Title: (EN) USING HEAT RECOVERED FROM HEAT SOURCE TO OBTAIN HIGH TEMPERATURE HOT WATER
Abstract: front page image
(EN)

Heat is recovered from a heat source to heat water to high temperatures. Apparatuses, systems and methods are described to heat water to a high temperature by using heat, such as may be considered in some instances as waste heat, recovered from a heat source. The methods, systems, and apparatuses described utilize low pressure refrigerant(s) as a fluid to provide a refrigeration cycle that utilizes a source of heat to heat water to a high temperature. The refrigeration cycle can be with or without a cascade cycle. The refrigerant cycle in some examples uses an oil free compressor.
