Summary
Heat recovery in rooftop units can generate significant energy savings, leading to an improvement in the overall performance of the system. These systems are mainly based on heat recovery from the exhaust air and incorporate other elements to utilize its energy. In this paper, we model with Modelica and IMST-ART several recovery systems to simulate their operation integrated in a rooftop unit with a reversible heat pump operating in both cooling and heating mode. With the generated model, we are able to analyze how the system operates. We compare the performance of the rooftop unit with each of the modeled heat recovery systems with the Seasonal Energy Efficiency Ratio (SEER) and the Seasonal Coefficient of Performance (SCOP) calculated according to the standard EN 14825. In conclusion, the heat recovery system that presents the best performance is a combination of a rotary wheel heat exchanger together with thermodynamic heat recovery.
