c. smaller locked-rotor amperage
d. limited effect of a compressor malfunction



Answer :

The primary advantage of parallel compressor systems is their: a. higher efficiencies: Parallel compressor systems are known for their ability to enhance energy efficiency in HVAC (heating, ventilation, and air conditioning) systems. By utilizing multiple compressors running in parallel, the system can more effectively match the varying cooling demands of a space, leading to improved overall efficiency. b. nearly exact load matching ability: These systems excel at closely matching the load requirements of the building or space they are cooling. By having multiple compressors that can adjust their output based on the demand, parallel compressor systems can ensure that the cooling capacity closely aligns with the required load, optimizing performance and comfort. c. smaller locked-rotor amperage: Parallel compressor systems often exhibit smaller locked-rotor amperage compared to single compressor systems. This can result in reduced electrical stress during startup, leading to smoother operation and potentially extending the lifespan of the equipment. d. limited effect of a compressor malfunction: In the event of a compressor malfunction in a parallel system, the impact is often limited. Since the system consists of multiple compressors working together, the failure of one compressor does not necessarily lead to a complete system shutdown. The remaining compressors can continue to operate, albeit at a reduced capacity, maintaining some level of cooling until the issue is addressed. These advantages highlight the effectiveness of parallel compressor systems in optimizing energy efficiency, load matching, electrical characteristics, and system reliability in HVAC applications.
