Introduction
Combined pressured gas systems have been increasingly used in heating and cooling for both commercial and domestic applications due to the convenience, efficiency and safety associated with them. As such, the design of a combined pressured gas system is an important process that must be undertaken carefully to ensure the safety of users and the environment. In this paper, the design of a combined pressured gas system for a commercial building is discussed.
Design Considerations
The first step in the design process is to consider the type of fuel that will be used in the system. This will typically be natural gas or propane, although other fuels may be suitable depending on the location of the building and the availability of fuels. The type of fuel chosen will determine the types of components that are used in the system, including the gas regulator, safety valves, and other accessories.
The second step in the process is to determine the maximum operating pressure that the system will need to be able to handle. This will be dependent on the type of fuel and the amount of fuel that will be consumed by the system, and must be higher than the maximum pressure rating of any components used in the system.
The third step is to consider the type of detection and control systems that will be used. These systems are responsible for detecting any issues with the system and activation of safety devices when needed. This could include a pressure switch connected to a safety valve, a flame detector and a thermal fuse, as well as other components based on the design requirements.
The fourth step is to consider the type of ventilation system that will be used to ensure that the gas is properly ventilated, and that any dangerous fumes are safely dispersed. This could include the installation of exhaust fans or even an Inspection, Testing and Balancing (ITB) system. The ventilation system should be designed with the necessary safety components in mind.
Finally, the fifth step is to consider the piping and tubing required for the system, including the material and type of fittings that will be used. This is an important factor to consider, as the type and size of pipe used can have a major impact on the performance of the system.
Conclusion
The design of a combined pressured gas system is an important process that must be carefully considered. By ensuring that all the design considerations discussed in this paper are taken into account, a safe and efficient system can be designed that meets all the requirements of the user.
