This is achieved by lowering the set air blowing temperature and reducing the fan power to save energy when the room temperature remains within the appropriate range for a certain period of time when the fan is controlled at an appropriate opening degree.
以下、図面について本発明の実施例を詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.

ステムを実行させる。FIG. 2 is a flowchart showing an embodiment of the method of the present invention,
A program for optimally starting the air conditioning system is input into a microcomputer, minicomputer, etc., and controls various controllers to run the air conditioning system.

(step mouth). Pre-cooling or pre-heating is a separate program that cools or heats the room for a pre-calculated period of time in order to bring the room temperature to the appropriate temperature by a predetermined time in the morning when people begin to be active. This is the optimal start-up operation, but if you want to avoid deciding how many hours in advance to turn on the air conditioner and always run the air conditioner for an extra set amount of time, follow this program. This does not apply to the operation of

(stenopbo).

くステップへ、ト)。First, let's talk about the summer when there is no need to switch. The air conditioner operates in cooling mode, and VAV 3.3'--- is used to control the room temperature, but in reality there is considerable variation in the indoor temperature. Therefore, the initial value [TC'] of the air blowing temperature is set to a predetermined daily temperature without taking into account the actual room temperature using a temperature sensor, etc.

ウンタは帰零される(ステップヌ)。Thereafter, while measuring the actual room temperature using the temperature sensor 14 shown in FIG. 1, the measured room temperature (TR) is controlled to match the target temperature (rRv) determined for each sword or season. At this time, the measured room temperature (TR) is the target set temperature (TRV) - correction value [α2] (approximately 1'c
degree), i.e., VAV 3 ,
3'----17) If the room temperature still falls while the opening degree is kept at the minimum opening degree (50%), set VAV3, 3'
In the case of -・-, the current set air temperature (TC) is slightly raised in order to bring the room temperature, which is too low to be controlled, to the appropriate temperature (stesople). As a result, the cold water coil 1b is throttled, the temperature of the air being blown increases, and the problem of excessive cooling is eliminated. Note that before such control is performed, a counter described later is reset to zero (step nu).

If it is within ±correction value [α2], that is, in this case, ν^V3.3'---- is the opening degree of 50% to 100%.
% and optimal control is achieved, but if this state of proper temperature control continues for a certain period of time, the set air temperature CTCJ will be lowered (stenob force). Whether or not it continues for a certain period of time is determined by using a counter and determining whether or not this counter has been activated a predetermined number of times.As mentioned above, if the condition is no longer met midway through, the count must be restarted from the beginning (step o .

ギー化が図れる。w). When the set air temperature (TC) decreases, the room temperature also decreases and VAV 3, 3' --- also closes a little. As a result, the pressure inside the duct 2 increases, and the pressure sensor detects this and reduces the rotation speed of the blower 1c, thereby saving energy.

If it is larger than the correction value [α2], the counter is also reset to zero, and then the set air temperature [TC] is lowered to further cool the room to avoid leaving the proper environment.

役立つ。By the way, Figure 3 shows room temperature and duct 2 based on elements over time.
This figure shows an example of the relationship between the temperature and the temperature of the air, but as can be seen from this figure, when control is performed based on the temperature of the air, it takes some time for the results to be reflected in the actual room temperature. A deviation occurs, and the control is particularly useful for adjusting this deviation.

ン)。Next, when a switching mode between heating and cooling is required, the mode is divided into VAV 3, 3' --- depending on whether the control is performed by fixing it to full open (referred to as CAV) or the mode is VAV 3, 3' --- (steel control),
CAV is mainly the degree of heating mode. In the case of the CAV mode, the target room temperature (TI?C) is compared with the ventilation temperature C1'D) in the CAV mode, and TI] is TlIC-α
If it is equal to or smaller than I (corrected value of about 1°C), the CAV switching counter starts counting, and when the predetermined number of times is reached, the mode is switched to air conditioning (VAV).
steptsu, ne, su). This is because the room temperature is always higher than the air temperature, and cooling is more necessary than heating. Since it is impossible to suddenly set the air temperature to a considerably low temperature at the time of switching, the air temperature for cooling is first maximized, and then control is continued according to the target room temperature (Stepra,

If it is smaller than or equal to the target room temperature (TRν) - correction value [α1], it is necessary to judge whether the set air temperature (TC) is the maximum value or not; if it is the maximum, that is, the air temperature If the room temperature is dropping even though the temperature is high, measure it with the VAV switching counter, and if this has reached the specified number of times and you have not switched to heating mode even once, switch to heating (CAV) mode. conduct.
