Final answer:
To prevent potential damage from freezing temperatures, dry pipe sprinkler systems are used, as they contain air instead of water when not active. In agriculture, water is intentionally sprayed on crops like oranges to utilize the heat released during freezing to protect the fruit.
Step-by-step explanation:
The type of sprinkler system used in areas where there is a potential for freezing temperatures is known as a dry pipe system. Unlike traditional wet pipe systems, which have water constantly in the pipes, dry pipe systems are filled with pressurized air or nitrogen.
When the system is activated, the pressure changes and opens a valve, allowing water to flow into the pipes and out through the sprinklers. This design prevents water from being in the pipes when they're not in use, thus mitigating the risk of pipes freezing and bursting.
Additionally, it's interesting to note that the principle of latent heat release during the phase change of water from liquid to solid is harnessed in agriculture. For instance, orange growers spray water on trees in anticipation of freezing temperatures. As the water freezes, it releases energy, which helps to keep the temperature of the oranges above freezing, thus preventing damage to the fruit.
