REMKO MWL series
Energetic result in the overall system view
Every heat pump works particularly efficiently if the target temperatures/water temperatures are set as low as
possible.
The source heat pump in the first stage generates an ideal source temperature of 20 °C for the MWP 35
water/water heat pump module in the second stage.
If we now look at the entire system, each heat pump works extremely effectively and in the optimum energy
range for itself.
Due to the source temperature of 20 °C, no radiation losses occur at normal room temperatures. This pre-
vents overheating of shafts and passageways. In addition, heat losses are reduced to almost zero.
With this system a diaphragm expansion vessel [8] in the source circle (primary circle) is used and thus the
complete system the primary circuit and the secondary circuit (heating cycles downstream of MWL 35) is
protects. The diaphragm expansion vessel must then be dimensioned accordingly.
