Page 17: Design Features & Information
Comfort STOREMASTER™ Design Features & Information ENERGY SAVING FEATURES Free Cooling The StoreMaster packaged unit has been designed to provide the cooling load required whilst optimising energy efficiency at all times and as such will take advantage of free cooling whenever available. If the free cooling available cannot satisfy the required full cooling load, DX (mechanical) cooling is used to supplement the output. - Page 18 STOREMASTER™ Comfort Design Features & Information ENERGY SAVING FEATURES Electronic Expansion Using an EEV allows for good refrigeration control whilst operating at part load and lower ambient conditions with a reduced condensing pressure. By fitting an Valves (EEV) EEV and adjusting the head pressure control setting an increase in the system EER (Energy Efficiency Ratio) of up to 30% can typically be seen.
