OPR documentation serves as a guiding document for the design and construction teams, ensuring that the refrigeration system is designed and built to meet the owner’s specific requirements. A well-documented OPR helps designers create a system that meets the owner’s performance, efficiency, and safety expectations, while contractors can use the OPR to ensure that the installed system meets the design specifications. This reduces the likelihood of errors, omissions, and rework, ultimately saving time and costs.
