Performance Analysis of a Solar Hot Water Thermal Storage Frost-suppression Air-source Heat Pump Drying System in High Altitude Cold Plateau Regions
摘要
Abstract
To address the significant performance degradation of air-source heat pumps caused by evap-orator frosting under low-temperature and high-humidity conditions,an air-source heat pump drying system incorporating solar hot water thermal storage was proposed to delay evaporator frosting.Com-parative experiments were conducted using Inula helenium as the drying material.The results indicate that the solar hot water thermal storage frost-suppression effectively enhances the operational stability and drying efficiency of the system under low-temperature conditions.At an average ambient tempera-ture of-3.96℃,the average heating capacity of the proposed system increased by 82.78%compared with that of a conventional air-source heat pump drying system,while the coefficient of performance(COP)increased from 1.00 to 1.83.Moreover,over the entire drying cycle,the time required for the system to reach the target drying temperature was reduced by 18.47%relative to the conventional heat pump drying system.关键词
