Research And Design Of Solar Energy And Air Source Hot Water Heat Pump System Key Technology

With the gradual increase in the development of the global economy and the level of productivity,the traditional fossil energy consumption dramatically,triggered a worldwide energy crisis and the increasingly serious problem of environmental pollution,in total energy consumption,building energy consumption accounted for a large proportion,therefore,the development and utilization of renewable energy and comprehensive utilization of renewable energy is the main way to solve the energy crisis.Solar energy is the most basic of all kinds of renewable energy,can be transformed and utilized directly,and universal,innocuous,long,huge reserves and other advantages,but in the use of solar photovoltaic power generation system of the existing problems of low efficiency of energy conversion.Heat pump is a kind of low grade heat energy can obtain from the nature of the air,water or soil,the power to do work,high grade heat energy can be transformed into people use technology.Air source heat pump due to the advantages of simple equipment,convenient installation and is widely used,but the performance of air source heat pump has the problems of the outdoor environment of great influence,so the solar energy technology and heat pump combined with solar energy as low heat source heat pump,renewable energy composite use,can improve the performance of heat pump system,and can reduce the the temperature of the solar photovoltaic system,improve the efficiency of power generation,power supply,can also achieve the annual winter heating and summer cooling and heating water and building a variety of required functions.
