hi,
we have a primary chilled water system, with a constant flow pump.
the head required is 27.5metres and 750 gallons.
but presently the pump delivers a flow of 900 gallons and 25metres head. chiller is of 300 tonne capacity.
so now i want to reduce the pump speed by installing a variable frequency drive. if i reduce the flow to 750 gallons the head will be reduced toaround 18 metres.
what i wouldlike to know is whether at this reduced head the water will be reaching all the places and will the variation in flow will affect the indoor room temperatures and to what extent.
help me.
