Description

  The present invention relates to a radiation type air conditioning system.

  Conventionally, a convection air conditioning system using air as a medium is generally used as an air conditioning system that performs indoor air conditioning. On the other hand, as for the blind installed on the window side of the room, it is general to adopt a blind in which the inclination angle of each blade is constant and can be opened and closed by moving up and down and changing the inclination angle of the blade ( For example, see Patent Documents 1 and 2). For this reason, on days with strong solar radiation, the blinds are lowered to block the entrance of solar radiation, thereby preventing the glare of outside light and the invasion of heat due to direct solar radiation.

  By the way, when considering an air conditioning system using both the convection air conditioning system and the blind, the following two problems arise. First, since the blind for blocking solar radiation also blocks visible light, it is not possible to fully utilize outside light. For this reason, lighting by the window is necessary even in the daytime, which leads to an increase in illumination energy consumption.

  Secondly, although solar radiation can be blocked, infrared rays, which are heat components of solar radiation, are taken into the room and the heat load of the perimeter increases. For this reason, a dedicated air conditioning system for the perimeter is required, leading to an increase in air conditioning energy consumption.

  This invention is made | formed in view of the above, Comprising: It aims at providing the radiation type | formula air conditioning system which can suppress the energy consumption of room lighting and an air conditioning.

  In order to solve the above-described problems and achieve the object, the radiant air conditioning system according to claim 1 of the present invention is a blind provided on a window surface into which sunlight is inserted, and adjusts daylighting into a room. A number of horizontally extending blades are arranged at intervals in the vertical direction, so that the sunlight reflected by the blades is directed toward the ceiling at the back of the room as the upper blades are directed toward the ceiling at the back of the window. A blind panel in which the inclination angle of the lamp is sequentially changed from the upper blade to the lower blade, and a radiation panel for cooling and heating provided on the ceiling surface to which sunlight reflected by the blade is directed and having a function of absorbing infrared rays. It is characterized by providing.

  A radiant air conditioning system according to claim 2 of the present invention is the panel according to claim 1, wherein the radiant panel has a cold / hot water pipe connected to an outdoor heat exchanger, and the temperature can be adjusted. It is characterized by being.

  The radiant air conditioning system according to claim 3 of the present invention further includes an outside light sensor for detecting the intensity of outside light in the above-described claim 1 or 2, and the outside light detected by the sensor. It is characterized by controlling the output of room lighting according to the intensity.

  A radiant air conditioning system according to claim 4 of the present invention is characterized in that, in any one of claims 1 to 3, the radiant panel is a member that reflects visible light.

  According to the present invention, a blind is provided on a window surface into which sunlight is inserted, and adjusts daylighting indoors. A plurality of horizontally extending blades are arranged at intervals in the vertical direction and reflected by the blades. Blinds in which the inclination angle of the blades is changed sequentially from the upper blades to the lower blades so that the sunlight is directed toward the ceiling at the back of the room as the upper blades are directed toward the ceiling at the back of the window, and the blades And a radiation panel for air conditioning that has a function of absorbing infrared rays.

  For this reason, sunlight incident on the room from the blind is reflected by the blades and uniformly illuminates the radiation panel on the ceiling surface from the window side to the back of the room. Thereby, the light radiate | emitted indoors from the radiation panel of a ceiling surface can be used as indoor indirect illumination. On the other hand, since the infrared ray of the heat component introduced into the room at the same time as sunlight is absorbed by the radiation panel, the heat load of the perimeter does not increase. Therefore, there is an effect that the energy consumption of the room lighting and air conditioning can be suppressed.

FIG. 1 is a side sectional view showing an embodiment of a radiation type air conditioning system according to the present invention.

  Embodiments of a radiation type air conditioning system according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  As shown in FIG. 1, a radiant air conditioning system 10 according to the present invention is provided on a multi-layer glass 4 (window surface) into which sunlight 2 (external light) is inserted, and the sunlight 2 is placed on a ceiling surface 8 of a room 6. A solar radiation type blind 12 to be reflected, and a ceiling radiation panel 14 for cooling and heating provided on the ceiling surface 8 and having a function of absorbing infrared rays are provided.

  The blind 12 has a large number of horizontally extending blades 16 arranged at intervals in the vertical direction, and the sunlight 2a reflected by the blades 16 is directed toward the ceiling at the back of the room B as the upper blades 16 and as far as the lower blades 16 from the window. The inclination angle of the blade 16 is sequentially changed from the upper blade 16 to the lower blade 16 so as to go to the ceiling of A.

  As such a blind 12, for example, an automatic control blind such as a gradation blind (registered trademark) that slightly changes blades one by one in accordance with the incident angle of sunlight, illuminance, and the like that change from moment to moment can be used.

  The ceiling radiation panel 14 is an air conditioning panel having a function of absorbing infrared rays, and is provided on the ceiling surface 8 toward which the sunlight 2a reflected by the blades 16 of the blind 12 is directed. The ceiling radiant panel 14 has a cold / hot water pipe 20 laid on the back side of the ceiling material 18, and the temperature can be adjusted by adjusting the water temperature and flow rate in the cold / hot water pipe 20. Sometimes it is kept at about 30 ° C. The heat of the ceiling radiant panel 14 is processed by a heat exchanger (not shown) provided outside the room through the cold / hot water pipe 20.

  On the other hand, the infrared rays of the heat component introduced into the room 6 at the same time when the sunlight 2 is taken in are absorbed by the ceiling radiation panel 14 that can be temperature-controlled. Thereby, the heat load due to solar radiation is not brought into the indoor space as heat, and heat can be removed efficiently, and the heat load of the perimeter does not increase. Therefore, both lighting energy and air conditioning energy can be expected to reduce energy consumption.

  In the above embodiment, the ceiling surface 8 (ceiling radiation panel 14) is preferably formed of a member that reflects visible light. For example, it is effective to use a white member to efficiently reflect visible light. It is.
