A crankcase pressure regulator is primarily found in walk-in freezers, where it helps maintain consistent pressure in the compressor. This component is less common in other types of refrigeration systems such as high-capacity chillers or residential air conditioners. Efficient pressure management is essential for the operation of walk-in freezers. ;
The crankcase pressure regulator is primarily found in walk-in freezers, where it manages compressor pressure for optimal function. This component is not commonly used in other refrigeration systems like high-capacity chillers or residential air conditioners. Therefore, the correct answer is d) Walk-in freezers.
