4 Energy savings
Comprehensive building simulations have been examined for energy consumption,
comfort, and control accuracy. The Economizer tx2 algorithm generates the corner
values to compare energy consumption to a conventional air conditioning plant
control with ERC control included in the temperature sequence.
Building:
Museum
Primary plant:
Heating: Gas burner,
centralized ventilation plant with heating coils
Cooling and dehumidification: Refrigeration machine,
centralized ventilation plant with cooling coils
for humidification and dehumidification
Humidification: Central ventilation plant with steam humidifier
ERC control: ERC is integrated in the temperature sequence
with comfort band
Result:
Simulation results show that the Economizer tx2 application results in typical
energy savings of 5 to 10% annually. Savings of up to 40% are possible depending
on room use and outside air conditions.
