Abstract

The invention discloses an evaporation-type condenser based on dew point indirect evaporation cooling and pre-cooling. The evaporation-type condenser comprises a unit shell, and the two opposite sidewalls of the unit shell are provided with two air inlets respectively. A filler-coil pipe composite evaporation-type cooling unit is arranged in the unit shell, the top wall, corresponding to the unitshell, of the upper portion of the filler-coil pipe composite evaporation-type cooling unit is provided with an air discharging port, and the left and right sides of the filler-coil pipe composite evaporation-type cooling unit are provided with two dew point indirect evaporation cooling segments respectively. A water tank is further arranged in the unit shell, located below the two dew point indirect evaporation cooling segments and the filler-coil pipe composite evaporation-type cooling unit and connected with the filler-coil pipe composite evaporation-type cooling unit and the two dew pointindirect evaporation cooling segments through a water pipe network. The evaporation-type condenser solves the problem that since the temperature of circulation water is increased, the heat exchange efficiency of the evaporation-type condenser is lowered.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment, and in particular relates to an evaporative condenser based on dew point indirect evaporative cooling and precooling. Background technique [0002] The evaporative condenser combines the cooling tower and the condenser, and uses air and water as the cooling medium. Compared with the traditional water-cooled chiller, it saves the cooling water circulation system. However, during the actual operation of the evaporative condenser, the increase in the temperature of the circulating water will lead to a decrease in the heat transfer efficiency of the condenser. [0003] Dew point indirect evaporative cooling technology Compared with the traditional tube and plate tube indirect evaporative cooling technology, the indirect evaporative cooling technology has a large driving potential, which can make the temperature of the treated air break through the wet bulb temperature and approach ...
