I really can’t figure out why B was chosen. Please advise, experts! O(∩_∩)O Thank you
Option A should be chosen. According to Article 4.2.2 of the standard CJJ34-2010, \"when a thermal power plant or a large-scale district boiler room serves as the heat source, the designed supply water temperature can range from 110 to 150 degrees, while the return water temperature should not exceed 70 degrees.\"
Thanks, buddy. There are too many mistakes in that practice set. . .
Page P302 of the textbook also mentions similar situations: high-temperature hot water pipes, pipes in large centralized heating systems; the normal supply water temperature is 110–150, while the return water temperature should not exceed 70
