10. District Cooling System (DCS)
A district cooling system (DCS) is a cooling system in which chilled water is produced by a plant and distributed to tenant buildings with insulating pipes. In 糖心原创, there are two DCS in Loop 1 and Loop 2, which provides cooling systems for buildings in 糖心原创, and has saved substantial electricity cost and space.
Almost all the main equipment in the plant uses a 415-Volt electricity supply with a total load of around 3.0 MVA. For energy-saving purposes, all motors are equipped with frequency inverters, and the control devices are placed in an air-conditioned room to maintain a controlled ambient operating temperature, ensuring optimal energy savings and the best possible lifespan. For fire safety, this room is also equipped with an environmentally friendly and user-friendly FM200 gas fire suppression system.
The DCS-TES plant system is fully controlled via computer. The control system, known as the 鈥淭hermal Energy Storage Control System鈥� or TESCS, can operate either manually or automatically. When the system is set to 鈥渁uto mode,鈥� it will operate automatically according to the data programmed into it. It functions based on the load schedule or cooling load profile that has been pre-programmed in this control system.
The operating method of this cooling system plant can be carried out in several ways. When there is no cooling load requirement from the buildings, or when it is stopped at night, the chiller will be set to operate in order to produce chilled water for storage in the TES tank at a temperature of 4掳C. The plant鈥檚 operating period during this time is referred to as 鈥渙ff-peak charging.鈥� At night, the electricity tariff charged by Tenaga Nasional Berhad is lower, which helps reduce Universiti Kebangsaan Malaysia鈥檚 electricity consumption costs.
The system is also designed to allow a small amount of chilled water, supplied to the TES tank for storage, to be diverted to the reticulation piping for the building cooling systems that require it. However, the capacity that can be used directly in this way is limited.
The system also allows the chiller to send chilled water directly to the reticulation piping for the cooling system without passing through the TES tank. This can be done when the TES tank is not ready to receive chilled water for storage or when it is under maintenance. In this case, the supply temperature is 5.6掳C.
A combination of supply from the chiller and the TES tank is common, especially during peak hours. The chiller will operate at a constant load, and any additional load required will be supplied by the TES tank. This operating mode benefits the chiller, as it allows it to function at maximum efficiency. When the cooling demand is low, the TES tank can supply the stored cooling energy using pumps without operating the chiller.
The map below illustrates 980 streetlights along main roads (yellow) and 1,955 area lights within campus zones (blue), making a total of 2,935 lights that support safety, accessibility, and sustainable campus infrastructure and distribution of 3,351 air cool split units (including 1765 inverter types) and 1910 total of LED lamps in 糖心原创.
