Passive evaporative cooling and ventilation cooling system combined with building

Abstract

The invention discloses a passive evaporative cooling and ventilation cooling system combined with a building. The system comprises multiple downward ventilation type evaporative cooling towers located in the building. Each downward ventilation type evaporative cooling tower is vertically arranged, and the top of each downward ventilation type evaporative cooling tower penetrates out of a roof ofthe building. An air inlet is arranged on the segment, penetrating out of the roof of the building, of each downward ventilation type evaporative cooling tower by a circle. A spraying device and a direct evaporative cooler are sequentially arranged on each downward ventilation type evaporative cooling tower located in the building from top to bottom. An air supply opening is formed in the wall, corresponding to the corresponding direct evaporative cooler, of each downward ventilation type evaporative cooling tower. According to the passive evaporative cooling and ventilation cooling system, the passive ventilation cooling technology and the evaporative cooling technology are combined with the building, indoor ventilation can be enhanced, and meanwhile the processes of cooling, humidification and purification can be effectively achieved on air; the indoor temperature is adjusted to a proper temperature through low energy consumption, and environment protection is achieved; and the manufacturing cost and the operating cost are low, and natural energy is reasonably utilized.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a passive evaporative cooling ventilation cooling system combined with buildings. Background technique [0002] According to the current energy consumption status and national policies, the passive energy-saving natural ventilation cooling mode of using renewable energy combined with climate characteristics has attracted widespread attention of researchers. Traditional passive downdraft cooling technology (PDC), under natural conditions, after the wind enters the ventilation tower or patio, because the density of hot air is lower than that of cold air, the cold air will naturally sink, thus entering various functional spaces in the room, and finally discharged outside after being heated. , so as to achieve the purpose of ventilation and cooling; while the evaporative cooling technology uses the temperature difference between dry and wet bulbs of the...
