… kWh/m2year. One of the alternatives to oil burners that were suggested is heat pumps. The two types of heat pumps studied, ground source or air source, were both found to be profitable, although the ground source heat pump would be slightly more profitable. In the calculations …
… gearbox is driven by an air turbine. An auxiliary generator and a hydraulic pump are mounted on the gearbox to provide the aircraft with electrical and hydraulical power. The air?ow to the turbine is regulated by an Air Modulating Valve, AMV. This report describes a new model of …

… efficient measures. The first one dealt with how to install an air/water heat pump to lower a building’s use of energy.This was carried out through simulation. Therefore, a code in MATLAB was written for this purpose, and this model was used to evaluate the potential energy …
… power meter with compact dimensions to allow mounting inside the casing of a pump. It should be able to measure the power, both from a regular power supply and fed from a VFD. The accuracy needs not to be on reference level, but the price/performance-ratio is an important …
