Question 452General Subjects - Assistant Engineer

The correct answer is A) Dry expansion cooling coils are usually the finned-coil type and horizontally installed. This is the correct answer because dry expansion cooling coils, which are commonly used in air conditioning systems, typically utilize a finned-coil design and are installed in a horizontal orientation. The finned-coil construction maximizes the surface area for heat transfer, while the horizontal installation allows for efficient airflow and drainage of condensate. The other options are incorrect because bare-coil designs are less common for dry expansion cooling coils, and a vertical installation would not be as efficient for these types of systems.
