coefficient of performance造句

the coefficient of performance (COP) of vapor-compression systems are improved by 11.78% and 16. 38%;

Through experiment, the relation figures of engine rotation speed, coefficient of performance of heat pump and engine thermal efficiency are presented and analyzed.

It points out that the relation between optimal heating rate and coefficient of performance of a Carnot heat pump is useless.

The results show that the parallel-flow cycle yields the highest coefficient of performance among the cycles while the maximum pressure and temperature in the reverse-flow cycle are lowest.
