IMPORTANT
The planning of the heat pump system is described in this chapter with the example of Germany,
i.e. some of the legal regulations, planning aids, information sources, parameters, promotion
programmes etc. may apply only to Germany. For planning a heat pump system in other European
countries, the corresponding specications 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 list of individual steps
given below also points to the corresponding sections in which the concrete planning steps are
described:
1. Refrigeration technology and performance criteria (→ 5.1, p. 92)
> Determination of design outside temperature θe and design heat load (→ 5.1.1,
p. 92)
> Determination of the domestic hot water demand (→ 5.1.2, p. 93)
> Determination of the heating surface temperature (→ 5.1.3, p. 94)
> Operating mode and determination of the bivalence point (→ 5.1.4, p. 94)
> Determination of the pipe length correction factor for bi-bloc systems (→ 5.1.5,
p. 95)
> Example: Calculation of the total heating capacity required (→ 5.1.6, p. 95)
> Cooling (→ 5.1.7, p. 96)
2. Installation criteria (→ 5.2, p. 97)
> Acoustics (→ 5.2.1, p. 97)
> Installation of a bi-bloc system (→ 5.2.2, p. 100)
> Installation of a mono-bloc system (→ 5.2.3, p. 109)
3. Hydraulics (→ 5.3, p. 112)
4. Electricals (→ 5.4, p. 116)
5. Heating and cooling capacity depending on supply water temperature and outside
temperature (→ 5.5, p. 128)
6. Application examples (→ 5.6, p. 136)
Planning with Panasonic Aquarea Designer Online Tool
For easy and quick calculation as well as optimisation of heating systems with heat
pump, Panasonic o󰀨ers the Aquarea Designer Online Tool, which is accessible for free on
www.PanasonicProClub.com.
The online tool o󰀨ers 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 seasonal coe󰀩cient of performance
● Cost comparison
● Report download possible
