(e) Correction of heating capacity in relation to the frost on the outdoor unit heat exchanger
(d) When the outdoor unit is located at a lower height than the indoor unit in cooling operation and when the
outdoor unit is located at a higher height than the indoor unit in heating operation,
the following values
should be subtracted from the values in the above table.
The correction factors will change drastically according to weather conditions. So necessary adjustment should be
made empirically according to the weather data of the particular area.
Note (1) Equivalent piping length can be obtained by calculating as follows.
Equivalent piping length = Real gas piping Number of bends in gas piping
×
Equivalent piping length of bends.
