摘　　要：针对煤矿井筒防冻这种特殊供热需求,本文采用分体式热管作为空气源热泵的冷凝换热器,空气源热泵采用低冷凝温度,小压比高效运行,根据热力学第二定律,热泵系统能效比高,同时可以在低温环境下安全运行。通过实验样机测试,验证了热泵系统小压比运行能效比很高,同时热管换热器可以提供较高温度的热风。通过2023年冬季在邢东煤矿井筒防冻的工业实验应用,验证了小压比高效能空气源热管热泵系统完全可以满足井筒防冻供热需求,能够为煤矿井筒防冻提供能源应急保障、同时系统稳定,在环境温度-20℃下不但可以可靠供热,系统能效比也超过了3.0,远高于传统空气源热泵,节能效果显著、运行安全。该技术为煤矿提供了节能、安全的井筒防冻技术手段。In this study,a split heat pipe is utilized as the condensing heat exchanger for an air source heat pump to meet the specific heating requirements for preventing freezing in coal mine shafts.The air source heat pump operates efficiently with low condensing temperature and low pressure ratio.Based on the second law of thermodynamics,the energy efficiency ratio of the heat pump system is high,enabling safe operation in low temperature environments.Experimental prototype testing confirms that the energy efficiency ratio of the heat pump system remains high under low pressure ratio operation,and that the heat pipe heat exchanger can provide high temperature hot air.Industrial experimental application at Xingdong Coal Mine during winter 2023 verifies that the low pressure ratio and highly efficient air source heat pipe heat pump system fully meets shaft antifreeze heating requirements,providing energy emergency guarantee and stable operation.Under ambient temperatures of-20℃,it not only provides reliable heating but also exceeds a 3.0 system energy efficiency ratio,surpassing traditional air source heat pumps and demonstrating remarkable energy-saving effects while ensuring safe operations.
