Combined heat recovery air conditioning unit

Abstract

The invention provides a combined heat recovery air conditioning unit, and belongs to the technical field of air conditioners. The combined heat recovery air conditioning unit comprises a mounting box, a first layer cavity and a second layer cavity are formed in the mounting box, an exhaust air outlet and a second electric air valve are arranged at the left end of the mounting box, and an exhaustair inlet is formed in the rear end of the mounting box. A fresh air outlet is formed in the upper end of the mounting box, an exhaust pipe is connected to the upper end of the fresh air outlet, an exhaust cylinder is arranged at the upper end of the exhaust pipe, a galvanized plate air return pipe is arranged at the rear end of the exhaust pipe, and the other end of the galvanized plate air return pipe is connected with the exhaust air inlet. An exhaust fan, a first surface cooling water retaining section, a first electric air valve and a first plate type G filter are sequentially arranged inthe first layer cavity from left to right. By means of the combined heat recovery air conditioning unit, fresh air energy consumption can be reduced, meanwhile, the air conditioner load is reduced, and therefore the operation cost of air conditioning equipment is reduced, exhaust air and fresh air are combined, and cross contamination is avoided.
