Solar Air Collectors: How Much Can You Save

A collector efficiency curve is used to determine the output of solar air collectors based on the testing of seven solar collectors sold in Iowa. In this application the solar heater is being used as a space heater for a house. The performance of the solar air heater was analyzed and an 8% savings in energy was achieved over a one year period using two 4'' x 8'' collectors in a typical house.

Solar system installation at Louisville, Kentucky (final report)

A contract was awarded in June 1976 for the installation of a solar space heating and domestic hot water system at 2400 Watteroon Trail, Louisville, Kentucky. The overall philosophy used was to install both a liquid and a hot air system retrofitted to the existing office and combined warehouse building. The 1080 sq ft office space is heated first and excess heat is dumped into the warehouse. The two systems offered a unique opportunity to measure the performance and compare results of both air … more

Double absorber plate. Final technical report, October 1, 1977-November 15, 1978

An air collector is described that avoids the high air side pressure drops and the use of inlet and outlet header ducts to connect collectors in parallel. The precontract collector design is shown. The major novelty of the collector rests in having two absorber plates which heat a relatively broad air passage. The current collector utilizes a 4 mil fiberglass reinforced plastic sheet (Kalwall) outer glazing, a 1 mil fluorocarbon (Teflon) inner anticonvection layer/inner glazing, a partially bla… more

Economic performance of passive solar heating: a preliminary analysis

As the interest in solar energy applications for residential space heating grows, it becomes imperative to evaluate the economic performance of alternative designs. For the thermal storage wall two types of storage medium--masonry (Trombe) and water are examined. In addition a night insulation option is included in the thermal storage wall concept, thus giving rise to four alternative passive designs. The economic performance of these alternative designs are evaluated on a state-by-state basis.… more

Trombe wall vs direct gain: a comparative analysis of passive solar heating systems

Until recently only the thermal storage wall passive solar heating system had been characterized by thermal network calculators using hour-by-hour historical weather data. The greater popularity and market acceptability of direct gain systems has led to a lively, but inconclusive debate concerning the relative effectiveness of the two configurations. The recent development and validation of PASOLE/SUNSPOT, a thermal network code for direct gain enclosures, has provided the tool necessary for a … more
