Solar domestic hot water system manual for Day's Inn, Garland, Texas
The solar domestic hot water system installed at Day's Inn, I-30 and 6222 Beltline, Garland, Texas is described. The system is a solar collector array used to provide from 39.9% in December, to 84.7% in August, of the domestic hot water usage of the Day's Inn in Garland, Texas. The system is an automatic draindown design employing an atmospheric vented storage tank for storing the hot water collected by the 998 sq. ft. collector array. The system's major components and features are: 44 Daystar 1400 collectors, gross square footage of 998 sq. ft.; 1000 gallon vented storage tank; 3 B and G pumps: one for the collection loop, one for transfer of energy from the thermal storage tank to the shell side of the B and G heat exchanger; the third to circulate water from the three existing DHW tanks through the tube side of the heat exchanger; 3 one-inch Taco automatic valves to control the heating of water through existing DHW tanks; vacuum breakers to ensure draindown when main circulator pump stops running; pressure gauges installed across each pump so that system flow rates can be set and read periodically as a preventive maintenance check; collector angle of 30/sup 0/.
