Air conditioning device with function of producing cold air by aid of waste heat and salt solution by means of indirect evaporative cooling

Abstract

The invention relates to the field of air conditioning technologies, in particular to an air conditioning device with a function of producing cold air by the aid of waste heat and salt solution by means of indirect evaporative cooling. The air conditioning device comprises solution dehumidifying units, solution regenerating units and an indirect evaporative cooling device. The solution is cooled and dehumidified by the solution dehumidifying units by the aid of external cooling water; the solution is heated and regenerated by the solution regenerating units by the aid of external industrial hot-water; high concentration of the salt solution of the dehumidifying units is kept by the aid of a solution circulating pipeline between a core of each dehumidifying unit and a core of the corresponding regenerating unit, and fresh air sequentially flows through the solution dehumidifying units and the two-stage indirect evaporative cooling device and is delivered into indoor environments via the dehumidifying and two-stage indirect evaporation. The air conditioning device has the advantages that the current surplus industrial waste heat is utilized, and accordingly the problem of incapability of effectively utilizing industrial waste heat can be solved; the fresh air can be produced and dried in non-dry regions by the aid of solution dehumidifying technologies, and obvious energy conservation effects can be realized.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning device which utilizes waste heat combined with indirect evaporative cooling of salt solution to prepare cold air. Background technique [0002] Energy saving and emission reduction, building a resource-saving society has become a very important task at present. Since the energy consumption of the central air-conditioning system has accounted for 40% to 60% of the total energy consumption of the building, reducing the energy consumption of the central air-conditioning system has become an important direction for the whole society to save energy and reduce emissions. While the air conditioning load is heavy, there is a large amount of industrial waste heat that cannot be used in summer. This is a big contradiction. The huge mismatch of energy utilization causes huge energy waste. The method of evaporative cooling is a method of utilizing natural cold s...
