Abstract
Thermal stratification in the storage tank is extremely important in order to achieve high thermal performance of a solar heating system. High temperatures in the top of the storage tank and low temperatures in the bottom of the storage tank lead to the best operation conditions for any solar heating system. High temperatures in the top of the storage tank established by the energy from the solar collector reduce the use of auxiliary energy. Low temperatures in the bottom of the storage tank improve the operation conditions for the solar collector. Using thermal stratified heat storages results in longer operation periods and improved utilization of the solar collector. Thermal stratification can be achieved, for example by using inlet stratification devices at all inlets to the storage tank.
This paper presents how thermal stratification is established and utilized by means of inlet stratifiers. A new multi layer fabric stratification pipe is presented together with marketed stratification pipes.
