Air source heat pump

Air source heat pump

A heat pump that relies on outside air as the heat source and heat sink; not as effective in cold climates as ground source heat pumps.

The Hybrid features a unique combination of the Vortex condensing oil boiler with the green advantages of an Aerona3 air source heat pump which is designed to maximise overall efficiency with the use of an advanced control system.
1 Most people opt for either a ground or air source heat pump because water source heat pumps need a lake, river, stream or other body of water to work, and most of us don't have one of those in our garden.

While manufacturers gives performance data without frosting and there are no explained and standardized way of including frost formation and decrease of seasonal performance factor due to defrosting periods, we used empirical data driven frost formation model which helps to create better fit simulation model which more accurately reflects air source heat pump operation under frosting temperatures.

The results show that the heat pump electricity consumption was reduced by 20.2%, from 6421 kWh to 5114 kWh, when combining PV/T systems with an air source heat pump. The considered system has five PV/T systems connected in series, with (d = 51 mm [d = 2 in.]), and row mass flow rate of 0.1 kg/s (0.22 lb/s).
According to the Energy Saving Trust, fitting an air source heat pump costs around pounds 6,000 to pounds 10,000.
(1,2) Air source heat pump efficiency ratings are given in heating seasonal performance factor (HSPF) and are typically in the range of 7.7 (Standard 90.1) to 8.5 (Standard 189.1).
Green credentials include photovoltaic roof panels to generate electricity from daylight, an air source heat pump to generate heating, and a water catchment system.
Included in the sustainable technologies is a two-stage variable capacity air source heat pump in House A.
Typically the water from a ground or air source heat pump is only around 50*C, however because the heat is constantly being renewed, the cast iron radiator need only be around 30% larger than if using a conventional boiler with a delta T of 60*C.
It is also testing a new air source heat pump system at a small housing complex in Tipton, Sandwell, to establish how it compares with storage heaters.
