The multi-mode ultra-low energy consumption building kitchen makes-up air exhaust air coupling multi-stage heat recovery system relates to the kitchen ventilation technical field.The present application solves the problems of high operation cost and maintenance workload of the existing kitchen heat recovery system, increases the complexity and installation difficulty of the system, and affects the heat recovery efficiency of the system. In the normal working mode, the make-up air and exhaust air system runs simultaneously, fresh air enters the kitchen through the make-up air channel, and waste air is discharged through the exhaust air channel. When the temperature in the exhaust air exceeds the set threshold, the control system will trigger the heat energy recovery mode. In this mode, the excess heat energy will be introduced into the heat energy storage tank to store the excess heat. During the energy demand peak period, the control system will start the energy supply mode. At this time, the heat energy in the heat energy storage tank can be released to supply the additional heat energy demand. The present application realizes heat energy recovery and efficient use of energy by coupling the kitchen make-up air and exhaust air system, heat exchange and energy storage device.
