FIELD: ventilation and air conditioning system.
SUBSTANCE: invention relates to an indoor ventilation and air conditioning system. Disclosed is a system (6) and a method of operation of the indoor ventilation and air conditioning system (2) with a heat source and a ventilation and air conditioning system (6) containing a source (12) of cooled air and a ventilation duct (10), while the ventilation duct (10) contains a primary inlet (24) connected to a source (12) of cooled air and an outlet (14) leading to indoor space (2). Several heat storage elements (30) are located inside the ventilation duct (10) between the primary inlet (24) and the outlet (14), so that during operation, a forced flow of cooled air can pass through the ventilation duct (10), cooling the heat storage elements (30). There is a secondary inlet (36) into the ventilation duct (10), which is connected with indoor space (2) and which, is closed by a damper (40) during operation of the cooled air source (12). The damper is designed to automatically open in a passive manner when there is no forced flow of the cooled air from the source (12) of cooled air due to the natural convection of the air flow through the ventilation duct (10). When there is the natural convection of the air flow, it is cooled by transferring heat to the heat storage elements (30).
EFFECT: invention should provide emergency cooling if the system of active cooling malfunctions particularly due to a power outage.
