Heat recovery type dew point evaporation cooling enclosed water chiller unit based on corrugated tube heat exchange

Abstract

The invention discloses a heat recovery type dew point evaporation cooling enclosed water chiller unit based on corrugated tube heat exchange. The water chiller unit comprises a unit housing, wherein one lateral wall of the unit housing is provided with an air intake. A heat pipe evaporation section, a dew point combined evaporation cooling unit based on a corrugated tube, and a refrigerating unit based on an evaporation cooling coiled pipe are sequentially installed inside the unit housing according to the air flowing direction. The corresponding top wall of the unit housing above the dew point combined evaporation cooling unit based on the corrugated tube is provided with an air exhaust port a; a heat pipe condensation section is arranged above the refrigerating unit based on the evaporation cooling coiled pipe; and the top wall of the unit housing corresponding to the heat pipe condensation section is provided with an air exhaust port b. In the heat recovery type dew point evaporation cooling enclosed water chiller unit based on the corrugated tube heat exchange, a split-type heat pipe heat exchanger is combined with the dew point combined evaporation cooling unit based on the corrugated tube, and is combined with the refrigerating unit based on the evaporation cooling coiled pipe, thereby achieving the effective utilization of the exhaust air cooling capacity and the stepped cooling of the air, and accordingly increasing the refrigeration efficiency effectively.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to a heat recovery type dew point evaporative cooling closed-type chiller based on wave-jointed tube heat exchange. Background technique [0002] Most of the existing evaporative cooling chillers are simply composed of tube-type indirect evaporative coolers or air coolers and direct evaporative coolers. The water distributor in the device sprays water directly on the surface of the filler. When the air flows through the filler and exchanges heat and moisture with the spray water on the surface of the filler, the exhaust air with a lower temperature is directly discharged into the atmosphere, which is not properly utilized; In addition, because the filler is easy to absorb dust and impurities, the air flowing through the filler is in direct contact with the water for heat and moisture exchange, which makes the high-temperature cold wat...
