THERMAL EXPANSION VALVE VS. CAPILLARY TUBE FOR ELECTRICAL ENCLOSURE AIR CONDITIONERS



Enclosure air conditioners are important for protecting electrical components from heat and humidity. To help maintain a suitable temperature in the enclosure, air conditioners circulate refrigerant from a compressor through a condenser and an evaporator and back to the compressor.Get more news about Shrinkless Expanding Machine,you can vist our website!

The refrigerant arrives in the compressor as a cool gas, which is then compressed to a high-pressure gas that is passed on to the condenser. In the condenser, the gas is converted to a liquid that then flows through to the evaporator. As the liquid evaporates back into a gas to continue the cycle, it draws heat from the surrounding air in the enclosure, which has the effect of lowering the temperature.
Optimal refrigerant flow is clearly a critical component of any air conditioner. The flow of refrigerant into the evaporator is controlled with an expansion device, which can either be a passive capillary tube or an active thermal expansion valve.

Although these two systems both control the flow of refrigerant, they work in different ways. A thermal expansion valve can respond to the environment by increasing or decreasing the flow of refrigerant as necessary, while a capillary tube is a fixed system that does not fluctuate with heat load changes.
Better efficiency – As temperatures fluctuate over time, a thermal expansion valve can adjust the refrigerant flow to accommodate a larger or smaller heat load. This allows the unit to operate more efficiently.
Broader temperature range – When the ambient temperature increases, the cooling system has to work harder. A thermal expansion valve can increase the flow of refrigerant to provide better cooling at higher temperatures. This flexibility also prevents liquid slugging, which can damage compressors.
Larger refrigerant charge range – Having the right refrigerant charge is important for optimal performance, especially when the system uses capillary tubes. Thermal expansion valves allow for a greater variation in refrigerant charge without impacting performance.
