Heat Sources

The principle behind a heat pump is quite simple: A heat pump extracts heat from a lower-temperature external heat source (the ground or the air) and then uses drive energy to emit that heat at a higher temperature in the form of useful heat. GeoT*SOL basic supports the following heat pump configurations:

Brine/Water
Brine/water heat pumps with ground probes extract heat stored in lower ground layers. This requires a hole drilled vertically into the ground, which can be performed in a very small space. Depending on the customer's heat requirement, one or several probes are used.

Air/Water
Air/water heat pumps suck outside air through special channels and extract the heat contained therein. This heat is transferred to the water-operated heating system.

 

System Types

With GeoT*SOL basic you can simulate five different heat pump system types, from simple to very complex, each for the configuration of brine/water and air/water.

 

Climate Data Generator MeteoSyn

The climate database from MeteoSyn contains global data records. You can select the relevant location on an interactive map or you can select the locations from a list. New climate data can also be created by interpolation of existing climate data. In addition, it is possible to load other climate data in wbv format.

 

Simulation

The dynamic minute-step simulation over the course of the year gives you the following parameters for the selected heat pump system:

  • The Annual Coefficient of Performance (ACOP) according to EN 15316-4-2 and (for comparison purposes) ACOP according to VDI directive 4650.
  • Where appropriate the solar fraction, i.e. the amount of collector energy relative to the sum of generated energy.
  • The annual required electrical energy addition for the heat pump, auxiliary energy consumers (pumps, fans), and supplemental heating.
  • The amount of energy generated by the heat pump and (when appropriate) the solar collector circuit, on an annual basis.
  • The annual useful heating energy and energy for domestic hot water.

 

Economic Efficiency Calculation

The economic efficiency is an important argument for property owners. It is determined by way of the heat price by allocating investment costs (minus subsidy) and operating and maintenance costs (including anticipated increases in electricity costs) to the generated heat energy over appropriate periods (service life, interest on capital). You can then use the heat price to compare the heat pump to other heating systems, such as gas or oil-fired boilers.

 

Results

All results are documented in a project report that you can save and forward to your customer as a PDF or RTF file or print and deliver together with proposal documents. The report contains:

  • Page 1: Cover sheet with desired project data, such as logo and your firm's contact data.
  • Page 2: System schematic and results of the annual simulation (energies, ACOP, and heat price).
  • Page 3: Specifications and system components.
  • Page 4: The heat pump's monthly coefficients of performance and power consumption over the course of the year.
  • Page 5: Specifications for model calculation.
