Reviewing Proposed Energy Efficiency Standards for Ice Machines

Reviewing Proposed Energy Efficiency Standards for Ice Machines

Earlier this year, the Department of Energy (DOE) published a notice of proposed rulemaking (NOPR) outlining new energy conservation standards for automatic commercial ice makers (ACIMs). The proposal calls for energy reductions up to 30 percent, which would apply to most of the ACIM equipment currently on the market. In a recent article for QSR Magazine, I explored the implications of this new DOE proposal within the context of an already dynamic regulatory climate.

A2L Refrigeration Overview — Systems, Safety and Servicing Considerations

A2L Refrigeration Overview — Systems, Safety and Servicing Considerations

As recent regulations set the stage for the use of A2L refrigerants in HVACR, commercial refrigeration stakeholders have questions about system design, safety considerations and servicing best practices. Whether you’re an original equipment manufacturer (OEMs), system designer or service technician, working with lower-flammability A2Ls will require familiarity with standards and procedures that ensure system safety. In a recent article for RSES Journal, I provided an overview of the A2L equipment landscape and discussed how it impacts system design and servicing.

Cross-border Considerations for Improving International Cold Chain Management

Cross-border Considerations for Improving International Cold Chain Management

Maintaining consistent holding temperatures and following proper quality assurance (QA) processes are especially critical as shipments cross borders into foreign countries. But implementing proper cold chain management best practices can be even more difficult within international shipping lanes, as the export process introduces a variety of additional considerations and potential hazards to perishable quality.

CO2 as a Refrigerant – Properties of R-744

CO2 as a Refrigerant – Properties of R-744

Carbon dioxide is a naturally occurring substance; the atmosphere is comprised of approximately 0.04 percent CO2 (370 ppm). It is produced during respiration by most living organisms and is absorbed by plants. It is also produced during many industrial processes, in particular when fossil fuels such as coal, gas or oil are burned to generate power or drive vehicles.

CO2 as a Refrigerant – Selecting a Best-Fit System for Your Operation

This is post number 13 of a series. Selecting the Best System – Booster Versus Cascade Versus Secondary Table 1 lists the advantages and disadvantages of cascade, transcritical, and secondary retail systems Conclusion Transcritical operation is generally less efficient than subcritical operation, so system type selection is usually driven by the ambient temperature profile

Best Practices for Monitoring and Securing Cross-Border, Cold Chain Shipments

Best Practices for Monitoring and Securing Cross-Border, Cold Chain Shipments

In the best of circumstances, the task of shipping perishable product is fraught with challenges. But maintaining consistent holding temperatures and following proper quality assurance processes is even more difficult when shipping goods in the global cold chain — especially when shipments cross borders between countries. In a recent article for Fresh Plaza, I reviewed the leading strategies for addressing the security risks of shipping perishable goods in the global cold chain.
