Digital scroll compressors
Greenheck’s Model ERCH, VER energy recovery ventilators gains digital scroll compressors, offering cooling capacity turndown from 10% to 100%.
Greenheck introduced digital scroll compressors in its Model ERCH and Model VER energy recovery ventilators to improve temperature and humidity control and save energy. Featuring an integral controller with a time-averaging sequence, the rate at which the scrolls are engaged and disengaged varies to match the required cooling capacity. Using digital scrolls for capacity control provides leaving air temperatures as precise as 1 F. In addition to precise temperature control, digital scrolls offer cooling capacity turndown from 10% to 100%. The compressor turndown results in longer cycle times that improve humidity control, reduce compressor wear, and eliminate the need for hot gas bypass to improve the overall efficiency of the system.
