Organic Absorption Gas-Fired Residential Heat Pump

摘要

The development program of a system utilizing a new absorption pair, R133a (CF sub 3 CH sub 2 CL) as the refrigerant, and ETFE (ethyltetra-hydrofurfurylether) as the absorber fluid, is described. A diagram of the basic configuration is shown. The cooling mode (refrigerant is evaporated chilling the glycol solution which circulates to the house coil) and the heating mode (the heat is rejected by both the absorber and condenser to the glycol solution which then goes to the home) are discussed. Six units of an early hardware design were constructed and tested. Two of these units were placed in home heating service during the 1980-81 season. A market evaluation of the business potential of the absorption system was made identifying location and size of the likely market for such a system. A performance simulation analysis was performed for seven cities in the US. From these, general characteristics of the areas having the greatest performance benefits were established.
