Description of the Related Art Conventionally, panel convectors and radiators which circulate circulating fluid such as water or antifreeze heated by a heating device such as a heating boiler and radiate heat by the heat of the circulating fluid to heat the room. Natural convection radiator 10
In No. 1, a natural convection type radiator temperature control valve 102 for controlling the flow of the circulating liquid into the radiator 101 at room temperature was used. This is the circulation pipe 1 that constitutes the circulation path of the circulating fluid.
The opening and closing valve is opened and closed by moving the open / close valve using the volume change of the thermowax which expands and contracts due to the change in room temperature, through the flow opening formed in the blocking wall in the connection pipe 104 connecting the heat sink 03 and the radiator 101. In addition to controlling the flow rate of the circulating fluid, the desired room temperature can be set by operating the operating member 105, and when the room temperature reaches the set temperature, the flow port is completely closed by the open / close valve.

That can heat up to
In addition, the heat radiating capacity is selected from those having a heating capacity slightly larger than the calculated load value, which is as long as possible over the width of the window 106.

温度が急激に変化してもそれにリニアに追従せずに徐々

The outlet was gradually opened and closed over 5 minutes from fully open to fully closed, and over 1 minute from fully closed to fully open.

ている時間が全開している時間よりずっと長くなる状態
となる。In most cases, the operation of the operating member on which the desired set temperature and the corresponding heating level are graduated, that is, the setting of the desired temperature, is not changed once the graduation is adjusted, and the graduation is used without change. And
If heating is performed when the temperature difference between the outside air temperature and the room temperature is small in that state, the heating capacity of the radiator that can sufficiently heat even at the lowest daily temperature will be excessive, and the distribution port will be fully closed immediately, and then fully closed. The time becomes much longer than the time when it is fully open.

温度がかなり低くなってしまうという欠点があった。Therefore, convection heat is not generated because the circulating liquid does not flow into the radiator, and the fully-closed state in which the cool air entering from the window descends steadily toward the floor surface becomes longer. The temperature suddenly drops and the temperature difference with the upper part of the room increases, and the temperature in the range of about 10 cm to 15 cm from the floor surface where the temperature control valve is installed also drops, so that the thermo wax becomes When the circulating fluid flows into the radiator again due to contraction and opening of the circulation port, the temperature near the floor surface becomes considerably low.

わせることにより流通口30を開放する。Next, the operation will be described. First, the circulation port 30 in the connection pipe 28 is connected to the open / close valve 2 as shown in FIG.
From the state where the circulating fluid does not flow into the radiator at all because the valve unit 25 is completely closed by the valve unit 25, the operating member 19 is manually turned to adjust the scale from the fully closed state of “0” to a scale of “5”, for example. Thus, the distribution port 30 is opened.

通って放熱器へと流入していく。When the operation member 19 is rotated in the fully open direction to adjust the scale, the threaded portion of the insertion portion 10 in the operation member 19 is removed from the threaded portion on the upper inner periphery of the sliding member 12. Since the member 7 moves upward, the force by which the operating rod 5 pushes down the opening / closing valve 24 becomes weaker, and the force by which the push-up spring 27 pushes up the E-ring 26 of the opening / closing valve 24 becomes stronger, so that the push-up spring 2
The opening and closing valve 24 is pushed up by the extension of 7. As a result, the valve portion 25 of the on-off valve 24 that has been in close contact with the communication port 30 in the connection pipe 28 rises, and the horizontal portion of the blocking wall 31 where the communication port 30 is formed and the distal end surface of the valve portion 25 are moved. A gap is generated, and the circulating liquid flows from the circulation port 30 to the radiator through the gap.

The amount of upward movement is increased, and accordingly, the barrier 3
The gap between the horizontal portion 1 and the tip end surface of the valve portion 25 also increases, and the amount of circulating fluid flowing increases, thereby increasing the amount of heat radiation. As described above, the circulating fluid heated by the heating boiler flows into the radiator and flows through the radiator, so that radiant heat is generated from the front of the radiator, and convection heat is generated on the upper surface of the radiator to heat the room. .

のである。In general, a natural convection type radiator such as a panel convector is installed under a window longer than the length of the window, and cold air entering the room through the window due to a temperature difference between the outdoor and the room. Is temporarily raised by convective heat generated from the upper surface of the radiator, thereby preventing cool air from flowing to the floor surface of the room, lowering the temperature near the floor surface, and increasing the temperature difference between the upper and lower parts of the room. Further, while the raised cool air descends, the cool air is warmed and convected, so that the room temperature can be raised without unevenness in the room temperature.

Then, as the thermo wax 4 expands gradually, the bellows member 3 in the temperature sensing element 1 is compressed, and the operating rod 5 is gradually pushed out. The distribution port 30 is gradually closed.

There is no, but the cool air entering from the window is on the floor from the window
Generates convection heat enough to raise without descending
In a gap where the circulating fluid flows at a flow rate
The opening / closing valve 24 moves to a position where the circulating fluid flows at a flow rate of 20 to 30% of the maximum flow rate when fully opened in this embodiment .

The shrinkage of the bellows member 3 is reduced by changing it to a smaller one.

Less than the amount, i.e. in this embodiment the flow rate at that time is less than 20-30% of the maximum flow rate, is placed below the window or the like
The convection heat generated by the radiator is too small to sufficiently raise the cold air that has entered through the window, causing a temperature difference between the top and bottom of the room, and conversely, the room temperature reaches the set temperature.
Flow rate is not enough to raise the room temperature
Of cold air coming from the window down from the window to the floor
