The expansion valve reduces the pressure and temperature of the refrigerant as it passes, allowing it to turn into a cool, low-pressure liquid. Now, the compound can absorb heat effectively when it's in the evaporator.
15 Δεκ 2017 · A thermostatic expansion valve (TXV) (see Figure 1) is a refrigeration and air conditioning throttling device that controls the amount of refrigerant liquid injected into a system’s evaporator—based on the evaporator outlet temperature and pressure—called the superheat.
What Does the Thermostatic Expansion Valve Do? The TXV is a modulating valve that controls the flow of refrigerant into the evaporating coils. This keeps the system running as efficiently as possible and prevents liquid refrigerant from getting into the compressor, potentially causing a breakdown.
When hot air enters the AC unit, the refrigerant absorbs it, increasing its pressure. By regulating the refrigerant flow, the expansion valve facilitates the conversion of high-pressure liquid refrigerant to low-pressure liquid, promoting efficient heat transfer.
How Does an Expansion Valve Work in an Air Conditioner? The best way to understand the purpose of an expansion valve is by understanding how the refrigerant inside the system works as well. Most AC models function with the use of refrigerant that runs through piping.
25 Μαΐ 2024 · How Do Expansion Tanks Work? The primary function of an expansion tank is to compensate for the increase in volume and associated pressure rise in a system’s fluid due to temperature changes. As the temperature of the fluid increases, its volume expands.
Direct expansion, or DX cooling, uses the principles of thermodynamics to transfer heat from one area to another through the evaporation and condensation of a refrigerant, which serves as the medium through which heat is captured and removed from one area and released in another.
