Refrigerant piping installed in concrete floors should be encased in what?

In refrigeration systems, it is essential to protect refrigerant piping, especially when it is installed in concrete floors. Encasing these pipes serves multiple purposes such as safeguarding against physical damage, preventing leaks from contaminating the concrete, and ensuring proper thermal management.

The use of pipe ducts for encasing refrigerant piping provides a protective barrier that allows for flexibility in installation and maintenance. Pipe ducts are typically designed to withstand the stresses of the concrete and can accommodate any expansion or contraction of the piping due to temperature changes. This reduces the risk of the pipes being damaged by the surrounding concrete or other environmental factors.

Additionally, using pipe ducts ensures that any potential leaks can be contained and monitored more effectively. It allows for better insulation to be applied if necessary, preventing heat loss or gain, which is crucial for maintaining the efficiency of the refrigeration system.

While other options, such as PVC ducts or insulated sleeves, may serve specific purposes, pipe ducts specifically address the need for robust protection and compatibility with concrete environments, making them the preferred choice in this scenario.
