流量を変えるように成したものが試みられていた。In addition, in the case of using hot water for the brine, an attempt was made to transfer the technology for changing the rotation speed (air conditioning capacity) of the compressor to control the flow rate of hot water flowing into the heat exchanger. That is, an attempt has been made that the microcomputer changes the opening of the control valve to change the flow rate of hot water flowing into the heat exchanger according to the difference between the room temperature and the set temperature.

能力運転が可能になるものであった。(C) Problem to be Solved by the Invention In such a conventional technique, small-capacity operation with a reduced amount of hot water flowing into the heat exchanger is possible by reducing the opening of the control valve. It was
すなわち、この制御弁の開度は閉じた状態からほぼ比例
的に開くことができるので０能力付近での運転が可能に

あった。On the other hand, since the opening of the control valve is mechanically determined, frequent change of the opening facilitates the failure of the control valve, and therefore the opening of the control valve is usually changed every predetermined period. there were. Therefore, as shown in FIG. 5, when the difference between the room temperature and the set temperature is small, the change in the flow rate of the warm water becomes slow, and there is a problem that the time until the room temperature and the set temperature match becomes long.
本発明はこのような問題点に対して、制御弁の開度の変

Alternatively, it is provided with a correction means for correcting the signal to the side where the control valve is opened after the control means outputs a signal for changing from the fully closed state to the open side.

Since the correction means corrects the signal to the side that opens the control valve further, when it is necessary to increase the air conditioning capacity, the opening of the control valve can be made larger than usual without performing frequent control of the opening of the control valve. Can quickly approach the set temperature.

は省エネルギーとなる。In the air conditioner of the present invention, when the heating operation is started, the control valve (11), the signal from the microcomputer (16),
(12) is fully opened and the heat source (8) is operated.
The control for fully opening the control valves (11), (7) is performed until the set temperature [hereinafter referred to as T S ] and the room temperature [hereinafter referred to as T R ] match. Wherein T S and T control valve since the R and match (11), (12) T S and T R control in every predetermined time of opening of the
According to the difference between. If T R is higher than T S , the microcomputer (16) outputs a signal for controlling the opening of the control valves (11), (12) to decrease. In this case, the proportion of reducing the degree of opening is larger and the difference between T R and T S is large, T R
If the difference between T S and T S is small, it is reduced. When the opening of the control valves (11) and (12) is controlled by the microcomputer (16) and the openings of the control valves (11) and (12) are now fully closed, the microcomputer ( 16) is a heat source (8)
The signal to stop the operation of is output. As described above, when the control valves (11) and (12) are fully closed, the operation of the heat source (8) is stopped. Therefore, even if the control valves are fully closed, the operation of the heat source is stopped. The present invention is more energy-saving than the conventional one which has not been used.

TRがTSより低下すると、マイクロコンピュータ（16）は
制御弁（11），（12）を開くように信号を出力すると共
に、熱源（８）を運転させるように信号を出力する。The control valves (11) and (12) are controlled to be fully closed, and
When T R becomes lower than T S , the microcomputer (16) outputs a signal to open the control valves (11) and (12) and a signal to operate the heat source (8).

る。従って、本発明では、制御弁が全閉と制御され設定
温度より室内温度が低下した後の立上り時間（室温が設
定温度に収束する時間）を短くすることができる。At this time, the microcomputer (16) does not control the opening of the control valves (11), (12) according to the difference between T R and T S as in the conventional one, but rather the control valves (11), (12) is a predetermined opening [eg 5 steps of the above steps]
Correct the signal to open. As described above, in the air conditioner control device of the present invention, when the control valves (11) and (12) are opened from the fully closed state, the microcomputer (16) causes T R and T S
Since the control valve regardless of the difference to correct the signal such that the opening degree is determined, the opening degree of the control valve, as described above T S and T R
The opening of the control valves (11) and (12) is controlled to be larger than that of the conventional one, which is determined according to the difference between and, and the amount of heat exchange in the heat exchanger (7) increases. Therefore, in the present invention,
The time when T R approaches T S becomes faster than the conventional one. Therefore, in the present invention, it is possible to shorten the rise time (the time for the room temperature to converge to the set temperature) after the control valve is controlled to be fully closed and the indoor temperature falls below the set temperature.
また、制御弁（11），（12）が全閉後再び開成制御され
た後の制御は、TSとTRとの温度差により制御弁（11），
（12）の開度が増減制御される。Further, the control after the control valves (11) and (12) are fully closed and then controlled to be opened again is controlled by the temperature difference between T S and T R.
The opening of (12) is controlled to increase or decrease.
尚、冷房用の構成として圧縮機（１）を用いた冷媒回路
の変わりに、チラー（17）等を用いても構わない。A chiller (17) or the like may be used instead of the refrigerant circuit that uses the compressor (1) for cooling.
尚、制御弁（12）は省略しても構わない。The control valve (12) may be omitted.
（ト）発明の効果 以上のように構成された本発明の制御装置では、制御手

きの立上り時間を短くすることができる。Further, when the control valve is fully closed or changes from the vicinity of full close to the open side, the opening of the control valve is corrected from the opening calculated by the control means by correcting the opening of the control valve to the open side by the correction means. Therefore, it is possible to control the opening degree of the control valve when the room temperature changes around the set temperature in the direction in which the air conditioning capacity is obtained, without frequently controlling the opening degree of the control valve. Therefore, the control valve is controlled with a larger opening than the conventional one in which the opening of the control valve is controlled according to the temperature difference between the indoor temperature and the set temperature. The time to bring the temperature close to the set temperature can be shortened. As described above, in the present invention, the control valve is controlled to be fully closed, and when the room temperature is lower than the set temperature, the opening degree of the control valve is not frequently controlled, so that the control valve is prevented from malfunctioning. The rise time at this time can be shortened.
