TOTAL PRESSURE DROP OF THE HEAT PUMP
11.2. TOTAL PRESSURE DROP (H-HL)
Standard NRL heat pump unit (H - HL).
The pressure drops include:
− EVAPORATORS
− WATER FILTERS
− HYDRAULIC CIRCUITS
The diagram pressure drops are
related to an average water
temperature of 10 °C. The following
table shows the correction to apply
to the pressure drops when the
average water temperature varies
The chiller consists of two hydraulic
circuits per module.
The pressure drops indicated in the
graphics are relative to a single
circuit since the hydraulic parallel is in
charge of the customer or the or the
person in charge.
NB:
The water outlet probe (WOP) with its
trap is free, near the electrical box,
remember to insert it in the collector
of the outlet hydraulic parallel, using
a sleeve of ½ inch.
