[Bldg-sim] district cooling

[韩星]

Dear Ben,
I think you are right, the DCLD is the most important issue when considering District Cooling. I think you could calculate the pump energy consumption compared to the chiller consumption to determine whether to use the district cooling or not.
I have a district cooling case in China. The ground surface area of the park is about 58000m2 (160000m2 building area), and the peak cooling load is 5000RT. Actually, the park is even larger. the peak load of the district cooling will be increased to 16000RT, but I don't have the information of the rest of the park surface area. For your reference.

Dear All,
It is stated in ASHRAE Handbook 2008 - HVAC Systems and Equipment – that one of the major factors for deciding on the applicability of district cooling is the design cooling load density DCLD (i.e., cooling load per unit area of the ground surface). I wonder if someone came up with a reference value of DCLD above which district cooling becomes feasible. I know that DCLD reference value will depend on many environmental and financial factors, However, I want to use the DCLD reference values that you will provide as verification indices for the DCLD reference value for Kuwait.
Many thanks in advance.
