When the evaporator experiences a load increase what happens to the suction pressure?
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

Why is the Air conditioning not taking hot air out?
Sounds like a problem which involves the evaporator, although the problem may not necessarily be at the evaporator.
Is it possible for the evaporator valve to stick in a 1997 Camaro RS and how hard is it to change?
I am not exactly sure of what you are asking but there is not an evaporator valve. There is an evaporator core that resembles a radiator and there are not any parts that can stick. The only problem they have is leaking. There is an orfice that goes in the inlet to the evaporator and it has no moving parts.It can get stopped up and cause the high side pressure to get higher than normal.
Explain the possible causes about high pressure side is too low and low pressure side is too high?
The high pressure side being too low could be caused by a lack of refrigerant in the system, a malfunctioning compressor, or a problem with the condenser. On the other hand, the low pressure side being too high could be caused by an issue with the expansion valve, a blockage in the refrigerant lines, or a failure in the evaporator coil. It is recommended to have a professional technician diagnose and repair the problem to ensure proper functioning of the system.
Why would the rear air conditioning in a car blow hot while the front blows cold?
The most typical problem is the expansion valve for the rear is bad. another possibilty would be the evaporator in the rear is clogged up but that's not common.
Can you use a 13 seer condensor with a 10 seer coil?
it will work but you will not reach the rated seer rating. also you will have oil return problems due to less refrigerant volume (because the newer 13 seer units run a lower head pressure. this problem can be resolved by installing a thermostatic expansion valve (txv) but when it is all said and done just go to 410-a with both units because r-22 is not going to be reproduced after 2010.
When the high side pressure is low and the low side pressure is high on a residential air conditioning unit what is the problem?
If your low side (evaporator coil) pressure is higher than your high side (condenser coil) while the compressor is running, your switching valve is in the reversed position. That is, you are in the heating mode of the heat-pump, and the pressures are reversed to provide heat into the home.
Why will your ac turn on but not blow cold air?
could have too much freon in it or air is not going thru evaporator If comp runs Check if return line is cold at the comp If it is then you know it is an evaporator problem
Recalls york AC evaporator coil?
Yes there was 2 of them. Both coils were prone to leaks after about a year. Contact your local YORK dealer to see if your evaporator coil model # and serial # are part of the problem coils.
Water temp and elements for hot water heater seem fine. Why is water heater discharging water through pressure valve usually after extended hot water use?
One possible reason for the temperature/pressure (tp) valve to start leaking may be from expansion of the water as it is being heated if there are check valves in the water system this is sometimes the culprit .In most water systems there is plenty of room for expansion in the distribution piping and service line and private well systems have a pressure tank that can absorb the expansion. You may have to add a small expansion tank to the water piping at the heater to solve this problem. hope this helps. Bob
