Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radiant heat radiator, which increases the energy saving effect and provides a comfortable indoor environment by effectively using radiant heat.

Conventional heat radiators such as panel radiators and radiant fan convectors radiate heat in addition to natural convection and forced convection, but the intensity of the radiant heat is not sufficient, and residents The effect of radiant heat on the human body could not be obtained unless the person lived near a radiator. Therefore, if the occupant moves away from the radiator, the radiant heat near the radiator will be wasted, or the occupant will increase the capacity of the radiator to compensate for the radiant heat that was previously being received, raising the room temperature. The disadvantage was that I had to do it myself. The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIG.

In FIG. 1, reference numeral 1 denotes a radiant heater main body, which includes a blower 2, a heat exchanger 3, a heating plate 4, etc. inside. The above heating plate 4
A heat insulating material 5 is attached to one side of the heat insulating material 5, which is detachable by sliding upward through fixed frames 6, 6' serving as height changing means. Now, if a heat medium is passed through the heat exchanger 3 to heat the heating plate 4 and the blower 2 is operated,
Indoor air is sucked in through the suction port T provided at the bottom of the main body 1, discharged from the blower 2, exchanges heat with the heating surface on the other side of the heating plate 4, and exchanges heat again with the heat exchanger 3 before reaching the air outlet. 8
More air is blown into the room. Conversely, if the heat insulating material 5 is removed from one side of the heating plate 4 in FIG. 1 and attached to the other side, the heat insulating surface of the heating plate 4 will not undergo heat exchange with the sucked air. Heat is radiated from the heating surface on the indoor side to the front side by natural convection and radiation, and only the heat exchanger 3 radiates heat by forced convection. In the embodiment shown in FIG. 2, a heat insulating material 9 is attached to one side of a heating plate 8 which is divided into a plurality of parts.If the heating plate 8 is rotated about a shaft 10 serving as a changing means, each heating surface and the heat insulating material 9 are attached to one side. The surface is reversed.

The effects of the present invention will be explained based on the above configuration.

In FIG. 3, when the radiant heater 1 according to the present invention is installed with the heating surface facing toward the indoor side, the spread of radiant heat in the indoor room 11 is as shown in 12. In other words, if you draw an isocaloric diagram of the radiant heat radiated from the radiant heater 1, you will find the range of radiant heat that actually has a radiant effect on the human body (
10KcalA^ or more) is approximately 1.
The distance is within 5m. Therefore, if there is a resident within this range, if the heating surface is directed toward the indoor side, the human body will receive radiant heat, so the room temperature can be set lower than if there is a resident outside this range. In addition, when a resident moves outside this area, the capacity of the radiant air conditioner 1 must be increased by the amount of radiant heat that has been received within the area. By directing it toward the indoor side, forced convection is performed on the heating surface, which not only increases the capacity but also prevents radiant heat from being wasted.

Furthermore, in the embodiment shown in FIG. 2, since the heating plate 8 is divided into a plurality of pieces, the amount of radiant heat can be adjusted by adjusting the number of heating plates 8 to be inverted.

As explained above, according to the present invention, it is possible to utilize the radiant heat from the radiant heater without wasting it, and at the same time, the capacity of the radiant heater itself can be used effectively, which improves comfort for the human body and saves energy. From this point of view, the effect is extremely large.
