The new KFR-45LW floor-standing air conditioner has poor cooling effect.
Beijing Xinke Air Conditioner Repair Phone provides analysis data.
Analysis and Maintenance: When the machine was turned on, the outdoor temperature was 30℃. The operating current was detected to be 8.4A, which is significantly higher than the rated current. The low-pressure pressure of the system was measured at 0.56MPa, which is slightly high. A preliminary suspicion of a system blockage arose. During operation, while checking the system piping (with reference to Beijing Xinke Air Conditioner Repair Phone), no areas with severe frosting or condensation were found. However, it was noticed that the pressure gauge needle was vibrating violently. Based on experience, this indicated that there was likely air in the system. After re-evacuating the system and refilling with refrigerant, the unit operated normally upon startup.
