Question

List ways to change the compressor capacity to match the system load.

Answer 1

There are several ways to change the compressor capacity: adjusting motor speed, using multiple compressors, and utilizing variable displacement compressors.

Step-by-step explanation:

There are several ways to change the compressor capacity to match the system load:

1. Adjusting the speed of the compressor motor: By increasing or decreasing the speed of the motor, the compressor capacity can be changed. A higher speed increases the capacity while a lower speed decreases it.
2. Using multiple compressors: Multiple compressors can be connected in parallel or series to increase or decrease the overall capacity of the system.
3. Utilizing variable displacement compressors: These compressors have the ability to vary the amount of refrigerant they pump, allowing for capacity adjustment.
