## Abstract

This disclosure is related to an air conditioning and ventilating device. An air conditioning unit, a first ventilation fan set, an inner air-conditioning fan and an outer air-conditioning fan are disposed in a cabinet. The cabinet includes a cabinet body and a partition. The cabinet body is separated into an inner chamber and an outer chamber. The cabinet body includes an inner ventilation inlet, an inner air-conditioning inlet, an inner air-conditioning outlet and an inner ventilation outlet communicating with the inner chamber. The cabinet body includes an outer air outlet and an outer air-conditioning inlet communicating with the outer chamber. The first ventilation fan set communicates with the inner ventilation inlet and the outer air outlet. The inner air-conditioning fan communicates with the inner air-conditioning inlet and the inner air-conditioning outlet. The outer air-conditioning fan communicates with the outer air-conditioning inlet and the outer air outlet.
