Master-Bilt, manufacturer of a full line of premier commercial refrigeration systems for over 70 years, proudly unveils their new parallel rack refrigeration system. The new system will maximize energy savings, while minimizing environmental impact, and be available to the foodservice industry summer, 2009.
The parallel rack refrigeration system, often referred to as a “distributed” system, is a multiple compressor refrigeration unit piped in parallel to yield smooth capacity control as compared to a single compressor unit. A parallel system can be located in a back room or on a roof, in close proximity to refrigeration equipment for reduced piping. Master-Bilt’s parallel units use scroll compressors for the most energy efficient and environmentally friendly system. Parallel units, matched to an appropriate condenser, are modular and allow for additional or modification to compressors, as needed.
Some of the parallel rack refrigeration system’s energy saving features include:
- Ability to match refrigeration capacity to actual load, which amounts to a 20% or more savings over a single compressor unit.
- The lead compressor is a digital scroll which better matches capacity needs, and provides a three percent energy saving over standard parallel units.
- Subcooling increases refrigerant efficiency on low temp applications by approximately 17%.
- Optional heat reclaim increases energy efficiency by reclaiming waste heat from the condenser.
- Optional gas defrost increases energy efficiency by using waste heat for defrost.
The standard rack housing and frame is made of durable galvanized steel with stainless steel as an option. A parallel system can be installed indoors or outdoors with a single point electrical connection. Existing on-site evaporators can be used on retrofits, adding another component of savings. The rack system also features an electronic controller that can interface into existing building controls and incorporate HACCP recording to allow monitoring of system features with remote communications possible. Alarm features are built in, and the diagnostic feature reports temperatures, pressures and failure alarms as well as trending of these readings that can be used to predict maintenance needs.
