The store has 18 low- and 36 medium- and high-temperature fixtures. There are now 10 such installations in Europe, all circuits operating with subcritical CO2 cycles. There are an additional 10 to 12 stores with CO2 used for low-temperature fixtures and R-404A used for medium- and high-temperature fixtures.
The store's inside ambient temperature is controlled to 69.8 degrees F (21 degrees C) during daytime open hours, and to 64.4 degrees F (18 degrees C) at night. Outdoor ambient temperature ranges during the year from 14 degrees to 86 degrees F. Fresh air ventilation is completely sufficient for cooling during the summer months, and in winter the store is warmed entirely by heat reclaim, although in some other similar installations where winter ambients are low, auxiliary heat must be used because of the CO2 system's high efficiency.
