Novel solid adsorption dehumidifier

Abstract

The invention relates to a solid adsorption dehumidifier, which is characterized in that a finned tube formed by closely combining a tube and a fin is used as a substrate. The surface of the substrate is stuck with a silica gel absorption substance which is arranged in an air channel; the upper part and the lower part of the finned tube are both connected with cold and hot water pipes and corresponding valves which are communicated with cold and hot water sources respectively; the upper end of the air channel is provided with an exhaust port, an exhaust port valve, an air outlet, an outlet valve and a fan; and the lower end of the air channel is provided with an air inlet and an air inlet valve. The solid adsorption dehumidifier has the advantages that: 1, the fin and the finned tube are used as the substrate, so the solid adsorption dehumidifier has simple structure, easy marketization, high heat transfer efficiency and bearing capacity; 2, silica gel is used as the absorption substance, so that the solid adsorption dehumidifier has low regeneration temperature, and can use solar energy and geothermal energy; and 3, the fan is used for driving humid air current to flow through the surface of a silica gel layer, so the solid adsorption dehumidifier has good heat calorie exchange and dehumidifying effect.

Description

[0001] The invention relates to a solid adsorption dehumidification device, in particular to a solid adsorption dehumidification technology in which solar energy or geothermal energy is the heat source, and belongs to the fields of heat energy utilization and air conditioning and refrigeration. Background technique [0002] 1. In areas with sufficient solar radiation resources or geothermal resources, it is necessary to use solar energy or geothermal heat for building heating to save conventional energy. However, there is currently no cheap commercial device for how to efficiently use solar heat and geothermal heat for dehumidification and cooling in summer. Especially small devices. Adopt solar energy, geothermal energy absorption refrigeration [1] , not only need a cooling tower, high investment, complicated equipment, but also occupy a lot of land and waste water. If you do not use solar collectors in summer, you need to cover the sun, otherwise the collectors will be dama...

Problems solved by technology

[0003] 2. The existing solar energy and heat pump liquid dehumidification units have high regeneration temperature and are corrosive, and the equipment is also complicated and expensive [2]

Uneconomical for small buildings

[0004] 3. The existing rotary solid adsorption dehumidification units on the market are not only complex in structure, expensive, but also have high regeneration temperature, and need to use conventional energy steam for regeneration [3]
