High voltage frequency converter can realize energy saving and speed regulation in central heating project

High voltage frequency converter plays the role of energy saving speed regulation in central heating projects. The following is the actual application case of Aodong Electric, through which the product high voltage frequency converter is introduced how to work and how to give full play to various performance to achieve the purpose of energy saving speed regulation.

Project status:

A large-scale centralized heating project in Chayouqian Banner, Ulanqab City, Mongolia, was equipped with three domestically produced 10kV 630kW circulating water pumps from a well-known brand. Initially, the project lacked matching high-voltage frequency converters and failed to install soft starters and energy-saving speed regulation equipment during preparation for operation. The local power supply company recommended adding these devices to ensure safe startup and variable frequency speed control, which would achieve both energy-saving effects and grid quality assurance—a win-win solution. After comparing multiple suppliers based on comprehensive capabilities and cost-effectiveness, the client ultimately chose Xiangyang Aodong brand high-voltage frequency converters (single-drive, manual bypass).

Local Climate: Chahar Right Front Banner experiences a cold, arid climate with frequent winds and scarce rainfall, characterized by significant day-night temperature variations. The region belongs to the northern temperate continental arid climate zone. Winters last up to five months, with an average annual temperature of 4.5°°C. The highest recorded temperature reached 39.7°°C (recorded on May 22,1965), while the lowest was-34.4°°C. Annual precipitation totals 376.1㎜ mm, predominantly concentrated in July to early August. The frost-free period averages 131 days annually, with early frosts typically appearing around September 10th. Late frosts (varying by mountainous and coastal climate zones) occur between March 23rd and May 30th. Westerly winds prevail in most areas.
