Air energy-saving system for air quantity variable air conditioner

Abstract

The invention discloses an air energy saving system for a variable air volume air conditioner. The invention consists of an air conditioner unit and a direct digital controller, wherein the air conditioner unit is arranged at one side of an exterior wall of a building, one end of the air conditioner unit is connected with an air inlet trunk pipe, the other end of the air conditioner unit is connected with a blast trunk pipe, and the inlet end of the air inlet trunk pipe is provided with a fresh air inlet valve and fresh air constant volume end equipment; an exhaustion trunk pipe is connected with a return air trunk pipe, and the outlet end of the exhaustion trunk pipe is provided with an exhaustion outlet valve and exhaustion constant volume end equipment; and the inlet end of the air inlet trunk pipe, the fresh air constant volume end equipment, the outlet end of the exhaustion trunk pipe and the exhaustion constant volume end equipment are all communicated with outdoor air outside the exterior wall of the building. The air energy saving system for a variable air volume air conditioner uses the direct digital controller to determine time to start an air energy saving mode according to the outdoor fresh air state, the outdoor fresh air is sent into the air inlet trunk pipe with constant volume through operating the fresh inlet valve and the fresh air constant volume end equipment, in order to reduce the air inlet temperature of the air conditioner unit without needing to perform additional cooling to the air conditioner unit.
