Box structure of air handling unit

Abstract

The invention relates to a box structure of an air handling unit. The box structure of the air handling unit comprises a plurality of panels and a plurality of frame strips. The panels constitute a body of the box structure, and inner side air in the box structure and outer side air outside the box structure are isolated. Each frame strip is of an integrated structure and is arranged between two corresponding adjacent panels. Each frame strip is further provided with an inner side facing the inner side air, an outer side facing the outer side air, a connecting corner and a fastening device. The connecting corners are arranged at the intersection positions of the frame strips, and the fastening devices are used for fixedly connecting the panels and the frame strips. At least parts of the outer sides of the frame strips are covered by the panels, and one side of the inner side and the outer side of each frame strip is arranged to be not in contact with the air. The box structure of the air handling unit has the advantages of improving the box performance and lowering the material cost.

Description

technical field [0001] The invention relates to an air handling unit (AHU), in particular to a box structure of the air handling unit. Background technique [0002] Air handling unit (AHU) is a centralized air handling system, generally equipped with various components such as fans, heaters, coolers and filters, which are used at the end of the entire air conditioning system. Box performance is an important indicator of air handling units, including heat transfer coefficient, cold bridge factor, etc. Improving the performance of the cabinet, thereby reducing the heat loss through the cabinet, has always been the focus of various manufacturers. Generally speaking, a box is assembled from several panels made of insulating material, so when there is a defect in the panel-to-panel connection, energy loss will result. The following is a typical box structure, see figure 1 , which includes a panel 1', an edge frame 21' and a middle frame 22'. The connection between the edge fr...

Problems solved by technology

In order to prevent the generation of the cold bridge, a layer of PVC plastic strip 5' is pasted on the inner side of the frame bar, that is, the part that contacts the air inside the box body. The purpose is to prevent the inner side of the frame bar from directly contacting the air inside the box body. The application of PVC plastic strip 5' cannot completely cut off the heat transfer between the air inside the box and the air outside the box through the frame strips

In addition, the bolt 41' as a metal part is fastened through the entire panel 1', so a cold bridge will be generated at the bolt 41', and energy will be transmitted along the bolt 41', resulting in a large amount of heat loss
