Following the workshop tour, Zhang Hengshuo took the delegation to the meeting room. Together with Zheng Haiqing, Founder and General Manager of the Group, they discussed the design scheme of the new‑energy central air‑conditioning system for Dingsheng’s production workshops.

Dingsheng currently operates 10 workshops on its site served by 1,000 cabinet air‑conditioning units. These units require frequent replacement and incur substantial maintenance costs. Based on the site layout, six workshops can be divided into two zones served by two separate air‑conditioning systems.。

We proposed two schemes for a centralised new‑energy air‑conditioning system. The first option uses integrated energy tower units. This unit integrates conventional heat exchangers, cooling towers, circulating water pumps, water tanks and connecting pipework. It features a long service life and low running costs, delivering roughly 30% energy saving compared with the existing air‑conditioning setup. The alternative scheme adopts containerised integrated centrifugal chillers paired with energy tower heat pump units for even higher energy efficiency.

Once retrofitted, the system enables centralised management and labour savings, with low maintenance and operating expenditure to cut production costs and improve overall efficiency.

After intensive discussions, the two sides reached further consensus on the project. The Dingsheng team spoke highly of Halidom’s technical capability and tailored solutions after the visit, which paves the way for potential co‑operation.
