Benefits of technology

[0004] The object of the present invention is to provide a climate control installation of the initially defined kind, which in comparison with prior art utilizes the components of the climate control installation more effectively for achieving better operating economy and a better utilization of the energy sources used.
[0006] Thanks to the second connection between the first circuit and the second circuit for transferring heat energy between the second circuit and the third medium via the first heat energy transferring member, a more effective utilization of the first heat energy transferring member is enabled.
[0010] Thus, in this way heat energy from the third medium may be absorbed directly by the second circuit for heating purposes without having to use the heat pump. This contributes to a decreased use of the heat pump, which is advantageous for the operating economy of the installation.
[0011] According to a preferred embodiment of the invention the third medium has heat emitting as well as heat storing properties. In this way it is possible to store, in the third medium, a heat energy excess transferred from the second circuit via the first heat energy transferring member. This stored heat energy may then be utilized in different ways. For instance, when there due to changed operating conditions arises a need for use of the heat pump for heating purposes, the stored energy may be transferred via the first heat energy transferring member to the first medium and be reused by the heat pump for heating purposes. This results in that the heat pump needs to add less work for achieving heating compared with the case when no heat energy from the second circuit has been stored previously in the third medium. The heat energy stored in the third medium may, if desired, also be utilized for heating purposes directly without using the heat pump. This is achieved by transferring the heat energy stored in the third medium via the first heat energy transferring member and the first circuit through the second connection to the second circuit.
[0013] Thanks to the provision of the second heat energy transferring member in the first circuit transfer of further heat energy to the first medium in addition to the energy being transferred via the first heat energy transferring member is enabled, which improves the efficiency of the heat pump. Furthermore, existing energy sources are utilized advantageously in that cooling indoor air may contribute in heating, for instance, tap hot water.
[0015] In this way cooling indoor air is possible by means of the third medium, as this is colder than the indoor air. Under advantageous circumstances, for instance during summertime, the need for operation of the heat pump for cooling the indoor air is thereby eliminated.

Problems solved by technology

To include a heat pump with members belonging to the pump for transferring heat energy between different media in a climate control installation is rather costly, and that is why it is of large economic importance to utilize a heat pump included in a climate control installation and equipment associated therewith as effectively as possible.

first embodiment

[0021] In FIG. 1 is very schematically shown a climate control installation according to the invention. The installation includes a heat pump 1, the input side of which being connected to a first circuit 11 containing a first medium. Furthermore, the heat pump 1 is connected, on its output side, to a second circuit 12 containing a second medium. For instance, the circuit 12 contains water and the circuit 11 contains a glycol / water mixture. This is of course only one possible combination and optional other media suitable for the purpose, which are circulatable in the circuits, are useful as well. A conventional circulation pump 1.3 is arranged in the circuit 12 and a conventional circulation pump 14 is arranged in the circuit 11 for circulating the media in the respective circuits.

[0022] The heat pump is adapted to, during circulation of the first medium in the first circuit 11 and the second medium in the second circuit 12, absorb heat energy from the first medium on its input side ...

second embodiment

[0030] In FIG. 2 is schematically illustrated a climate control installation according to the invention. This embodiment is much similar to the embodiment illustrated in FIG. 1, as regards design and function, but has no connection 30 and the possibilities afforded by that Identical components are indicated with identical reference numerals and they will therefor not be described more in detail.

[0031] According to this embodiment the first circuit comprises at least one second member 22, for instance in the form of a suitably adapted heat exchanger, for transferring heat energy between the first medium and indoor air. The second heat energy transferring member 22 is adapted to transfer heat energy from the indoor air to the first medium. Hereby, the heat pump 1 may also be used for cooling indoor air and thus not only for heating indoor air and tap hot water via the system 3. When there is a heating demand present in the system 3 and the heat pump 1 is operated for that reason, cons...

The first circuit comprises at least one first member (21) for transferring heat energy between the first medium and a third medium. The installation comprises a second connection (30) between the first circuit (11) and the second circuit (12) for transferring heat energy between the second circuit (12) and the third medium via the first heat energy transferring member (21).

Description

FIELD OF THE INVENTION AND PRIOR ART [0001] The present invention is related to a climate control installation according to the preamble of the appended independent claims. [0002] For heating premises and buildings and tap hot water climate control installations comprising a heating boiler operating with fossil fuels have been used for a long time. It is also known to include in climate control installations a heat pump complementary to the heating boiler in order to decrease the use of fossil fuels. In the latter type of heat installations mainly the heat pump is utilized during the summer for meeting the present heating demand, whereas the heating boiler meets a major part of the heating demand during the winter, the heat pump contributing to the heating to a less extent than during the summer. [0003] To include a heat pump with members belonging to the pump for transferring heat energy between different media in a climate control installation is rather costly, and that is why it ...
