Abstract

The present invention belongs to an improvement of an evaporative cooling cool supply device with dry air energy as power source, and in particular relates to an evaporative refrigeration water chilling unit. A spraying water distributor and a blower are arranged above a direct evaporative cooling heat exchanger; a water storage pool with a circulating water pump is arranged inside a casing on the lower part of the direct evaporative cooling heat exchanger; an air inlet of the casing is provided with a surface air cooler; a water inlet of the circulating water pump is connected with a water outlet at the bottom of the water storage pool through pipelines; a water outlet of the circulating water pump is connected with an indoor sensible heat cool supply terminal through pipelines; an outlet of the indoor sensible heat cool supply terminal is connected with the surface air cooler through pipelines; a water outlet of the surface air cooler is connected with a spraying water distributor through pipelines. The present invention can realize the effective utilization of the cold energy of cold water, reduces the irreversible loss of heat-moisture exchange, improves heat-moisture exchange efficiency, ensures that outlet water temperature can approach to the dew point temperature of inlet air, and improves the efficiency of utilizing dry air energy.

Description

technical field [0001] The invention relates to the technical field of renewable energy, and belongs to the evaporative cooling and cooling technology using dry air energy as a power source, in particular to an evaporative cooling chiller. Background technique [0002] Dry air energy refers to the amount of energy (cold) that unsaturated air has when it tends to be saturated. It is expressed as the difference between the enthalpy value corresponding to the dry bulb temperature of dry air and the enthalpy value corresponding to the dew point temperature of dry air. Dry air and water The cold energy obtained by heat and moisture exchange is a green and clean renewable energy. Dry and hot regions contain abundant dry air energy. Rational use of dry air energy for air conditioning and refrigeration to replace conventional energy has important practical significance for sustainable development. [0003] In the prior art of evaporative cooling air conditioners, evaporative coolin...
