The correct selection of the heating system is an important decision that will have an impact for many years. With an air source heat pump you can heat cost-effectively, especially in new buildings and where low heating flow temperatures are used.
Inverter technology - instantly and on demand
Enhanced vapour injection - boosts power at low outdoor temperaturs (down to -22°C)
Intelligent and powerful control unit
Heating, cooling and domestic hot water production
SOLARFOCUS engineers designed the air source heat pump vampair to work optimiced in different climat conditions. Long term testing in the in-house climat chamber and large field test were made to cope with all different climats around Europe. The production of vampair is in the factory in Steyr/Austria.
An air source heat pump which is designed and equipped with the inverter technology is modulating the heat output wright on demand. So if the ambient air temperature changes the heat demand of the building changes as well. This changes heat demand leads to an adapted heat output of the vampair due to modulating the fan speed and copressor speed. With the inverter technology you get precise power adjustment for every season in the year and therefore a highly cost effective operation of your equipment. One additional side effect of this technology is that it provides as well a dramandouse noise reduction to owner and neighbours. Disturbing and expensive start-stops are reduced to its minimum or completely avoided. This level of comforr is not possible to get with any other established technology.
Enhanced vapour injection increases the efficiency, while the power requirement is reduced at the same time. Thus higher flow temperatures and higher heating output (especially at low ambient temperatures) are possible for the same unit size. Furthermore, the compression temperature is reduced, increasing the life of the compressor.
An efficient heat pump can be recognised in high performance figures even at low outside temperatures. For example the vampair reaches at an outside temperature of 2°C a coeffidient of performance (COP) of 4.37. Even at -7°C the heat pump reaches a COP of 3.51 with heating water flow temperatures of 35°C.
One of the biggest advantages and what you can recognise easily as unexperienced end-user is the difference in noise levels of air source heat pumps. Depending on used components there are hugh differences between air source heat pump models. The vampairis one of the most silent models avialable on the market. This difference is based in the measures taken in order to avoid or minimise enpleasant air noise and turbulances.
The vampair has the following equipment for lowest noise emissions:
All these measures lead to an absolute silent and pleasant air source heat pump.
The air source heat pump comes with a smart-grid interface. With the aid of smart-grid function the vampair will be able in the electrical grid of the future to use cheap renewable excess current out of over production.
The decisive factors to minimise unpleasent noise or air turbulances:
The radial-axial desing is the best of two worlds. On the one hand to achieve a straight air flow and on the other hand a high efficient preassure rise. All that with lowest noise emissions.
Through the extraordinary geometry almost no air-, performance- or deflection-loss occures at the fan.
The EC-technoloy (electronically commutated motor) guarantees highest efficiencies.
The fin evaporator consists of a high quality aluminium-copper heat exchanger with hydrophilic coating and a generous designed fin spacing.
The hydrophilic coating leads to a fast discharge of condensed water drops and to a better heat transfer from air to refrigerant. Hence the heat exchanger needs much more time to ice up. No coating whould lead to a much faster ice up of the heat exchanger.
The time between two defrosting cycles is therefore much longer and the air source heat pump can operate longer in the optimised point. The amount of undesirable defrosting cycles is so kept on its minimum.
It is in the nature of things that a fan produces a certain noise level. But even the best and quietest fans can be made even quieter by appropriate measures. One of these measures is the use of soundproofing fins. A welcome side effect is improved protection against driving rain. The fins also permit hardly any water to penetrate into the housing of the heat pump.
Rotating movement around its own axis is only very rarely found in nature. Visible fan rotation is considered to be bothersome. A screen of soundproofing fins helps.
