Productbeschrijving | 2
2.5.1 Schema van het koudemiddelcircuit
Afb. 1 Werkingsprincipe van het koelmiddelcircuit in de warmtepomp
[1] Verdamper
[2] Compressor
[3] Condensor
[4] Expansieventiel
2.6 Binnenunit
De binnenunit is bedoeld om de uit de warmtepompbuitenunit ODU Split
komende warmte over de cv-installatie en de boiler te verdelen. De circu-
latiepomp in de binnenunit is toerentalgeregeld, zodat het toerental bij
geringe vraag automatische wordt verminderd. Daardoor daalt het ener-
gieverbruik.
Wanneer de warmtevraag bij lagere buitentemperaturen hoger is, kan
een externe warmtebron nodig zijn. Externe warmtebronnen kunnen via
de bedieningsunit in de binnenunit worden in- of uitgeschakeld.
IDU Split B
Wanneer de buitenunit met de binnenunit IDU Split B wordt gecombi-
neerd en via de warmtepomp ook warm water moet worden gegene-
reerd, dan moet een externe boiler worden aangesloten. Het
omschakelen tussen centrale verwarming en warm water wordt dan met
een externe 3-wegklep gerealiseerd. De module beschikt over een meng-
module. Deze regelt de warmte van de externe bijverwarming, die afhan-
kelijk van de vraag door de binnenunit wordt gestart.
