Danfoss has introduced the AXV valve platform, a new mechanical pressure regulator designed to deliver consistent performance, simplified system integration, and lower overall costs for cooling and refrigeration applications. The platform is developed to support both hot gas bypass and liquid injection functions, offering flexibility for original equipment manufacturers (OEMs) and system designers.
The AXV platform is engineered to regulate evaporator pressure directly, enabling stable evaporation temperatures across the full surface of the evaporator. This approach enhances system reliability and performance compared to conventional superheat-based regulation methods. As a result, the solution is well-suited for applications including air dryers, water chillers, ice cream machines, and frozen beverage dispensers, where precise temperature control is critical.
The product range includes two configurations: AXV-H and AXV-I. The AXV-H variant is designed for hot gas bypass applications, maintaining compressor suction pressure by introducing hot gas and adjusting capacity in response to load conditions. The AXV-I variant is tailored for liquid injection, controlling refrigerant flow based on evaporator pressure to maintain a defined operating setpoint.
Constructed with a stainless-steel body and incorporating laser-welded double diaphragm technology, the AXV platform is built for durability and long operational life. The design ensures accurate pressure regulation with minimal internal friction, contributing to stable and efficient system performance over time.
The valve operates across a broad temperature range, from -40°C to 140°C, and supports compatibility with multiple refrigerants, including A1, A2L, and A3 classifications. This wide compatibility makes it suitable for a variety of modern HVACR systems and evolving regulatory requirements.
A key feature of the AXV platform is its simplified installation process. The design eliminates the need for external sensing elements, reducing system complexity and installation time. This contributes to lower applied costs while maintaining high performance standards.
With the introduction of the AXV platform, Danfoss aims to provide a reliable and adaptable solution for precise pressure control, supporting the evolving needs of the global refrigeration and air conditioning industry.
