可燃制冷剂空调器性能测试试验台的研制

摘要

With the rapid development of modern refrigeration industry and rising of living standard, household air-conditioner has entered to ordinary families. Air conditioner needs rigorous test by related department before putting into market. At present, air conditioner is mainly tested for its performance by the enthalpy difference laboratory;this method has been widely accepted due to fast speed and small error. In order to protect the ozone layer and reduce the greenhouse effect, environmentally friendly hydrocarbon refrigerant gradually replaces traditional refrigerants in modern refrigeration industry and has been widely used in the household air-conditioner, while, the inflammable and explosive defects of organic refrigerants is also an inevitable fact.%随着现代制冷工业的迅猛发展及人们生活水平的日益提高，家用空调器已进入普通家庭，空调器在投入市场之前均需相关部门进行严格的检测。目前，国内主要采用空气焓值法对空调器进行其性能的测试，该方法测试速度快误差小，应用广泛。为了保护臭氧层及降低温室效应，现代制冷工业以逐渐开始用环境友好型碳氢化合物制冷剂取代传统制冷剂，并已在家用空调器中逐渐开始使用。碳氢化合物冷剂的缺点是，发生泄漏的情况下易燃易爆。
