多联机新国标下的焓差实验室改进

介绍了多联机的发展和现状。对新旧标准对比研究,新标准对空调种类、性能指标、测试温度、连接台数等进行了改进。焓差实验室是国内研究空调的最主要方式。需要改进焓差实验室来满足新标准的修改,主要的改进方向为适应大风量高蒸发温度空调测试,增加水系统,降低能耗,系统精确控制,温度精确控制等方面。

Improvement of Enthalpy Difference Laboratory under the New National Standard

The development and current status of the VRV are introduced.Compared with the original standard,the new standard has been improved in air conditioning type,performance,test temperature,the number of connections and other units.Enthalpy difference laboratory is the main platform for domestic research on air conditioning technology.The enthalpy difference laboratory must be improved to meet the new standard.The major improving measures include the air conditioning test adapting to large volume high evaporation temperature,increasing of water system,reducing of energy system control precision,accurate temperature controlling,etc.
