First and second law of thermodynamics have been used to analyze the performance of an experimental heat transformer used for water purification. The pure water is produced in the auxiliary condenser delivering an amount of heat, which is recycled into the heat transformer increasing the heat...

A system of energy recovery depends on the process operation conditions from which it receives the energy when a Carrol–Water pair is used. To improve the performance of the energy recovery system, the variables of temperature, pressure and concentration must be in balance. External sensors...

A preliminary feasibility study of the implementation of various absorption heat pump configurations in a Kraft pulping process has been performed. Three different cases were considered: (i) integration of a double lift heat transformer into the heat recovery circuit of the wood chips digesters...

The subject hereof are two typical examples of waste heat and low-temperature heat use and the objective is to evaluate economic effectiveness taking into account various boundary conditions. The first facility considered is an “earth-coupled” heat pump with direct evaporation used as a...
