  • CHUNLAN FRD23, Typical case analysis - 109 - Chapter XIII Typical case analysis Case I: A user installed a number of FR125/S air duct type air conditioners and complained about poor heating effect. Pressure measurement showed that indoor unit and outdoor unit systems were normal without clogging or leakage, and indoor area and thermal insulation met requirements. Analysis: (1) The indoor unit was installed in ceiling layer of toilet with ventilating windows. Fresh air leaked into return air so that indoor unit return air temperature in winter was lower than 0℃; (2) Insulation on air delivery hose and static pressure box was merel

  • CHUNLAN FRD23, Maintenance - 94 - Chapter XI Maintenance ● To place the unit in outage, first stop the air conditioner and then turn off power switch. ● After long operation of outdoor unit, dust will accumulate on surface of heat exchanger, lowering heat transfer efficiency and hence unit performance. Use long hair brush or compressor air to clean such surface. ● Cleaning cycle of indoor strainer depends on installation position and environment. Frequently clean indoor strainer to avoid failure. Indoor units of FR(D)95, FR(D)125/S, FR(D)180/S, FR(D)260/S, FR95-C and FR125-C/S are complete with strainer. Indoor units of o
