An indirect-direct evaporative air conditioner based on annular water distribution

Abstract

An indirect-direct evaporative air conditioner based on annular water distribution disclosed by the present invention includes a casing, an air inlet is opened on the top of the casing, and a standpipe indirect evaporative cooler and a direct evaporative cooler are sequentially arranged in the casing from top to bottom. Cooler, the side wall of the shell corresponding to the direct evaporative cooler is provided with an air outlet; the standpipe indirect evaporative cooler includes a primary filter, a water distributor a, and a packing a arranged in sequence from top to bottom , vertical heat exchange tube group and water collection tank a, the water collection tank a communicates with the water distributor a through the circulating water pipe a, the water distributor a includes several annular water distribution pipes a of different diameters distributed sequentially from the inside to the outside, each A plurality of evenly distributed nozzles a are installed on each of the annular water distribution pipes a, and the plurality of annular water distribution pipes a are all connected to the circulating water pipe a, and the filler a is a cylindrical filler. The air conditioner adopts a circular water distribution method, which makes the water distribution of the entire air conditioner filling more uniform and reduces dry spots.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to an indirect-direct evaporative air conditioner based on annular water distribution. Background technique [0002] In today's increasingly harsh environment, the use of renewable energy has attracted more and more attention, so as to save the consumption of fossil energy and reduce environmental pollution. For example, solar energy, wind energy, water energy and geothermal energy are used. As an energy-saving and environmentally friendly evaporative cooling ventilation and air conditioner, more and more people love it. The widespread use of evaporative cooling equipment will further reduce energy consumption and protect the environment. However, existing air conditioners have the problem of dry spots on the filler due to uneven water distribution on the filler. Such air conditioners have low efficiency and waste energy, so some air...
