Double-Effect Absorption Heat Pump. Phase 3. Final Report August 1984-December 1986

摘要

The RD&D program has resulted in design, development and testing of a packaged prototype double-effect generator cycle absorption gas heat pump for the residential and small commercial markets. The 3RT heat pump prototype has demonstrated a COPc of 0.82 and a COPh of 1.65 at ARI rating conditions. The heat pump prototype includes a solid state control system with built-in diagnostics. The absorbent/refrigerant solution thermophysical properties have been completely characterized. Commercially available materials of construction have been identified for all heat pump components. A corrosion inhibitor has been identified and tested in both static and dynamic environments. The safety of the heat pump has been analyzed by using two analytical approaches. Pioneer Engineering estimated the factory standard cost to produce the 3RT heat pump at $1,700 at a quantity of 50,000 units/year. One United States patent has been allowed covering the heat pump technology, and two divisional applications and three Continuation-in-Park Applications have been filed with the U.S.P.T.O. Corresponding patent coverage has been applied for in Canada, the EEC, Australia and Japan. Testing of the prototype heat pump is continuing, as are life tests of multiple pump concepts and long-term dynamic corrosion tests. Continued development and commercialization of gas absorption heat pumps based on this technology are recommended.
