| 摘 要： | 以两种产品为例，归纳了半封闭螺杆式和活塞式冷水机组的特点，分析了在不同冷水出水温度及不同制冷量情况下两种机组的性能，认为它们的制冷量、输入功率及COP值的变化趋势相近，但螺杆式冷水机组的COP值较活塞式的约高0.5.

| Abstract: | Takes two kinds of chillers as exemples, sums up the characteristics for semi hermetic reciprocal type and semi hermetic screw type units. Analyses the performances of units at variable temperatures and at variable refrigerating capacities. Considers that the variety of refrigerating capacity, input power and COP are similar, but the COP for screw type units is higher than that of reciprocal type units by 0.5. |
