Photovoltaic coil-dew point indirect and direct evaporative cooling compound water chilling unit

Abstract

The invention discloses a photovoltaic coil-dew point indirect and direct evaporative cooling compound water chilling unit. The water chilling unit comprises a unit shell. An air inlet b is formed in one side face of the unit shell. An inner cooling type coil indirect evaporative cooler, a cross flow coil-dew point indirect evaporative cooler and a packing tower type evaporative cooling water chilling device are sequentially arranged in the unit shell in the air flowing direction. An exhaust port a is formed in the corresponding position, above the inner cooling type coil indirect evaporative cooler, of the top wall of the unit shell; an exhaust port b is formed in the corresponding position, above the packing tower type evaporative cooling water chilling device, of the top wall of the unit shell; the water chilling unit further comprises a photovoltaic solar power supply system arranged on the top wall of the unit shell; and the photovoltaic solar power supply system is connected with the inner cooling type coil indirect evaporative cooler, the cross flow coil-dew point indirect evaporative cooler and the packing tower type evaporative cooling water chilling device. Through the photovoltaic coil-dew point indirect and direct evaporative cooling compound water chilling unit, photovoltaic drive can be achieved for assisting while the water outlet temperature of the evaporative cooling water chilling unit can be lowered.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment, and in particular relates to a photovoltaic coil-dew point indirect and direct evaporative cooling composite chiller. Background technique [0002] Evaporative cooling air-conditioning technology uses water as the cooling medium, and uses renewable energy "dry air energy" to absorb heat and cool through water evaporation. Because air and water are in direct or indirect contact, clean cold air or high-temperature cold water can be produced. [0003] Although the dry area has a large temperature difference between the dry and wet bulbs, it has the natural advantage of abundant "dry air energy". However, it is difficult for the existing evaporative cooling chillers to produce cold water at a lower temperature, and the size is large, and the practical application is also subject to some restrictions. The unit structure needs to be optimized and improved, and the performance needs t...
