METHOD FOR DETECTION OF AIR TEMPERATURE DEPENDENCE INSIDE CLOSED OBJECT WITH FENCING STRUCTURES ON TIME WHENEVER SYSTEM OF SPECIFIED AIR TEMPERATURE MAINTENANCE INSIDE OBJECT IS DISCONNECTED Russian patent published in 2009 - IPC E04B1/74 

FIELD: construction.

SUBSTANCE: invention is related to the field of industrial and civil construction. Method for detection of air temperature dependence inside closed object with fencing structures on time whenever system of specified air temperature maintenance inside object is disconnected, in which air temperature detector is installed inside closed object to register air temperature in process of cooling. Temperature detectors are installed near all external surfaces of object fencing structures, and fan heater is installed inside object, which is used to heat air inside object until it exceeds its temperature by more than 10°C, simultaneously with heating air temperature is registered by all installed detectors, then fan heater is disconnected, and air temperature is registered by all installed detectors until it lowers by more than 5°C, afterwards, using system of heat balance equations, they calculate air temperature inside object depending on time and thermal parametres of object, after performed calculations they select those values of object thermal parametres, at which calculated air temperature inside object is most close to measured air temperature inside object, then based on selected parametres, dependence of air temperature inside closed object on time with disconnected system of specified air temperature maintenance inside object is built, using system of heat balance equations and arbitrarily setting air temperature inside object at the moment of disconnection of system for specified air temperature maintenance inside object and air temperature near all external surfaces of object.

EFFECT: invention provides for accurate detection of time when specific closed object may remain with disconnected system of specified air temperature maintenance inside closed object, not being damaged.
