In a controlled media system, which agent is typically used?

In a controlled media system, low-pressure steam is often used due to its effective heat transfer properties and versatility in various applications. Steam can easily be distributed through piping systems and applied for heating purposes, making it ideal for maintaining consistent temperature control in a building environment.

Additionally, low-pressure steam systems offer benefits such as higher thermal efficiency and the ability to provide uniform heating across different areas. This type of system can also integrate well with existing heating infrastructure, allowing for quicker adaptation and reduced energy costs.

Chilled water and refrigerant are typically associated with cooling systems, while natural gas is generally used as a fuel source rather than a media for heat transfer in controlled environments. Hence, low-pressure steam stands out as the agent commonly utilized in controlled media systems for heating operations.
