进水温度对环保工质船用空调机组性能影响研究

Impact Study Properties of Marine Air-conditioning Unit with Refrigerant R410A at Varied Inlet-water Temperature

对于采用环保工质 R410A 的小型船用空调机组,进行变进水温度的制冷实验。通过实验测试,得到机组制冷量、制热量、输入功率、COP、吸排气压力、吸排气温度、蒸发温度、冷凝温度等特性参数随进水温度的变化规律。由此,可根据中国近海水温分布的特点,对机组在不同季节的运行特性和能耗作出分析。

For a small marine air-conditioning unit with environmentally friendly refrigerant R410A, an experiment on cooling or heating situation was performed by changing the inlet-water temperature. Through the test, the relation between parameters which includes cooling capacity, heating capacity, power input, COP, EER, suction pressure, discharge pressure, suction temperature, discharge temperature, evaporating temperature and condensing temperature and inlet-water was obtained. As a result, according to the distribution characteristics of Chinese sea water temperature, the operating characteristics and energy consumption of units in different seasons can be analyzed.
