Bhai one question please.. what is the source of building water loop? From where it comes? If it is return from ahu,fcu then first there should be supply yes. Please explain
Absolutely bro, there is supply. which is going into the building from the CH water pump discharge line. First the same water will come through our equipment like AHU, FCU, in the heat exchanger. Then the temperature of the water in the heat exchanger will drop and it will flow from the outlet of the heat exchanger into the CH water pump. It will go in building again by the pumps and the cycle will continue.
@@Engineering_MEP bro i am a little confused…the supply going to the building from CH water pump discharge - Where is that water coming from? Because in district cooling, the water from empower enters the building heat exchanger absorbs heat and goes back to empower without entering the building yes. So the cold water that goes to the building - where is that water coming from? Kindly reply thanks a lot.
Hi! Thanks for your question. The temperatures in district cooling systems can vary slightly based on the specific design and operational conditions, but here are the typical ranges: District Cooling Water Supply Line Temperature: Usually between 4°C to 6°C (around 39°F to 43°F). District Cooling Water Return Line Temperature: Typically between 12°C to 14°C (around 54°F to 57°F). Building CHW Supply Line Temperature: Generally between 6°C to 8°C (around 43°F to 46°F). Building CHW Return Line Temperature: Typically between 12°C to 14°C (around 54°F to 57°F).
Hi anyone please advise, the district cooling estimated load for 1 building( ie: an apartment building required 1000TR (3500kW)= DC Plant load of 3500/5(cop)=700kW). This 700kW is the total energy consumption including the ETS and DCP load ? Or do we need to add a separate power consumption for the both ETS and DC plant’s mechanical load??? If someone have the actual energy consumption rule of thumb, please comment…
Hi, great question! The 700 kW you calculated (based on the COP of 5 for a 1000 TR load) represents the total energy consumption required to deliver 1000 TR of cooling, assuming that this value already accounts for the efficiency of the District Cooling Plant (DCP). However, this 700 kW typically covers the energy used by the chillers in the DCP but does not include the additional energy consumption for the Energy Transfer Station (ETS) or other auxiliary mechanical loads (like pumps, fans, or controls) that are part of the system. In a typical district cooling setup: ETS Energy Consumption: The ETS, located in the building, usually consumes additional power for circulating chilled water (CHW) within the building, control systems, and sometimes secondary pumps. DCP Mechanical Load: The DCP itself also has mechanical loads like cooling towers, pumps, and fans, which are not always included in the chiller energy calculation. Therefore, you would need to account for these separate power consumptions when calculating the total energy requirements for the building and the district cooling system. If you’re looking for a rule of thumb for the additional loads, it varies by system design, but a common estimate is an additional 10-20% on top of the chiller power consumption to account for auxiliary systems (ETS, distribution pumps, etc.). However, for an accurate calculation, a detailed analysis of the specific system design is recommended. Thanks.
Sir kindly let me know about the temperatures District cooling water supply line temp? District cooling water return line temperature? Building CHW supply line temp ? Building CHW Return line temp?
