TS EN 378-1

TS EN 378-1 is the core part of the refrigerating systems and heat pumps series, setting out the framework for safety and environmental requirements. This part focuses on basic requirements, definitions, classification and selection criteria, so it helps explain how different system types are distinguished and what technical factors are used when selecting an appropriate system.

Core concepts and why they matter

Refrigerating systems and heat pumps are thermodynamic systems that move heat from one place to another. In practical use, they appear in commercial refrigeration, air conditioning, process cooling and energy recovery applications. For that reason, safe design and correct classification depend on assessing several variables together, such as refrigerant type, system size, intended use, installation location and operating conditions. The conceptual framework in this first part provides the basis for understanding the more detailed technical requirements found in the later parts of the series.

Operation, maintenance and refrigerant recovery context

According to the supplied scope information, the standard is not limited to design principles; it also gives guidance for the operation, maintenance and repair of refrigerating systems and establishes procedures for refrigerant recovery. In general technical terms, these activities matter because a system must be handled carefully throughout its life cycle to reduce leakage risk, limit environmental impact and keep service work controlled. Proper refrigerant recovery is one of the key practices that supports both system performance and environmental protection.

This record belongs to Part 1 of the series, so it provides the foundational terminology and classification structure used to interpret the basic rules and selection criteria in the title. It represents the introductory general provisions and defining framework of the series, not the entire set of requirements across all parts.
