What would likely cause a reduction in the efficiency of a cooling plant?

A reduction in the efficiency of a cooling plant is most accurately associated with a high pressure ratio. When the pressure ratio is high, it indicates that the difference between the high and low pressures in the system is significant. This can lead to increased energy consumption, as more work must be done by the compressor to maintain the necessary pressure and temperature differentials within the system. This scenario typically results in less efficiency because the system must exert more energy for the same cooling output.

In addition to energy losses, a high pressure ratio can cause operational challenges, such as increased wear and tear on components due to higher stress levels, ultimately leading to higher maintenance costs and potentially reduced lifespan of the equipment.

The implications of operating under these conditions make it essential to optimize the pressure ratio for efficient system performance. Lowering the pressure ratio can improve the system’s efficiency by requiring less work from the compressor and thus consuming less energy overall.
