摘要： Heat pump system (100) comprising a heat medium circuit (210,220,230,240,250,310,320,410,420,430,440,450,460) in turn comprising at least three heat exchanging means (314,315,315,422,433,452) between the heat medium and a respective heat source or sink selected from outdoor air, a water body, the ground, indoor air, pool water or tap water, a valve means (311,312,313,421,431,451) arranged to selectively direct the heat medium to at least two of said heat exchanging means, and a control means (500). The invention is characterized in that the heat pump system comprises temperature sensors (314a,314b;315a,315b;316a,316b;423,424,425;432,434,435) both upstream and downstream of at least one of said heat exchanging means, in that the system determines, based upon temperature measurement values comprising at least one value read from said sensors, to what heat exchanging means the heat medium is to be directed, and in that when heat medium is not directed to a certain heat exchanging means a measured temperature value is read upstream and downstream of the certain heat exchanging means, and in that an alert is set off in case the values differ by more than a predetermined value. The invention also relates to a method.

摘要： Heat pump system (100) comprising at least one heat medium circuit (210,220,230,240,250,310,320,410,420,430,440,450,460) in turn comprising a compressor (211), an expansion valve (232,242), at least two different primary heat sources or sinks selected from outdoor air, a water body, the ground or exhaust air, at least one of two different secondary heat sources or sinks selected from indoors air, pool water and tap water, a respective temperature sensor (412,432) at each of said primary heat sources or sinks, a valve means (421,431,451) for selectively directing the primary-side heat medium to at least one of said primary heat exchanging means, and a control means (500). The invention is characterised in that, in a secondary-side heating operating mode, the temperature of said primary heat sources or sinksis measured, and in that the primary-side heat medium is directed only to the primary heat exchanging means associated with the heat sources or sinks with the highest temperature. The invention also relates to a method.

The invention is characterised in that, in a secondary-side heating operating mode, the temperature of said primary heat sources or sinks is measured, and in that the primary-side heat medium is directed only to available primary heat exchanging means associated with the heat sources or sinks with the highest temperature. The invention also relates to a method.

摘要： Heat pump system comprising a heat medium circuit (210, 220, 230, 240, 250, 310, 320, 410, 420, 430, 440, 450, 460) in turn comprising a compressor (211), an expansion valve (232, 242), at least one primary heat exchanging means (422, 433, 452) between a primary-side heat medium and a respective primary heat source or sink selected from outdoor air, a water body or the ground, at least one secondary heat exchanging means (314, 315, 316) between a secondary-side heat medium and a respective secondary heat source or sink selected from indoors air, pool water and tap water, and a control means (500). The invention is characterised in that the speed of the compressor can be controlled, in that an opening of the expansion valve is adjustable, in that the speed of the compressor is controlled, and in that an output temperature of heat medium flowing out from the expansion valve is controlled by controlling the opening of the expansion valve given the controlled speed of the compressor. The invention also relates to a method.
