Solid adsorption moisture eliminator based on semiconductor refrigeration

Abstract

The invention relates to a semiconductor refrigeration-based solid absorption dehumidifier and belongs to the technical field of air dehumidifiers. The dehumidifier is characterized by comprising a semiconductor cooler, a first solid hygroscopic agent adhered on a cold end of the semiconductor cooler for dehumidifying processed air and a second solid hygroscopic agent adhered on the hot end of the semiconductor cooler for regenerated air to carry away the water absorbed by the second solid hygroscopic agent. After a half period, under a condition of constant air ducts used by the process air and the regenerated air, the semiconductor cooler is rotated 180 degrees and the direction of the current in the semiconductor cooler is changed at the same time, or an air valve changes instead of the rotation of the semiconductor cooler. Meanwhile, the solid hygroscopic cooler can be adhered on the cold end and the hot end of the semiconductor cooler indirectly through the fin extended surface heat exchanger or a heat tube exchanger. A plurality of the dehumidifiers can be connected serially to form a multistage dehumidifier. The application has the advantages of greatly improving the efficiency of semiconductor refrigeration.

Description

technical field [0001] The invention belongs to the field of energy, especially the field of heating, ventilating and air conditioning. Background technique [0002] Dehumidification of the air is one of the main tasks of the air conditioning system in summer. Most of the existing dehumidification methods are based on condensation dehumidification, that is, a refrigerator (mostly an electric refrigerator with Freon as a refrigerant) is used to prepare low-temperature cold water, and the low-temperature cold water passes through the surface cooler to reduce the temperature of the air below the dew point Condensate moisture to achieve air dehumidification process. Because the required cold water temperature is very low, the refrigerator works at a low evaporation temperature, resulting in a low coefficient of performance of the refrigerator; although the air humidity after condensation and dehumidification meets the requirements, the temperature is too low, and sometimes it n...

Problems solved by technology

However, due to the rotation of the runner, it is difficult to realize the internal cooling of the dehumidification process and the internal heating of the regeneration process, so that the humidity of the air decreases during the dehumidification process, but the temperature increases, and the dehumidification process of heating significantly restricts the solid adsorbent (or The dehumidification capacity of the solid absorbent) also makes the regeneration temperature required by the solid adsorbent increase significantly. Generally, the regeneration temperature of the runner is 100-130°C
