The objective of Phase I is the research, development and demonstration of the basic heat pump refrigeration circuit and the heat exchange interface with the controlled and ambient environments in both cooling and heating modes of operation. The target performance characteristics for the heat pump system are a site energy COP of 0.80 for cooling and 1.50 for heating (including parasitic power consumption) at outdoor design temperatures of 95F and 47F, respectively. The basic refrigeration circuit uses a high efficiency absorption process with a novel absorbent/refrigerant pair. During the first year of this program a full sized breadboard model of the refrigeration cycle was designed and fabricated. A test program is underway. Preliminary tests indicate a cooling COP of 0.6 and a heating COP of 1.4 at design conditions, excluding electrical parasitics. In addition to the basic cycle development and test program, four hardware development and four supporting data development subcontract programs are underway. Hardware development includes interface heat exchangers, recuperative heat exchangers, a solution pump and an automatic control system. Supporting data being developed include extension of solution transport property data, corrosion control, human health assurance, and an initial market analysis.
