摘要
空气源热泵的运行性能主要受进风条件影响,高原环境的低气压可能导致空气源热泵的制热量和性能系数明显降低,需采取措施进行处置;现行检测方法未对气压条件对热泵能效指标的影响给予合理的考虑,可能导致对能效检测结果的误判;高原环境在电气安全方面有其特殊性,预期在海拔2000m以上地区使用的空气源热泵产品通常需要进行针对性的设计变更以满足要求。
The operation performance of air source heat pump is mainly affected by the air inlet conditions, low atmospheric pressure in high altitude environment may lead to air source heat pumps heating capacity and coefficient of performance decrease, need to take measures for disposition ; existing testing technical method does not yet give reasonable consideration to the influence of atmospheric pressure condition on heat pump energy efficiency index, energy efficiency test results may lead to a miscarriage of justice; high altitude environment has its particularity in electrical safety, is expected to air source heat pump used in products at altitude 2000m above usually need to change to meet the requirements of design.
