– HEAT PUMP
1. IDEA OF ACTION
The principle of the heat pump is to collect heat from the so-called low-temperature lower source (-20°C to
+35°C) and transfer the heat to the high-temperature upper source (CH and/or DHW system). This process is
carried out with electricity supplied to the compressor drive. In systems with a heat pump, it is possible to use
both the hot side (upper source), e.g. for heating purposes, and the cold side (lower source - air), e.g. for air
conditioning or refrigeration.
In the heat pump settings, we can select the following modes of operation:
•
Plant – central heating,
•
DHW – domestic hot water,
•
Plant + DHW - central h domestic hot water.
