Modular radiation panel

Abstract

The invention discloses a modular radiation panel and belongs to end equipment of a central air-conditioning system, which can be used for cooling and heating of an air conditioner. The modular radiation panel mainly comprises a panel and an insulating layer, wherein the panel and the insulating layer are fixedly connected with each other; a sealed cavity is formed between the panel and the insulating layer; a capillary net grid is arranged in the cavity; and the capillary net grid is tightly contacted with the panel. Compared with the prior art, the modular radiation panel has the advantages of: 1) insusceptibility to dew formation on the surface of the radiation panel due to the uniformly distributed surface temperature; 2) light weight, convenient installation and modular production; 3) simple welding and convenient maintenance of the capillary; and 4) rapid installation due to the adoption of a standard connector.

Description

technical field [0001] The invention belongs to a terminal device of a central air-conditioning system and can be used for cooling and heating of air-conditioning. Background technique [0002] The radiant cooling (heat) air-conditioning system is a new type of energy-saving air-conditioning system. It mainly eliminates the sensible heat and waste heat in the room through radiation heat exchange. Natural cooling sources (such as groundwater or direct evaporative cooling water) are used in combination to greatly improve system efficiency and reduce system energy consumption. The fresh air is independently controlled to effectively ensure the freshness and humidity of the indoor air. The system has uniform indoor temperature, no blowing sensation, no noise, no condensation water hazards, and has extremely high comfort. It is a new trend in the development of air-conditioning terminals in the future. At present, this technology is widely used in Europe, and it is still in the ...

AI Technical Summary

Problems solved by technology

The system has uniform indoor temperature, no blowing sensation, no noise, no condensation water hazards, and has extremely high comfort. It is a new trend in the development of air-conditioning terminals in the future. At present, this technology is widely used in Europe, and it is still in the initial stage of research and application in China. Has few independent core technologies

The radiant panel is the key equipment of the system. At present, the radiant panel used in China is mainly a metal tube radiant panel. The cooling of the metal tube radiant panel is to exchange heat between the frozen water in the metal tube and the tube wall, and then transfer the cold energy to the metal panel ( That is, the ceiling board), the diameter of the metal pipe is generally 15mm, and the arrangement of the metal pipes on the metal plate is relatively sparse, which leads to uneven temperature distribution on the plate surface and easy condensation on the surface of the plate. In addition, the metal tube radiant plate still has manufacturing Disadvantages such as high cost, heavy weight, inconvenient installation, and difficult maintenance
