Calculation Method for Energy Efficiency and Carbon Efficiency Ratio of In-Service Multi-Connected Air Condition(Heat Pump)Unit

本文创新提出了一种在役多联式空调(热泵)系统运行能效及碳效比计算方法,即在规定的测试周期内,通过将现场测试数据按不同温度点进行分类,依据标准规定的发生时间数,计算对应温度点下系统的制冷量、耗电量、碳排放量、全年运行性能系数。并基于此计算对应的碳效比,即在规定的系统核算边界内,多联式空调(热泵)系统在规定的试验期间内碳排放总量与其功能贡献总和之比。最后以实际测试项目为例进行计算,本文为在役多联机(热泵)系统节能低碳评价标准的制定提供技术参考和数据支撑。

This article innovatively proposes a method for calculating the energy efficiency and carbon efficiency ratio of in-service multi-connected air condition(heat pump)unit.Within a specified testing cycle,the on-site test data is classified according to different temperature points,and the corresponding cooling capacity,power consumption,carbon emissions,and annual operating performance coefficient of the system are calculated based on the specified occurrence time according to the standard.And based on this,calculate the corresponding carbon efficiency ratio,which is the ratio of the total carbon emissions of a multi-connected air condition(heat pump)unit during the specified test period to the total functional contribution within the prescribed system accounting boundary.Finally,taking actual testing projects as an examplefor calculation,this article provides technical reference and data supportforthe formulation of energy-saving and low-carbon evaluation standards for in-service multi unit(heat pump)systems.
