DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a bag-like container, and a spherical container in which a latent heat accumlating material is enclosed, and a heat accumulating apparatus employing such containers.
BACKGROUND OF THE INVENTION
Conventionally, containers or vessels in which a latent heat accumulating material is enclosed for use in greenhouses, solar heat water heaters, etc. are presented in cylindrical, spherical or box-like configurations, and much labor and troublesome procedures have been required for installing these enclosing containers in a wide range of large areas. Meanwhile, as a result of various experiments carried out so far, it has been made clear that configurations of capsules for the cylindrical, spherical or box-like containers in which the latent heat accumulating material is enclosed, should desirably be those having a large surface area, and also a small thickness of the latent heat accumulating material (i.e. a distance from a heat conducting surface to a center of the container) so as to expedite heat transfer of the heat accumulating material accommodated therein. Accordingly, in the case of a container, for example, of a spherical shape, in order to reduce its diameter and yet, to maintain a predetermined amount of heat accumulation, it has been necessary to increase the number of capsules by that extent, thus resulting in increased cost and consequent high prices.
SUMMARY OF THE INVENTION
Accordingly, it is a primary object of the present invention to provide a heat accumulating medium enclosing bag-like container which can be easily and quickly installed by readily altering its size through cutting or external pressure according to the size of a heat receiving area, and a heat accumulating medium enclosing spherical container having a high heat accumulating efficiency, and also, a latent heat accumulating greenhouse, a water heater or the like utilizing solar heat, which is capable of saving fuel cost through employment of such containers.
It is to be noted that the present invention generally relates to a heat accumulating material enclosing container and a heat accumulating apparatus and more particularly, to improvements of heat accumulating mat materials, heat accumulating material capsules, solar heat accumulating greenhouses.
According to the present invention, there is provided a heat accumulating mat material as a heat accumulating material enclosing bag-like container in which the rectangular flat bag-like container of a flexible material is divided or partitioned into a plurality of sections through tape-like sealing portions extending in parallel relation with respect to the longitudinal side edges and lateral side edges of said container, while a latent heat accumulating substance is enclosed in each of said divided sections, with each of said sealing portions having a width sufficient to be cut without leakage of said substance. Therefore, the size of the mat can be readily and quickly altered for installation according to the size of the heat receiving surface.
Subsequently, in the heat accumulating material capsule of the present invention, a large number of heat transfer area enlarging portions are provided over the entire surface of a spherical main body, while the latent heat accumulating material is confined within the main body, with the heat transfer area enlarging portions being formed into recesses or grooves. By the above arrangement, the heat transfer area on the external surface of the capsule is enlarged, and the thickness of the latent heat accumulating material is reduced to provide a high heat transfer efficiency. Moreover, since the capsule may be formed with the recesses or grooves as the heat transfer area enlarging means during molding of said spherical main body, there is no cost-wise increase involved.
Meanwhile, in the solar heat accumulating greenhouse of the present invention, a radiator heat exchanging portion is provided at least at one side of upper or lower portion in the greenhouse, while a heat accumulating tank i
