Design, Construction, and Testing of the Colorado State University Solar House I Heating and Cooling System. United States Special Format Report

Description: The primary objective of the project is the design, construction, testing, and evaluation of a practical system for utilizing solar energy to drive heating, cooling, and domestic hot water subsystems, supplemented as necessary with auxiliary fuel. System design was accomplished during the first five months (September 1973 to January 1974) and construction completed during the following five month period (February to June 1974). This report details the evaluation of the system's performance duri… more

Evaluation of a Residential Solar Air Heating System. Interim Progress Report, August 1976--May 1977. [Comparison of Air-Type and Liquid-Type Collectors]

Description: The comparative performance of Solar House II collectors (air heater) and Solar House I collectors (liquid heater) is presented. In the 1976 comparison year, there is no conclusive evidence that either system provides a greater fraction of the seasonal load. Both systems were designed to provide approximately 75 percent of the annual space and water heating load, and the design targets are reasonably achieved. In February, 1976, the air system provided 65 percent of the total requirement while … more

Evaluation of the Corning and Philips Evacuated Tubular Collectors in a Residential Solar Heating and Cooling System. Final Report, 1 May 1976--1 December 1976

Description: The Solar Energy Applications Laboratory of Colorado State University has completed the design, construction, and installation of a complete set of evacuated tubular collectors on a test bed behind Solar House I. The collectors, the Corning evacuated tube collector (December 16, 1976 to December 31, 1977) and the Philips evacuated tube collector (January 16, 1978 to January 31, 1979) are being used sequentially to operate the heating and cooling system of Solar House I. Data are being collected… more

Comparative Performance of Solar Heating With Air and Liquid Systems. Interim Progress Report, February 1, 1976--August 30, 1976

Description: A performance comparison between an air solar system and a liquid solar system for space heating under nearly equal conditions has been obtained. The Colorado State University Solar House I is a liquid solar system which has been in operation since August 1974. Solar House II, which stands adjacent to and has a comparable heating load to Solar House I, is equipped with an air solar system. Solar House I has been continuously monitored since August 1974 and Solar House II has been monitored sinc… more

Design, Construction, and Testing of a Residential Solar Heating and Cooling System

Description: The NSF/CSU Solar House I solar heating and cooling system became operational on 1 July 1974. During the first months of operation the emphasis was placed on adjustment, ''tuning,'' and fault correction in the solar collection and the solar/fuel/cooling subsystems. Following this initial check out period, analysis and testing of the system utilizing a full year of data were accomplished. This report discusses the results of this analysis of the full year of operation. (WDM)

Solar Supplement to Laundry Drying. Annual Progress Report, October 31, 1977--October 31, 1978

Description: A project is reported which utilizes solar energy to supplement the heating energy requirements of a large commercial type laundry dryer. Air is solar heated in flat-plate collectors and is introduced into the air intake of a dryer. The air is drawn directly from the outdoor ambient air. This system is designed for direct supply of solar heated air to the dryer with no solar heat storage. Solar heat storage could not be justified economically due to the close match in schedule between solar ava… more

Solar Evacuated Tube Collector: Absorption Chiller Systems Simulation

Description: A residential air conditioning system incorporating an Arkla Solaire absorption chiller and Corning Glass Works evacuated tube collectors is simulated and the design parameters studied. Mathematical models of the evacuated tube collector and Arkla absorption chiller based on experimental results of the components have been created and incorporated into a complete system simulation. The chiller model includes transient start-up effects and the evacuated tube collector model includes numerous opt… more

Evaluation of High Performance Evacuated Tubular Collectors in a Residential Heating and Cooling System: Colorado State University Solar House I. Report for October 1, 1976--September 30, 1977

Description: CSU Solar House I is configured with a prototype Corning evacuated tubular collector and a new Arkla lithium bromide water chiller designed for solar operation. Data have been collected for this configuration since January 1977. Prior to that time and since mid-1974, Solar House I has operated with a flat-plate collector and a previous Arkla LiBr air conditioner modified to operate in the lower solar temperature ranges. Project objectives were to develop an operating and control system for the … more

Performance of Residential Solar Heating and Cooling System With Flat-Plate and Evacuated Tubular Collectors: Csu Solar House I

Description: Measurements in Solar House I at Colorado State University have provided comparison data on space heating, water heating, and cooling by systems in which flat-plate collectors and evacuated tube collectors were used. Data were procured on 47 days during operation of the flat-plate collector and on 112 days when the house was heated or cooled by the evacuated tube collector system. It was concluded that the system comprising an evacuated tubular collector, lithium bromide absorption water chille… more
