Application of energy recovery ventilation (ERV) solutions to enhance energy efficiency in buildings

Abstract

The heating, ventilation, and air conditioning (HVAC) systems often account for the largest amount of energy consumption in buildings' total energy consumption. Ther efore, improving the energy efficiency of HVAC systems plays an important role in enhancing energy efficiency in buildings. Applying energy recovery ventilation (ERV) technology in HVAC systems is one of the potential solutions in reducing energy consumption of HVAC systems. The main objective of this study is to analyze and evaluate heat recovery technologies including (1) Rotary heat exchanger, (2) Fixed plate heat exchanger, (3) Heat pipe, and (4) Run around and their applications in HVAC systems. The research results can contribute in providing the scientific and practical basis in promoting the application of ERV technology to improve energy efficiency in buildings in Vietnam.

Key words: Heating; ventilation; and air conditioning (HVAC); energy efficiency; rotary heat exchanger; fixed plate heat  exchanger; heat pipe; run around.
