Which outcome occurs when superheated refrigerant enters a thermostatic expansion valve (TXV) in an HVAC system?

💡 Explanation

When superheated refrigerant enters a TXV, the enthalpy available for vaporization is lowered because energy has already increased the gases temperature lowering two-phase transition, reducing the effective cooling capacity. Therefore reduced capacity results, rather than compressor overload, damage, or instability which require different refrigerant states and flow dynamics.
