Balanced circulation system for confined space

Abstract

The invention discloses a balanced circulation system for a confined space, and belongs to the technical field of air circulation control. The balanced circulation system comprises a main unit, as well as exhaust pipes and return air pipes, which are communicated with the main unit, wherein the main unit comprises a first fan and a second fan, and the first and second fans are both controlled by a main control board; the exhaust pipes comprise horizontal exhaust pipes and vertical exhaust pipes, the horizontal exhaust pipes are laid on a ceiling of the confined space, and the vertical exhaust pipes are laid on the sidewall of the confined space; the return air pipes are laid on the ceiling of the confined space, and are parallel to the horizontal exhaust pipes. According to the balanced circulation system for the confined space, the exhaust pipes and the return air pipes are arranged on the ceiling and sidewall of a heat-preservation room in a balanced manner, so that balanced circulation of air in the heat-preservation room is ensured, dead angles in the whole room are prevented, and temperature and humidity in the room are kept constant.

Description

technical field [0001] The invention belongs to the technical field of air circulation control, in particular to a balanced circulation system in a confined space. Background technique [0002] Confined spaces with special purposes are widely used in scientific experiments and production, and can provide controllable conditions that are difficult to achieve in the natural environment. The gas flow in confined spaces is especially important, such as heat preservation rooms. People are used to air-drying and storing various foods. Food is easy to store and has a long shelf life. Existing heat preservation rooms generally use fans to air dry or heat to dry, but because the air circulation in the heat preservation room cannot guarantee to cover any corner, and it is difficult to keep the temperature and humidity at any position in the heat preservation room consistent, there are differences in the air-drying effect of preserved food.
