AI Technical Summary

Technical Problem

The power control circuit in the air conditioning system requires a large drive current, resulting in high energy consumption. Furthermore, the communication between the indoor and outdoor units is complex, affecting communication efficiency. Existing technologies cannot enable independent communication.

Method used

By constructing an indoor-outdoor unit communication circuit in the air conditioning system and an independent first and second circuit in the patented system, which are used for signal transmission of the indoor and outdoor units respectively, thyristors and optocouplers are used to achieve independent operation of the indoor-outdoor communication circuit and prevent them from affecting each other.

Benefits of technology

This system achieves independent communication between the indoor and outdoor units by constructing independent first and second circuits in the air conditioning system, respectively. This allows communication between the indoor and outdoor units to proceed independently without affecting each other.

Abstract

The embodiment of the invention provides an air conditioning system, and relates to the technical field of air conditioners. According to the air conditioning system, indoor and outdoor communication is independently carried out through the indoor and outdoor master control circuit and the communication circuit without mutual influence. The air conditioning system comprises an indoor unit and an outdoor unit, the indoor unit comprises an indoor unit main control circuit and an indoor unit communication circuit, and the control end of the indoor unit communication circuit is electrically connected with the signal sending end of the indoor unit main control circuit; the outdoor unit comprises an outdoor unit main control circuit and an outdoor unit communication circuit. The control end of the outdoor unit communication circuit is electrically connected with the signal sending end of the outdoor unit main control circuit. The indoor unit communication circuit and the outdoor unit communication circuit comprise a first loop and a second loop; the signal sending end of the indoor unit master control circuit sends a first control signal to conduct the first loop, and the outdoor unit master control circuit receives the first signal; and the signal transmitting end of the outdoor unit master control circuit transmits a second control signal to conduct the second loop, and the indoor unit master control circuit receives the second signal.
