The box structure of the air handling unit

Abstract

The invention relates to a box structure of an air handling unit, which includes: a plurality of panels, the panels constitute the main body of the box structure, and the inner air inside the box structure and the air outside the box structure The outside air is isolated; a plurality of frame bars, each of which is of integral structure and arranged between two adjacent panels, each of the frame bars also has an inner side facing the inner air and an inner side facing the inner air The outer side of the outer air, as well as the joint corner and the fastening device, the joint corner is arranged at the intersection of a plurality of the frame bars, and the fastening device is used to fixedly connect the panel and the frame bar, wherein , at least a part of the outer side of the frame bars is covered by the panel, and one side of the inner side and the outer side of each of the frame bars is arranged not to be in contact with the air. The present invention has improved box performance and reduced material costs.

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
