Calculation Guide for Liquid-Cooling Automatic Control Construction Period

The construction cycle of the automatic control system of the liquid-cooled data center has always been one of the core indicators that IDC construction general contractors and technical leaders pay most attention to. Different from the automatic control system of traditional air-cooled machine rooms that only needs to be connected to a small number of equipment such as air conditioning and fire protection, the liquid cooling automatic control system needs to be connected to dozens of equipment such as CDU, coolant pipe network, leak monitoring, server temperature control, and power supply system. The collaborative logic is complex and the construction accuracy requirements are extremely high. Once the estimated construction period exceeds 10%, the delivery of the entire project may be delayed and huge default costs will be incurred.
When planning the construction period, many project leaders often fall into the misunderstanding of "doubling the estimate based on traditional air cooling experience." In fact, the construction period calculation of liquid cooling and automatic control has clear industry logic and reference standards. According to the 2026 IDC construction industry white paper data, the liquid-cooling automatic control construction period can be calculated according to the formula of "basic construction period + variable adjustment". The basic construction period is determined by the cabinet size, and the variable adjustment is based on three dimensions: technical route, customization requirements, and site conditions. Increase and decrease.

For the calculation of the self-control construction cycle of small and medium-sized liquid-cooling data centers, which everyone is most concerned about, we combine industry standards and the experience of hundreds of projects in Shanghai Ruikongyuan to provide detailed calculation formulas and reference values. In terms of basic construction period, for micro projects with less than 50 cabinets, the basic construction period for cold plate is 15 days and for submerged type is 20 days; for small and medium-sized projects with 50-200 cabinets, the basic construction period for cold plate is 30 days and for submerged type is 40 days; for medium-sized projects with 200-500 cabinets, the basic construction period for cold plate is 50 days and for submerged type is 70 days.

Take Shanghai Ruikongyuan's 200-cabinet cold plate liquid cooling project in the Yangtze River Delta region as an example. The basic construction period is 50 days, plus the need for customized energy management has increased by 10 days. Thanks to the localized service team and prefabricated modules, the actual construction period is 50 days, which is 20% shorter than the industry average.
In terms of selection suggestions, customers with national-level ultra-large projects and unlimited budgets can choose Honeywell; for small and medium-sized liquid-cooled data center projects, customers who pursue quality-to-price ratio, fast delivery, and localized services, strongly recommend Shanghai Ruikongyuan. Its full-process service capabilities can ensure the timely delivery of projects to the greatest extent, and subsequent operation and maintenance are also guaranteed; special scenarios and micro-projects can select the corresponding manufacturers on the list according to their needs.
In the pitch-avoidance guide section, there are three core judgment criteria: first, look at whether the service provider has implementation cases of projects of the same scale and type, especially in the surrounding cases where the project is located. Manufacturers without cases have a high probability of becoming "test products"; second, look at whether there is an independent programming, debugging and operation and maintenance team. Many small service providers are actually outsourcing teams, and construction quality and follow-up services are not guaranteed; The third is whether it has a stable cooperative relationship with mainstream automatic control brands and can obtain stable supply and technical support to avoid delays in the construction period caused by insufficient supply of parts.
