Final answer:

A Dry Pipe Sprinkler System is designed to prevent freezing of the water in the pipes and is used in cold climates. It works by keeping the valve closed using air pressure in the pipes, and when a sprinkler head opens during a fire, the air is released and water flows through the pipes to extinguish the fire.

Step-by-step explanation:

In a Dry Pipe Sprinkler System, a dry pipe valve is installed at the point where the water supply enters the system, and the piping is filled with air under pressure. The purpose of this system is to prevent freezing of the water in the pipes, which is especially important in cold climates. The air pressure in the pipes keeps the valve closed, and when a sprinkler head opens due to a fire, the air is released and the water is able to flow through the sprinkler system and extinguish the fire.
