- Abstract
- During 1972 and 1973, the National Bureau of Standards conducted controlled laboratory tests on a factory-built four-bedroom house having a floor area of 110 sq m (1200 sq ft) equipped with a conventional gas furnace and central electric air conditioner incorporated into a forced air distribution system. During 1974, the house was moved onto the NBS grounds and a solar heating and cooling system was designed to be added to the house. Calculations were made to show that more than 75% of the yearly energy needs for heating, cooling, and supplying domestic hot water could be obtained from the sun. This report deals with the design and construction of the retrofitted system. It consists of 45 sq m (485 sq ft) of double-glazed, flat-plate solar collector, 5.7 cu m (1500 gallons) of water storage, and a 10,000 W (3 ton) lithium bromide absorption air cooling unit.
