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 and 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 inlet and outlet ports for circulating coolant fluid through the tubing lengths to cool the phase change fluid in the cooling tower, and a plurality of the serpentine tubing lengths vertically aligned and 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.

Cooling coil for a thermal storage tower

An apparatus and method for cooling, air which apparatus includes an indirect evaporative cooler, an indirect contact chiller, a reheat coil component, an ice-thermal-storage component and an ice-manufacturing refrigeration chiller to provide alternative air-flow paths and alternative component combinations. Alternative fluid-flow paths are provided through electable combinations of the several components to effect the desired lowering of air temperature, relative humidity and air density in the cooled air.

Indirect contact chiller air-precooler method and apparatus

An apparatus and method for cooling, air which apparatus includes an indirect evaporative cooler, a direct-contact ice-water chiller, a reheat coil component, an ice-thermal-storage component and an ice-manufacturing refrigeration chiller to provide alternative air-flow paths and alternative component combinations. The method provides alternative fluid-flow paths through electable combinations of the several components to effect the desired lowering of air temperature, relative humidity and air density in the cooled air.

Air pre-cooler method and apparatus

The present invention describes a method of controlling the head pressure in a refrigeration or air conditioning system in order to maintain the internal discharge pressure and discharge line pressure substantially equal. The method consists of the steps of measuring the suction pressure of the working fluid, calculating the internal discharge pressure of the working lfuid by multiplying the suction pressure by the internal pressure ratio of the compressor, measuring the discharge line pressure of the working fluid and then comparing the internal discharge pressure to the discharge line pressure. If the difference between the internal discharge pressure and discharge line pressure is greater than some allowable tolerance, the capacity of the condenser is adjusted to equalize these two pressures.
