Embodiment Construction

[0026] A kind of progressive indirect evaporative cooler, embodiment 1 shown in Fig. An induced draft fan 4 is installed on the tuyere, an exhaust fan 3 is installed on the outlet of the secondary air, an indirect evaporative cooler is installed in the casing 1, a water distributor 2 is arranged above the indirect evaporative cooler, and a water distributor 2 is installed below it. A water tank 6 is provided to supply water to the water distributor 2 through a water pump 5. The indirect evaporative cooler is a horizontal plate-type indirect evaporative cooler 7, and its dry channel is a horizontal channel. The horizontal projection of the plate-type indirect evaporative cooler 7 is a right-angled trapezoid. The secondary air supply surface of the plate-type indirect evaporative cooler 7 is an inclined surface, and the dry passages on the inclined surface are elongated from near to far, so that the once-humid cooling The air flow is divided into primary air and secondary air. ...

Abstract

The invention relates to the technical field of renewable energy, which belongs to an improved water evaporation refrigeration air conditioner, in particular to a progressive indirect evaporative cooler, which comprises a water distributor arranged above the indirect evaporative cooler; a water tank is arranged below the indirect evaporative cooler, wherein, the water tank supplies water to the water distributor via a water pump; the indirect evaporative cooler is provided with a secondary air blowing surface, which is a slanted surface; dry channels are arranged on the slanted surface, and extend forwards to divide sensible cooling primary air flow into primary air and secondary air, wherein, the primary air flows in the through dry channels, and the primary air exhausted from the vents of each phase of the dry channel on the slanted surface is used as the secondary air, which flows into corresponding wet channels. The invention improves the heat transfer efficiency through using less amount of secondary exhaust to obtain lower exhaust temperature of the final primary air after sensible cooling.

Description

technical field [0001] The invention relates to the technical field of renewable energy, and belongs to the improvement of a water evaporative refrigeration air conditioner, in particular to a progressive indirect evaporative cooler. Background technique [0002] Evaporative cooling technology is an air-conditioning method that utilizes the abundant dry air energy contained in the air in dry and hot areas for cooling. Since it does not use fluorine-containing refrigerants, it adopts fresh air regulation, energy saving and environmental protection, good indoor air quality, and simple structure. It has been widely valued and promoted at home and abroad, and has achieved good results. [0003] In regions with dry and hot climate conditions, promoting the use of dry air energy and other new energy sources for air conditioning and refrigeration to replace conventional energy sources has important practical significance for the sustainable development of the economy and society. ...
