Abstract

Application energy-efficient for air conditioning equipment are the main indicators of the energy conservation and sustainability in Heating, Ventilating, and Air Conditioning (HVAC) systems. The heat recovery is one of the methods of energy savings and optimization. The present work aims to compare the pump energy between two controlling methods (continuous mode and intermittent mode) for flowing the water from the heat recovery to the thermal storage tank. The continuous and intermittent flow was applied by on/off cycles controlled by the electrical system at 40-degree Celsius. This preliminary study focusses on total power consumed by the heat recovery pump, and total heat absorbed by the water in the heat recovery unit. For the two-flowing mode of heat recovery pump, the working parameters were charted and analysed by comparing pump energy data. The result shows that the energy consumption decreased by 58 percent and the total heat absorb was decrease by about 8 percent for intermittent flow condition.
