Heating arrangement operating with regenerated compressed air - uses four cylinders with two serving as compressors and two as drivers

摘要

The heating arrangement operates with air which is heated by compressing it. The compressed and heated air is directed to a heating radiator or boiler. The air exhausted from radiator or boiler is used for preheating the compressor inlet air. No toxic exhaust gases are produced which pollute ambient air and the compressor requires little power for air circulation. The heating arrangement has four cylinders and four pistons arranged in a row on a crankshaft. The end pistons act as a compressor pistons in cylinders each of which has two valves. The middle cylinders are used as air driven engine arrangement and these cylinders re-use the compressed and cooled air. The heater has heat exchanger for preheating compressor inlet air.
