Abstract

PURPOSE:To prevent a heating medium from being boiled in a heat exchanger by a method wherein a burner is actuated after the opening, responding to an operation signal from a control device on the indoor side, of a heating medium feed valve is increased to an enough value. CONSTITUTION:When the one of control devices 30A and 30B on the indoor side outputs an operation signal and a relay switch is turned ON, heating medium feed valves 10 or 11 responding to an operation signal therefrom is opened. Further, a burner 2 and a circulating pump 9 are actuated in a delay by a time necessary to opening of the heating medium feed valves 10 and 11. Thus, a heated heating medium is fed only to a radiator by which necessary heating is effected, useless heat radiation can be prevented from occurring, and by circulating a heated heating medium simultaneously with the starting of combustion, a heating medium is prevented from being boiled in a heat exchanger 3. Since the heating medium feed valves 10 and 11 are opened before the starting of the circulating pump 9, water hammer noise can be prevented from generation through reduction of a difference in. a pressure between heating medium circulating passages C before and after the heating medium feed valve.

(c) Problems to be Solved by the Invention However, since the above-mentioned heating device uses a normally closed thermal valve, electric valve, or solenoid valve as the heat medium supply valve of the branch path, the heat dissipation does not require heating. No heat medium is supplied to the container, which has the advantage of preventing wasteful heat radiation. however,
Since there is a time delay for thermal valves and electric valves to fully open after energization (approximately 60 seconds for thermal valves), even if an operation signal is issued on the radiator side and combustion starts in the burner, the heat There were problems such as the medium not circulating to the radiator immediately, causing the heat medium to boil in the heat exchanger, and the temperature control device for the heat medium working, causing the burner to repeatedly start and stop. Further, when a solenoid valve is used, the valve opens instantly and this problem is solved, but there is a drawback that a water hammer sound is generated due to the pressure difference in the heat medium circulation path.

When combustion occurs, the heat medium heated in the heat exchanger (3) is transferred to the heat medium tank (5), the circulation pump (9), the outgoing header (20), the heat medium supply valve (10), and the piping connection. Enter the branch path (C1) through the mouth (21) and enter the radiator (26).
A). When the temperature detected by the heat medium thermistor (28A) reaches a predetermined temperature or higher, the cold air prevention thermoswitch (32A) is turned on and the fan motor (36A) for driving the blower fan (27A) is energized, so heat is radiated. The heat medium in the container (26A) exchanges heat with the indoor air sent by the blower fan (27A), is used for indoor heating, and then passes through the pipe connection port (17) and the return side header (19). Then return to the heat exchanger (3) and repeat the circulation shown by the solid arrow. The proportional valve control device (43) reduces the energization amount of the proportional valve (14) because the two manual forces of the NAND circuit (58) are H't and 'L', and the output is "H". , the valve opening is narrowed down to cause the burner (2) to perform weak combustion.

Only the operation switch (31B) of the indoor control device (30B>) is turned on, the room temperature thermoswitch (34B) is turned on, and the operation signal is sent from the indoor control device (30B) to the heat source side control device (16). The same applies if it is sent,
In this case, the circulation pump (9) starts after the opening degree of the heat medium supply valve (11) becomes sufficiently large, and the burner (2) starts combustion. Then, the heat medium of the heat exchanger (3) circulates to the radiator (26B) as shown by the broken line arrow, and is used for heating the room in which the radiator (26B) is installed. In addition, weak combustion is performed in the burner (2), and the amount of combustion is commensurate with the operation of one burner.

In this case, the heat medium supply valves (10) and (11) are opened, and the heat medium in the heat exchanger (3) circulates to the heat radiators (26A) (26B> as shown by solid and broken arrows, and radiates heat.

According to this embodiment, the indoor control device (30A) (30B
> issues an operation signal, and the relay switch (371
A) When (371B) is turned on, open the heat medium supply valves (10) and (11) corresponding to the operation signal, and
Since the burner (2) and circulation pump (9) were activated with a delay of the time required for the opening of the heat medium supply valves (10) (11>), heating was applied only to the radiator where heating was required. This not only prevents wasted heat radiation, but also circulates the heated heat medium at the same time as combustion starts.
Boiling of the heat medium within the heat exchanger (3) can be prevented. Moreover, since the heat medium supply valves (10) and (11) are opened before the circulation pump (9) is started, the pressure difference in the heat medium circulation path (C) before and after the heat medium supply valve is reduced. Water hammer sound can be suppressed. In addition, the number of operating indoor units (25A) (25B) is 1 to 2.
Even when the number of units is increased, the combustion amount of the burner (2) switches from weak to strong after the opening degree of the heat medium supply valve becomes sufficiently large, so when switching the combustion amount, the heat exchanger (3) There is no need to worry about the heating medium boiling inside.
