CALCULATION OF AIR TEMPERATURE OF GLAZED LOGGES FOR DETERMINATION OF ENERGY-SAVING EFFECT
Abstract
This article describes the features of the formation of air temperature in the spaces of glazed balconies and loggias for stationary conditions of heat exchange. There are two methods for calculating this temperature for an average air temperature of the heating period. One of these methods is based on the solution of the balance equation of the transmission heat transfers to the loggia. The second method is based on the solution of the heat balance equation with considering air exchange. There is method for calculating the energy-saving effect due to glazing of the loggia is proposed. An example is given of calculating the air temperature on a glass loggia both ways. It is obtained that the air temperature for the second method of calculation is lower than at the first. The value of energy-saving effect from the glazing of the loggia considered is estimated. When calculating the second method, it is lower than the first calculation. The second method of calculation is appropriate to use when developing a method for calculating energy consumption for heating and ventilation of residential buildings to determine their energy-saving class.
