本欧洲标准描述了从能源消耗的观点来看，用于空间制冷和/或加热的建筑空调系统的常见方法。检查可以考虑以下几点来评估系统的能量性能和适当尺寸: - 系统符合原始和随后的设计修改，实际要求和建筑物的现状。 - 正确的系统运行。 - 各种控制功能和设置。 - 各种组件的功能和配件。 - 电源输入和最终的能量输出。 不是要对空调系统进行全面的审计，而是对其功能和对能源消耗的主要影响进行正确的评估，从而确定对改进系统或使用替代解决方案的任何建议。针对能源效率和符合本标准主要目标的国家规定和指导方针也适用。 注意EN 15239中提供足够的通风和系统平衡。 本标准不包括负责检查的人员或组织的资质，但涉及检查要求。 频率th

This European Standard describes the common methodology for inspection of air conditioning systems in buildings for space cooling and or heating from an energy consumption standpoint. The inspection can consider for instance the following points to assess the energy performance and proper sizing of the system: - System conformity to the original and subsequent design modifications, actual requirements and the present state of the building. - Correct system functioning. - Function and settings of various controls. - Function and fitting of the various components. - Power input and the resulting energy output. It is not intended that a full audit of the air conditioning system is carried out, but a correct assessment of its functioning and main impacts on energy consumption, and as a result determine any recommendations on improvement of the system or use of alternative solutions. National regulations and guidelines targeting energy efficiency and in line with the main objectives of this standard are also applicable. NOTE Provision of adequate ventilation and system balancing are dealt with in EN 15239. The qualification of the persons or organisation responsible for inspections is not covered by this standard, but the requirements for inspections are covered. The frequency of the mandatory inspection is defined on national level. Features affecting the frequency and duration of inspection are introduced in Annex C.
