6 Ho w a heat pum p w orks The heat pump collects heat from the outdoor air The Optima heat pump has been manufactured for easy and reliable use as well as to provide your house with inexpensive and environment friendly heating. The easiest way to describe how a heat pump works is to say it works like a refrigerator , however , the other way round.[...]

7 The route of the refrigerant thr ough the heat pump in heating mode The refrigerant meets the outdoor air in the evaporator (heat exchanger). The air is drawn through the evapora- tor by a fan located on top of the heat pump. The refrigerant, which was previously in a liquid state, will evaporate in this process. The pressur e is low and heat is [...]
