Development of a Double-Effect Air-Conditioner Heater (DEACH). Phase 3 and FinalReport, January 1990-December 1991. Phase 3, September 1987-December 1991. Overall Project

摘要

The report describes development efforts on a Double-Effect Air-ConditionerHeater (DEACH). Based on a double-effect LiBr/H2O absorption cycle, the DEACH was focused on residential applications with the primary objective being a low first-cost efficient gas-fired cooling system. The concept included compact integrated heat exchangers, direct heat rejection to outdoor air (no cooling tower), and ability to self-decrystallize. The performance goals of the system were essentially demonstrated in a full-scale (3 refrigeration ton), fully integrated breadboard. However, the projected manufacturing cost was somewhat above the original target and even further above that deemed competitive at the end of the project. Therefore, technical development was stopped in late 1991.
