Abstract

The invention discloses a method for heat humidity independent treatment of air by segmental utilization of condensation heat. In the novel method for the heat humidity independent treatment of the air, solar energy and the condensation heat of a refrigerating system are comprehensively utilized as a solution circulation driving heat source, condensation waste heat is segmentally utilized, and solar energy accumulation is combined with solution energy accumulation. The method comprises the following steps of: pre-heating a solution by a solar heat collector / energy accumulator, absorbing thecondensation heat by a shell and tube heat exchanger; and continuously heating by outdoor air which absorbs the remained condensation heat of a condenser to make a temperature rise in a solution regenerator. In summer, indoor air is dehumidified by a solution dehumidifier to make the temperature rise and then passes through an evaporator of the refrigerating system to make an evaporating temperature rise, so the refrigerating coefficients of the system are effectively improved. In winter, the outdoor air passes through the solution dehumidifier and then passes through the evaporator of a heatpump system, so the total heat of outdoor humid air is fully utilized as a low-temperature heat source of the evaporator of the refrigerating system, energy source utilization ratio is improved, and the frosting problem of an outdoor machine in winter is effectively solved.

Description

technical field [0001] The invention relates to a method for independently treating air with heat and humidity, specifically a method for independently treating air with heat and humidity, which utilizes condensation heat in stages and combines solar heat collection / energy storage and solution energy storage, and belongs to solar energy utilization, refrigeration and air conditioning technology field. Background technique [0002] With the rapid development of economy and society, my country's energy demand is growing rapidly. The shortage of energy and the resulting environmental pollution are becoming important constraints to the sustainable development of my country's economy and society.
