Performance Investigation and Application of Air-Source High-Temperature Heat Pump Coupled with Steam Compression System
摘要
Abstract
To address the industrial demand for high-temperature heat without recoverable waste heat,an air-source high-temperature heat pump coupled with a steam compression system as a replacement for conventional fuel-fired boilers is developed in this study.The system employs an R410A/R245fa cascade cycle to extract low-grade heat from ambient air and delivers high-temperature steam at 150 ℃ via a steam compressor.Simulation and experimental results indicate that,under an ambient temperature of 20 ℃ and a steam output of 125 ℃,the air-source high-temperature heat pump delivers a heating capacity of 121.5 kW with a coefficient of performance(COP)of 1.71,while the steam compressor provides stable steam at 145 ℃ and 1.65 t/h under an intake temperature of 115 ℃,with deviations between simulation and measurements within 5%.Pilot demonstration shows that the system can stably produce 150 ℃ steam at 30 ℃ ambient temperature,achieving a COP of 1.65,an annual operating cost saving of approximately 2 649 000 yuan,and a payback period of 1.79 years,demonstrating notable economic benefits and application potential.关键词
