THE FIRST INSIGHTS
Energy Efficiency is a theme in today’s innovations. In the past, the focus would be on performance, practicality & aesthetic design, due to the low cost of electricity & past consumer trends.
Today’s Supermarket owner however, will go the extra distance and invest in products that will have low running costs, low maintenance needs and long lasting lives, and rightly so. With the increasingly high electricity prices all over the world, energy saving is now a crucial factor in the design of any enterprise. Our latest innovation the
DC‐Inverter system is specifically designed to save as much energy as possible to the supermarket owner.
WHAT IS THE INVERTER TECHNOLOGY IN REFRIGERATORS?
The Inverter technology (DC) is the latest evolution of technology concerning the electro motors of the compressors. An Inverter is used to control the speed of the compressor motor, so as to continuously regulate the temperature of cabinets. The DC Inverter units have a variable‐frequency drive that comprises an adjustable electrical inverter to control the speed of the electromotor, which means the compressor and the cooling output. The drive converts the incoming AC current to DC and then through a modulation in an electrical inverter produces current of desired frequency. A microcontroller can sample each cabinet air temperature and adjust accordingly the speed of the compressor.
ABDIN DC INVERTED CONDENSING UNIT AND CENTRALIZED COOLING SYSTEM
Our DC inverted refrigeration system can be implemented with various refrigerants that have proven to be among the most effective as of time being: R‐404A,
R‐290 (propane), R‐744 (CO2).
ABDIN DC inverter system is based on specialized scroll compressor developed by Mitsubishi
(Japan) exclusively to be used in our refrigeration.
The system main components are the BLDC
(Brushless DC compressor) variable speed compressor and electronic expansion valves for precise oil & liquid injection. A BLDC compressor is very energy efficient compared to any other type of compressor, due to its very wide range of cooling capacity modulation, and continuous adjustment of the compressor’s speed according to real‐time cooling demand.
The real‐time constant monitoring of each cabinet connected to the unit allows the continuous adjustment of the suction pressure set point, in addition to keeping the ON‐
OFF cycles to a minimum, reducing the high spikes of energy consumption. The use of electronic expansion valves ensures controlling the flow of refrigerant entering a direct expansion evaporator and that only the required amount of oil is injected in the compressor for lubrication. This allows the system always to operate optimally by constantly modulating the valve opening.
BENEFFICIAL EFFECTS OF DC INVERTER TECHNOLOGY
If compared with a standard conventional system, DC inverter technology results in noticeable advantages :
Faster response to changes in the weather conditions
Improved maintenance of design conditions with less temperature fluctuation
Significant reduction in the operating costs (40‐60% less)
Temperature set‐points are achieved at a faster rate
Lower noise levels in the area surrounding the unit
Eliminates voltage peaks from compressor, therefore reducing its strain & improves its life
