A monitoring system for air conditioning systems based on distributed power generation and an air conditioning system using same. The monitoring system for air conditioning systems comprises a distributed power generation monitoring subsystem, a heating and ventilation energy management subsystem and a main monitoring system. The distributed power generation monitoring subsystem and the heating and ventilation energy management subsystem respectively monitor power generation status information of a distributed power generation device in an air conditioning system based on distributed power generation and power consumption status information of inherent devices in the system. The main monitoring system acquires monitoring data of the two subsystems by using a uniform first transmission protocol. In addition, the main monitoring system controls the distributed power generation device and the inherent devices in the air conditioning system according to the power generation status information and the power consumption status information.
