Benefits of technology
[0005]Hence, it is the object of the present invention to provide a heating installation and a method for controlling a heating installation as described in the introductory part which enables both to prevent severe temperature drops in e.g. rooms to be heated and provide sufficient heating to e.g. hot water in a hot water container at the same time being as efficient as possible.
Problems solved by technology
In case the priority is set to the domestic hot water production, there is a possibility that the indoor temperature is dropping below the level of comfort.
In case the priority is set to the space room heating, there may occur discomfort in the domestic hot water production if an insufficient hot water production takes place.

[0021]The present application will be described in the following as being implemented in an installation which is capable of heating and cooling a predetermined space (room) and heating water in a hot water container, the water via piping 50 being used for sanitary purposes like the tabs 52, the shower 51, etc. (see FIG. 1). Yet it is to be understood that the present invention may also be implemented in other installation than the one shown in FIGS. 1 and 2, where appropriate.
[0022]The installation shown in FIG. 1 consists of three major components, an outdoor unit 10, an indoor unit 20 and a hot water container 30. The outdoor unit 10 is connected to a piping 11, 12 which connects the outdoor unit 10 to the indoor unit 20. The outdoor unit 10 comprises an inlet / outlet 12 and an outlet / inlet 11 for a refrigerant piping. The indoor unit 20 comprises an inlet / outlet 24 and an outlet / inlet 23 for the refrigerant piping. In addition, the indoor unit has an outlet 21 and an inlet 22 fo...

A heating installation includes a heat pump, heating fluid piping passing through a condenser of the heat pump to exchange heat between refrigerant and heating fluid, first and second objects heated by the heating fluid to first and second set temperatures, a valve switchable between first and second positions to supply heating fluid to the first and second objects, sensors detecting first and second actual temperatures at the first and second objects, and a control. The heat pump also has an evaporator, a compressor and an expansion device. The control in a demand dependent mode, is configured to determine a first demand based on the first set and actual temperatures and a second demand based on the second set and actual temperatures, and is configured to switch the valve to the first and second positions based on comparison of the first and second demands. A method for controlling a heating installation heats the first or second object based on such a comparison.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This U.S. National stage application claims priority under 35 U.S.C. §119(a) to European Patent Application No. 08005301.0, filed in Europe on Mar. 20, 2008, the entire contents of which are hereby incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to a heating installation and a method for controlling the heating installation. It is, however, to be understood that the present invention may also be incorporated in combined heating and cooling installations and is then implemented for controlling the installation in the heating mode. More particularly, the present invention relates to a heating installation comprising a heat pump, particularly an air-source heat pump, having an outdoor evaporator, a compressor, a condenser and an expansion means connected by a refrigerant piping in a cycle; a heating fluid piping passing through the condenser for exchanging a heat between the refrigerant and the heating flu...
