Envelope Design’s Importance for Energy Savings in Cold Store
The envelope design for the refrigerated sections of a facility serve an important role. These envelopes reduce heat transfer and control moisture infiltration and condensation. Heat transfer through refrigerated space walls and the outside ambient environment creates a greater load.
Moisture in refrigerated spaces comes with a litany of disadvantages:
- Increased Energy Costs
- Diminished Insulating Effect
- Structural Damage
- Biological Growth
- Ice/Frost Formation
About one third of cold storage heat gain is through the envelope. Insulation of the envelope surrounding the refrigerated space and the external building shell will both be important. The warehouse can be modeled with the incremental improvements in varying thickness of insulation in wall, floors and roof systems. Each type of insulation delivers unique performance characteristics. Research all available options thoroughly to ensure maximum benefit.
The critical failure points for roofs will be water and vapor leaks. The roof serves an important structural role. There are three important considerations when designing a successful roof system:
· Maintaining structural integrity at all times.
· Sealing all joints to prevent air and moisture infiltration.
· A required uninterrupted vapor retarder.
Types and designs of walls will be important. The current trend in the industry is to use preformed materials such as prefabricated insulated metal panels and insulated concrete.
External walls must accommodate loads incurred as a result of the physical environment (i.e. wind and rain). Vapor and heat transfer control must also be included. External walls contribute to energy efficiency for the facilities’ entire heating and cooling load, not just refrigerated spaces.
Internal wall design and configuration will vary depending on facility layout. If cold storage spaces sit adjacent to one another, no need exists to insulate the adjoining walls. If a refrigerated space will be individually insulated, then different design specifications must be considered. The internal walls of refrigerated rooms must also adhere to food safety regulation. With that in mind, wall materials or surfaces must be washable in addition to sealed and vapor retardant.
Air infiltration through open doors can represent 50 percent or more of the total refrigeration load. Cold storage doors come in a myriad of choices—all with varying aspects that affect energy use and functionality. Modern cold storage doors may need to accommodate products handled by automated processes at high volume with rapid turnover.
Three important factors will influence design and choice concerning doors:
- How the door will be used
- How often it will be used
- The space required for a forklift, its load, and the mast to pass through without hitting the door
Designers will also need to consider:
- Door Activation methods
- Life cycle costs

Could you please share your views on Cold Chain Sector for our magazine readers?
The Indian cold chain industry, once limited only to a few produce types till as late as the first decade of this century, is transforming from traditional quantity stores for stand-alone commodities to quality cold chain- hence integrating various missing links.
Thus, various business models utilizing cold chain logistic services at different stages have been recognized and well established on commercial lines.
Few, worth mentioning are bulk stores in the areas of concentrated centers of production, multi-commodity multi-chambers cold stores around areas of consumption, controlled and modified atmosphere cold stores, fruit ripening chambers, IQF and blast freezing, freeze stores etc.
More important is the trend towards complete refrigerated supply chain for the fresh and processed items like, milk and dairy, meat, confectionary and pharma, and of course, the fresh produce.
The Indian market is on the cusp of a revolutionary change with the expansion of middle class and affluence coming into the middle classes. The increase in demand for fresh produce, meat and perishable packaged foods is leading to significant growth in this sector, which is increasingly relying on sustainable cold chain network.
India is one of the largest producers of agricultural produce and has abundant supply base of different produce.
There is an increasing awareness that agri-logistics require to develop with a delivery bias, to link with demand across regions, and not merely as a buffer against local demand. Distance and time assumes importance as the disparity of prices also induces movement.
