Whole-process air handling unit and control method thereof

Abstract

The invention provides a whole-process air handling unit and a control method thereof. The air handling unit comprises an air inlet filtering section, a rotationally-started heat-exchange functional section, a fan flow-equalizing section and a muffling air supply section which are connected in sequence. The air inlet filtering section is provided with a fresh air inlet and a return air inlet. The fresh air inlet is perpendicular to the return air inlet in terms of air direction. The muffling air supply section is provided with a supply air outlet positioned on the same center line of the return air inlet. A fresh air valve, a return air valve and a supply air valve are arranged at the fresh air inlet, the return air inlet and the supply air outlet respectively. The rotationally-started heat-exchange functional section is provided with a rotationally-started heat-exchange integrated device. The fan flow-equalizing section is provided with a fan. The whole-process air handling unit further comprises a control device used for controlling rotation of the rotationally-started heat-exchange integrated device and the opening of the valves. The whole-process air handling unit can meet requirements on energy conservation and environment protection, fully utilize a fan power system thereof and serve as an accident ventilation or smoke exhaust system.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to a whole-process air handling unit and a control method thereof. Background technique [0002] In the traditional air handling unit, in its heat exchange function section, the heat exchanger, water baffle, and condensate water tray are all fixed and immovable parts, no matter whether the air handling unit is in the process of air conditioning or ventilation; Whether the exchanger and the water baffle are in the working state of the air conditioning operation process or in the stop state of the ventilation operation process, they all consume energy due to resistance loss when the air flows through. In particular, the air handling unit needs to be in the ventilation operation process due to climate change, air purification, accident ventilation or smoke exhaust, etc. The heat exchanger, water baffle and other components of the traditional air handling unit are in a state of wa...
