COMPACT COLLECTOR FOR BRINE TO WATER HEAT PUMP A FIELD TEST
Due to the possibility of optimisation of the horizontal brine collector, a special compact collector for the brine to water heat pumps was developed. Field tests and simulation regarding the efficiency and the energy gain have been made over 2 years. The results of the field measurement and the simulation show a high efficiency of this system. The compact collector is an area saving way of reducing the digging work for the brine collector and reduces the needed area for the collector in comparison to a standard horizontal collector. Both simulation and measurements prove that there is enough capacity to recover the brine source in summer. The minimum temperatures that occur at the end of the heating period do not pass the -2.5 °C.
