Frequently Asked Questions
What is the model number and associated codes?
The Condensing Unit Model is OP-LPQM026AJ with Compressor CAJ2446Z (Electrical code G).
How are the sound spectrum data calculated?
They are calculated by adding the full speed sound power levels of the compressor and fan motor, following EN13215 conditions.
What is the typical Sound Power Spectrum at 10 meters?
The 1/1 Octave dBA value at 10 meters ranges from 61 dB to 38 dB across various frequency bands (e.g., L=55, 250Hz=63).
What factors are considered when evaluating sound power?
The evaluation considers the effect of noise reduction due to enclosure and insulation because the compressor and fan motor are placed in a packaged unit.
