The work to be performed provides for replacement of a central steam system which will entail the removal of steam equipment at each facility and the installation of high efficiency systems such as natural gas fired hot water appliances, high efficiency heat pumps and hot water equipment to meet heating load requirements.
It seems likely that Swedish GSHP systems tend to switch to electrical resistance heating under peak heating load conditions at the same time as national electricity consumption peaks, requiring import of power with higher C[O.
The lowest outdoor temperatures reached during the heating season are used for the calculation of heating load of conventional building.
The Shoebox Heat Pump which was launched into the market place earlier this month, is a small, extremely quiet, MCS-accredited and British-made ground source heat pump specifically designed to provide both space heating and domestic hot water in new build and retrofit properties where the peak heating load is no greater than 3.
The recovered heat is then available for the absorption chiller and/or the heating load.
Within these meshes, a dynamic hydraulic adaption towards homogenous mass flow allocation is achieved by positioning the valve ranges in each storey according to the current heating load via installed valve drivers.
Specific topics include: fundamentals of heat transfer and thermodynamics, internal heat gain, heating load calculations, solar radiation and heat gain, treatment of thermal bridges, and treatment of uncontrolled spaces.
While moving slowly through them, air can exchange heat with the mass of the earth under the building, being cooled in summer and warmed above zero in winter to lessen the heating load.
