The present disclosure relates to a vapour-compression circuit for circulating a working fluid. The vapour-compression circuit comprises a compressor, a first heat exchanger, an expansion device, a second heat exchanger, a discharge line, a bypass line and a controller. The discharge line extends from an outlet of the compressor to an inlet of the first heat exchanger. The vapour-compression circuit is configured to operate in a heating mode in which the first heat exchanger operates as a condenser and the second heat exchanger operates as an evaporator. The vapour-compression circuit is also configured to operate in a defrost mode in which the working fluid is directed from the compressor to the second heat exchanger via the bypass line and the expansion device, the bypass line extending from the discharge line to bypass the first heat exchanger.
