温水が得られることは言うまでもない。 The operation will be explained below. First, as for the temperature inside the container, as in the past, the temperature or pressure inside the container is detected and the combustion amount of the burner is proportionally adjusted so that the temperature remains at a constant value. Furthermore, the inlet temperature and flow rate of fluids required for heating, hot water supply, and other temperature increases are measured using the thermometer 10 or 10' or the flow meter 11.
or 11', and inputs the detection signal to the control box 20 or 20'. The control box 20 or 20' calculates the amount of heat required for heating up for each outlet temperature set value based on the input detection signal, and also detects the detected value of the inlet temperature and the internal temperature from the temperature controller 8'. A logarithmic average temperature difference is calculated from the value, and the required heat transfer area of each condenser is calculated from this temperature difference and the above-mentioned required amount. The signal of this necessary heat transfer area is determined by the proportional setting device 30.
or 30', and the signal from this proportional setting device controls the control motor 40 or 40'.
The heat transfer tubes of the condensers 3 and 4 are partially covered with a heat insulating material such as silicone flexible tubes a and a', and this is expanded and contracted to transfer heat in the heat transfer tubes of the condensers 3 and 4. Change the area. That is, silicon flexible tubes a and a′ have
Control motors 40, 40' and rollers c1, 40' and rollers c1, 40', which are connected to each other by wires b and b' that drive them to expand and contract, respectively, are provided outside the closed container 1 .
c 2 , c 3 or the wires b, b′ wound around the rollers c 1 ′, c 2 ′, c 3 ′ are connected to the control motor 40,
When 40' is driven to move as indicated by arrow d, silicon flexible tubes a and a' connected to wires b and b' move as indicated by arrow d. By adjusting this movement with the control motors 40, 40', the heat exchange area of the condensers 3, 4 covered by the silicone flexible tubes a, a' can be controlled, and the outlet temperature of the heated fluid can be controlled. Control becomes possible. Finally, thermometer 1
A signal of the hot water outlet temperature detected by 2 or 12' is fed back to the control box 20 or 20', which is intended to further improve the accuracy of hot water outlet temperature control. It goes without saying that hot water at any temperature can be obtained by making the outlet temperature setting variable.

According to the present invention, even if the inlet temperature and flow rate of the fluid necessary for generating hot water change in a hot water heater or the like having multiple hot water generation circuits, a single outlet temperature can be obtained. This solves problems such as having to manually adjust the flow rate depending on the season, and the discomfort and inconvenience caused by instantaneous temperature changes in hot water supply, showers, heating equipment, etc. In addition, in the past, multiple hot water heaters were installed as dedicated units due to mutual interference between the respective hot water generation circuits, but according to the present invention, multiple circuits are installed to allow multiple hot water heaters to be used in one hot water heater. It has the advantage of being extremely economical and requiring less overall installation space.
