We install Danfoss Air Source heat pumps.
These systems provide superb efficiency as well as a significant reduction on your energy costs. Energy is stored around your home. It is a source that is constantly replenished by the heat of the sun. With an air heat pump you neither need to dig or drill. Instead, you retrieve the energy directly from the surrounding air using an air module. The heat pump is located indoors or outdoors, depending on which model you choose.
Advantages
- Lower investment costs
- No drilling needed
- No impact on the ground
How it Works
- Brine* circulates in a collector coil and absorbs the heat energy from bedrock, ground, air or water.
- At the heat exchanger (evaporator) the tepid brine in the collector coil meets the ice-cold refrigerant** in the heat pump, which is then heated a few degrees and condenses.
- Then, a compressor compresses the now gaseous refrigerant. When the pressure exceeds the temperature rises. The heat that is then generated is transferred via a heat exchanger (condenser) to to your home’s heating system.
- Via a condenser, the refrigerant releases the heat to the heating system of your home. In connection with this the refrigerant is cooled.
- The refrigerant circulates and an expansion valve lowers the pressure and the refrigerant becomes cold again. The process begins again when the refrigerant meets the tepid brine from the collector coil.
- Heat pumps are built around the fact that gas that is compressed gets hot, and gas that expands cools. Remember a bicycle pump that compresses air, creating heat.
* The brine is a mixture that cannot freeze, for example glycol.
** Modern environmentally sound refrigerant are used, e.g. hydrocarbons and carbon dioxide.
