Domestic air conditioner
7. Functions and control
7.1 Main functions and control specification
7.1.1 The operation frequency of outdoor unit and its control
7.1.1.1 The operation frequency control of compressor
The operation frequency scope of compressor
:
Mode
Minimun operation frequency
Maximun operation frequency
Heating 36Hz
90
Hz
Refrigeration 36Hz
80
Hz
7.1.1.2 The starting of compressor
When the compressor is started for the first time, it must be kept under the conditions of
58Hz,88Hz for one minute (the overheating protection of the outdoor unit air-blowing temperature,
immediately decrease the frequency when the compressor is overflowing and releasing the pressure)
,
then it can be operated towards the target frequency. When the machine runs normally, there’s no
such process. After starting the compressor for operation, the compressor should run according to the
calculated frequency, and every determined frequency for protection should be prior to the calculated
frequency.
7.1.1.3 The speeds of increasing or decreasing the frequency of the compressor
The speed of increasing or decreasing the frequency rapidly 1 -----------1HZ/second
The speed of increasing or decreasing the frequency slowly 2 -----------1HZ/10seconds
7.1.1.4 The calculation of the compressor’s frequency

)
The minimum/maximum frequency limitation
A
.
While refrigerating: F-MAX-r is the maximum operation frequency of the compressor; F-MIN-r is the
minimum operation frequency of the compressor.
B
.
While heating: F-MAX-d is the maximum operation frequency of the compressor; F-MIN-d is the
minimum operation frequency of the compressor.

Remarks: The above are the maximum frequency limitations of the complete appliance which are
affected by the environment, and they have nothing to do with the ability of the indoor unit.
