摘　　要：介绍了变温环境室空调系统实验装置,研究分析了不同工况下室内温度分布、压缩机启停周期、制冷量及COP等运行参数的变化情况。实验结果表明:室内控制温度越接近坐落环境温度,温度波动幅度越小,不同位置的温差也越小;与理论值相比,压缩机的制冷量及COP随环境室温度升高而升高,理论制冷量大于实际制冷量;而压缩机启停比,无论理论值还是实验值,均呈现从低温到高温下降的趋势,但低温时实验值接近于理论值,高温时低于理论值。This paper introduces experimental facilities on air conditioning system of variable temperature ambient chamber. Researching and analysis the operating parameters of temperature distribution, compressor start-stop cycle and cooling capacity and COP changes. The results showed that the closer chamber controlled temperature is located to the ambient temperature, the smaller the temperature fluctuations is, temperature difference is also smaller; compared with the theoretical value, with ambient chamber temperature rising, compressor cooling capacity and COP rise; theoretical cooling capacity is more than the actual cooling capacity and compression of the start-stop, regardless of the theoretical value or experimental values, showed a downward trend from low to high, but the low temperature test values close to the theoretical value, when the high temperature is lower than the theoretical value.
