High power range models have the following options:




In CLASSIC and ELITE configurations and in all H and HC models, we can integrate a passive cooling production system. The passive cooling system consists of one heat exchanger and its corresponding 3-way valves in both brine and heating circuits.
In all models, activation and control of passive cooling production is carried out by the heat pump itself. In models HC PC, it is possible to select between different options, only passive cooling production, only active cooling production, or both. In case of using both systems (passive and active cooling), the heat pump always decides the optimal production system, giving priority to passive cooling.

A desuperheater can be integrated in all STRONG and STRONG DOUBLE models. The integration of the desuperheater allows the production of DHW at high temperature, as well as the simultaneous production of heating and DHW or swimming pool and cooling with DHW in the HC DS models.

The desuperheater can be used in a separate circuit only for the production of DHW or high temperature heating, or in combination with the heating circuit, in such a way that by means of the corresponding combination of valves, both condenser and evaporator can used in parallel for the production of DHW and heating or cooling, or in series using the condenser and desuperheater simultaneously for the production of DHW or heating.

The control system of the STRONG and STRONG DOUBLE models allows controlling both the circulating pumps of the desuperheater and condenser circuits, as well as the solenoid valves that allow the condenser and desuperheater configurations in series or parallel.

Models with an integrated desuperheater, in addition to allow the simultaneous production of DHW and heating or cooling, when condenser and desuperheater are used in series, cause an increase in the efficiency of the heat pump.

10 Benefits of the heat pumps powered by renewables:


1. Reduced Carbon Emissions:

ERV and HRV systems provide a continuous supply of fresh outdoor air while expelling stale indoor air. This helps maintain a healthier indoor environment by reducing the concentration of pollutants, odors, and contaminants.

2. Energy Efficiency:

Heat pumps are inherently efficient because they move heat rather than generate it through combustion. When combined with renewable energy, their efficiency is further enhanced, as the energy input comes from sources with high energy conversion efficiency.

How heat pumps work with various renewable energy sources?

Heat pumps can be powered by renewable energy sources such as solar, wind, and geothermal energy to provide efficient heating and cooling. When renewable energy is used to operate heat pumps, the overall system becomes more environmentally friendly and sustainable.

1. Solar-Powered Heat Pumps:

  • Solar energy is captured using photovoltaic (PV) panels, which convert sunlight into electricity.
  • This electricity is used to power the heat pump's compressor and other components.
  • The heat pump uses the electricity to drive the refrigeration cycle, transferring heat from a low-temperature area (e.g., outdoor air or ground) to a high-temperature area (indoors or hot water storage).

3. Wind-Powered Heat Pumps:

  • Wind turbines generate electricity from the kinetic energy of the wind.
  • The generated electricity is used to operate the heat pump, following the same process as solar energy process. The heat pump transfers heat as needed, either for space heating or cooling and domestic hot water.

5. Geothermal-Powered Heat Pumps:

  • Geothermal energy is derived from the Earth's natural heat, available underground.
  • A ground source heat pump (GSHP) is used to extract heat from the ground and transfer it to a building.
  • GSHPs can work in both heating and cooling modes by exchanging heat with the ground through a loop system.
  • Renewable electricity may still be required to power the heat pump's compressor and other components, enhancing the overall efficiency of the system.
