Indoor unit overheat prevention control Once the compressor stops operating, it will not restart for 180 seconds to protect the compressor. During heating operation, if the temperature of the indoor unit heat exchanger exceeds the indoor unit heat exchanger overheat prevention temperature (about 45 to 54°C) which is determined by the operating frequency and operating status, the operating frequency is decreased by about 4 to 15 Hz. Then, this operation is repeated every 60 seconds until the temperature of the indoor unit heat exchanger drops below the overheat protection temperature. Therefore, if the operating compressor is shut down from the remote control and then turned back on immediately after, the compressor will restart after a preset delay time. (The indoor unit will restart operation immediately after the ON switch is operated on the remote control.) Compressor operation Compressor ON Compressor remains OFF for 180 seconds OFF operation on remote control ON operation on remote control Once the temperature of the indoor unit heat exchanger drops below the overheat protection temperature, the operating frequency is increased by about 4 to 10 Hz every 60 seconds until the normal operation condition resumes. Compressor can turn ON If the temperature of the indoor unit heat exchanger exceeds the overheat protection temperature for 60 seconds at minimum operating frequency, the compressor stops operating and then restarts after about 180 seconds, and the above mentioned control is repeated. Compressor ON 6. Outdoor unit overheat prevention control During cooling operation, if the temperature of the outdoor unit heat exchanger exceeds the outdoor unit heat exchanger overheat prevention temperature (about 55°C), the operating frequency is decreased by about 4 to 15 Hz. Then, this operation is repeated every 60 seconds until the temperature of the outdoor unit heat exchanger drops to about 54°C or lower. 2. Cold air prevention control When the air conditioner starts up in heating mode, the indoor unit fan will not operate until the temperature of the indoor unit heat exchanger reaches about 23°C in order to prevent cold air from blowing into the room. Also, the indoor unit fan operates at low speed until the temperature of the indoor unit heat exchanger reaches about 38°C so that people in the room will not feel chilly air flow. Once the temperature of the outdoor unit heat exchanger drops to about 54°C or lower, the operating frequency is increased by about 4 to 10 Hz every 60 seconds until the normal operation condition resumes. Indoor unit heat exchanger temperature Set fan speed If the temperature of the outdoor unit heat exchanger exceeds the outdoor unit heat exchanger overheat protection temperature for (120 sec.: outdoor temperature ≥ 40°C, 60 sec.: outdoor temperature < 40°C) at minimum operating frequency, the compressor stops operating and then restarts after about 180 seconds, and the above mentioned control is repeated. 38 35 Indoor unit fan at Ultra soft.

Compressor overheat prevention control 21 Indoor unit fan in non-operation If the temperature of the compressor exceeds the compressor overheat prevention temperature (110°C), the operation frequency is decreased by about 4 to 10 Hz. Then, this operation is repeated every 60 seconds until the temperature of the compressor drops below the overheat protection temperature (100°C). 3. Indoor unit heat exchanger freeze prevention control If the temperature of the indoor unit heat exchanger remains below 0°C for 4 consecutive minutes during cooling or dehumidifying operation, the compressor operation stops temporarily in order to prevent freezing. Once the temperature of the compressor drops below the overheat protection temperature, the operating frequency is increased by about 4 to 10 Hz every 60 seconds until the normal operation condition resumes. When the temperature of the indoor unit heat exchanger rises to 2°C or higher after about 180 seconds, the compressor restarts and resumes normal operation. If the temperature of the compressor exceeds the overheat protection temperature (for 120 seconds in cooling operation or 60 seconds in heating operation) at minimum operating frequency, the compressor stops operating and then restarts after about 180 seconds, and the above mentioned control is repeated. 4. Outdoor unit 2-way valve freeze prevention control 8. Startup control If the temperature of the outdoor unit 2-way valve remains below 0°C for 10 consecutive minutes during cooling or dehumidifying operation, the compressor operation stops temporarily in order to prevent freezing. When the air conditioner starts in the cooling or heating mode, if the room temperature is 2°C higher than the set temperature (in cooling operation) or 3.5°C lower (in heating operation), the air conditioner operates with the operating frequency at maximum. Then, when the set temperature is reached, the air conditioner operates at the operating frequency determined by fuzzy logic calculation, then enters the normal control mode after a while. When the temperature of the 2-way valve rises to 10°C or higher after about 180 seconds, the compressor restarts and resumes normal operation. 2–8 AYXPC18LR 9. Peak control 14.

PFC MODULE CIRCUIT These model’s circuit uses PFCM (Power Factor Correction Module) and IPM as the figure below for the high efficiency operation of compressor. Active filter Choke coil AC 200V Rectification circuit + Noise filter circuit Sine wave current ON/OFF Control source Voltage raise signal Compressor Driving signal Comp ressor IPM Positional detection IPM Control source IC1 29.1. PFC Module In the case the direct current is obtained by the diode bridge and smooth capacitor from the commercial power source, the current wave shape will be the pulse shape at the peak of the voltage wave shape as shown in the figure below. For this reason, the harmonic current will be generated and at the same time the power factor will be deteriorated. While monitoring the AC input voltage in the control circuit, in order to be the same phase and wave shape as this voltage wave shape, IGBT is made ON/OFF by the carrier frequency of approximately 20 kHz. By adoption of this PFC Module, the current wave shape can be made to the sine wave synchronized to the commercial power source and the power factor can be made to almost 99%. As a result of this, reactor can be disused. PFC Module works for the improvement of power factor and as the countermeasures for the harmonic current. Power-supply voltage (50/60 Hz) Current waveform (Before) Current waveform (Active filter) 29.2. PFC Module Voltage Raise Circuit The IGBT in the figure below is the switching transistor of the PFC Module. By adding ON signal to the gate of IGBT from the control IC, IGBT turns ON and the collector current Ic flows. This current flows from the + side of the diode bridge DB to the Choke coil, the - side of the diode bridge DB through IGBT from the Choke coil L. At this time, energy is stored in the choke coil L. Next, when gate signal of IGBT turned OFF, IGBT will be turned OFF and the energy stored in L during the ON time of IGBT will be discharged through the diode D, electrolytic capacitor C, load, primary side and the + side of DB. Assuming the input voltage of PFC Module (voltage between + and - of DB) as Ei, the output voltage (voltage at the both ends of smooth capacitor) as Vo, switching cycle of IGBT as T and ON time of IGBT as ton, the voltage between collector emitter of IGBT Vs will be as follows; Vs= 0 (during ON of IGBT: ton) Vs= Vo (during OFF of IGBT: T-ton) Here, assuming no loss in L and IGBT, average value of Vs turns equal to Ei, Ei = (T-ton)/T x Vo Therefore Vo = T/(T-ton) x Ei As ton is a smaller value than T, output voltage Vo will be higher than input voltage Ei. 2 – 12 AYXPC18LR L DB + D Ei Control IC Vs Vo + RL C IGBT - 29.3. PFC Module Driving Electronics Circuit The PFC Module circuit operates continuously while the compressor is driving. The microcomputer detects output DC voltage of the PFC Module circuit with pin 69, and controls to keep the DC voltage to be the target value. The microcomputer controls so that the input AC current wave form will become a sine wave detecting the input AC voltage of the PFC Module circuit with pin 71 and detecting AC current wave form with pin 72. The microcomputer calculates to do above mentioned controls, and outputs the PFC signal (ON/OFF duty control of 20kHz) from pin 89. The PFC signal is input to IN of PFCM, and the PFC Module circuit operates. 29.4. Output voltage of PFC Module The output DC voltage of the PFC Module circuit changes within the range from 310V to 370V in proportion to the voltage value of the power supply. When the power supply voltage is AC 230V, the output DC voltage is DC 330V. 2 – 13 AYXPC18LR Service Manual CHAPTER 3.

DISASSEMBLING PROCEDURE AYXPC18LR Manual If, in carrying out repairs and modifications, the work requires the use of arc- and flame-producing apparatus, such as welding, brazing and soldering equipment, this work shall only be started after the rooms have been thoroughly ventilated. While the work is being carried out, the mechanical ventilation, if any, shall be kept in constant operation and all windows and doors kept open. In the case of repairs to parts of the refrigerant circuit, it may be necessary that not only the workman but also a second person shall be present for observation and assistance. Necessary protective equipment shall be available and, in the case of open flames or arcs, fire extinguishing apparatus shall be ready to hand. Welding and brazing shall be carried out by qualified workmen. Be sure to disconnect the power cord from the AC power outlet before starting the disassembly procedure. When reassembling the unit after repairing, be sure to install screws to their original positions. The screws used are not the same in specifications such as corrosion-resistant treatment, tip shape and length. After the air conditioner is repaired or parts are replaced, measure insulation resistance of the equipment using an insulation resistance meter. If the measured resistance is lower than 1 MΩ, inspect parts and repair or replace defective parts. [1] INDOOR UNIT CAUTION: DISCONNECT THE UNIT FROM THE POWER SUPPLY BEFORE ANY SERVICING. 1.
