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

Equalizing lines should be located in multiple condenser and compressor applications where Between condenser and evaporator coils or Near the TXV or Between compressors and condensers or None of them?
oppisite side of txv sensing bulb on outlet of evaporator (suction line)
Will the Evaporator Pressor Regulating valve close if the Thermostatic Expansion Valve is in the evaporator air stream?
The EPR valve should work reguardless of if the TXV is in the air stream. The TXV in the airflow shouldn't make it act any different since it is sensing the temperature at the bulb instead of at the valve it's self.
Effect of moisture on thermostatic expansion valve?
None, a TXV operates by it's sensing bulb sensing superheat of the suction line as it exits the evaporator coil.
What will happen to power delivered by solar cell do when resistance of he load is increased?
A: Nothing will happen if the load increases or even removed the voltage will go to the open voltage condition no harm.
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
