トへの通水はそのまま行なうという制御となっていた。Conventional technology Traditionally, when installing air conditioning equipment in buildings, etc.
The cold/hot water machine that serves as the heat source and the fan coil unit that serves as the terminal device are connected by piping to the indoor side, and this piping connection passes through a main pipe within the piping space of the building, and from this main pipe to each fan coil unit in the room. They are connected by a branch pipe, and this branch pipe is equipped with an electric valve that is opened and closed by an automatic temperature control device. These heating and cooling systems were controlled as follows. In other words, the water temperature detection sensor installed in the branch pipe
When the air temperature sensor switches between cooling and heating modes, and when the room temperature detected by the room temperature sensor installed at the indoor air intake of the fan coil unit reaches the set value, the blower stops operating, and at the same time, Close the electric valve to stop water flow to the fan coil unit, or
Alternatively, the control was such that even if the blower was stopped, water continued to flow to the fan coil unit.
発明が解決しようとする問題点
上記従来の構成では、送風機を停止し、電動弁を閉とす
る通水停止の場合には、朝一番等の立ち上がり時におい
ては次のような不具合がある。Problems to be Solved by the Invention In the above-mentioned conventional configuration, when water flow is stopped by stopping the blower and closing the electric valve, there are the following problems when starting up, such as first thing in the morning.
すなわち、暖房シーズンで支管に設けた水温検出センサ

があり、この温度が、たとえば、16°C1室温センサ
ーによる検出された室内温度が、10°Cの場合は、操
作スイッチを入れて暖房しようとしても、前述の水温検
出センサーによる暖房選択水温が26°C以上であるか
ら、暖房モードを選択、 してしまう。した
がって、室内設定温度を、たとえば20″Cと設定すれ
ば、検出室内温度が10°Cであるから、送風機も運転
しない。また電動弁も閉のままであり、暖房運転しより
としても、暖房と接続した支管の水温が、室内の温度、
たとえば30°C程度になっていて、水温もほぼ同等の
3゜°C程度となっている場合には、検出水温が26°
C以上であるから、暖房モードになシ、冷房運転が不可
能となる場合が生じる問題点があった。In other words, during the heating season, if the water temperature detected by the water temperature sensor installed in the branch pipe is 26°C or higher, heating will be selected, while if the temperature detected by the room temperature sensor is below the arbitrarily set temperature, the blower will not operate. When the temperature exceeds the set temperature, the blower stops, and the electric valve also operates in conjunction with the blower to perform heating while opening and closing water flow to the fan coil unit. If the branch pipe is long, the temperature near the fan coil unit may be lower due to this long branch pipe distance, and this temperature may be lower than 16°C, for example if the room temperature detected by the room temperature sensor is 10°C. In case C, even if you turn on the operation switch and try to heat the room, the water temperature selected for heating by the water temperature detection sensor is 26°C or higher, so the heating mode is selected. Therefore, if the indoor temperature setting is set to 20"C, for example, the detected indoor temperature is 10"C, so the blower will not operate. Also, the electric valve will remain closed, and even if heating operation is to be performed, the air blower will not operate. The water temperature of the branch pipe connected to the indoor temperature,
For example, if the temperature is around 30°C and the water temperature is about the same, around 3°C, the detected water temperature is 26°C.
C or higher, there was a problem in that heating mode could not be activated and cooling operation could not be performed.
さらに、前述の従来例の後者、すなわち送風機を停止に
するが、ファンコイルユニットへの通水ヲそのまま続行
する場合は、冷房時に、常時通水されている冷水により

表面に、結露が生じる等の問題点があった。Furthermore, in the latter case of the conventional example described above, in which the blower is stopped but water continues to flow to the fan coil unit, the cold water that is constantly flowing through the fan coil unit during cooling will cool the body of the fan coil unit. There were problems such as condensation forming on the surface of the aircraft.

0N−OFFに追随しながら電動弁7が開閉する。In the above configuration, when a fan coil system is installed in a building, Daisei Mansicon, etc., the operation switch of the fan coil unit 1 is turned on to perform heating. During this heating process, when the first operation switch is turned on in the morning at the beginning of the day, the blower 3 is turned on as shown in Figure 2.
From point A, which is FF, it turns on for 1 minute and then turns off immediately.
Return to - The blade type valve 7 is operated at the same time as the operation switch is turned on.
Point A remains open for 92 minutes, and the water in the outgoing pipe 4 flows through the outgoing pipe 6.
It flows through the heat exchanger 2 and the branch pipe 11, and then it is closed for another 6 minutes, opened for another 2 minutes, and closed for another 6 minutes. By repeating this, the temperature of the hot water flowing through the outbound pipe 4 will be
The water flows through the outgoing branch pipe 6 to the heat exchanger 2, and its temperature is detected by the water temperature detection sensor 8 to confirm that it is in the heating mode. In other words, due to this intermittent operation, main pipes 4 and 6
Let the hot water of the fan coil unit 1 side and the hot water of the fan coil unit 1 side have approximate temperatures. Then, the blower 3 is continuously operated and the electric valve is continuously opened. In short, at the first rise in the morning, Ojokan 4
In this case, the water is high temperature, but because the branch pipe 6 is long near the heat exchanger 2, the temperature is low, and the water is in cooling mode.
The electric valve 7 is opened and closed intermittently, and the water temperature detection sensor 8 detects the hot water temperature of the return pipe 4, thereby preventing the cooling mode and accelerating the start-up. Next, after the start-up operation of the first adjustment, as shown in FIG. 3, the blower 3 continues heating operation from point B, and the (ON)%
It is also open from four points. Then, when the room temperature detection sensor 1o reaches the set temperature, the blower 3 is turned off and stopped, and the electric valve 7 is closed.After this, the electric valve 7 opens and closes while following the ON-OFF state of the blower 3.
したがって室温検出センサー1oによって長時間、送風
機3が停止した時、熱交換器2の近傍では電動弁7が間
歇運転を行なっているから、往生管4の水温を感知して
いる。Therefore, when the blower 3 is stopped for a long time by the room temperature detection sensor 1o, the electric valve 7 is operating intermittently in the vicinity of the heat exchanger 2, so the water temperature in the recirculation pipe 4 is sensed.
また、これは冷房シーズン中における冷房運転も同様で
あり、特に中間期に、暖房したいにもかかわらず、冷房
モードになり、また、冷房したいにもかかわらず、暖房
モードになることはなくなるのである。This also applies to air conditioning operation during the cooling season, especially in the middle of the season, when the air conditioner switches to cooling mode even though it wants to heat the air, and it never switches to heating mode even though it wants to cool the air conditioner. .

るなどの効果を発揮するものである。Effects of the Invention As described above, the present invention provides a water temperature detection sensor near the inlet pipe of the fan coil unit, a room temperature detection sensor at the suction port in the main body, and an electric valve in the piping, thereby making it possible to operate the fan coil unit. The electric valve is operated intermittently from the moment the switch is turned on, and the electric valve is operated intermittently from the moment the blower stops during continuous operation. The water temperature can be detected properly, for example, when the system goes into cooling mode when trying to heat the room,
Or, when trying to cool the air conditioner, it does not go into heating mode, or when the blower is stopped during cooling,
Since cold water is not constantly passed through the heat exchanger, it is effective in eliminating dew condensation on the surface of the fan coil unit.
