减少我国冬季采暖所造成的大气污染,降低供暖系统的能耗,节约能源一直是建筑节能追求的目标。目前太阳能光伏发电已经成为人类利用太阳能的最主要方式之一,地源热泵已被作为一项旨在解决建筑冷热源问题的新技术,日渐受到人们的重视。将光伏转换与热泵循环有机结合在一起,从而形成了太阳能光伏-地源热泵系统。该系统提高了光电转换和光热吸收效率,光电/光热综合利用,极大地提高了单位面积太阳辐照的利用效率,同时可提高热泵系统在寒冷地区运行的适用性;利用光电效应把太阳能中高能带区域的光能直接转化成电能,可大大提高太阳能的可用能效率;在增加能量储存装置和逆变器的条件下,可以使系统脱离公用电网运行,从而增加了系统的适用性和灵活性;与普通的空气源热泵相比,太阳能地源热泵具有较高的热性能,具有一机多用的功效;与建筑物相结合的太阳能热泵系统,可以增加建筑物的隔热效果,起到减少建筑物冷暖负荷的作用,同时可极大地减少环境污染。
Reduce the air pollution caused by the winter heating in our country, reduce the energy consumption of the heating system, energy conservation has been the goal of building energy efficiency. At present, solar photovoltaic power generation has become one of the most important ways for mankind to use solar energy. Ground source heat pump has been regarded as a new technology to solve the problem of building cold and heat sources, and has drawn more and more attention. The photovoltaic conversion and heat pump cycle organic combination, thus forming a solar photovoltaic - ground source heat pump system. The system improves the photoelectric conversion and light-heat absorption efficiency, photoelectric / light and heat utilization, greatly improves the utilization efficiency of solar radiation per unit area, and can improve the applicability of the heat pump system in cold areas; and utilizes the photoelectric effect to convert solar energy The light energy in the middle and high energy band area can be directly converted into electric energy, which can greatly increase the available energy efficiency of the solar energy. Under the condition of increasing the energy storage device and the inverter, the system can be separated from the utility grid to increase the applicability of the system and Flexibility; compared with the ordinary air source heat pump, solar energy ground source heat pump has high thermal performance, with a multi-purpose machine; combined with the building of solar heat pump system can increase the insulation effect of the building, from the To reduce the cooling load of the role of the building at the same time can greatly reduce environmental pollution.
