Combination of electric air heater and refrigeration system to reduce energy consumption: A simulation of thermodynamic system

This study is about the analysis of thermodynamic system of a refrigeration system with two condensers coupled in series to the electric air heater system. The condenser produces waste heat reaches 90°C and the heat is accumulated into a space heater up to 140°C. That means: the heater works only up to 50°C, so the temperature of the air is high and dry, but has a very low RCES (Ratio of Specific Energy Consumption) in dew point 20°C, which is indicate that the system is very significant.
