Heat source control system Ene-Conductor Improvement of system COP by optimal control which gets the best performance out of centrifugal chiller Various energy-saving control functions Remote monitoring ~optimization from individual equipment to whole system Being required for contemporary office buildings, large shopping malls or factories, it is an environmental protection effort and saving energy but the key issue is the heat source system. Energy-saving had to introduce high efficiency equipment some years ago. However it has to consider energy saving on heat source system levels rather than individual equipment. Estimation example - Improvement in COP of centrifugal chiller - Chilled water variable flow control - Cooling water variable flow control Electric power consumption in whole system 65% DOWN 1,200 Easy to use for an automatic optimization of the whole system Cooling tower Cooling water pump Chilled water pump Centrifugal chiller 1,000 65% 800 DOWN System COP Previous INV INV centrifugal chiller centrifugal chiller centrifugal chiller + EC series 3 System COP Significant Energy Reduction by total control of heat system Electric power consumption [MWh/year] 2 0 Estimation condition : chiller RT x 2units,Building air conditioner use * Auxiliary equipment : controlled by inverter 06

10 Experience More than 50 years of experience in air-conditioning and DHC system are reflected to improve performance and reliability of products. MARINA BAY NEW DOWNTOWN KUALA LUMPUR CITY CENTER The first district cooling plant in Marina South New Downtown, Singapore, located in One Ruffles Quay ORQ development, has been in operation since May This plant has high-efficiency chillers with thermal storage systems. Supplies will be extended to the integrated resort, Marina Bay Financial Centre and other new commercial buildings in the Marina Bay area as they are completed over the next few years. The two plants will be interconnected via a chilled water network in the new downtown. Kuala Lumpur City Centre KLCC area, a prime landmark in Kuala Lumpur, Malaysia s capital city is Kuala Lumpur s main business district, perhaps best known for the PETRONAS Twin Towers: the 452-meter high, 88-storey skyscrapers completed in1997. The area is also home to the Suria KLCC shopping complex, the Aquaria KLCC oceanarium, a park and a philharmonic hall, and as a result it is always crowded with both business persons and visitors. We have received an order for 13 large-size centrifugal chillers, with a total cooling capacity of 36, RT.Delivery of the chillers is slated for completion in September RT Centrifugal chiller 1 units 2,844 RT Centrifugal chiller 11 units 2,000 RT Centrifugal chiller 2 units 3,697 RT Centrifugal chiller 2 units Singapore AMARI WATERGATE BANGKOK Amari Watergate Bangkok is a luxury 5 star hotel located in centre of Bangkok.
