Hi guys, i have very well insulated residential building where district cooling system and fan coil units are used for air conditioning. Due to high performance of the heat insulation used, the cooling load calculated were very low. when i came to selecting the fan coil unit in each room, i had to choose ones of capacities that are higher than the cooling load of the room by around 50%. The heat exchangers and water pumps are sized based on the calculated cooling load. Now, the problem is that the chilled water flow of the system is 50% less than the chilled water flow required by sum of all fan coil units. i know fan coil units wouldn't work all together but I'm still concerned about some issues that may arise due to this big difference between calculated loads and selected fan coil unit capacities. Please note that I'm using variable speed pump with two way valve for each fan coil.
is there any problem with such system, your advise is highly appreciated
