Abstract

Provided is a broadband heat pump system including: a heat pump module including a plurality of heat pumps that supply hot water with different levels of temperature; a heat source supply module that introduces a heat source from one heat source or selectively introduces a heat source from one or a plurality of heat sources among heat sources with different levels of temperature so as to produce a heat source with a desired temperature; and a controller that controls the heat pump module and the heat source supply module to select one from the plurality of heat pumps to be appropriate to a temperature of hot water requested by a demand source and to receive a heat source with a necessary temperature from the heat source supply module so that the selected heat pump is able to supply hot water with the requested temperature.

First claim

The invention claimed is:

1. A heat pump system comprising:
a plurality of heat sources with different levels of temperature;
a heat pump module comprising a plurality of heat pumps that supply hot water with different levels of temperature, wherein each heat pump receives only a heat source with a fixed temperature and the fixed temperatures of the heat sources received at the plurality of heat pumps are different from each other;
a heat source supply module comprising a plurality of heat source mixers that receive the heat source from at least one of the plurality of heat sources, wherein each heat source mixer produces only the heat source with the fixed temperature dedicated to each heat pump and the fixed temperatures of the heat sources produced at the plurality of heat source mixers are different from each other, wherein each heat source mixer is connected to only one of the heat pumps to supply the dedicated heat source with the fixed temperature and is not connected to remaining heat pumps, and each heat pump is connected to only one of the heat source mixers to receive the dedicated heat source with the fixed temperature and is not connected to remaining heat source mixer;
a hot water mixing module with different levels of temperature and comprising a plurality of hot water mixers that allow hot water to be selectively introduced from at least one of the plurality of heat pumps and mix the introduced hot water, wherein each hot water mixer is connected to each heat pump which is connected to a single heat source mixer among the plurality of heat source mixers and mixes the introduced hot water, wherein each hot water mixer is connected to a single demand source among a plurality of demand sources and supplies the mixed water to the connected single demand source; and
a controller that controls the heat pump module, the heat source supply module, and the hot water mixing module to select one hot water mixer and one heat source mixer from the plurality of hot water mixtures and the plurality of heat source mixers, to select one or a plurality of heat pumps among the plurality of heat pumps corresponding to the selected hot water mixer and to select one or a plurality of heat sources among the plurality of heat sources corresponding to the selected heat source mixer to be appropriate to a temperature of hot water requested by a demand source among the plurality of demand sources so that the selected hot water mixer, the selected heat source mixer, the selected heat pump, and the selected heat source are able to supply temperature controlled hot water to the demand source.

2. The heat pump system of claim 1 , wherein the plurality of heat pumps comprise a first heat pump, a second heat pump, and a third heat pump as temperature levels increase.

3. The heat pump system of claim 2 , wherein the plurality of demand sources comprise a low-temperature demand source, a medium-temperature demand source, and a high-temperature demand source,
the hot water mixers comprise a low-temperature hot water mixer, a medium-temperature hot water mixer, and a high-temperature hot water mixer, and
the heat source mixers comprise a low-temperature heat source mixer, a medium-temperature heat source mixer, and a high-temperature heat source mixer.

4. The heat pump system of claim 1 , wherein the heat source supply module selects the heat source in consideration of at least one from among substantial temperature levels, levels of heat flow, and provision time zones of the plurality of heat sources.

5. The heat pump system of claim 3 , wherein the low-temperature heat source mixer supplies a low-temperature heat source only to the first heat pump,
the medium-temperature heat source mixer supplies a medium-temperature heat source only to the second heat pump, and
the high-temperature heat source mixer supplies a high-temperature heat source only to the third heat pump.

6. The heat pump system of claim 1 , wherein the plurality of heat pumps simultaneously receive the heat sources with the different fixed temperatures, respectively.

7. The heat pump system of claim 1 , wherein the plurality of heat source mixers simultaneously produce the heat sources with the different fixed temperatures, respectively.
