摘要
提出了测量房间空凋器制冷量的一种新方法——电热平衡-焓差法,两种测量系统被合并在同一个测试装置中.该新方法是风管热平衡法的改进,由电热平衡法所得的制冷量测量值可用焓差法来校核.此装置还可用来测量房间空调器在热泵运行时的制热量.试验结果与国家权威试验台的测量值进行了比较.最后,简要地对测试数据的误差作了分析.
A new method of rating cooling capacity of room air conditioner has been introduced. Two measurement systems (electric heat belance and enthalpy difference method) are combined into a same testing device. The new method is a improvement of air-duct heat balance method. The measurement value of cooling capacity which is got from the electric heat can be checked by use of the enthalpy difference method. The devices can be used to measure heating capacity of room air-conditioner in heat pump. operation. Testing results have been compared with rating Values of the national authoritative measurement set. At last, the errors of testing data have been analysed briefly.
