Saturday, August 18, 2007 CH’s innovative P20M aircon
CEBU City Mayor Tomas Osmeña wants to make sure the P20-million waste-to-energy air conditioning system will work at the renovated legislative building, as this will give the City the most advanced cooling technology.
The same system will be used at the South Road Properties (SRP) that is why the mayor wants to see working models abroad.
Osmeña is leaving on Monday for his trip to Thailand to check the models for transmission of chilled water, one of the components of the waste-to-energy air conditioning system.
The mayor will also go to India, where the air handling units and chillers are manufactured.
Saving energy
“I want to study this thing more concretely because this is going to be the model for the SRP. It will be a centralized cooling system where we will pump steam to produce cool air for the entire 300 hectares. This will give us the most advanced development in cooling system,” he told a news conference last Thursday.
Osmeña will be gone for four days and is expected to be back at City Hall on Aug. 27. Vice Mayor Michael Rama will be designated acting mayor.
The mayor wants to use the district cooling system, or a centralized cooling system for wide areas, at the SRP and the four-story legislative building to cut down on electricity consumption.
New system
Instead of using electricity for air conditioning units, the district cooling system will use biomass materials such as coconut shells and rice husks to produce steam, which will then heat lithium bromide to capture moisture.
Using chillers, the moisture will be converted to cool air that will circulate around the building.
Once the system is in place, Cebu City will be the first local government unit in the country to use a district cooling system.
During the City Council session last Wednesday, Councilor Nestor Archival reported that the installation of the pipes for the air-conditioning system is one of the things causing a delay in the renovation works at the legislative building.
The City’s engineers and consultants, though, assured the council that in two weeks’ time, there will already be significant developments in the renovation. (LCR)
