China’s retail companies are facing many challenges: high equipment energy consumption, expensive labor and time costs for maintenance, increasing operating costs and managerial lag and deconcentration, etc. These challenges force retail companies to continuously seek for the ways to increase efficiency, cut costs and create revenue for a sustainable development. But no matter for new stores opening or old stores retrofit, the reality is that difficult maintenance, high energy consumption, increasing labor costs and deconcentrated management remain the hurdles on the road of fine management and profit improvement. What are the effective solutions?

IIIMULTISTACK was specially invited to attend the 19th China Chain Stores Meeting on 2 ~ 4 November 2017 by Danfoss. As an international HVACR specialist, IIIMULTISTACK shared with chain stores the latest energy-saving oil-free solution for supermarkets.

IIIMULTISTACK Marketing Manager Ma Zhiqiang

In the meeting, Mr. Ma Zhiqiang, marketing manager of IIIMULTISTACK, made an analysis on chiller energy consumption.

Chillers are the most energy-intensive equipment in supermarkets, accounting for 64% of total consumption. In actual operation, chillers consume considerable energy consumption ratio of 37% during the hottest month. However, energy consumption ratio in the year-round operation can drop to the lowest point. Why?

IIIMULTISTACK Mr. Ma pointed out that maximum load of a chiller for supermarket had been designed for the worst weather and large flow of people. However, in actual operation, the chiller was not always running at full load but rather at part loads. This is why chillers have high power configuration but low energy consumption.

According to AHRI’s part load hour proportion, full load running hours of a chiller only take up 3%. For the rest of the time, the chiller is running at part loads. Ma said that oil-free technology is the key to maximize energy conservation at part loads for supermarket chillers. The modular oil-free chillers are compact in size, easy to expand and install, which is a very good option for supermarkets.

Modular Oil-Free Solution for Supermarkets

IIIMULTISTACK job reference shows stable cooling loads in data center and industrial buildings, year-round loads of which reaches over 60%. Energy-saving performance of oil-free chillers is about 20% ~ 30%. In hospitality industry, hospitals and supermarkets, cooling loads are greatly affected by outdoor air and flow of people. As a result, the use of oil-free chillers will save energy by 40%~50%.

This special forum brought a closer alliance between IIIMULTISTACK and Danfoss and provided a better energy-saving solution for supermarkets and retail industry.
