Abstract

PURPOSE: A method for generating electricity using the temperature difference between days and nights with air heat storage is provided to infinitely generate heat, and to generate the electricity with natural heat. CONSTITUTION: A method for generating electricity using the temperature difference between days and nights with air heat storage comprises following steps. A heat storage tank is installed to store sensible heat at night or days. An insulation material is attached to the outer wall of the heat storage tank, and the materials in the storage tank mixes liquid and solid. The heat storage tank comprises a pipe in which the air flows. A fan blows out the air, and stores the air heat. The cold heat stored at night is used as an evaporation heat source for a boiler, and used as a condensation heat source. The heat stored in the day time is used as a heating source for the boiler at the night.

Description

공기열저장고를 이용한 낮과밤의 온도차발전{omitted}Day and night temperature differentials using air heat storage

낮에는 밤의 낮은온도를이용하여 발전을 하고 밤에는 낮의 높은온도를 이용하여 발전하기위하여 낮이나 밤등의 현열을 저저장고에 저장한다To generate electricity by using the low temperature of the night during the day, the sensible heat of day or night is stored in the low storage room to generate the electricity by using the high temperature of the day.

저장방식은 액체와 고체등을 혼합하던지 또는 액체만을 가진 단열재를 외벽에 부착한 밀폐한열저장고를 설치하되 이저장고에는 이것을 관통하는 공기가 흐르는 관을 설치하여 밖의 공기가 팬으로 불어 반대편등으로 배출할 수가 있게한다 그리하여 밤의 낮은공기열을 저장하기위하여 한밤에열저장물질을 함유한저장고를관통하는 관을 팬으로 밖의 차가운공기가 흐르게하여 반대편으로 나가게하여 열저장고에 열을 전달하게한다 이리하여 저장고의 함유한 물등을 온도를 낮게하여 낮까지 보존한다 낮에는 발전을 위하여 증발조를 낮의 더운공기로 비등케하여 응축조의 터어빈을돌린 증기등을 이저장고의 차가운열량을 열교환관을 통하여 회수하여 그냉열로 응축케 하는 것이다 현재 온도차발전은 온도차가 10c이상이 되면 발전이 가능하다 따라서 이방식은 사막지방에서 가장유용한방식이다 위열저장고를 별도로두어 낮의 더운공기열을 저장할수있도록하여 그더운온도를 위와같이 하여 저장하고 밤에 그열로 보일러를 돌리고 응축조의 냉각을 위하여 차가운 밤의 열을 이용하여 냉각 할 수가 있다 이 방식은 열을 모으기위하여 들어가는 동력은 팬가동동력만 필요하다 태양열발전과 다른점은 집광판이 필요가 없다 발전효율은 낮지만 열량이거의무한대로있으므로 생상성이 높다고 본다The storage method is to install a sealed heat storage system that mixes liquid and solid, or attaches only liquid insulation to the outer wall, and installs a pipe through which air flows through it, and the outside air blows into the fan to discharge to the other side. Thus, to store the low air heat at night, a pipe through the reservoir containing the heat storage material at night is allowed to flow out to the other side by passing the cold air out of the fan to the other side to transfer heat to the heat storage. The water contained in the tank is kept at a low temperature and stored until the day. During the day, the evaporator is boiled with hot air for the day to recover steam from the condensate's turbine through the heat exchanger tube. Current temperature differential power generation is possible when the temperature difference is more than 10c. The method is the most useful method in the desert area. The heat storage is set aside so that it can store the hot air heat of the day so that the hot temperature is stored as above, turn the boiler to the heat at night and use the cool night heat to cool the condenser. This method requires only fan driving power to collect heat. Unlike solar thermal power generation, there is no need for a light collecting plate. The power generation efficiency is low, but since the heat quantity is almost infinite, the productivity is high.
