Research on mathematics "Determining the need for electricity"
In connection with vysokoystoimostyu electricity and constant growth rates arises the need for rational use of energy, that is, such its use, in which satisfied the required minimum coverage requirements. electrical work etc.. without which normal functions of an educational institution. enterprises, etc.
The aim of this work is placed:
calculation of energy needs and determining the number of lighting fixtures. neobhodimyhdlya create light, specified in the regulations.
To find solutions to this problem in this paper we consider different methods of calculating lighting, illumination determined classrooms, conducted research of the state of studying at college.
During the study found:
11.41% energy savings (14,260 kWh) per year is due to the non-performing lighting offices
According to the calculations by the method of the specific power required for college in 1302 lighting.
Izmeneniyaosveschennosti luxmeter using SW-116 showed that the contribution of existing lighting in general illumination is low and often below normal (less than 300 lux for the horizontal surface at 0.8 m
Study field illumination also showed that even during svetovogodnya in winter requires the use of artificial lighting. as priestestvennom light work surfaces (central and extreme ranks of the party and the board) covered nedostatchno, ie below 300 lux for desks and below 500 lux for the center of the board.
Analysis of the results of medical examinations showed. that the reduction of illumination leads to a deterioration of the visual analyzer
