That is, (a) the rise in the room temperature and the unevenness in temperature in the upper, lower, left and right directions are remarkable. (B) The burden on utilities is large due to wasteful capital investment and wasteful energy consumption of air conditioning. (C) Since the feet are cold and an electric heater or the like is used, the electricity fee increases, and a breaker down causes trouble for the OA network and the like. (D) Many people complain of physical problems, especially women. For this reason, work efficiency is reduced. (E) The occurrence rate of M / C troubles in personal computer-related devices and OA devices increases. Conventionally, there are such various problems.

Hereinafter, the usage method for each season will be described. As shown in FIG. 6, in the summer, the cool air from the air conditioner 1 naturally falls downward from the ceiling side. By generating an airflow of 0.3 to 0.5 m / s by the airflow generation device 12, even if the temperature setting of the heating / cooling device 3 is increased, the user can feel cool. In the winter season, when the airflow generating device 12 generates an airflow of 0.1 to 0.3 m / s, the user can feel warm even if the temperature setting of the air conditioning is set low. In particular, it is effective to use the underfloor heating device together. In the interim period, when the blowing of the heating / cooling device 3 is stopped, and the blowing fan 23 and the airflow generating device 12 are operated to generate a weak airflow (0.2 m / s) in the room, the user can feel comfortable. . As shown in FIG. 6, by using an air conditioner equipped with the air conditioner 1, temperature unevenness can be eliminated in both summer and winter, and a comfortable temperature environment can be created.
