Air source heat pumps and their role in the Swedish energy system

摘要: Newly produced air source heat pumps can provide energy from outdoor at temperature as low -20°C. As a result they could be utilized during most days of the year even in cold Nordic climates. The drawback is reduction efficiency become colder, resulting lower supply times when it needed. Despite its inverse relationship between and temperature, were installed 57000 detached houses Sweden 2010 alone, which 3% total stock. That makes sold heating technology for 2010, 1.6 more than number installations ground pump 3 connections to district same year. Similar trends found other countries.This study compares use an with existing commercial technologies analyzes impacts on primary use, final electricity production costs benefits house owners. It was that converting electric heated Swedish detaches biomass based CHP or bed-rock reduce resources, benefit society. Converting pellets stove power demand level out load curve. would utilities secure supply. However cost effectiveness one important drivers owners choose measures. For reason may likely by installation air-source pumps.
