Experiment Of Hydraulic Condition Of Floor Panel Heating Systems

As a new heating system of independent each house, the low temperature floor radiation heating system has been widely used at prasentA good deal of study on its comfortable and heat-saved has been getting in internal and external while little on hydraulic condition.Moreover,it has no general formula of resistance count due to using new plastics tube underground collecting-heat.Thus the paper mainly measures house water-volume and pressure-loss of "Fu Tai Ming Yuan"typical houses which lie in Dongli Ward of Harbin. Based on the experimental study on the equal spacing and two-pass system with PEX pipes, it also obtions the curves reflecting the relation between friction coefficient A and Re, finds fluid lie turbulence flow area ,and provides the calculation formula of the A . Though experimental study two-circuit,three-circuit and four-circuit,obtions the varying system of resistance number S .With using computer programs,the paper analysed the influence on water-volume inflowing heating tube.Furthemore,it finished counting max-pressure unequilibrium rate on same-progrem system and different one.
