When the load on the evaporator increases the TXV?

when the load increases the amount of vapor increases , so the pressure inside the evaporator increases and as we r in the wet region inside the evaporator the pressure and the temp. are proportional so the temp. too will increase

but we use some valves to fix this problem , for example thermostatic expansion valve

it helps add more m dot of the refrigerant so the amount of heat from the load will be distributed over a larger mass so the pressure inside the evaporator will remain the same
