Our factory reported the following;
1) The reason why pre-heat is necessary
• Compressor pre-heat function is equipped to MXY series in order to prevent liquid refrigerant accumulation in compressor that causes damage to compressors.
• Pre-heat function improve the reliability of compressors and contribute to reduce the defect caused to compressor. (some may impact long term energy performance also).
2) Pre-heat pattern and power consumption
• Pre-heat is switched “ON” for 20 min and “OFF” for 40 min in an hour when ambient temp is over 21 degree.
• Average standby-power is 20w (when pre-heat is “OFF”) and 80w (when pre-heat is “ON”)
• Of course stand-by power is not applicable during operation.
update of the mitsubishi high standby power issue.
