Cooling Potential of Solar-Ice Systems in Multi-Family Buildings
Abstract
Solar-ice systems are an emerging technology to provide renewable heat. Storing the ice that is generated dur-ing the heating season until summer can help to cover the increasing cooling demand in residential buildings. The potential of this approach is analyzed based on dynamic yearly system simulations in TRNSYS. Two dif-ferent control strategies are discussed for three different locations in Switzerland. The results demonstrate that a passive cooling approach can provide cooling that is sufficient for a well insulated multi-family building in Zurich with little additional costs. To increase the cooling potential of the system, the heat pump operation for domestic hot water preparation can be used during the summer months.
