COOLING COIL FOR A THERMAL STORAGE TOWER

摘要

A cooling coil arrangement for a cylindrical tower provides coverage of a larger area of the cylindrical footprint of a cooling tower to enable more economical usage of the vertical tower storage capacity for ice thermal storage, which coil arrangement has a plurality of coils arranged in multiply arranged planes with serpentine layouts of each tubing length generally having a vee-shaped layout in each plane between the longitudinal axis of the tower a nd the tower housing, which tubing lengths are provided in each sector of each plane normal to the axis and having a tubing length therein, and the manifolds coupling the tubing lengths to inle t and outlet ports for circulating coolant fluid through the tubing lengths to cool the phase chang e fluid in the cooling tower, and a plurality of the serpentine tubing lengths vertically aligned a nd preferably arranged with the tubing section of one u-shaped segment of a first tubing length in vertical alignment with the gap of another of the tubing lengths which provides more uniform distribution of the cooling capacity of the cooling fluid and consequently a more uniform development of any crystalline formation of the phase-change fluid on or about each tubing length.
