A villa of solar powered heat pump application to the project and thermoeconomic analysis

Solar energy has an important place today as it did in the past. As a country, it is necessary to develop sustainable policies in the field of energy and to maintain these policies, to reduce fossil fuel consumptionand at the same time to popülarize energy efficiency activities, and to implement green building designs in residences. Many different systems have been used for space heating and cooling from past to present. Today, emissions due to climate change The search for less heating and cooling systems is increasing day by day. The heating and cooling needs in residences are now met by renewable energy sources. If we consider the developments and advantages in heat pump technology, we see that heat pump systems are more preferred. In this study, the under floor heating of a two-storey villa located in Batman province with a PV (Fotovoltaik) panel integrated heat pump was examined and the changes in performance and emission evaluations were compared if heating with under floor heating with natural gas was preferred. Heating using a solar energy supported heat pump in a villa located in the climatic conditions of Batman province. Cooling and domestic hot water needs were met. In this study; For there quired heat loss calculation, cooling calculation and boiler capacity calculation, heat loss calculation, cooling load calculation and boiler capacity calculation were made by entering the values of the building components used in the villa with the Heating Solutions Navigator program developed by Daikin company. In calculations made with natural gas; Based on heat loss, a natural gas combi boiler was chosen for the under floor heating and required capacity needs in the villa. As a result of the selection, the changes in performance and emission evaluations were compared with the heat pump. PV syst program was used for PV (Fotovoltaik) panel design and calculation. Thanks to this program, panel placement on the roof was designed according to panel sizes, taking into account the required roof area and Daily electricity consumption in the villa. Reducing the fossil fuel consumption of the villa and the use of renewable energy sources in the villa were taken into consideration. In the design, the evaporator and condenser temperatures of the heat pump system were selected as -25°C and 55°C, respectively, R32 refrigerant was used in the system and the SCOP (Seasonal Coefficient of Performance) value of the heat pump was 3.76. has been calculated. With 83 solar panels integrated into the heat pump system through out the heating and cooling season, the need for heating and cooling was solved without paying electricity and natural gas bills. The months of January, February, March, April, October, November and December were chosen as the heating season of the villa, and the energy required to obtain hot water and meet the heating needs was found to be 8281.3 kWh, and natural gas was saved with 83 solar panels installed on the roof. Thanks to PV (Fotovoltaik) panels, it was found that an average of 7532,86 TL was saved annually during the heating season. Thanks to the designed system, annual CO2 emissions have been reduced by 801 kg and we have solved heating and cooling entirely with renewable energy. Although the initial investment cost of the heat pump under floor heating system is high, it is seen that the price difference can be covered by the decrease in operating costs. As a result, although the investment costs of heat pumps are higher compared to natural gas, they are clean and reliable and appear to be an advantageous heating system, especially with under floorheating.
