Panasonic Aquarea B1 Planning And Installation Manual page 16

Product Description
The heat pump is operated by using the wired remote controller, which is placed in the building
and is linked to the compact device with a max. 15 meter long cable.
CAUTION
Danger of water pipes freezing in outside temperatures below 0 °C
If the heating circuit in the compact system is filled with water and the outside temperature falls
below 0 °C, the risk exists in the compact system that the water pipes may freeze. This can
cause a lot of damage to the device.
The client should therefore ensure the absence of frost by taking one of the following
measures:
► Operate the heating circuit using a food-safe antifreeze mixture (propylene glycol).
► Provide an additional cabinet heating in the compact device, to prevent the heating
circuit from freezing up.
► Empty the heating circuit by using a built-in device (manually or automatically) before
freezing starts.
4.5.2 Series
The Aquarea heat pump system has three different series that are in turn available in multiple
model variants. This is intended to offer the best possible solution to address individual heat
supply and air-conditioning requirements for buildings using Aquarea heat pumps.

In all, the following features occur in various combinations:
● "Heating and cooling" or "Heating only"
● Nominal heating power (3, 5, 7, 9, 12 or 16 kW)
● Power E-heating element heat pump (3, 6 or 9 kW)
● Electrical connection (single phase or three phase)
With the large number of different model variants, which is an expression of the large variety of
characteristics and functions of the Aquarea heat pumps, Panasonic can achieve a high level of
flexibility and adaptability for the most varied applications. Seen from outside, the devices look
almost the same except for the notable differences as in compact and split systems or combina-
tion hydro-module and can therefore be described together in respect of many planning-relevant
properties. The relevant differences, even those between different product generations, will be
pointed out at the appropriate point.
The Aquarea heat pump models are configured in terms of their properties such that a suitable
model is available for all typical applications. All model variants are listed with their character-
istic properties and functions are listed in the model overview at the beginning of this manual
(→ 1 Model range, p.
As the overview table shows, the available models differ in their appearance mainly in the com-
pact system and split system, where the devices are fitted with one or two fans, depending on
the nominal power.
The Aquarea series are distinguished by their maximum water inflow temperature and perfor-
mance stability at very low outside temperatures as follows:

The illustration below shows the thermal output and COP of the Aquarea series LT, T-CAP and HT
with 12 kW for different outside temperatures and a water inflow or return temperature of 35 °C or
30 °C.
