Problems solved by technology

Therefore, the heat pump must also be switched off in order not to be damaged, resulting in a reduction in overall system efficiency
Moreover, repeated switching on and off increases the wear and tear on the heat pump

Embodiment Construction

[0011] The heat pump 1 comprises two sides, a warm side and a cold side. On either side, a first heat exchanger 2 and a second heat exchanger 3 are respectively arranged. The heat pump 1 is of the liquid-liquid type, meaning that the heat pump 1 is arranged to transfer thermal energy between two liquid heat carriers.

[0012] According to a preferred embodiment, the heat pump 1 is reversible, meaning that the heat pump 1 can be used for both heating and cooling. Depending on the mode of operation selected, either side may be the cold side. During heating operation, the first heat exchanger 2 side is the cold side and the second heat exchanger 3 side is the warm side, and the opposite way during cooling operation.

[0013] In other words, the heat pump 1 is arranged so as to be able to transfer thermal energy from the side of the first heat exchanger 2 to the side of the second heat exchanger 3 and also vice versa. For such a heat pump, it is preferred that the first heat ex...

Abstract

Device for heating and cooling, respectively, comprising a heat pump (1), a first heat exchanger (2) arranged at a first side of the heat pump (1), which first heat exchanger (2) is thermally connected to a first heat carrier being circulated in a first loop (10), and a second heat exchanger (3) arranged at a second side of the heat pump (1), which second heat exchanger (3) is arranged to transfer thermal energy to or from a second heat carrier which is circulated in a second loop (20). The invention is characterised in that the first (10) and the second (20) loops are interconnected by a conduit (4) so that the first loop (10), the second loop (20) and the conduit (4) together form a connected system, in which connected system one and the same heat carrier is arranged.

Description

technical field [0001] The invention relates to a device for separate heating and cooling. More specifically, the invention relates to such a device comprising a heat pump. Background technique [0002] Heat pumps are often used for heating and / or cooling. This heat pump has two sides, a warm side and a cold side. In so-called reversible heat pumps, these two sides can be changed so that the warm side becomes the cold side and vice versa. This is useful if the heat pump is to be operated at different times for heating and cooling. [0003] In a closed system, a cooling medium flows between two sides in such a heat pump. Each side is thermally connected via a respective heat exchanger to an outer loop through which the heat carrier flows. The term "heat carrier" is used herein for a liquid that is capable of transferring thermal energy from one location to another when the liquid is transported between the two locations. In other words, heat carriers can carry heat or c...
