Title of the articleScrew three stage heat exchanger
Abstract.The heat exchanger is a three-tier structure in which hot water (coolant) is fed in parallel at once in three stages, and the heated water is consistently a helical screw guide in all grades. Because of this heat exchanger is able to provide the necessary heat for domestic hot water (DHW) and, simultaneously, the excess energy of the coolant can be used in the heating system, actually, what is intended for. This eliminates the need for a line of energy source, with one group of network pumps instead of two standard schemes: one line – for heating, the second – for hot water. This saves money for the purchase of hardware and operating systems, simplifying it. This design thanks to its compact size can be used in small devices, and be generating any power. Depending on the need, it can easily be turned into a four-step and more. When mounted on a carrier output levels remotely controlled shut-off devices can adjust the temperature of hot water. By the nature of the screw three-stage heat exchanger can be attributed to the rapid heat exchangers.
Keywords.Heat transfer, the heated water, coolant temperature, flow rate, channel level.
