METHOD AND SYSTEM FOR CONTROLLING A FLOW OF FLUID IN A MIXING LOOP

Preferred embodiments of the invention relate to a method of controlling a flow of fluid in a mixing loop of a system of mixing loops comprising a number of mixing loops each comprising a thermal load and each being fluidicly connected in parallel to a fluid source, in each mixing loop pressurization of said fluid is provided at least partly by a pump being a variable speed pump, and a bypass of said flow of fluid is recirculated in the mixing loop by a 3-way valve comprising a first inlet port fluidicly connected to said fluid source to receive a supply of fluid, a second inlet port fluidicly connected to receive said bypass and an outlet port fluidicly connected to an inlet side of said pump. Preferred embodiments of the invention also relates to a system of mixing loops.
