Evaporative cooling chiller with rotating water distribution

Abstract

The invention discloses an evaporative cooling type water chilling unit adopting rotary water distribution. The evaporative cooling type water chilling unit adopting rotary water distribution comprises a unit shell. An air inlet is formed in one side wall of the unit shell. A vertical tube type indirect evaporative cooler and a pure-reverse-flow type direct evaporative cooler are arranged in the unit shell in sequence according to the flowing directions of the air entering the unit. Air outlets are formed in the portions, located above and corresponding to the vertical tube type indirect evaporative cooler and the pure-reverse-flow type direct evaporative cooler, of the top wall of the unit shell respectively. The pure-reverse-flow type direct evaporative cooler is externally connected with a plate heat exchanger. A closed loop is formed by the plate heat exchanger and the tail end of an air conditioner. The evaporative cooling type water chilling unit adopting rotary water distribution has the advantages that the occupied area is small, the efficiency is high and energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and relates to an evaporative cooling water chiller using rotating water distribution, in particular to a tubular indirect evaporative cooler, a pure countercurrent direct evaporative cooler, a rotating water distributor and a plate heat exchanger Composed of evaporative cooling chillers. Background technique [0002] Evaporative cooling technology, as an efficient, environmentally friendly, water-saving and energy-saving cooling technology, relies on the latent heat of vaporization when the cooling medium evaporates to take away the heat of the main equipment to achieve the effect of cooling. Relying on the latent heat of vaporization, the evaporative cooling equipment can reduce the temperature of the unit's own circulating water to a sub-humid bulb temperature lower than the wet bulb temperature of the outdoor air, and can provide high-temperature cold water for users or air...

AI Technical Summary

Problems solved by technology

At present, the maximum limit of the cold water temperature produced by general chillers and cooling towers is to reach the wet bulb temperature of the outdoor air, while the cold water produced by evaporative cooling chillers can be lower than the wet bulb temperature of the air, and the efficiency can reach 100%. , but the existing evaporative cooling chillers have the disadvantages of large footprint, low efficiency and high energy consumption
