Description

  The present invention relates to an indoor air conditioning panel and an indoor air conditioning system.

  Of the indoor air conditioners, what is called a so-called air conditioner generally adjusts to a desired room temperature by injecting cold / hot air into the room to generate air convection. However, since there are not a few people who feel uncomfortable by direct exposure to cold and warm air, in recent years, attention has been focused on air-conditioning apparatuses using radiation (radiation) heat. As an example, the indoor space area and the ceiling space area are separated, the air in the ceiling space area is circulated by the air conditioner, and the radiation panel installed on the ceiling is cooled or cooled by the cooling / heating medium from the air conditioner. A heated indoor air conditioning system has been developed. In this example, the temperature is controlled so that the upper and lower surface temperatures of the ceiling radiation panel are optimized by discharging the cooling / heating medium from the discharge port of the air conditioner to the upper surface of the radiation panel (for example, (See Patent Document 1). In addition, it is known that the air conditioning efficiency of the air conditioning apparatus using radiant heat is far superior to the air conditioning efficiency of a convection type air conditioning apparatus.
