[0025]
In offices, the heat generated by the personal computer-related equipment used causes local temperature rises and uneven temperature variations in the vertical and horizontal directions. In the summer, it is not possible to keep the entire room at a comfortable temperature using only the cooling system. There is a large temperature difference between the feet and the ceiling, and a comfortable temperature environment cannot be maintained. That is, (a) the indoor temperature rises and the temperature unevenness in the vertical and horizontal directions is significant. (B) The burden of utility costs is large due to wasteful capital investment for air conditioning and wasteful energy consumption. (C) Since the feet are cold and electric heaters are used, the electricity charges increase and the breaker down causes trouble for the OA network. (D) Many people complain of poor physical condition, especially women. This reduces work efficiency. (E) The incidence of M / C troubles such as personal computer related equipment and OA equipment increases. Conventionally, there are such various problems.
[0026]
However, the above problems (a) to (e) can be solved by using the air conditioning equipment. That is, according to the air conditioning equipment using the air conditioner 1, (a) excess thermal calories are released to the outside by an appropriate number of ventilations, so that the temperature rise is eliminated. (B) Cool and warm air can be stirred without any problem. Especially, cool air can be stirred without any unevenness, and the summer cooling effect is great. (C) Due to the weak airflow, temperature unevenness can be eliminated in the vertical and horizontal directions. (D) By constantly generating a weak airflow of 0.25 m / s (0.3 to 0.5 m / s in summer and 0.1 to 0.3 m / s in winter), air stagnation is eliminated. Comfort can be achieved. (E) Compared to the case where no air conditioning equipment is used, energy savings of 20 to 30% can be achieved, cost reduction can be realized, and environmental protection can be achieved by reducing carbon dioxide. (F) The filter 21 can remove indoor dust and odors and clean indoor air. For this reason, it is useful for the health management of people in the room.
[0027]
Below, the usage method for every season is demonstrated. As shown in FIG. 6, in the summer, the cool air from the air conditioner 1 naturally falls downward from the ceiling side. Even if the temperature setting of the heating / cooling device 3 is increased by generating an air flow of 0.3 to 0.5 m / s by the air flow generation device 12, it can feel cool. In winter, when the airflow generator 12 generates an airflow of 0.1 to 0.3 m / s, it can feel warm even if the temperature setting of the air conditioning is lowered. In particular, it is effective to use an underfloor heating device in combination. In the intermediate period, it is possible to feel comfortable by stopping the air blowing of the heating / cooling device 3 and operating the blower fan 23 and the airflow generation device 12 to generate a weak airflow (0.2 m / s) in the room. . As shown in FIG. 6, by using the air conditioning equipment provided with the air conditioner 1, it is possible to eliminate temperature unevenness and create a comfortable temperature environment in summer and winter.
