Abstract
Industrial and scientific communities are showing a new wave of interest in developing engine-driven heat pumps that utilize hybrid sources of energy combining fossil fuels, solar energy, and waste heat. As a possible application for the Goldstone Energy Project, the performance of a 10-ton heat-pump unit using a hybrid solar-gas energy source is evaluated in an effort to optimize the solar collector size. The heat-pump system is designed to provide all the cooling and/or heating requirements of a selected office building located at the Deep Space Communication Complex, Goldstone, California. The system performance is to be augmented in the heating mode by utilizing the waste heat from the power cycle, A simplified system analysis is described in this report to assess and compute interrelationships of the engine, heat pump, and solar and building performance parameters, and to optimize the solar concentrator/building area ratio for a minimum total system cost, In addition, four alternative heating-cooling systems, commonly used for building-comfort, are described; their costs are compared, and are found to be less competitive with the gas-solar heat-pump system at the projected solar equipment costs.
