Danfoss’ thermostatic expansion valves are designed to meet the diverse needs of cooling applications using a variety of refrigerants. These valves are engineered to provide precise control of the injection of liquid refrigerant into evaporators, thereby ensuring the effective operation and protection of the compressor motor from liquid refrigerant. With options for both adjustable and non-adjustable superheat settings and high maximum operating pressure differential (MOPD) values, these valves offer flexibility for different installation requirements. They feature a compact design, can be equipped with an MOP charge to protect against excessive evaporating pressure, and are available in several connection options to facilitate installation across a wide range of refrigeration systems. The Danfoss range of thermostatic expansion valves emphasizes energy efficiency and reliability, maintaining constant superheat levels across varying load conditions.

Frequently Asked Questions

How does the expansion valve work?

An expansion valve regulates the flow of refrigerant into the evaporator. By reducing the pressure, it allows the refrigerant to expand and transition from liquid to vapor, facilitating efficient heat absorption and cooling in the evaporator. This process is essential for the air conditioning system’s heat exchange cycle.

What is the function of the Danfoss expansion valve?

The Danfoss T2/TE2 thermostatic expansion valves are designed for precise refrigerant injection control into evaporators, optimizing performance in food retail refrigeration systems. These valves adjust the flow based on cooling demand, ensuring efficient operation and temperature regulation, vital for maintaining optimal freshness and energy efficiency in refrigerated displays and storage.

What are the two main types of expansion valve?

The two main types of expansion valves are Thermostatic Expansion Valves (TXV) and Automatic Expansion Valves (AXV). TXVs, the most common type, adjust refrigerant flow based on changes in the evaporator’s temperature. AXVs maintain constant pressure in the evaporator, ensuring steady conditions for optimal cooling efficiency. Both types are crucial for managing refrigerant in air conditioning and refrigeration systems, optimizing performance and energy efficiency.
