Feasibility study of using heat recovery devices in HVAC systems in a building in the tropics
For non-domestic buildings, the electricity consumption mostly comes from the usage of the air-conditioning system. Therefore, energy savings must be achieved to save cost, and hence there is a need to apply heat recovery technologies such as run-around coils, plate-to-plate heat exchangers, heat...

description |
For non-domestic buildings, the electricity consumption mostly comes from the usage of the
air-conditioning system. Therefore, energy savings must be achieved to save cost, and hence
there is a need to apply heat recovery technologies such as run-around coils, plate-to-plate
heat exchangers, heat pipe heat exchangers and heat recovery wheels into the air conditioning
and mechanical ventilation (ACMV) systems for these buildings. The examples of nondomestics
buildings such as factories, hospitals and office buildings use more energy to
supply fresh air into the space in comparison to residential buildings. According to Yau
(2010), the changing of air must be at least 15 times hourly, and in certain cases such as the
hospital, the prohibition of recirculation of the return air in operating theatres to ensure the air
is clean from any virus or bacteria from the outdoor air is needed. The feasibility study on
using heat recovery devices in a new medium-size building in University of Malaya was
conducted. The potential of energy savings in the building was examined by studying the
performance of the air-conditioning system. The heat recovery systems were analyzed, and
the focus was on the energy savings of the HVAC system. The calculation of energy savings
and payback periods were analyzed for the chosen heat recovery devices installed in the
building. Based on the results obtained in this practical study, it is strongly recommended that
heat recovery systems to be installed to reduce energy usages of air-conditioning systems
operating in large buildings in the tropics |
