What is the operating temperature range?
The operating temperature range of an Integrated Low-Temperature Heating Modular Unit depends on its compressor technology, system architecture, and defrosting strategy, especially when designed for harsh winter environments. Aurashu’s integrated low-temperature heating modular units are engineered to maintain stable capacity output even under extreme ambient conditions.

Using enhanced vapor injection (EVI) compressors, high-area heat exchangers, optimized refrigerant distribution, and intelligent vapor–liquid management, the system ensures reliable and efficient performance across a wide temperature span. For heating mode, Aurashu units typically operate effectively from –35°C to +35°C ambient, ensuring consistent heating output in cold climates. In cooling mode, the system generally functions across –10°C to +48°C ambient, supporting applications in both residential and commercial buildings.

The unit maintains stable heating performance under ultra-low temperatures by using multi-stage throttling, intelligent frost prediction, and high-efficiency defrost cycles, reducing energy loss during continuous operation. Heat output is preserved through wide-range inverter control, allowing the system to regulate compressor speed and maintain high COP even when outdoor temperatures drop sharply.

At higher ambient temperatures, Aurashu’s micro-channel heat exchangers and optimized refrigerant circuits improve heat rejection efficiency, protecting the compressor from thermal overload and extending system lifespan. Furthermore, the modular architecture allows multiple units to operate in rotation or cascade mode, ensuring a broader working envelope and operational redundancy.

Overall, the wide operating temperature range ensures that the Integrated Low-Temperature Heating Modular Unit performs reliably in diverse climates—ultra-cold northern regions, temperate zones, or hot environments—making it suitable for district heating, commercial HVAC, industrial processes, and residential comfort applications where year-round stability is essential.
