温度ムラが生じる問題がある。 The above-mentioned type of heating/cooling equipment is a so-called central heating/cooling system.
It has been widely used as a heating and cooling system. However, the previous one, as shown in Figure 1,
A boiler is used as the heat source device a, and the hot water heated there is sent to a radiator b, such as a fan coil or floor heater, installed in each room by a circulation pump P.
Regarding the heating device A that circulates through the circulation circuit c, an adjustment valve is provided in the circuit of each radiator b to cope with differences in the heating temperature required for each room. This can be done by slightly adjusting the amount of hot water flowing into the radiator b by controlling d..., or by intermittently operating a solenoid valve provided in the circuit in place of the above-mentioned regulating valve d. In the former case, when the flow is throttled down, the temperature will change between the side of radiator B near the hot water inlet and the side near the outlet. When a large-area radiator b is used, such as in the case of floor heating, there is a problem in that the heating of the width of the room is performed locally, and in the latter case, There is a problem in that the room temperature repeatedly rises and falls, causing temperature unevenness over time.

る。 When the thermostat 5 in the valve box 2 of the automatic mixing valve V is cold when the circulation pump P is first activated, the valve mechanism 4 in the mixing chamber 3 is closed to the water inlet L.
The valve port 31 communicating with the hot water inlet H is fully closed, and the valve port 30 communicating with the hot water inlet H is fully open. The mixed water flows out from outlet M to the radiator b side. At this time, the hot water flows through the mixing chamber 3 in the valve box 2, raising the temperature of the temperature sensing part 50 of the thermostat 5 located there, and as a result, the valve mechanism 4 is activated to open the hot water inlet H. The valve port 30 communicating with the water inlet L is narrowed and the valve port 31 communicating with the water inlet L is widened. As a result, it flows through the radiator b, is cooled by heat radiation, and passes through the circulation pump P to the boiler a.
A part of the hot water that returns to the boiler flows into the mixing chamber 3 through the opened water inlet L through the branch flow path e, and mixes with the hot water flowing into the mixing chamber 3 from the boiler a through the hot water inlet H. As a result, when the water temperature in the mixing chamber 3 becomes lower than the set temperature, the valve mechanism 4 is operated to open the valve port 31 on the water inlet L side. The opening degree of the valve port 30 on the hot water inlet H side is widened to increase the temperature of the hot water in the mixing chamber 3, and the hot water flows from the mixed water outlet M to the radiator b via the mixing chamber 3. Try to maintain a constant temperature.

一定に保持される。 Therefore, the hot water flowing from the boiler a to the radiator b via the automatic mixing valve V has the temperature set in the automatic mixing valve V, regardless of the temperature of the hot water discharged from the discharge port 14 of the boiler a, and
The amount of hot water is kept constant because the amount of hot water taken out from the mixed water outlet M of the automatic mixing valve V is constant.

度に保持するようになる。(b) When the operation of the circulation pump P is set to cause hot water to flow through the circulation circuit c in the direction of arrow Y in Fig. 2, in this case, the hot water that has passed through the radiator b flows through the automatic mixing valve V. The mixed water enters the mixing chamber 3 from the outlet M, and the valve mechanism 4 is controlled by the thermostat 5 depending on the temperature of the water, and the water flows from the water inlet L through the branch flow path e without passing through the boiler a. Circulation pump P
The hot water is distributed between the hot water that returns to the hot water inlet H, and the hot water that returns to the circulation pump P from the hot water inlet H through the boiler a, and the amount of distribution is as follows.
The temperature of the hot water in the mixing chamber 3 is varied to the set temperature set by the thermostat 5, thereby making the temperature of the hot water flowing into the automatic mixing valve V via the radiator b constant. That is, in this embodiment, the temperature of the hot water exiting the radiator b is controlled to a set temperature, and the temperature of the hot water flowing through the radiator b is maintained at a predetermined temperature.
