Abstract

A heat pump system comprises: a compression device 12, a heat rejecting heat exchanger 14, an expansion device 18 and a heat absorbing heat exchanger 16; wherein the expansion device 18 provides a controllable degree of expansion. The heat pump system is operated in accordance with a method comprising: determining a temperature indicative of frosting conditions on an exterior surface of the heat absorbing heat exchanger 16; operating the heat pump system in a first mode if the temperature indicative of frosting conditions is above a threshold value, and operating the heat pump system in a second mode if the temperature indicative of frosting conditions is within a range of temperatures that is below the threshold value, wherein in the second mode the heat pump system is arranged to adjust the degree of expansion at the expansion device 18 to increase the superheat at the outlet of the heat absorbing heat exchanger 16 compared to the superheat when operating in the first mode to thereby increase an external temperature of the heat absorbing heat exchanger.
