<p>A pre-dehumidifying evaporative cooler comprises a housing (7), a wind inlet (1), and a wind outlet (2). A wind outlet fan (118) is disposed at the wind outlet (2). A dehumidifying refrigeration device is disposed at the wind inlet (1). A humidifying refrigeration device is disposed at the position at the inner side of the wind outlet fan (118). The dehumidifying refrigeration device dehumidifies new wind through spraying a LiCl solution, and lowers the temperature of the new wind through the heat transfer of a thermal pipe (126), thereby implementing dehumidification and temperature reduction. The humidifying refrigeration device performs secondary humidification and temperature reduction through water spraying. The pre-dehumidifying evaporative cooler adopts a structure that combines dehumidification and refrigeration and a two-level refrigeration structure, thereby eliminating the limitation effects on the evaporative cooler by high humidity, which has a desirable refrigeration effect even in high temperature, high humidity regions, and is especially applicable to refrigeration for telecommunications rooms, data rooms, and other dedicated rooms that require cooled air all around the year.</p> |
