Field of the Invention The present invention relates to an operation control method of a floor air-conditioning system for blowing conditioned air from a floor and an air-conditioning system therefor. The present invention relates to a method and system for cooperatively controlling a device (for example, a fan coil unit or the like).

Description of the Related Art In recent years, the so-called floor-blowing air-conditioning system in which conditioned air is blown from the floor in the pursuit of comfort and suppression of floating dust has been increasing in the air-conditioning system. In the floor air-conditioning system, as shown in FIG. 3A, a closed space 3 is formed under the floor of a living room 1 and a plurality of floor outlets 7 are provided on a floor 5 and supplied to the closed space 3 by an air conditioner 9. Conditioned air is blown into the living room 1 through the floor outlet 7 and
The room 1 is air-conditioned by collecting it again from the return opening 13 provided in the air conditioner 9 through the chamber 15 in the ceiling or the duct (not shown) in the ceiling.

In particular, when the lower floor is an external condition such as a parking lot, the slab cools down, resulting in an uncomfortable air conditioning environment with cold feet. On the other hand, in the case of the floor blowing air-conditioning system, the conditioned air (warm air) blown out from the floor blowing outlet 7 can be naturally convected upward by buoyancy, and FIG.
As shown in (1), the vertical temperature distribution in the living area became almost uniform, and a comfortable air-conditioning environment without getting cold at the feet could be formed.

On the other hand, in the case of the floor blowing air-conditioning system, since the conditioned air flows from the floor to the ceiling in one direction, the filter 19 can efficiently remove smoke and dust.

調方式の快適性の向上を図ることを目的とする。However, although the above-described floor air-conditioning system has many advantages over the ceiling air-conditioning system, it is uncomfortable with the cold air blown from the feet in terms of comfort during cooling. Was sometimes sued. That is, in the ceiling blowing method, since cool air heavier than the room air can be lowered from the ceiling side by natural convection, there is a feeling of airflow from above (draft; discomfort due to hit by blowing air), but FIG. As shown in B), no low-temperature region was formed near the floor surface.
On the other hand, in the floor air-conditioning system, as shown in FIG. 5A, when the set temperature of the living room is, for example, 26 ° C.
Since the conditioned air (cool air) having a lower temperature is blown out from the floor outlet 7, if this temperature difference is large, discomfort due to the cool air may be generated in the vicinity of the floor outlet 7. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has an operation control method and an air conditioning system of a floor blow air-conditioning system capable of eliminating discomfort due to cool air blown from a floor blow outlet without lowering a cooling capacity with respect to a cooling load. The aim is to improve the comfort of the floor air-conditioning system.

t3), the controller 55 detects the room temperature T R of the room 21 by the thermostat 57. Next, the controller 55
If it is determined that the set temperature of the interior system, that is, the floor outlet air conditioner set temperature T FS is lower than the room temperature T R -1 ° c (st5), the perimeter air conditioner set temperature T PS is lowered (for example, T PS- 1 ° c), the cooling output of the perimeter air conditioner 49 is increased (st7). As a result, as a result, the floor blowing air conditioner 43 in which the cooling load is reduced has a higher blast temperature, and when the variable air volume control is performed,
The blowing amount is reduced (st9). That is, by increasing the load on the perimeter air conditioner 49, the load on the floor blow air conditioner 43 is correspondingly reduced.

温度分布となるようにする。At this time, by making the absolute value of the increased cooling output of the perimeter air conditioner 49 equal to the decreased cooling output of the floor blow air conditioner 43, the required cooling capacity for the cooling load of the living room 21 is ensured. . That is, the cooling output of the perimeter air conditioner 49, which does not easily generate a sense of airflow, is increased by the amount of suppressing the blowing of cool air from the uncomfortable feet, so that the entire room has a comfortable temperature distribution.

+ 1 ° when determining that the higher c (st11), i.e., when there is no large temperature difference and the floor blowout air conditioner set temperature T FS and room temperature T R, to maintain current the set temperature of the perimeter air conditioner 49 (st13 ). Thereby, the floor blow air conditioner 4
The air blowing temperature and air blowing amount of No. 3 are also maintained as they are (st15).
In other words, when there is no large difference between the floor outlet air conditioner set temperature T FS and the room temperature T R , discomfort due to cool air is unlikely to occur.

(st 17), that is, when the room temperature is too low, the perimeter air conditioner 49. Is raised to, for example, T PS + 1 ° C. (st19). At this time, since the room temperature is in a state of being too low, as a result, the air blowing temperature of the floor blow air conditioner 43 also increases, and when the variable air volume control is performed, the air blowing volume also decreases (st21).

As a result, the floor outlet 29

きる。As described in detail above, according to the operation control method of the floor air-conditioning system according to the present invention, the perimeter air conditioner is controlled by the control device during the cooling operation, and the difference between the room temperature and the set temperature is controlled. When is large, the load of the interior system can be processed by the perimeter air conditioner as much as possible, so that the air temperature of the floor blow air conditioner can be increased or the air volume can be reduced. As a result, the feet can be prevented from being cooled during cooling, and the comfort of the floor air-conditioning system can be further improved. Then, the increase in the cooling output of the perimeter air conditioner is one of the set temperature and the air flow,
Alternatively, by simultaneously changing the set temperature and the air volume, the operation can be easily performed with simple equipment. In addition, according to the air conditioning system according to the present invention, since the floor air conditioner and the perimeter air conditioner are provided and the perimeter air conditioner is controlled by the control device in cooperation, the floor air conditioner and the perimeter air conditioner are used. By easily and variably controlling the load ratio of the cooling output, it is possible to suppress the blowing of cool air from the floor outlet while securing the required cooling capacity for the cooling load.
