The ideal solution for heating a modern home. Atlantic Alfea heat pumps are a joint project of Atlantic and Fujitsu, combining Atlantic’s experience in heating technology with Fujitsu’s expertise in cooling and air-conditioning technology. The result is AIR-TO-WATER heat pumps with continuously controlled output and highly efficient heat energy extraction, designed for the low-temperature systems of modern new builds.
Alfea heat pumps consist of two parts:
- Inverter outdoor unit (evaporator, variable-speed fan, compressor with continuously controlled output and expansion valve)
- An indoor hydraulic unit containing a tank with a coaxial heat exchanger, the heat pump’s control system and weather-compensated control of the heating circuit.
Heat pumps use renewable energy from the surrounding environment. Solar energy stored in the air is converted, with the help of electricity, into heat for heating. Alfea heat pumps are so efficient that they can be used all year round as the sole heat source for almost all modern buildings. Outdoor air can be used as a source of thermal energy down to -25 °C. For existing buildings with higher heat losses, bear in mind that as the air temperature drops, the heat pump’s heating output also falls significantly. For such buildings, an additional heat source therefore needs to be included in the heating system.
Protecting the air plays an important role today – especially reducing CO2 emissions and treating fossil fuels sparingly. These arguments make the case for using renewable energy as widely as possible. A heat pump consumes a considerable amount of electricity to drive its compressor, and that electricity is not always generated in a fully environmentally friendly way. A heat pump can therefore be considered an alternative heat source only in part, and its real benefit to the environment depends directly on how it is controlled and on its resulting electricity consumption.
Advantages of ALFEA:
- Long service life
The patented Alfea exchanger combines two key advantages in one: a large-surface coaxial copper exchanger housed in a stainless steel buffer tank. Compared with a conventional plate exchanger, the coaxial exchanger is more resistant to fouling. The copper used transfers heat very well, and both the outer and inner surfaces of the exchanger are textured with a raster pattern to enlarge the heat-exchange area. The buffer tank plays an essential role in the evaporator defrosting process. The constant 16-litre reserve of heating water is also useful for hydraulically balancing conditions on both the heat generation and consumption sides, even though the Alfea modulates its output and precisely follows the demands of the heating system. (the advantages of the patented exchanger are a 16-litre stainless steel buffer tank with a coaxial counter-flow copper exchanger, large-diameter tube plates with a large heat-exchange area, low hydraulic resistance, and the fact that there is no risk of the exchanger fouling)
- Wide operating range
Thanks to inverter technology and refrigerant injection, a wide operating range is guaranteed. In winter, it can provide heating and hot water deep below freezing, down to an outdoor temperature of -25 °C. In summer, on the other hand, you can enjoy the heat pump’s benefits up to an outdoor temperature of +35 °C. Alongside hot water heating, it also offers a more effective cooling function.
- High efficiency
Among the heating systems available on the market, the heat pump is the most environmentally friendly source of heat energy. Its high efficiency is guaranteed by state-of-the-art technology for extracting low-temperature energy from the outdoor air – inverter technology – and precise control of the refrigerant circuit.
