Ground & Air Source Hybrids

CLAUSIUS aerothermal allows an aerothermal capture but with geothermal heat pumps, which gives rise to simpler and more reliable systems. CLAUSIUS hybrid systems allow the best of geothermal and aerothermal to be obtained in a single system and are, without a doubt, the future of air conditioning systems.

CLAUSIUS Air Source

CLAUSIUS_2021_ES-19

About

CLAUSIUS Air Source unit transfers the energy captured from the outside air to the heat pump through a closed circuit in which glycol is recirculated using the circulation pumps integrated in the heat pumps, the same as in the ground source systems. Therefore, CLAUSIUS Air System is based on a very simple and reliable installation since the circulation of refrigerant between the outside air unit and the heat pump inside de house is not required. Consequently, it does not require the installation by highly qualified personnel and increases the reliability of the system due to it avoids possible leaks of high pressure refrigerant in the pipes. Furthermore, compared to systems with compact air source heat pumps, which components are outdoors exposed to weather elements, and therefore, subject to inclement weather, CLAUSIUS air system has the advantage that only the air unit is on the outside meanwhile all the other components are located inside the house protected from the elements and weather exposure, which, with no doubt, increases considerably its reliability and service life.

Clausius Hybrid System

CLAUSIUS_2021_ES-20

About

CLAUSIUS ground source heat pumps can be used in hybrid geothermal-aerothermal systems, in which both a ground collector and an air collector are used simultaneously and integrated in the same installation. Hybrid systems allow to obtain the advantages of both energy collection systems and avoid their major drawbacks, which are the low efficiency of the air systems at low outside temperatures and the high cost of the ground collectors.

CLAUSIUS heat pumps incorporate a specific control for hybrid systems. The control system choose the operating conditions that provide maximum possible energy efficiency by an optimum glycol flow distribution between the ground and the air collectors, obtaining the maximum efficiency of the heating and cooling system at all times.

Ground Recharging: CLAUSIUS hybrid systems allow to recharge energy in the ground when the outside temperature is high and heating the house is not required, by transferring the heat energy extracted from the air in the air collector to the ground through the ground collector. Recharging the ground is carried out at a very low cost and allows to use it as an energy storage system. The energy stored is subsequently recovered through the ground collector and the heat pump, which allows to reuse it to heat the house through the heating system.

  • The heating and recirculation of the glycol is carried out only inside the Air Unit, thus avoiding its circulation through the connecting circuit between the Air Unit and the heat pump. This feature avoids significant heat losses, as well as the expansion-contraction processes due to the strong temperature changes of the elements and junctions of the circuit during the defrosting proceses, which provides the system a reliability and efficiency much higher than the systems in which the heating of the glycol is carried out in the heat pump.

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.
