The refrigerant evaporation temperature can fall below 0 ° C. Thus, in brine systems with groundwater we
recommend using an intercooler to prevent freezing problems and evaporator fouling.
Inside the heat pump are included the following components required for the brine system (see section ).
•
Variable speed and high efficiency pump (energy class A).
•
Expansion vessel (5 l).
•
Safety valve (6 bar).
•
Drain valve.
To connect the brine circuit piping, take into account the note in
Figure 5.5
and the following
recommendations.
•
Use the flexible hoses that come with the heat pump to avoid excessive stress in the inlet and outlet
pipes.
•
Install shut-off valves on the brine outlet and inlet circuits, these should be as close to the heat pump
as possible, to facilitate future maintenance work.
•
Install the components necessary to carry out the filling / emptying in the return pipe.
•
Install a particle filter in the return line. We recommend installing valves just before and after the filter
to avoid losing antifreeze mixture during cleaning or filter replacement.
•
Install air vents at all points of the installation where air pockets may form.
•
Thermally insulate the pipes of the brine circuit to avoid condensation problems.
