Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of a hot water heating system according to the present invention, FIG. 2 is a flowchart showing an example of an operation control main program, and FIG. 3 is a flowchart showing an example of an operation control subprogram.

A hot water heating system 1 according to the present invention is shown in FIG.
As shown in FIG. 2, a hot water type heat source unit 2 is provided, and two hot air heaters 7 and four floor heaters 8 are connected to the heat source unit 2 in parallel.

That is, the heat source device 2 is connected to the outgoing pipes 3 and 23 and the return pipe 4, and the outgoing pipe 3 is provided with two thermal valves 5. A hot air heater 7 is connected to each of the thermal valves 5 via a hot water outflow pipe 6, respectively.
A hot water return pipe 9 is connected to each hot air heater 7. Further, these hot water return pipes 9 communicate with the return pipe 4. On the other hand, four thermal valves 25 are attached to the outflow pipe 23, and the floor heater 8 is connected to each of the thermal valves 25 via a hot water outflow pipe 26. A hot water return pipe 29 is connected to each floor heater 8, respectively.
These hot water return pipes 29 communicate with the return pipe 4.

Here, the two hot air heaters 7 and the four floor heaters 8 are all installed in the same room, but are divided into two control systems in terms of control. Represents a first control system, and the floor heater 8 belongs to a second control system.

Each hot air heater 7 is provided with a hot air temperature sensor 7a, and each floor heater 8 is provided with a floor temperature sensor 8a.

A main control unit 10 is incorporated in the heat source unit 2, and the main control unit 10 includes two remote control units 11A and 11B corresponding to first and second control systems, respectively. Are connected via a signal line 12. Each of the remote control devices 11A and 11B has a room temperature sensor 2
7A and 27B are attached. Further, a signal line 13 is provided between the main control device 10 and each of the thermal valves 5 and 25.

Since the hot water heating system 1 according to the present invention has the above-described configuration, when performing heating using the hot water heating system 1, the user operates the operation switch (not shown) of the heat source unit 2 by heating. Turn on the remote control device 1
1A and 11B are operated to input the set temperatures.
In response to this, the main control device 10
Based on the operation control main program PRG1 shown in FIG. 2, the operation control of the hot air heater 7 and the floor heater 8 is performed for each of the first and second control systems.

First, the operation control main program PRG1
Step S1 starts the combustion operation in the heat source unit 2,
After the temperature of the hot water supplied to the outgoing pipes 3 and 23 is set to “medium”, step S2 of the operation control main program PRG1 is performed.
Then, by comparing the set temperature input by the remote control device 11 with the room temperature detected by the room temperature sensor 27, it is determined whether the set temperature is higher than the room temperature.

As a result, if it is determined that the set temperature is higher than the room temperature, the temperature of the hot water is changed from "medium" to "high" to raise the room temperature to the set temperature, and then the operation control shown in FIG. Each system control is performed based on the subprogram PRG2.

That is, the operation control subprogram PRG
In step S1 of 2, after the thermal valves 5, 25 are fully opened,
In step S2 of the operation control subprogram PRG2, after waiting for the flow rate of the hot water to be constant, the process proceeds to step S3 of the operation control subprogram PRG2, and the remote control device 11
By comparing the set temperature input in the step with the room temperature detected by the room temperature sensor 27, it is determined whether the set temperature is higher than the room temperature.

As a result, when it is determined that the set temperature is higher than the room temperature, in order to raise the room temperature to the set temperature, the operation valves 5 and 25 are kept fully opened and the process proceeds to step S2 of the operation control subprogram PRG2. Return. Conversely, when it is determined that the set temperature is not higher than the room temperature, the process enters step S5 of the operation control subprogram PRG2, and determines whether the set temperature is substantially equal to the room temperature.

As a result, if it is determined that the set temperature is substantially the same as the room temperature, the thermal valves 5, 25 are opened by half, and the process returns to step S2 of the operation control subprogram PRG2. Conversely, if it is determined that the set temperature is not about the same as the room temperature, the operation control subprogram PRG
In step S7 of step 2, it is determined whether the set temperature is lower than room temperature.

As a result, if it is determined that the set temperature is lower than the room temperature, the process proceeds to step S8 of the operation control subprogram PRG2, in order to lower the room temperature to the set temperature.
After the thermal valves 5, 25 are slightly opened, the process returns to step S2 of the operation control subprogram PRG2. Conversely, when it is determined that the set temperature is not lower than the room temperature, the process returns to step S2 of the operation control subprogram PRG2.

Thus, the operation control subprogram PRG
After the completion of each system control based on Step 2, the process enters step S4 of the operation control main program PRG1, waits for the flow rate of hot water to be constant, and returns to step S2 of the operation control main program PRG1.

On the other hand, the operation control main program PRG1
As a result of the determination in step S2, if it is determined that the set temperature is not higher than the room temperature, the process proceeds to step S5 of the operation control main program PRG1, where it is determined whether the set temperature is substantially equal to the room temperature. I do.

As a result, if it is determined that the set temperature is substantially equal to the room temperature, the operation control main program PRG
In step S6, the operation control subprogram PR
Each system control is performed based on G2, and the temperature of the hot water is maintained at “medium”. Thereafter, in step S4 of the operation control main program PRG1, the flow returns to step S2 of the operation control main program PRG1 after waiting for the flow rate of the hot water to be constant.

On the other hand, the operation control main program PRG1
As a result of the determination in step S5, if it is determined that the set temperature is not about the same as the room temperature, the process proceeds to step S7 of the operation control main program PRG1 to determine whether the set temperature is lower than the room temperature.

As a result, when it is determined that the set temperature is lower than the room temperature, the process proceeds to step S8 of the operation control main program PRG1 to perform each system control based on the operation control subprogram PRG2, and to lower the room temperature to the set temperature. Change the temperature of the hot water from "medium" to "low" to lower it. Further, in step S4 of the operation control main program PRG1, after the flow rate of the hot water becomes constant,
It returns to step S2 of the operation control main program PRG1.

On the other hand, the operation control main program PRG1
If it is determined in step S7 that the set temperature is not lower than the room temperature, the process returns to step S2 of the operation control main program PRG1.

Then, the hot water heated to a predetermined temperature by the heat source unit 2 is supplied to the outgoing pipes 3 and 23 and the respective hot water outgoing pipes 6 and 2.
6, the air is supplied to each warm air heater 7 and each floor heater 8 and radiated there. After returning to the heat source unit 2 via each hot water return pipe 9, 29 and the return pipe 4, the circulation is repeated. The heating operation is performed by the warm air heater 7 and the floor heater 8.

As described above, in the heating operation using the hot water heating system 1, one remote control device 1 is used in any one of the first control system and the second control system.
All the warm air heater 7 and floor heater 8 just operate 1
Can be operated, and the operability of the remote control device 11 is improved.
