A program to develop a cost-effective solar assisted heat pump system for space conditioning applications is described. In this system, the heat pump is the energy distribution vehicle. The collectors are relieved of this function and can now operate effectively over a wide temperature range including the lower temperatures easily developed by simple collecting structures. Thus, inexpensive collectors unsuitable for other solar heating systems can be used. This provides salient hope for cost-effectivensss. Existing heat pumps, designed for ''stand-alone'' application, are not readily adaptable to the solar assist function, and the thermodynamic potential of the series solar assist concept is destroyed by forcing this mismatch. The development and cost-effective production of properly engineered heat pumps are within the state of knowledge of the vapor compression science, and this development has been initiated by contracts. The necessary heat pump characteristics are noted, followed by a technical discussion of how these characteristics can be obtained. The ongoing work in this area is then briefly described.
