Aquarea air / water heat pump – design handbook 07 / 2014
Heat pump system
Systematics and overview
Overview
The Aquarea heat pump models are configured so that a suitable model
is available for all typical applications. All models are listed with their
properties and functions in the table at the beginning of the Design
Handbook.
As shown in the overview tables the available systems differ externally,
especially between the monobloc systems and bi-bloc systems, and the
units are equipped with one or two fans depending on the rated power.
Series
Aquarea LT
Aquarea T-CAP
Aquarea HT
The Aquarea series differ through their maximum supply water
temperature and capacity stability at very low outside temperatures
as follows:
Maximum supply water temperature:
55 °C
Capacity at very low outside temperatures: kW heating capacity varies
Maximum supply water temperature:
55 °C
Capacity at very low outside temperatures: Heating capacity is
constant up to -15 °C
at 35 °C output water
temperature
Maximum supply water temperature:
65 °C
Capacity at very low outside temperatures: Heating capacity is
constant up to -15 °C
at 35 °C output water
temperature
Heating capacity and coefficient of performance (COP) of the Aquarea LT Aquarea T-CAP
and Aquarea HT series with 12 kW at different outside temperatures and a supply water
temperature of 35 ˚C and a return water temperature of 30 ˚C.
