Protection Control 13.1 Restart Control (Time Delay Safety Control) • • • When the thermo-off temperature (temperature which compressor stops to operate) is reach during:o Cooling operation – the compressor stops for 3 minutes (minimum) before resume operation. o Soft Dry operation – the compressor stops for 6 minutes (minimum) before resume operation. If the operation is stopped by the remote control, the compressor will not turn on within 3 minutes from the moment operation stop, although the unit is turn on again within the period. This phenomenon is to balance the pressure inside the refrigerant cycle. 13.2 7 Minutes Time Save Control • • The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between the compressor ON temperature (A) and compressor OFF temperature (B) during the period. This phenomenon is to reduce the built up humidity inside a room. 13.3 60 Seconds Forced Operation • • Once the air conditioner is turned on, the compressor will not stop within 60 seconds in a normal operation although the intake air temperature has reached the thermo-off temperature. However, forced stop by pressing the OFF/ON operation button at the remote control is permitted. The reason for the compressor to force operate at the minimum 60 seconds is to allow the refrigerant oil run in a full cycle and return back to the outdoor unit. 13.4 Starting Current Control • • When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start to operate at 1.6 seconds later. The reason of the difference is to reduce the starting current flow. 49 13.5 Freeze Prevention Control • • To protect indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid form return to compressor. This control will activate when temperature of indoor heat exchanger falls below 2°C continuously for more than 4 minutes and compressor turn off. Indoor Heat Exchanger Temperature (°C) 10 Recovery 4 min 2 Compressor OFF • • Compressor will restart again when the indoor heat exchanger temperature rises to 10°C (Recovery). Restart control (Time Delay Safety Control) will be applied in this control if the recovery time is too short. 13.6 Compressor Reverse Rotation Protection Control • • If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and indoor heat exchanger is 2.5°C or less for continuously 2 minutes, compressor will stop and restart automatically. Time Delay Safety Control is activated before the compressor restart. Compressor starts for ≥ 5 minutes ▲T ≤ 2.5°C for 2 minutes Compressor OFF Compressor restart ▲ T = Intake air temperature – Indoor heat exchanger temperature • • • This is to prevent compressor from rotate reversely when there is an instantaneous power failure.

Troubleshooting Guide 15.1 Refrigeration cycle system In order to diagnose malfunctions, ensure the air conditioner is free from electrical problems before inspecting the refrigeration cycle. Such problems include insufficient insulation, problem with the power source, malfunction of a compressor and a fan. The normal outlet air temperature and pressure of the refrigeration cycle depends on various conditions, the standard values for them are shown in the table to the right. Different in the intake and outlet air temperatures Normal Pressure and Outlet Air Temperature (Standard) Outlet air Gas Pressure Temperature Mpa 2 (°C) (kg/cm G) Cooling Mode 0.4 ~ 0.6 (4 ~ 6) 12 ~ 16 Condition: Indoor fan speed = High Outdoor temperature = 35°C Normal • Measuring the air temperature different • Measuring electric current during operation • Measuring gas side pressure More than 8°C (15 minutes after an operation is started) Less than 8°C at the cooling mode Value of electric current during operation Higher than specified Dusty condenser preventing heat radiation Excessive amount of refrigerant Lower than specified Gas side pressure Cooling Mode High Low Low Inefficient compressor Insufficient refrigerant Clogged strainer or capillary cube 53 15.1.1 Relationship between the condition of the air conditioner and pressure and electric current Condition of the air conditioner Cooling Mode Low Pressure High Pressure Electric current during operation Insufficient refrigerant (gas leakage) Ô Ô Ô Clogged capillary tube or strainer Ô Ô Ô Short circuit in the indoor unit Ô Ô Ô Heat radiation deficiency of the outdoor unit Ò Ò Ò Inefficient compression Ò Ô Ô • Carry out the measurement of pressure, electric current, and temperature fifteen minutes after an operation is started. 15.1.2 Diagnosis methods of a malfunction of a compressor Nature of fault Symptom • Electric current during operation becomes approximately 20% lower than the normal value. Insufficient compressing of a compressor • The discharge tube of the compressor becomes abnormally hot (normally 70°C to 90°C). • The different between high pressure and low pressure becomes almost zero. Locked compressor • Electric current reaches a high level abnormally, and the value exceeds the limit of an ammeter. In some cases, a breaker turns off. • The compressor has a humming sound. 54 16.
