Abstract

The invention discloses an outdoor unit control circuit of a variable frequency air conditioner. The outdoor unit control circuit of the variable frequency air conditioner comprises an outdoor power supply control loop, an outdoor unit power failure detection circuit, an outdoor unit charging control circuit and an outdoor environment and coiler temperature collecting circuit. The outdoor power supply control loop is used for controlling an outdoor unit to be powered on or powered off according to an external control signal. The outdoor unit power failure detection circuit is used for detecting whether a power failure of an outdoor unit power supply circuit is caused or not. The outdoor unit charging control circuit is used for charging a filter capacitor of the outdoor unit. The temperature collecting circuit is used for collecting the temperature of a coiler of an outdoor unit heat exchanger and the temperature of an outdoor environment and outputting collected analog signals. The outdoor unit control circuit of the variable frequency air conditioner has the advantages that an outdoor unit power failure can be detected, the outdoor unit can be controlled to be powered on or powered off, the stand-by time is shortened, energy is saved, and the work stability of the air conditioner is improved.

Description

technical field

[0001] The invention relates to an outdoor unit control circuit of an inverter air conditioner. Background technique

[0002] Existing frequency conversion air conditioners are more and more favored by consumers because of their advantages such as power saving and comfort. Existing inverter air conditioners need a communication circuit to ensure the normal operation of the indoor unit and the outdoor unit. The communication circuit converts the signal from the processor of the indoor unit / outdoor unit to photoelectric conversion through the optocoupler, then transmits the electrical signal through the signal line, and then through the optocoupler, performs photoelectric conversion on the electrical signal, and the outdoor unit / indoor unit processes The receiver receives the signal and processes it. However, any damage to any of the three connecting lines, indoor, outdoor, and in the middle, will cause the air conditioner to not work properly.
