The electric energy metering module 3 can adopt various forms such as mechanical type or electronic type:

the mechanical electric energy metering module mainly comprises a voltage coil, a current coil, a turntable, a rotating shaft, a braking magnet, a gear, a counter and the like. The working principle is that the eddy current generated on the aluminum disc by the voltage and current coils and the alternating magnetic flux interact to generate electromagnetic force, so that the aluminum disc rotates, simultaneously, braking torque is introduced, the rotating speed of the aluminum disc is in direct proportion to the load power, the rotating speed of the turntable is integrated by the counter through axial gear transmission, electric energy is measured, and the data of the counter cannot return to zero or be tampered.

The electronic energy metering module integrates a multiplier, a P/f conversion circuit, a phase adjusting circuit, a power monitoring circuit, an interface circuit and the like.

The working principle is that a voltage sampling signal is obtained by a voltage divider, a current transformer obtains a current sampling signal, a voltage-current product signal is obtained by a multiplier, an electric energy metering pulse with frequency in direct proportion to the voltage-current product is generated by frequency conversion, the generated electric quantity pulse signal is sent to a CPU for processing by a photoelectric coupler, the electric quantity pulse signal is stored in a nonvolatile EEPROM after operation and is displayed, and data can still be stored after power failure.

As a preferred scheme, the air conditioner can set the maximum electricity consumption, and when the actual electricity consumption reaches the designed maximum electricity consumption, the circuit is automatically interrupted, so that the air conditioner is prevented from being used continuously and unsafe beyond the designed service life.

Except for the electric energy metering module, the split air conditioner capable of metering and displaying the electricity consumption comprises the following main components:

the split air conditioner consists of indoor unit and indoor unit. A refrigerant pipeline, a power line and a control line are connected between the indoor unit and the outdoor unit through a connecting terminal 10.
