Stainless steel capillary capillary air conditioning

The capillary network is composed of capillary tubes with an outer diameter of 3.5-5.0mm (wall thickness of about 0.9mm) and water supply and return main pipes with an outer diameter of 20mm (wall thickness of 2mm or 2.3mm), which simulate the mechanism of veins and human capillaries. Heat insulation layer, heat dissipation layer, combined with capillary network, composite capillary network heat exchanger, greatly improve the heat dissipation capacity of capillary network single structure and use, protect the capillary tube wall from damage. Capillary net plane radiation air conditioning system generally adopts small circulation large system mode, and uses special solution as medium, can avoid system blockage, convenient control. To achieve higher comfort and avoid condensation, the room should also be equipped with humidity control and fresh air system. Capillary net production and application technology has been highly monopolized by German enterprises, Beijing Plaifu Environmental Technology Co., Ltd. has broken the monopoly of foreign enterprises, developed and produced domestic capillary net heat exchanger, applied for a number of invention patents and utility model patents, and has entered the stage of mass production. In May 2007, the product was tested in air conditioning Institute of China Building Research Institute (National Air Conditioning Equipment Grain Supervision and Inspection Center). Taking a node as an example, the results are as follows: 1. Under the experimental pressure of 1.5mpa, there is no leakage; 2. When the water supply temperature is 45℃, the return water temperature is 40℃, the reference temperature is 20℃, and △T=22.5℃, the heat dissipation per unit area of the sample Qdr=240.88W/m2; 3, in the water supply temperature of 15℃, return water temperature of 20℃, reference temperature of 26℃, △T8.5℃, equivalent to sample unit area cooling capacity Qdl=122.84W/m2.
