Understanding Heat Pumps (HPs)

Understanding Heat Pumps (HPs)

A heat pump (HP) is a device that can both heat and cool a space. To heat, it extracts heat from the air, the ground, or the water outside your house, converts the heat to a higher temperature level with the help of electrical energy, and transfers it indoors. For cooling, it extracts heat from the room and releases the resulting waste heat to the surroundings.

There are different types of heat pumps, such as air-air, air-water, geothermal heat pumps, and other types of heat pumps. Each type uses different ambient heat sources. The AI assistant currently supports calculations for air-water heat pumps.

Aim of HP calculation

The calculation will display the expenses (investment and operational)
as well as the size of the heat pump.

The size, or capacity in kW, of a heat pump refers to the amount of heat energy that the heat pump can provide or remove from a space within a certain period. It indicates the heating or cooling capability of the heat pump. A higher kW capacity means that the heat pump can generate more heat or provide more cooling, making it suitable for larger spaces or areas with higher heating or cooling requirements.

Presently, the calculation solely presents the annual operational expenses. A comprehensive ROI calculation, such as comparing it to traditional gas boilers, will be included in future releases.

About HP calculation

Heating load (kWh):

The heating load of a residential building refers to the amount of heat energy required to maintain a comfortable indoor temperature during colder periods. Take a look at the recent gas bills if you own a gas boiler. To calculate the kWh for a gas boiler when consumption data is provided in m³, just multiply the m³ value by 10.

Heated living area (m²):

The "heated living area (m²)" in a home is the heated space for living, including rooms like the living room, bedrooms and kitchen.

Electricity price grid consumption (cent/kWh):

In a country like Germany, household electricity prices can include generation, transmission, distribution costs, taxes, levies, surcharges, and network charges. These factors contribute to the overall cost of electricity consumed from the grid for households.

Renovation status:

The simulation now takes into account whether a single-family residential building categorized as "8" has been renovated or not. These buildings belong to the construction year class between 1984 and 1994 (Tabula database Germany). It serves as an ideal foundation for evaluating your property. Subsequent versions of this module will include additional types of buildings and countries.

Heating distribution system:

The heating distribution system may include either floor heating or radiator heating. In the case of floor heating, the simulation incorporates a supply temperature of 35°C, which is more efficient for heat pump heating. As for radiator heating, a supply temperature of 55°C is used to minimize heat transfer surfaces.

Location:

For the computation, currently the location is configured for Leipzig, Germany; upcoming versions of this module will include additional locations.

Simulation method:

The simulation method is undoubtedly the fundamental aspect of this module. It relies on artificial intelligence capable of assessing every potential scenario specific to this module.

Currently, the calculations encompass hourly occupancy profiles, heating setpoints, and natural ventilation in accordance with DIN EN 16798, DIN V 18599, and DIN EN 15251 for residential buildings. Future iterations of this module will incorporate extra usage patterns.
