In this paper,a set of horizontal coils were added to the primary vertical coils near the bottom of the tank to help to crack the cylindrical ice columns easier at the early stage of discharging.

This paper studies the fransfer heat and hydraulic character of several plane curved tube systems with low supply water temperature in arange of flow by experiment, and gives the telationship befween the transfer heat coefficient and resistance cofficient with Renolds number and geometry of fube This conclusion is useful in the engineering applicafion of floor heating.
