The floor heating system of phase change energy storage (FHSPC), performing well in storing and releasing thermal energy, plays a significant role in using solar energy and low-priced nocturnal electrical power for heating. However, due to such problems as ineffective package and insufficient overall integration of phase change material, research of FHSPC has not made progress in practical application. This paper researches thermal storage effect of a new floor heating system of phase change energy storage using solar hot water as the heat source and double layers of capillary network as the heat dissipation end. Differential scanning calorimeter was used to choose capric acid as the main energy storage material. For a steady heating cycle of heating for 8 hours and releasing for 16 hours, acceptable thermal condition is observed in the test room. The new FHSPC could provide long span intermittent heating with little heat loss, therefore the intermittent energy source can be well utilized

Floor Heating

An optimized heat pump control for building heating was developed for minimizing CO 2 emissions from related electrical power generation. The control is using weather and CO 2 emission forecasts as inputs to a Model Predictive Control (MPC)—a multivariate control algorithm using a dynamic process model, constraints and a cost function to be minimized. In a simulation study, the control was applied using weather and power grid conditions during a full-year period in 2017–2018 for the power bidding zone DK2 (East, Denmark). Two scenarios were studied; one with a family house and one with an office building. The buildings were dimensioned based on standards and building codes/regulations. The main results are measured as the CO 2 emission savings relative to a classical thermostatic control. Note that this only measures the gain achieved using the MPC control, that is, the energy flexibility, not the absolute savings. The results show that around 16% of savings could have been achieved during the period in well-insulated new buildings with floor heating. Further, a sensitivity analysis was carried out to evaluate the effect of various building properties, for example, level of insulation and thermal capacity. Danish building codes from 1977 and forward were used as benchmarks for insulation levels. It was shown that both insulation and thermal mass influence the achievable flexibility savings, especially for floor heating. Buildings that comply with building codes later than 1979 could provide flexibility emission savings of around 10%, while buildings that comply with earlier codes provided savings in the range of 0–5% depending on the heating system and thermal mass.
