18 How does it work? Flow Return Expansion valve Condenser Injection line ( wet gas) Liquid line (liquid process medium) Heating output Compressor Inlet line (gaseous process medium/refrigerant) Pressure line (hot gas) Electrical energy Evaporator Environmental heat

19 What makes it efficient? The rule is: For every °C higher flow rate temperature we have to invest around 3% higher running cost! Source: Internet Temperature difference source/ heating system in °K Leistungszahl= COP COP in relation to the temp. Diff.

In warmer regions the factor will be smaller because of more energy that you will get from the ground even in wintertime. In colder once it has to be bigger.
