为降低碳排放,利用太阳能集热器与空气源热泵联合干燥代替传统的燃煤热风炉干燥。通过对比太阳能热泵联合干燥和热泵单独干燥试验,研究太阳能热泵系统除湿特性。同时,进行太阳能空气集热器辅助空气源热泵的枸杞干燥试验,验证其可行性。在相同干燥温度设定下,太阳能热泵联合干燥相比热泵单独干燥节电了28.8%,高干燥负荷试验组较中等干燥负荷试验组相比节电15%。与传统热风炉烘干房干燥相比,每吨枸杞干燥节约成本448元,同时节约标准煤121.14 kg,可减少CO2排放量317.39 kg。
Abstract
In order to reduce carbon emissions, the combination of solar collector and air source heat pump is used to replace the traditional coal burning hot blast stove drying. The dehumidification characteristics of solar heat pump system were studied by comparing the combined drying of solar heat pump and the drying of heat pump alone. At the same time, the drying experiment of Chinese wolfberry with solar air collector assisted air source heat pump was carried out to verify its feasibility. Under the same drying temperature setting, the solar heat pump combination dryingcan save 28.8% electricity power compared with the heat pump alone drying, and the high drying load experimental group can save 15% electricity power compared with the medium drying load experimental group. Compared with the traditional hot blast oven drying room drying, each ton of wolfberry drying cost is saved 448 yuan, that means saving standard coal 121.14 kg, reducing CO2 emissions 317.39 kg.
