摘要

Climatic conditions are not comfortable for human habitats in most of the Earth's land area. The increasing population requires the colonization of adverse locations, which increases the cost of heating and airconditioning. Modern life support systems have reached the ceiling of the use of traditional energy resources, as well as exceeded limits of greenhouse and other harmful gas emissions into the atmosphere.
This article describes one of the concepts of combined solar heating and air-conditioning system based on ejector technologies. The proposed system possesses a vast number of improvements towards the other types of climate control systems. Combined with the Maisotsenko cycle heat and mass recuperation process, the system's efficiency is increased by 3-10 times compared to all known thermally-driven cooling and heating solutions. Due to the absence of moving parts, the durability of the system is 3-5 times higher than of the available climatic systems. At least two times lower is the installed cost of the ejector-based climate control system compared to the combined cost of cooling and heating units. The appearance of an efficient and reliable thermopump along with the binary fluids related improvement of performance, allowed the ejector technology to become competitive with sorption type climatic systems. Application of new solar heat-driven thermotransformers allows to reduce energy consumption in housing and utility sector by 2-3 times and reduce greenhouse gas emissions up to 5 times.
