Note:
1. These data are based on the following conditions:
Evaporator Air Input Temperature 85°F DB, 66 °F WB.
Condenser Air Input Temperature 115°F DB.
2. The starting current is indicated for each compressor motor.
3. The maximum currents of the compressor can be estimated as follows.
Max. current
Max. instantaneous current
Max. IPT×: Compressor power input from the performance table at the expected maximum condition
STC, IPT, RNC: Compressor data from the above table
4. The data in the compressor motor column shall indicate the respective values of the refrigeration cycle. 他
the voltage imbalance is to be <2% between phases.
