This is the third report of the series on the development of absorption type gas fired heat pumps using organic working fluids. The residential heat pumps were to provide the full heating and cooling requirements of a house down to 0/sup 0/F outdoor temperature. The subject matter of this volume concerns the design, construction, development and testing of early units for an outdoor field trial under both residential use and in continuous run operation outdoors. Simultaneously, those components of the heat pump system which had not attained full performance levels, i.e. components of the sealed absorption system and auxiliary components, were developed individually on breadboard test units to attain the design requirements for full performance. Six absorption heat pumps using R-133a and ETFE as the working fluids were designed, constructed, developed and tested as part of the field trial. Five units were operated outdoors during most of two winters and two summers, two on residences. Three were applied to the laboratory building, two of them operating on continuous run and the third on a continuous on/off cycle. The sixth unit was used for development of cycling operation to high efficiencies. Problems of operation in a northern climate were investigated during the outdoor operation of the five units during a total of 34,263 hours of operation.
