ACs are the only option for keeping homes cool during the hot and humid summers, but ACs always come with hefty electricity bills, outdoor compressor/condenser repairs, and the hassle of finding a mechanic. A cooling technology called CCS, or Centralized Cooling System, has solved all these problems. This technology isn’t just limited to paper; it’s already being used in modern green townships like Tengah, Singapore.
The specialty of centralized cooling systems is that they cool homes using water. Industrial chillers are installed on rooftops, delivering ultra-cold water to homes to cool them. With this approach, the hassle of paying AC bills, regular maintenance, and the noise of the compressor or condenser are eliminated.
If you have an AC installed in your home, you likely know that it comes with an outdoor unit, which must be installed outside the house. This exhausts the warm air from the room. Centralized cooling systems (CCS) don’t require such an outdoor unit.
This technology utilizes a network of power-efficient industrial chillers on building rooftops.
These chillers cool water to a very high temperature, and then this cooled water is delivered directly to homes through special pipes.
This system operates centrally on the rooftops and can cover multiple homes.
The cooled water then cools the air in the indoor units, cooling the home. There’s no need for noise, heat from the outdoor unit, or excessive electricity costs.
This system has undergone several improvements over time. For example, CCS indoor air-conditioning units initially faced problems with water leakage and condensation.
To address these issues, the system’s testing and commissioning team has been technically strengthened. Subsequently, the system is thoroughly inspected in homes before installation. Consequently, the number of CCS faults has been reduced to almost zero.
Due to these efforts, centralized cooling systems are rapidly replacing traditional air conditioners in Tengah. According to a survey, approximately 70% of respondents recommended the system to others.
