Abstract

The invention relates to a self-cooling type multi-stage evaporation and refrigeration method, and belongs to the field of air conditioning, energy conservation and environmental protection. According to the invention, the multi-stage indirect evaporation and direct evaporation processes are combined, and temperature of supply air is gradually reduced to the design state; the evaporation and refrigeration efficiency is greatly improved, temperature of the supply air is lower than the initial wet bulb temperature and approaches to the initial air dew point temperature; the refrigeration energy efficiency ratio reaches to 40 kw/kw, and the multi-stage indirect evaporation wet bulb efficiency reaches to 110%; the multi-stage combined evaporation wet bulb efficiency reaches to 130%, and supply air can be adjusted to humidification-free model or little humidification mode as per the use requirement; and the difficult problem of mass humidification in the single direct evaporation and refrigeration technology is effectively solved, and a novel energy-saving and environment-friendly approach with circulatory and reproducible energy is provided for the evaporation and refrigeration field.

Description

technical field [0001] The patent of the invention belongs to the fields of air conditioning, energy saving and environmental protection, and in particular relates to a self-cooling multi-stage evaporative refrigeration system and method. Background technique [0002] The existing direct evaporative cooling technology generally has defects such as low cooling efficiency, low wet bulb efficiency of supply air temperature, and large amount of humidification. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and provide a self-cooling multi-stage evaporative refrigeration system and its refrigeration method, which can superimpose multi-stage indirect evaporation and direct evaporation processes together, so that the temperature of the air supply is gradually reduced until it reaches The design status, evaporative cooling efficiency is greatly improved, and the air supply can be adjusted to no humidification or ...
