Emerson Climate Technologies Inc. has announced the release of a new eBook to provide helpful information to HVAC contractors and facility managers on the value and impact of compressor modulation. The publication is titled “Understanding Compressor Modulation in Air Conditioning Applications.”
The function of an oil reservoir, commonly known as an oil trap, is to prevent large oil slugs from forming. This is accomplished by trapping a small amount of oil in the reservoir or trap and gradually returning it to the compressor.
For maximum efficiency, a bank of compressors should be connected to evaporators operating at similar temperatures. From an operational standpoint, cases of different evaporating temperatures can be connected to the rack; however, this causes a substantial energy loss.
If hydrofluorocarbons (HFCs) are to have long-term viability, the low-global warming potential (GWP) versions will have to separate themselves from high-GWP types. And the survivors will have to play their part in energy efficiencies, especially in commercial buildings.
