摘要
本文在国内第一个VRV空调设备整机性能实验台上对变频控制热泵式VRV空调机组冬季运行工况进行了一系列实验研究 ,得到了室内机制热量、室外机功率随室内外温度的变化关系 ,机组在部分负荷时的能效比以及影响能效比的因素 ,并对除霜工况进行了分析。
On the first performance lab of VRV air-conditioner in China, this paper studies the operating performance of variable frequency control heat pump VRV air-conditioner in winter, derives the influences of indoor temperature and outdoor temperature to the heat capacity and power of the system,obtains the EER of partial heat load and the influential factor,analyses the operation of removing frost.
