Efficient heater and air conditioner

Abstract

The purpose of this invention is to cost effectively achieve more fuel efficient cooling and heating of buildings and also provide society with the resource conservation and environmental benefits that can result from the more efficient use of our fuel resources. The invention uses conventional equipment and includes an internal combustion engine and components that are now used in electric driven compression and steam driven absorption air conditioning and heat pump systems. The work from the engine provides a direct mechanical drive for the compression cycle and most of the rejected heat from the engine is recovered and utilized by the absorption cycle, which is achieved by recovering the high and medium temperature heat in the absorption cycle generator and recovering the low temperature heat from the engine exhaust by the mixture flow stream from the absorber to the generator. The result is a direct fueled engine driven combined cycle system that can be twice as fuel efficient as existing electric driven compression or steam driven absorption systems, and that can cost effectively replace most exissting systems in large building and provide substantial resource and environmental benefits.
