Abstract
An energy saving heat transfer unit providing an efficient means to transfer energy from steam to water in a central heating system. The steam enters a mixing chamber and creates a negative pressure environment. Water in a backwater pipe, which is at a lower temperature and pressure, is than is absorbed into the mixing chamber where energy is passed from the steam to the water. A by-pass outlet is provided which relieves the heat transfer unit of excess pressure which may build up. The heated water then exits the heat transfer unit and goes back into the central heating system. After being cooled in the central heating system, the water then reenters the heat transfer unit at the backwater pipe and continues the cycle over again.
Claims6
A supersonic 4-way bypass decompressing super energy-saving unit comprising:
- a main body having a steam inlet, a backwater intake, a bypass opening, and a water exit;
- a nozzle with a critical jet at its tip located inside the body proximate to the steam inlet, a mixing chamber located adjacent to the jet, a mixing tube located adjacent to the mixing chamber, and a diffusion cubicle located adjacent to the mixing tube, the diffusion cubicle having the bypass opening located on its side;
- and
- a steam inlet flange connected to the main body and adjacent to the steam inlet, a backwater intake flange connected to the body at the nozzle, a water exit flange connected to the body adjacent to the diffusion cubicle, and a bypass flange connected to the bypass opening.
