So, the role of expansion valve is very important in providing smooth and efficient performance from your HVAC system. Small but mighty, and it is in charge of controlling the flow of refrigerant throughout your system-thus affecting overall performance. There are many expansion valves in the market so it is necessary to have a basic overview of each option that will help you select which suits well for your HVAC equipment.
Thermostatic Valve- Common type of expansion valve used in HVAC SystemsElectronic Expansion Valve - Non-spring Loaded Mechanical Device That Showers RefrigerantDirect Thermal Type Of... Although the first type of valve in this list, manual valves are now nearly obsolete in present-day systems but you will be encountered with the other three types anywhere.
Thermostatic Expansion Valves (TXVs): Of the various categories, TXV is most commonly used in HVAC systems. They do this, through modulation of the refrigerant flow in response to superheat level, thus consistently controlling and delivering a setpoint temperature.
Electronic Expansion Valves (EEVs): The Electronic expansion valve works with precision and adapts to electronic signals from the microcontroller in an HVAC. They are well-suited to systems of larger complexity requiring refrigerant control over more than one loop.
the mechanical expansion valves or the thermal expansion valve (TEVs); they rely on simple mechanics to regulate reseeding of refrigerant and are ideal for smaller HVAC applications.
And if particulates (AKA dirt or other debris) get caught in the expansion valve, it can cause several problems including reduced cooling capacity, higher noise levels and poorer efficiency. Deploy best practices for regularly maintaining and cleaning oversight.
When dealing with expansion valve problems, the first thing you must do is make sure that this valve opens and permits free flow of refrigerant. The functioning of the valve can be verified by checking superheat level with a temperature sensor.
