Abstract: A method for controlling a vapour compression system (1) comprising a compressor unit (2) comprising one or more compressors (3, 12), a heat rejecting heat exchanger (4), a receiver (6), an expansion device (7) and an evaporator (8) arranged in a refrigerant path. A pressure value indicating a pressure prevailing inside the receiver (6) is obtained, and the obtained pressure value is compared to a first threshold pressure value. In the case that the obtained pressure value is below the first threshold pressure value, the compressor(s) (3, 12) of the compressor unit (2) are controlled in order to reduce a suction pressure of the vapour compression system (1).

Abstract: The invention provides a method of controlling a release of thermal energy in a building. The method comprises steps of defining a control criterion for the building, defining a set of climate variables which influence the release of thermal energy in the building, and defining for each climate variable, a climate signification index which defines the importance of that climate variable for the release of thermal energy in the building. Furthermore, the method comprises a step of receiving a set of predicted future climate variables, and subsequently a step of combining the climate signification indices and the predicted future climate variables to provide control instructions for release of an amount of thermal energy in the building to satisfy the control criterion. The invention further provides a comfort control system.
