From refrigeration principle, above various technical scheme does not all break through single evaporation refrigeration or the limitation of desiccant cooling, thus their technical-economic index also difficulty have breakthrough improvement.
Air purifier: the today becoming the focus that people pay close attention in air pollution becomes the required household effects of average family very soon, but it can only eliminate the solid particle in room air, can also decomposing or formaldehyde adsorption of minority, the pernicious gases such as benzene, but its efficiency is very low, and must close the door when using, indoor carbon dioxide, the savings of carbon monoxide, the health of shortage to people of fresh oxygen brings new harm, with health care maximum magic weapon---ventilation runs in the opposite direction, saying nothing of the configuration of its family expenses is exactly unit even up to ten thousand of thousands of unit easily, ordinary consumer is allowed to hope and to halt.
In addition this three kind equipment is that Each performs its own functions, and a general human residential space needs three complete, both uneconomical, aobvious numerous and diverse again, even becomes the burden of family.
Consumer look forward to have a kind of there is indoor and outdoor ventilation simultaneously and reclaim ventilation energy and the new wind of purification refrigeration, compressor-free, non-freon the conditioner of the several functions such as refrigeration be born, but have not yet to see such technical scheme so far.
