FIELD: heating.
SUBSTANCE: in the method for determining the system of heat-engineering properties of rooms of buildings and facilities under full-scale (operating) conditions, which involves measurement of inside and outside air temperature, relative air humidity is measured inside the room and temperature is measured on internal surface of enclosing structures; dewpoint temperature and rated temperature is determined; the above temperatures are compared and that parameter is chosen, which has maximum value; the chosen value is used in radiation thermometer as lower alarm limit; radiation thermometer is used with pre-set alarm mode for investigation of the controlled zone in order to detect points with minimum temperature; density of heat flow passing through those structures is measured at those points, and corrected resistance to heat transfer of enclosing structures is calculated.
EFFECT: providing possible evaluation of heat-engineering characteristics of rooms and heat protective properties of enclosing structures under non-stationary conditions using minimum amount of recording instruments at maintaining the accuracy and increasing the monitoring efficiency.
