Description
技术领域technical field
本实用新型涉及可再生能源利用技术，特别涉及一种太阳源的蓄能型非电燃气机热泵冷热电联供系统。The utility model relates to renewable energy utilization technology, in particular to a solar source energy storage type non-electric gas engine heat pump combined cooling, heating and power supply system.
背景技术Background technique
在能源问题日益突出的今天，建筑节能问题得到了越来越多的重视。太阳能是一种取之不尽、用之不竭的可再生能源，并且无污染，因而受到了人们的广泛关注。太阳源热、电捕捉转换系统是将光伏和光热结合在一起，既有电力的输出又有热能输出，可实现较高的太阳能利用率。但是，由于太阳能热流密度较低，易受季节和天气的影响，尤其在阴雨天和夜晚。此时，若单独使用太阳能为建筑供暖并不能满足建筑对能源的需求，此时往往使用电加热辅助，大大增加了建筑的能耗。Today, with the increasingly prominent energy problems, more and more attention has been paid to the issue of building energy conservation. Solar energy is an inexhaustible, inexhaustible renewable energy, and non-polluting, so it has received widespread attention. The solar heat source and electricity capture conversion system combines photovoltaic and photothermal energy, which has both power output and heat energy output, and can achieve a high solar energy utilization rate. However, due to the low heat flux density of solar energy, it is easily affected by seasons and weather, especially in rainy days and nights. At this time, if using solar energy alone to heat the building cannot meet the energy demand of the building, electric heating is often used to assist at this time, which greatly increases the energy consumption of the building.
燃气机热泵是通过内燃机燃烧天然气驱动压缩机工作，具有高效、节能、安全、环保、稳定等优点。在能源与环境问题突出的今天燃气机热泵越来越受到重视。但是当燃气机热泵在寒冷地区供暖时，蒸发温度降低，大大降低了燃气机热泵的效率。The gas engine heat pump works by burning natural gas through the internal combustion engine to drive the compressor, which has the advantages of high efficiency, energy saving, safety, environmental protection, and stability. Gas engine heat pumps are getting more and more attention today when energy and environmental issues are prominent. However, when the gas engine heat pump is heating in a cold area, the evaporation temperature is lowered, which greatly reduces the efficiency of the gas engine heat pump.
