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
1
The minimum/maximum frequency limitation
A
While refrigerating:
is the maximum operation frequency of the
compressor;
IN
is the minimum operation frequency of the compressor.
B While heating:
is the maximum operation frequency of the compressor;
IN
is the minimum operation frequency of the compressor.
1
The frequency limitation which is affected by the environment temperature.
Heating mode:
