9. OPERATION DESCRIPTION

9-1. Outline of Air Conditioner Control

This air conditioner is a capacity-variable type air conditioner, which uses DC motor for the indoor fan motor and the outdoor fan motor. And the capacity- proportional control compressor which can change the motor speed in the range from 13 to 115 rps is mounted. The DC motor drive circuit is mounted to the indoor unit. The compressor and the inverter to control fan motor are mounted to the outdoor unit.

The entire air conditioner is mainly controlled by the indoor unit controller.

The indoor unit controller drives the indoor fan motor based upon command sent from the remote controller, and transfers the operation command to the outdoor unit controller.

The outdoor unit controller receives operation com- mand from the indoor unit side, and controls the outdoor fan and the pulse motor valve. (P.M.V) Besides, detecting revolution position of the compres- sor motor, the outdoor unit controller controls speed of the compressor motor by controlling output voltage of the inverter and switching timing of the supply power (current transfer timing) so that motors drive according to the operation command.

And then, the outdoor unit controller transfers reversely the operating status information of the outdoor unit to control the indoor unit controller.

As the compressor adopts four-pole brushless DC motor, the frequency of the supply power from inverter to compressor is two-times cycles of the actual number of revolution.

1.Role of indoor unit controller

The indoor unit controller judges the operation commands from the remote controller and assumes the following functions.

Judgment of suction air temperature of the indoor heat exchanger by using the indoor temp. sensor. (TA sensor)

Judgment of the indoor heat exchanger tempera- ture by using heat exchanger sensor (TC sensor) (Prevent-freezing control, etc.)

Louver motor control

Indoor fan motor operation control

LED (Light Emitting Diode) display control

Transferring of operation command signal (Serial signal) to the outdoor unit

Reception of information of operation status (Serial signal including outside temp. data) to the outdoor unit and judgment/display of error

Air purifier operation control

2.Role of outdoor unit controller

Receiving the operation command signal (Serial signal) from the indoor unit controller, the outdoor unit performs its role.

Detection of inverter input current and current release operation

Over-current detection and prevention operation to IGBT module (Compressor stop function)

Compressor and outdoor fan stop function when serial signal is off (when the serial signal does not reach the board assembly of outdoor control by trouble of the signal system)

Transferring of operation information (Serial signal) from outdoor unit controller to indoor unit controller

Detection of outdoor temperature and operation revolution control

Defrost control in heating operation (Temp. measurement by outdoor heat exchanger and control for 4-way valve and outdoor fan)

3.Contents of operation command signal (Serial signal) from indoor unit controller to outdoor unit controller

The following three types of signals are sent from the indoor unit controller.

Operation mode set on the remote controller

Compressor revolution command signal defined by indoor temperature and set temperature (Correction along with variation of room tempera- ture and correction of indoor heat exchanger temperature are added.)

Temperature of indoor heat exchanger

For these signals ([Operation mode] and [Com- pressor revolution] indoor heat exchanger tem- perature), the outdoor unit controller monitors the input current to the inverter, and performs the followed operation within the range that current does not exceed the allowable value.

4.Contents of operation command signal (Serial signal) from outdoor unit controller to indoor unit controller

The following signals are sent from the outdoor unit controller.

The current operation mode

The current compressor revolution

Outdoor temperature

Existence of protective circuit operation

For transferring of these signals, the indoor unit controller monitors the contents of signals, and judges existence of trouble occurrence.

Contents of judgment are described below.

Whether distinction of the current operation status meets to the operation command signal

Whether protective circuit operates

When no signal is received from the outdoor unit controller, it is assumed as a trouble.

Compressor operation control

Operation control of outdoor fan motor

P.M.V. control

4-way valve control

Operations followed to judgment

of serial signal from indoor side.
