Abstract: A transcritical vapour compression system (1) and a method of controlling a transcritical vapour compression system (1) are disclosed. The vapour compression system (1) is of the booster type, and comprises an external heat exchanger (19) arranged downstream relative to a refrigerant outlet of the gas cooler (3), said external heat exchanger (19) being arranged to cool refrigerant leaving the gas cooler (3) by means of heat exchange with an external heat sink, e.g. comprising energy piles (21) arranged under ground. The method comprises the step of allowing refrigerant leaving the gas cooler (3) to pass through the external heat exchanger (19), thereby cooling the refrigerant leaving the gas cooler (3) by means of heat exchange with an external heat sink. An energy efficient system is obtained which can be used in hot climate, where the ambient temperature is above the triple point of carbon dioxide (C0 2 ).
