An exhaust air heat pump basically an energy recycling system. It collects energy from warm inside air as it leaves your home via the ventilation system and reuses it to heat up fresh incoming air and tap water.
If you’re building a new house or developing new apartments, now’s the perfect time to take advantage of NIBE’s energy efficient heating technology. Install an exhaust air heat pump and you can enjoy a healthy, oxygen rich atmosphere inside your home, at the same time as reducing your electricity consumption by more than 50%.
It’s amazing, but true. We know because we’ve been using heat pump technology in Sweden for over 30 years. What’s more, exhaust air heat pumps have been more or less mandatory in all Swedish houses built since 1980’s, due to changes in Swedish building regulations, which is why NIBE’s developers have has plenty of time to refine the technique!
A heat pump is an electrical device that extracts heat from one place and transfers it to another. The heat pump is not a new technology; it has been used in Sweden and around the world for decades. Refrigerators and air conditioners are both common examples of heat pumps.
Heat pumps transfer heat by circulating a substance called a refrigerant through a cycle of alternating evaporation and condensation (see Figure 1). A compressor pumps the refrigerant between two heat exchangers. In one heat exchanger, the evaporator, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings. The refrigerant is then compressed en route to the heat exchanger, the condenser, where it condenses at high pressure. At this point, it releases the heat it absorbed earlier in the cycle.
Information about air filters can be found in your “Installation and Maintenance Instructions” for the product. New filters can be ordered from NIBE if the filter needs changing.
Here you can find a dockningsschema which describes the above case.
It is slightly up to the individual, but it is recommended to take the air from bathroom, kitchen (not kitchen fan), hall, utility room etc. The supply air to the house is often through grilles under the windows or in the walls and these are placed in other rooms where one does not extract any air. Through this one obtains a natural flow and exchange of air throughout the house.
