coldest climate the BHR system operates more frequently at higher pressure than the B system, with a detriment in its performance as refrigerator. As stated above, when the maximum value of the pHS is reached, the subcooling at the gas cooler is reduced by reducing the fan velocity or bypassing the heat exchanger. Figure 5 shows the comparison in terms of frequency over the year of the gas cooler outlet temperature between the two systems. In climate 1 the 1 2 3 4 5 6 7 89 temperature of carbon dioxide tGC,out exiting the gas cooler is not increased to meet the full heating demand of 10 the supermarket, which is satisfied just by occasionally increasing pHS .

The peak at the minimum temperature is still present because, when the load evaporator is activated to meet the full heating demand, the subcooling is turned back on. Figure 4.
