An expansion valve is a device that is used to control the flow of refrigerant in a refrigeration or air conditioning system. It is designed to maintain a constant superheat of the refrigerant at the outlet of the evaporator, which helps to improve the efficiency of the system.
There are a number of accessories that may be used in conjunction with an expansion valve, including:
Sensing bulbs: These are small, flexible tubes that are attached to the expansion valve and contain a small amount of refrigerant. The expansion valve uses the temperature and pressure of the refrigerant in the sensing bulb to determine the flow of refrigerant through the valve.
Capillary tubes: These are small, narrow tubes that are used to restrict the flow of refrigerant through the expansion valve. The length and diameter of the capillary tube can be adjusted to fine-tune the flow of refrigerant through the valve.
Solenoid valves: These are electrically-controlled valves that can be used to open or close the flow of refrigerant through the expansion valve. They are often used in systems that have multiple evaporators or that require precise control of the refrigerant flow.
Filter-driers: These are devices that are installed in the refrigerant lines to remove moisture and contaminants from the refrigerant. They are typically used in conjunction with an expansion valve to help protect the valve and other components in the system.
