SPRING HOT WATER SYSTEM

Japanese Patent JP2015224847

A

PROBLEM TO BE SOLVED: To provide a spring hot water system that can be applied for a plurality of bathtubs where a required flow rate of hot water and a required calory vary, a full flowing of spring by 100% is applied, a valve opening or closing control is carried out under minimum requirement and hot water of appropriate temperature can be applied in a short period of time.SOLUTION: A spring hot water system 1 of this invention comprises a source spring tank 11; a constant pressure feed water pump 12; a heat exchanger 14; thermal medium generating and circulating facility 15; a header 16 for appropriate temperature spring water; a plurality of bathtubs 19A, 19B, 19C and 19D; spring water filling flow rate adjustment valves 18A, 18B, 18C and 18D; water discharging flow rate adjustment valves 21A, 21B, 21C and 21D; and a control part 22. The control part 22 variably controls a frequency of an inverter motor 15d with a prescribed frequency corresponding to a required flow rate of hot water and a required calory for a bathtub to be used, and performs a control of increasing or decreasing of heat exchanging amount for the heat exchanger 14 and at the same time when a hot water supplying to the bath tub is started, the control part controls a hot water supplying flow rate adjustment valve and the water discharging flow rate adjustment valve.
