Benefits of technology

[0049]In one aspect of the present invention, it is possible to obtain the direction of the wind necessary for designing an air utilizing apparatus, on the basis of the weather which is predicted by conducting simulations of the weather in an area which includes a location at which the air utilizing apparatus is placed, by the use of, as input data, weather information related to the area which includes the location at which the air utilizing apparatus is placed and related to a plurality of times over a certain period, even if weather data concerning the location of the air utilizing apparatus is not available.
[0050]It is also possible to provide a layout which is optimal for an air utilizing apparatus and an air utilizing apparatus which is optimally placed with respect to the calculated direction of the wind.

Problems solved by technology

Moreover, if the combustion gas in a gas turbine is returned to a suction side, the performance is significantly decreased.
Additionally, in a wind power generator, unless a desired air volume and velocity is obtained, a desired level of power is not output.

Abstract

A weather predicting method is provided and includes: selecting, from weather information including temperature data and related to times and areas, a weather information related to an area containing a location where an air utilizing apparatus is placed and related to multiple times over a certain period; by solving, with weather information as input data, differential equations expressing weather information based on weather analysis models used for conducting weather simulations, generating first narrow-area weather information related to areas smaller than the area corresponding to the weather information; selecting a second narrow-area weather information concerning an area containing the location of the air utilizing apparatus from among the first narrow-area weather information; and generating a temperature cumulative distribution or a temperature exceedance probability distribution over a certain period by using temperature data contained in the second narrow-area weather information for calculating a design temperature of the air utilizing apparatus.

Description

TECHNICAL FIELD[0001]The present invention relates to a weather predicting method and a weather predicting apparatus for reproducing, by using past weather data, weather data in an area which is smaller than an area corresponding to the past weather data. More particularly, the invention relates to a weather predicting method and a weather predicting apparatus for reproducing weather data in order to design an air utilizing apparatus to be placed in a location in which weather observation data is not available, and also to such an air utilizing apparatus.BACKGROUND ART[0002]An air utilizing apparatus which is placed outdoors under the influence of surrounding weather conditions and which utilizes air as a heating energy source or a cooling energy source, a power source, and / or a reactant is known. As an air utilizing apparatus which utilizes air as a cooling energy source, an air fin cooler, for example, is known. As an air utilizing apparatus which utilizes air as a power source, a...
