Foster Shanghai Co. covers an building area of 11123m2 including
main building, 5727m2 and accessory building, 5395m2 with the height
of 26.4m. The building requires comfort air conditioning and fresh
air in summer and winter. The project summaries the principles and
features of air-cooled heat pump, water-cooled heat pump and ground
source heat pump and estimates the air conditioning costs of these
three schemes. Based on this, we compare the economic values and
auxiliary heat source of these scheme, analyses the operation
economic value of hot water system and calculate the air
conditioning load. The study shows that the water-source heat pump
is the most economical scheme and natural gas boiler is recommended
as the auxiliary heat source of the air conditioning heating
process. The study also works out how much energy to be saved by
using solar central heating technique, calculates the first cost
payback period and provides the proposal of using natural gas boiler
system as hot water supply scheme.
