The use of solar energy for residential buildings in the capital city

Abstract

Taking into account the conditions of sharply continental climate of Russia the implementation of the project of heating for an apartment house can be structured on the basis of solar vacuum collectors. A diagram of the operation of the vacuum solar collectors can be considered for heating and hot water. The calculations of effective angle of solar collectors also vary for stationary use in winter and summer. Consumption of centralized heat in the spring and autumn is reduced by 30 % due to the use of solar collectors. In summer the main problem of application of solar collectors is to protect the tubes from overheating. In winter, the use of solar heating is able to provide not more than 25 % of the needs regarding the utility and the results of experimental exploitation. It is shown that the main problem of using solar energy in Russia relies not in technology, but in the legislative field. The use of a vacuum manifold in Russia will be widely implemented in areas with a cold climate and in the modern houses after solving the issues of legislative support from the state and municipal authorities.
