 50%. Since this ventilation method sends fresh air directly into the work area, a layer of air area with a certain height and completely composed of fresh air is forme...
