How to design and analyse a refrigeration system?

To design and analyse a refrigeration system, we want to know what the thermodynamic properties will be for the refrigerant at our four key components. Point 1: between the evaporator and the compressor. Point 2: as it leaves the compressor. Point 3: when it leaves the condenser, before it enters into the expansion valve.

Can energy modelers model refrigeration systems?

Energy modelers should be aware that modeling of refrigeration systems is not standard. Many commercially available programs do not have the ability to accurately model refrigeration systems. If a simulation program cannot model the system, exceptional calculation methodology per LEED requirements shall be used.

Are industrial refrigeration systems energy-efficient?

This Guide identifies and discusses best practices for making industrial refrigeration systems both energy-efficient and productive. The highest levels of efficiency in these systems are achieved through a combination of design, construction, commissioning, operation, and maintenance coupled with a robust energy management program.

What should be included in a refrigeration system design?

Particular attention is paid to the design of insulation and vapour retarders. Refrigeration system design is discussed in detail, including load calculations, system types and components, refrigerants, controls and instrumentation, blast coolers and freezers, and cryogenics.

What factors influence a refrigerator system's best practices?

Existing system constraints, energy rates, and utility or government incentives can all significantly influence which best practices are economically viable for a specific system. Refrigeration system “lift” is the difference between suction pressure and discharge pressure.

What is commissioning a refrigeration system?

Commissioning is the inspection, review, and adjustment of set points, control strategies, and equipment features, so as to achieve the design intent and meet original specifications, in a way that maximizes performance and efficiency. It ensures that you get what you pay for in your refrigeration system.
