Title: Central supplying system for hot water
Inventor: OHASHI SHINSUKE
IPC: F24D17/00
Filed: 1993-06-30
Abstract: PURPOSE:To reduce energy for returning hot water and reheating it in a boiler and to prevent damage of a protective film in a piping by providing valve means for opening or closing in response to a temperature change and controlling a flow rate constant at the time of opening in a hot water supplying system, and controlling a return hot water amount. CONSTITUTION:A valve to be opened or closed in response to a temperature change such as a two-way valve 3 having a thermostat 4 senses a high temperature of hot water when the hot water is output from a hot water supply cock 16 to close the valve 3, thereby stopping circulation of return hot water to a return hot water pipe 33. When the hot water is not output from the cock 16, the valve senses a low temperature of the hot water to open the valve 3, continuously holds the return hot water amount flowing in the pipe 33 constant by a constant-flow rate valve 2 and suppresses flowing speed of the return hot water. Thus, energy for reheating the return hot water in a boiler 19 can be reduced, and damage of a protective film in the piping can be prevented.
