HEATING PLANT Russian patent published in 1999 - IPC

FIELD: heating system; heating of water. SUBSTANCE: heating plant has atmosphere air supply source, pump with electric motor, ejector, cold chamber and swirl tube whose cold end communicates with cold chamber, and hot end, with ejector. Plant has heat chamber arranged around hot end of swirl tube, heat exchanger located in heat chamber on walls of swirl tube, fixed centrifugal air separator with air and water parts, tank with water, radiator and piping system. Tank with water communicates with ejector inlet and with heat exchanger which communicates with tank through radiator. heat chamber communicates also with inlet of ejector whose outlet communicates with fixed centrifugal air separator whose air part communicates with hot end of swirl tube, and water part, with tank and with atmosphere through pipeline. Cold end of swirl tube also communicates with atmosphere. EFFECT: increased effectiveness and efficiency of heating plant owing to realization of closed cycle by air (and by water) and use of high vacuum.
