Description

Ventilation controllable gravity cabinet air conditioning device

The current air conditioner is popularized, but the common air conditioner has strong blowing feeling and larger noise, and the use comfort is influenced. The noise of the common air conditioner is mainly generated during ventilation, namely, when a fan runs, the noise is generated along with the flow of wind.

The gravity cabinet is a cabinet type air conditioning equipment which utilizes the natural convection principle to supply cold, heat and dehumidify, mainly depends on the change of air density caused by the heat exchange between cold (or hot) water in the internal capillary tube and the air outside the tube, thereby causing the natural convection of the air to generate natural air supply, realizing the supply of indoor cold (or hot) quantity, having the indoor air speed lower than 0.2m/s, having no blowing sense and noise, greatly enhancing the comfort, and having no limit to the low limit value of cold water temperature during cold supply.

However, the conventional gravity cabinet simply depends on natural convection and panel radiation to supply cold/heat, so that the indoor cooling/heating speed is slow, the required cooling/heating time is long, and the requirement of comfort of people in the starting process of the indoor air conditioner is difficult to meet to a certain extent.

In addition, conventional gravity cabinet, when water supply temperature was lower, the condensation that its panel surface produced can follow person's panel drippage ground, along with the increase of gravity cabinet operating duration, will form ponding on ground, and then influence service environment.
