变工况涡旋压缩机性能拟合方程的建立

采用最小二乘法原理建立涡旋压缩机的性能拟合方程，提供变工况时以蒸发温度、冷凝温度或蒸发压力、冷凝压力相关的压缩机五大性能参数（质量流量、制冷量、输入功率、运行电流、COP）的通用拟合方程。为建立完整的空调和制冷系统提供数值计算，为空调和制冷系统的动态特性模拟和优化设计提供通用、方便的数学模型。

Performance fitted equations establishment of scroll compressor under variable conditions

Focuses on building performance fitted equations of scroll compress by using one kind of mathematic method which provides general fitted equations of five thermodynamics performance parameters such as mass of flow, refrigerating capacity, power consumption, operation current and COP by inputting evaporating temperature, condensing temperature or evaporating pressure, condensing pressure under variable conditions. With this method, mathematical model is offered, which is convenient to analysis calculation, dynamics modeling and optimization design of a complete air condition or refrigeration system.
