52℃, the

compressor and the fan motor keep their original states;

the compressor runs at the normal operating frequency, and the outdoor fan

motor returns to its original state,

5.2.When the operation frequency F≥40HZ, if the temperature of the outdoor

coiled pipe T

outdoor coil≥

57℃, decrease the operation frequency of the compressor by 2Hz，then examine the temperature of the outdoor coiled pipe at 10-second intervals, if T
