| 摘 要： | 针对地源热泵式沼气池加温系统需要打地埋井及铺设地埋管受地质水质局限等问题,系统构建了太阳能—沼液余热式热泵高温厌氧发酵加温系统.对系统发酵池热负荷、沼液余热回收率、中高温热泵机组、太阳能集热装置等关键参数进行了理论计算,得出系统能够保证发酵池温度50±2℃,沼液余热回收量可以达到系统总需要热量的70%.系统特点在于采用太阳能和沼液余热联合作为中高温热泵低位热源并确立其三种运行模式,包括太阳能直接加温模式,太阳能低位热源—热泵加热模式和太阳能—沼液余热回收联合式热泵加温模式. |

| Abstract: | Waste heat recovery coupled with solar assisted heat pump heating system for biogas digester canceled d buried wells, reducing the system initial investment and getting rid of the limitations of ground-source heat pump. While increased heat recovery loop can make full use of energy of the system and prevent thermal pollution, which has a strong practical significance. This article introduces the design procedure and operation modes of the system and proposes the optimal collector area and the best match with heat pumps; the search for the best operation modes and control strategies, offering better services for heating the biogas digester. |
| Keywords: | Solar-heat pump Anaerobic digestion Waste heat recovery High temperature fermentation high temperature heat pump |
