The uninterrupted power supply system is designed to ensure continuous operation and protection of high-tech equipment in the event of power supply failure or its parameters exceeding permissible limits, thereby ensuring continuity of the Customer’s business.
Uninterruptible Power System Structures
The distributed structure of uninterrupted power supply
However, the system may be limited to:
Centralized structure of uninterrupted power supply
The system may be limited to:
In pure terms, each of the systems reviewed is rarely used. A centralized system is advisable when concentrating equipment that performs a single task and consists of components of the same reliability class and energy consumption characteristics.
A two-tier system, a combination of a centralized and distributed system, is used to optimize investment. Optimizing such a system in terms of capacity and equipment costs is to identify the most responsible users and minimize the number of customer groups by configuring the local area network accordingly.
When selecting a two-tier structure, other than installing a single high-capacity UPS (or a series of parallel UPS), some are protected by a lower-capacity local UPS. The aim is to protect such equipment as file servers, local area network management workstations, communication equipment, and communication systems from power outages due to failures of the cable network inside the building.

The guaranteed power supply system is designed to ensure uninterrupted operation and protection of high-tech equipment in the event of power supply failure or its parameters exceeding permissible limits, thereby ensuring continuity of the Customer’s business.
Load separation by type reduces the load on the Uninterruptible Power Supply (UPS), which in turn increases the battery life of the UPS in an emergency mode and allows the use of less powerful UPSs.
In this case, the UPS conducts a galvanic interchange between computer and communication equipment and the power supply network of process equipment (in particular, the air conditioning system). This makes it possible to significantly reduce the level of interference in the protected power supply network when switching on and off equipment characterized by a non-linear type and large starting values of current consumption.
Electrical load types
Modern high-tech computing and telecommunication equipment are sensitive to minor environmental changes. Therefore, maintaining strictly defined temperature and humidity levels is a prerequisite for regular operation. The air-conditioning system for such facilities should be of high reliability and ensure that the room's optimum temperature, humidity, and cleanliness are maintained at all times. This is especially true for data centers, without which it is impossible to imagine a modern business.
Industrial Air Conditioning System (from now on, SPC) is intended for the maintenance of required parameters of the microclimate of IT equipment of data processing centers, communication operators' nodes, centers of Internet service providers, hosting centers, various television- and radio transmission stations and other information technology facilitie
The main source of cold for all types of IACS can be either a freon system with direct cooling and a remote condenser, or a chiller (liquid) cooling system.
The type and composition of the SPC are determined at the stage of development of the technical solution, taking into account the capacity of the cooling equipment, requirements for reliability, efficiency, scalability, and controllability of the system, design and technological constraints, investment volumes, and implementation time. When choosing equipment, preference is given to innovative developments of leading manufacturers of climatic equipment, providing energy-efficient cooling of IT equipment.
Industrial air conditioning system architecture
Room-level cooling involves one or more parallel precision air-conditioning systems that not only cool the equipment but also act as a large mixer, mixing the air in the room to give it a uniform average temperature and prevent local overheating zones.
In the architecture of the cooling system at the level of a series of air conditioners feed cold air into the space between the rows. The equipment is located on the principle of a «hot/cold» corridor, which makes the air circulation predictable and allows you to use all the nominal cooling capacity of the air conditioning system.
When cooling at the rack level, the air-conditioning units are structurally connected to the rack, which initially implies a high density of placement and power of IS equipment. The air circulation paths in this architecture are clearly defined and do not depend on the room's characteristics. This cooling method allows equipment with a total consumption of more than 30 kW to be deployed in one rack.
Innovative solutions and solutions from leading climatic technology manufacturers - Emerson Network Power, Rittal, APC by Schneider Electric, Stulz - are used in developing the industrial air-conditioning system for efficient IT cooling equipment ranging from a few kilowatts to several megawatts.
The Data Center Engineering Infrastructure Monitoring and Management System is a software and hardware system designed to remotely collect information on the status of equipment of various subsystems as well as environmental parameters (temperature, humidity, smoke), with the purpose of prompt response in case of emergencies (fire, accident, intrusion by unauthorized. users)
The use of the monitoring and control system helps to eliminate problems related to the maintenance of the engineering infrastructure of the data center, increases the reliability of equipment operation, and reduces the reaction time to an event.
The application of the monitoring and control system dramatically simplifies the process of administrating the engineering systems of the data processing center, allowing the rapid receipt of the information on the status of all systems at the moment in time.
