IMPORTANT
The planning of the heat pump system is described in this chapter with the example of Germa-
ny, i.e. some of the legal provisions, planning aids, information sources, parameters, promotion
programmes etc. may apply only to Germany, For planning a heat pump system in other Euro-
pean countries, the corresponding specifications and information sources must be determined
and taken into account when planning.
Planning steps
There are multiple steps involved in planning the heat pump system. The listing of the individ-
ual steps given below also points to the corresponding sections in which the concrete planning
steps are described:
1. Cooling technique and performance criteria
> Establishment of standard outside temperature θe and standard heating load
(→ 5.1.1, p. 79)
> Establishment of the hot water requirement
> Establishment of the heating surface temperature
> Operating mode and establishment of the bivalence point
> Establishment of the line correction factor for split systems
> Example: Calculation of the total heat performance required
> Cooling (→ 5.1.7, p. 86)
2. Installation criteria (→ 5.2, p.
> Acoustics (→ 5.2.1, p. 87)
> Installation of a split system
> Installation of a Compact system
3. Hydraulics (→ 5.3, p. 100)
4. Electricals (→ 5.4, p. 105)
5. Heating and cooling capacities depending on water flow and outside temperature
(→ 5.5, p. 116)
6. Examples of use (→ 5.6, p.
Planning with Panasonic Aquarea Designer
For easy and quick calculation as well as optimisation of heating systems with heat pump,
Panasonic offers the Aquarea Designer as a free download from www.PanasonicProClub.com.
The programme offers the following functions:
● Design of the heat pump based on the building and consumption data
● Design calculation based on the integrated climate and weather database
● Quick selection of the suitable heat pump
● Calculation of the Bivalence point
● Calculation of the system consumption number and the annual performance
number
● Cost comparison
● Quick Design or Expert Design as well as short report and long report possible

5.1 Cooling technique and performance criteria
5.1.1 Establishment of standard outside temperature and standard
heating load
The heating load of a building is determined according to DIN EN 12831 ""Heating Systems
in Buildings - Method for calculating the standard heating load" and the possible valid national
appendices and is seen in the planning documents for new buildings. The standard heating load
is calculated for the standard outside temperature θe. The standard outside temperature is the
lowest two-day average of the outside temperature, which has been reached or fallen below 10
times in 20 years. The standard outside temperature is therefore suitable as the design point for
the heat pump.
Example of Germany: Determination of the outside temperature θe according to DIN EN
12831 Annexure 1
