Refrigeration systems are an essential element of contemporary life, with applications ranging from industrial production to food processing to home and commercial air conditioning. The field of refrigeration systems is getting increasingly regulated. Such regulations, in the end, increase sustainability while decreasing energy consumption, which has huge implications for those of us in the foodservice industry.
When designing a custom refrigeration system to meet their needs, facility owners must consider a number of different factors. While these factors are weighted differently from project to project, they are all essential components of a refrigeration system.
Here are six of the most crucial considerations:
Safety
First and foremost, a refrigeration system must fulfill four key safety criteria. The first consideration is the safety of the refrigerant in terms of flammability, toxicity, and other possible risks. Following that, the system’s own safety must be addressed in order to prevent it from inadvertent harm.
Third, the equipment’s safety hazards must be examined. Ceiling-hung evaporators, for example, pose a potential safety hazard if they become loose. Finally, the operating charge — or the amount of refrigerant in the system — has an impact on overall safety. Simply put, the higher the operating charge, the greater the risk.
Environmental
The majority of today’s sustainable design philosophy is to reduce the environmental concerns caused by refrigeration systems. The refrigerant you select is maybe the most critical component here. The global warming potential, or GWP, of refrigerants is measured. The higher a refrigerant’s GWP, the greater the environmental risk it presents.
Similarly, you must consider the total equivalent warning impact, or TEWI, of the overall refrigerant system. The TEWI rating expresses the carbon footprint of the system and includes factors such as the potential impact of refrigerant leakage and the energy consumption of the equipment. Water use must also be considered, as it can increase the environmental impact of systems that use a lot of water to reject heat.
Technology
Refrigeration technology has advanced rapidly in recent years. However, the newer the technology, the greater the danger of malfunctions and troubleshooting. Older, more matured technology, on the other hand, is considerably more predictable in terms of long-term performance as well as possible concerns.
You must also evaluate the equipment’s estimated life. The lifespan of various types of refrigeration systems varies greatly. Unitary systems, for example, have much shorter life expectancies than built-up systems. The technology manufacturer’s stability and customer support should also be heavily weighed.
Cost
When developing a sustainable refrigeration system, you must carefully account for all costs involved, just as you would when investing in any form of equipment. These expenditures include the capital costs of the equipment as well as any structural or building charges. You must also include in the cost of the refrigerant as well as the expenditures of running and maintaining the system.
Maintenance and Operations
A refrigeration system should also be customized to meet your specific operational and maintenance requirements. The system’s complexity, redundancy potential, overall space footprint, serviceability, and ability to accommodate future expansion are all important considerations. This category aims to forecast any future costs and difficulties associated with the system as accurately as possible.
Compliance with Regulations
Refrigeration systems are subject to a plethora of regulations that govern everything from their design to their environmental impact and operating standards. If you fail to account for all such regulations, you may face severe penalties in the future. As a result, it is always preferable to have an experienced professional guide you through the planning process.
