Problems solved by technology

[0003] Although the existing modular radiant panel can make the surface temperature distribution of the radiant panel uniform, its structural characteristics inevitably have a very thick air layer. This ultra-thick air layer increases the heat transfer resistance and greatly reduces the power supply of the radiant panel. cold capacity

Embodiment Construction

[0024] Such as figure 1 , 2 As shown, the radiant plate in Embodiment 1 of the present invention includes a metal panel 1 and a channel 7, wherein the channel 7 is made by welding a metal tube 5 with a semicircular cross section on the heat conducting plate 2, and the heat conducting plate 2 is very close to the metal panel 1. But it is not in contact with the metal panel 1, and a uniform air thin layer with a thickness of less than 1 mm is formed in the middle. The channel 7 and the heat conducting plate 2 are covered with an insulating material 3 . A support grid 6 is laid on the upper surface of the metal panel 1 . The support grid 6 is made of a material with poor thermal conductivity and is not easy to conduct heat. The heat conducting plate 2 is erected on the support grid 6 .

[0025] The metal pipe 5 has a semicircular cross section and is welded to the heat conduction plate 2 by welding process to form a chilled water flow and heat exchange channel. The heat transfe...

Abstract

The invention discloses a moisture condensation resistant radiant panel and a manufacturing method thereof. The radiant panel comprises a metal decking, a heat conducting plate, passageways, a supporting grid and heat insulating materials; the lower surface of the metal decking is coated with hydrophobic materials, and the upper surface of the metal decking is coated with a coating capable of improving the emissivity; the passageways are formed by welding to the heat conducting plate by copper plates, cross sections of the copper plates are semicircular, and a heat transfer area is large; the heat conducting plate is located between the metal decking and a heat insulating layer, the heat conducting plate is separated form the metal decking by the supporting gridding, and an air layer which is less than 1 mm in thickness is formed; the radiant panel has a cooling capacity which is equal to the common radiant panel. In addition, the air layer in the radiant panel can distribute the temperature on the surface of the metal decking evenly, a low temperature strip shape area is prevented from forming, and the moisture condensation resistant capacity of the radiant panel is highly improved.

Description

technical field [0001] The invention relates to a terminal device of a central air-conditioning system, in particular to a new anti-condensation radiation plate and a manufacturing method thereof. Background technique [0002] In the existing radiant panels, the heat exchange copper pipes through which chilled water circulates are in direct contact with the metal panels, and low-temperature strip-shaped areas are easily formed at the contact positions during operation. When the temperature in these low-temperature areas is lower than the dew point temperature of the indoor air, the water vapor in the air is easy to condense in these areas to form water droplets. During the operation of the radiant air conditioning system, the relative humidity of the indoor air changes greatly with the indoor personnel and the opening and closing of doors and windows, which leads to an increase in the dew point temperature of the indoor air and condensation on the radiant panel. Condensatio...
