Welcome to the Refrigeration Showcase, which includes comprehensive coverage of the different types of equipment and controls commonly encountered in the field. From ice machines to reach-ins to controls and components, the Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available, so they can help their customers make the right choice for their application.

Figuring out which refrigeration equipment or controls package will work best for an application can be challenging. Larger supermarkets, cold storage facilities, and restaurant chains often have in-house personnel who make this decision, but they still value the input from their local contractors who service their equipment. Smaller regional stores and restaurants typically do not have these in-house resources, so contractors usually have a larger role in recommending equipment solutions.

For both these situations, the Refrigeration Showcase will help contractors learn which ice machine, refrigeration unit, component, and/or control will best serve the needs of their customers. Manufacturers have provided detailed information for the Showcase that includes the benefits end users will experience by using their products, as well as how they have made their equipment easier for contractors to install and service.

For food retailers, their priority is making sure that any new equipment keeps their products safe, fresh, and cold — reliably and efficiently. The products highlighted in the Refrigeration Showcase are designed to do just that.

The CO2 Adaptive Liquid Management

Product: The CO2 Adaptive Liquid Management (CALM) combines Danfoss’s Liquid Ejector and Adaptive Liquid Control (ALC) case controller algorithm to pull liquid CO2 refrigerant from the suction side and inject it into the evaporator of display cases and cold rooms, regardless of climate.

Details: CALM is a complete solution, with not only an intelligent system manager and smart pack and case controllers, but also two Danfoss innovations: the ALC case controller algorithm and the Liquid Ejector. The Liquid Ejector uses expansion energy from the gas cooler to efficiently remove liquid from the suction side. The ALC case controller algorithm then safely injects more refrigerant into the evaporator, increasing evaporation temperature and raising controlling superheat close to zero. Together, these components optimize evaporator performance, increase suction pressure, and decrease compressor energy consumption.

Features: Use of the Liquid Ejector and ALC enable full utilization of the evaporator’s surface to provide — without equipment change — up to 10 percent greater energy efficiency on top of savings inherent with CO2.

Benefits: CALM reduces first-time investments; for example, with less liquid in the suction line, the size of the suction accumulator can be reduced. Required compressor capacity can also be reduced, allowing for smaller or fewer compressors to be used. CALM is a cutting-edge CO2 solution for all climate zones and store sizes and helps food retailers all over the world transition to CO2 as a refrigerant. Increasing the evaporating temperature increases suction pressure, thereby reducing both the compressor load and the energy it consumes. CALM can typically achieve energy savings 5 percent better than minimum competitive active superheat management systems and 10 percent better than fixed superheat solutions.

Service, maintenance, and installation: The physical requirements for the CALM algorithm include Danfoss case controllers (i.e., AK-CC 550A, AK-CC 55) at all evaporators and a Danfoss pack controller (i.e., AK-PC 782A) to control the rack, as well as a suction accumulator with liquid level indicator and liquid ejector connected to the suction accumulator.
