PASSIVE COOLING IN CLASSIC & ELITE

gama-1

About

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.

BUILT-IN DESUPERHEATER IN CLASSIC MODELS

gama-2

About

In CLASSIC configuration and in all H and HC models, a system with desuperheater can be integrated.
The system with desuperheater allows the production of DHW at high temperature as well as a simultaneous production of heating and DHW or swimming pool and cooling with DHW or swimming pool in HC DS models. The desuperheater system consists of one heat exchanger (desuperheater), a circulation pump and the corresponding valves and control system. Our desuperheater system allows:

Simultaneous production of heating and DHW at high temperature.
Simultaneous production of cooling and DHW at high temperature.
Simultaneous production of heating and swimming pool.
Simultaneous production of cooling and swimming pool.
Production of only DHW using the condenser and desuperheater simultaneously, which increases the efficiency of the heat pump in these processes

About

In CLASSIC configuration, all H and HC models can be combined with a DHW tank with desuperheater to produce DHW at high temperature. Combination of CLASSIC models with DHW tank with desuperheater allows DHW production at temperatures up to 80 ºC without electric heaters.
CLASSIC models combined with DHW tanks with desuperheater include all connection and control elements of the DHW production system and are supplied preloaded with refrigerant and with quick connections. The capacities of CLAUSIUS DHW tanks with desuperheater available are 250, 300 and 500 liters. The use of these tanks enables to considerably increase the amount of DHW available. The use of a 500 liters tank with DHW at 80 ºC would allow to obtain more than 1000 liters of DHW for domestic use at 38 ºC.

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.
