(C) Problems to be Solved by the Invention By the way, since the above-described heating device uses the normally closed thermal valve or the motorized valve as the heat medium supply valve of the branch path, the radiator that does not require heating is used. There is an advantage that a heat medium is not supplied and wasteful heat dissipation can be prevented. However, when the heating medium circulation path is filled with liquid as in the initial use, the radiator side (indoor side) is forced to generate an ON signal and all the heating medium supply valves are opened before the liquid is supplied. I had to put up the tension and this work was very troublesome. In addition, since it has a plurality of branch passages, it is necessary to inject the heat medium into the heat medium circulation passage using a pressure pump having a large pressing force.

When the heating medium circulation path is filled with liquid as at the beginning of installation,
Even if the indoor control device does not issue an operation signal, the trial operation control device of the heat source side control device selects and opens any one of the heat medium supply valves of the respective branch passages, and opens the circulation pump. While operating, a pressure pump is connected to the liquid supply port to inject the heat medium into the heat medium circulation path. The heat medium that has entered the heat medium circulation path sequentially flows to the circulation pump, the branch path where the heat medium supply is open, and the heat exchanger, and the air in the heat medium circulation path is discharged from the exhaust port. Next, when only the remaining heat medium supply valve is opened by the test operation control device and the circulation pump is operated, the heat medium is injected into the remaining branch passage, and the air in the branch passage is discharged from the exhaust port to the outside. Is discharged to. As described above, according to the present invention, since the heat medium supply valve is opened by using the trial operation control device of the heat source device and the circulation pump is operated, the pressure pump is connected to the liquid supply port. It is possible to fill the entire heat medium circulation path with liquid while successively injecting the heat medium into each branch path. For this reason, not only the liquid filling work can be easily performed on the heat source machine side, but also a pressure pump with a small pressing force can be used for the liquid filling. In addition, claim 2
In the heating device described above, the heat medium circulation path becomes a closed circuit, the evaporation of the heat medium is small, and usability is improved.

When it is confirmed that the heat medium flows into the reserve tank (8), the plug (62) is replaced with the outlet (63B).
At this time, the heat medium supply valve (10) is closed, and instead, the heat medium supply valve (11) is opened by energizing the relay (59), and the circulation pump (9) is operated. Therefore, the heat medium injected from the pressure pump (61) into the heat medium tank (5) flows through the branch passage (C2) as indicated by the dashed arrow.
Then, when the branch medium (C2) is also filled with the heat medium and the pressure in the heat medium tank (5) rises again, the air in the heat medium circulation path (C) is exhausted from the exhaust port (67) of the reserve tank (8). ), The heat medium further flows from the heat medium tank (5) into the reserve tank (8), and the liquid filling is completed.

Only the operation switch (30A) of the indoor unit (25A) is turned on,
When the thermo switch (32A) is turned on, the fan motor (34A) is energized and the blower fan (27A) operates. Also, the relay switch (351A) is closed by energizing the relay (35A). At this time, in the operating number discriminating device (36) of the heat source side control device (16), a constant voltage is generated at the connection point (46), the transistor (55) is turned on, and the relay (5
6) is energized and the heat medium supply valve (10) is opened. Further, since the voltage V C of the power supply line (65) enters the input terminal (IP) of the combustion control device (38) via the diode (52), the combustion control device (38) has a predetermined sequence.
7), shutoff valve (13), proportional valve (14) and ignition device (15)
Is operated to start combustion in the burner (2), and a pump drive signal is supplied to the pump drive device (39) to turn on the transistor (60) to operate the pump (9). Then, the heat medium of the heat exchanger (3) heated by the burner (2) flows as shown by the solid line arrow, and the heat radiator (26
It is circulated to A) and used for heating the room where the indoor unit (25A) is installed. In this case, one input of the NAND circuit (48) is “H”, the other input is “L”, and the output is “H”, so the energization amount control circuit (49) receives this output signal. The amount of electricity to the proportional valve (14) is reduced to cause the burner (2) to perform weak combustion.

According to this embodiment, one of the heat medium supply valves (10) (1) is used by using the trial operation control device (41) in the heat source side control device (16).
Since 1) can be opened and the circulation pump (9) can be operated, indoor operation switches (30A) (30B) and thermoswitches (32A) (32B) are operated as before.
It is possible to easily perform the liquid filling work of the heat medium on the heat source device (1) side without forcibly turning on the heat medium and opening the heat medium supply valves (10) and (11). In addition, branch road (C1) (C
While injecting heat medium into 2) sequentially, heat medium circulation path (C)
Since the whole is filled with liquid, the pressure pump (66) may have a small pressing force, and it is possible to use a commercially available atomizer. Further, the hot liquid tank (5) is provided with a liquid supply port (23) with a check valve (24), and the heat medium tank (5) is connected with a reserve tank (8) via a pressure adjusting valve (7). Since the air is vented from the exhaust port (67) of the reserve tank, the heat medium circulation circuit (C) becomes a closed circuit, the heat medium evaporates less, the heat medium can be used for a long time, and the liquid supply port Even if you forget to put the lid on (23), you do not have to worry about liquid leakage. Furthermore, the trial run controller (41)
Then one plug (62) and a pair of outlets (63A) (6
3B) is used to switch the switch, so not only is its operation easy, but the heat medium supply valve (10) is mistakenly used.
There is no need to worry about opening (11) at the same time.
