Portable water purification system integrated to a heat transformer

Water is a natural resource essential for life and for most economic activities developed on earth. Population growth and lack of water in some regions of the world has led humans to design and implement new technologies to use water in an efficient way. Water quality requirements in the industrial sphere are higher everyday. Development of desalination technology through a water purification system integrated to heat pumps has taken more than two decades. Absorption heat pumps use low quality energy in a waste heat form and a small quantity of high quality energy. This characteristic has made possible using these systems in quite a few places. The following work presents the results of the experimental tests applied to a portable water purification system integrated to a heat transformer (TTAPPA), where the low quality waste heat is simulated and LiBrwater is used as a working solution.

Analyzing the results obtained with the TTAPPA, we can conclude that: • • • The heat transformer integrated to a water purification system works with waste heat temperatures from 68–78°C. The distilled water quality is similar to those obtained from a laboratory’s electrical distiller. The system is able to use other working mixtures in order to improve the COP values.
