The Building Heating Design Method by Combining the Analysis on the Energy Consumption of Photovoltaic-Assisted Air Source Heat Pumps
With the popularization of the centralized winter heating in northern regions by the country,the environmental pollution and energy consumption caused by coal combustion heating have become more serious.In order to optimize the energy consumption of heating systems in northern buildings,a photovoltaic-assisted air source heat pump heating system was studied and designed.The research method constructed a building energy consumption model through numerical simulation,optimized the air source heat pump heating system based on heating demand,and added insulation layers and defrosting modes.At the same time,the study evaluated the heat load of the building heating system and corrected the actual efficiency of the heat pump with the least squares method.And the energy consumption of the air source heat pump was coordinated by using photovoltaic power supply,and the heating control system was optimized based on the overall efficiency of the heating system.The research results show that the average heating capacity of photovoltaic-assisted air source heat pumps can reach 23.74 kW,and the overall energy-saving benefits in simulated environments are 77.19%-83.26%,which is 59.24%higher than that of the traditional boiler heating.It can be seen that improving the heating system can achieve higher energy-saving benefits under the same heating effect.Therefore,improving heating design has a more efficient energy-saving effect,and provides an environmentally-friendly and energy-saving heating method for building heating.
