The purpose of this study is to compare the energy performance of a convergence high-efficiency HVAC module developed for application to residential buildings. The developed HVAC module is a system that combines a heat pump and an energy recovery ventilation system (ERV). The developed system is designed to recover energy using the ERV and heat-exchanged air passing through the heat exchanger of the heat pump. The study was conducted in a demonstration-house test building located at the LHI Housing Performance Research and Development Center. General equipment (cooling, heating, ventilation) was installed based on the common area of the demonstration house and compared with the condition of maintaining the same indoor temperature and humidity relative to the outdoor temperature in winter. The test results showed that, compared to the general equipment, the convergence HVAC module consumed less power, while maintaining a comfortable indoor environment. It consumed approximately 33% less electricity compared to the general equipment.
