TWO-LOOP HOT WATER SUPPLY HELIOSYSTEM Russian patent published in 1995 - IPC

FIELD: heliosystems. SUBSTANCE: two-loop hot water supply heliosystem has collector field 1, high-velocity heat exchanger 2 and capacitance heat exchanger 3, heat-transfer agent circulating pump 4, differential thermoregulator 5 with sensors 6 and 7, as well as pressure cold water pipe line 8 and hot water pipe line 9. Tube bundle of high- velocity heat exchanger 2 is connected before heating element of capacitance heat exchanger in way of flow of heat transfer agent and inter-tube space of high-velocity heat exchanger is connected after chamber of capacitance heat exchanger 3 in way of flow of water being heated. Outlet temperature of water being heated is maintained constant due to automatic valve 10 fitted in hot water pipe line and provided with sensors 11 and tank-accumulator 12. Connected in loop of water being heated in parallel with inter-tube space of high-velocity heat exchanger 2 through three-way valve 13 is reserve heater 14. EFFECT: enhanced reliability. 2 cl, 1 dwg
