Research on performance test condition of integrated heat pump environment control unit with outdoor air
摘要：
近零能耗建筑近年来在我国迅速发展，推动了热泵型新风环境控制一体机的应用。通过市场调研，分析其功能，梳理得到了其主要性能评价指标，并对性能指标的测试工况进行了研究，提出了基于实际运行需求的一体机制冷、制热性能综合测试工况。在综合测试工况下，热回收效率满足近零能耗建筑产品性能指标要求，回收冷量占一体机供冷量的14.1%，机组制冷性能系数为3.63，比GB/T 7725—2004测试工况的测试结果提高了21.8%；回收热量占一体机供热量的17.5%，机组制热性能系数为3.87，比GB/T 7725—2004测试工况的测试结果提高了21.3%。综合测试工况下取得的测试结果可以更加科学合理地指导近零能耗建筑产品设备选型及设计。
Abstract：
Nearly zero energy buildings (NZEB) have developed rapidly in China in recent years, which has promoted the application of integrated heat pump environment control unit with outdoor air (IEU). Sorts out the main performance evaluation indicators of IEU through market investigating and function analysing. Studies the test conditions of the performance indicators and puts forward a new test condition for the IEU’s cooling and heating capacity. The heat recovery efficiency under the new test condition meets the requirements of NZEB products. The recovered cooling accounts for 14.1% of the total cooling capacity, and the COP of the IEU is 3.63, which increases by 21.8% compared with the test results of GB/T 7725-2004. The recovered heat accounts for 17.5% of the total heating capacity, and the EER of the IEU is 3.87, which increases by 21.3% compared with the test results of GB/T 7725-2004. The test results under the comprehensive test conditions can scientifically and rationally guide the equipment selection and design of NZEB.
