I recently installed a surge protector to the disconnect for the condenser of my straight air-conditioner. I installed the surge protector to the disconnect for my condenser in exactly the way that the instructions with the surge protector instructed me to install the surge protector. I don't...

When I was looking at the list of related threads to my thread "How does metering device in an A/C cause flash gas", I noticed an interesting thread titled "How does low charge on an A/C cause the subcooling to be low". PeterDonis and fourthindiana had an interesting conversation on that...

Hi! I'm a bit curious, what would happen if there would be a leakage in the condenser in a nuclear plant (PWR or BWR). As I understood it the stean in the turbine is expanded to about 4 kPa and I guess the pressure outside in the freshwater that is pumped into the condenser is at atmospheric...

Hi, I have an attempt at a plate heat exchanger (condenser) that uses water to condenser refrigerant, as a part of a heat pump. I have a total heat load of 12.01 kW. My current heat load is 10 kW. I have an analytical error on the wall temperature of about 23%, if I use Excel's Solver to...

I used to attend an HVAC program at a trade school. One time my instructor and i were working on either the outdoor unit of a split-system heat pump or the condenser of a split-system straight air-conditioner. Even though the unit we were working on was either an "outdoor unit" of a heat pump or...

Preface to thread: The multimeter is set to read resistance in all the scenarios I ask about in this message. The word "COMP" in the ladder diagram stands for compressor motor. The three letters underneath the capacitor are DRC, which stands for Dual Run Capacitor...

So, a few days ago I was beetling down the road, and out of nowhere, the engine started all kinds of unacceptable tomfoolery: spluttering, loss of power, misfiring, hesitation, refusal to accelerate. I pulled over and fiddled with various things for an hour or so, and ended up with it running...

If the distance between the plates of a parallel condensor is 4mm and the potential difference is 60 volts . Now if we increase the distance between the plates to 12mm , then Why the electric field does not get decrease , instead of that potential difference between the condensor becomes 180...

Hi, So when you over-excite the rotor of a synchronous motor, or under-excite the rotor of a synchronous generator, how is the flux actually changing the power factor of the armature to leading? (something to do with the magnitude of the armature reaction flux vector?) That is to ask: by what...

Hi All, Is there a list of thermodynamics equations regarding the chiller process from condenser, evaporator, compressor to the regulator. Say I have chiller load at 90%, what set of equations could I use to determine the supply temperature of chill water and condenser supply temperature to...

Having trouble at a plant where the vacuum has increased to the point where a pump has been put on the end of the air ejector condenser to maintain vacuum, without it the limits would be too high and trip the Steam Turbine. The question is, does the air ejector condenser continuously drain...

Hi guys, first post on the physics forum! I am slightly confused by the information provided by the following resource, the website is as follows - http://www.learnthermo.com/T1-tutorial/ch09/lesson-B/pg09.php The point that I do not understand is - "For starters, the quality of the turbine...

Hi! For our class project, we have to design a system that freezes an amount of water as quick as possible. The refrigerant is R134a. The compressor is known. I don't really know how to get started here. How do I choose the evaporator pressure and the superheating, and equally the condensor...

I've noticed that a FEW of the electrical vehicles have no front grill. I am quite surprised that they do not have one, because the condenser of the AC unit needs to have heat taken away from it (in other words, the condenser needs a heat exchanger). So, in view of the fact that E-vehicles don't...

Homework Statement A gas stream contains 18.0 mole % hexane and the remainder nitrogen. The stream flows to a condenser, where its temperature is reduced and some of the hexane is liquefied. The hexane mole fraction in the gas stream leaving the condenser is 0.05. Liquid hexane condensate is...

Hello everyone. I indeed like to understand the things I am learning, and for the love of me, I cannot understand why, according to the formula, capacity of a condenser in a circuit consisted of said condenser and a power source is inversely proportional to the power source's voltage. Could you...

Hi, I am looking to illuminate a quadrant photo diode using a condenser/ lens combination in a optical trap setup. I see thorlabs has a kit that has a 100x objective as a trap and a 10x objective as a condenser. Does that mean that one doesn't need to collect all the laser light scattered from a...

So the starter capacitor in my AC condenser exploded a couple of days ago. I'm headed out to get a new one (found someone open!) and I'm just concerned that the failure could be just a symptom of a bigger problem like a bad compressor or fan motor (its a dual capacity capacitor that serves...

If a condenser were to lose its supply of cooling water and no trips were activated how could you calculate when the vacuum would be lost? i.e. calculate the length of time before no more steam could be accepted by the condenser.

I am trying to follow a guide that I found online and it requires an eletret condenser microphone...which no one seems to carry (my electronics shop, Fry's Radio-shack). I am still a started level guy so I really don't know what to look for when it comes to microphones so I was hoping one of...

In a typical full-sized home AC system [central air] is there a problem with oversizing the condenser? In particular, the idea is to add a pre-cooler just before [above] the condenser. This would provide additional cooling as well as increasing the volume of the system. I tend to assume that...

Hey, I am trying to determine the importantance and difference of fouling in sizing the evaporator and condenser in a Refrigeration cycle? Thanks, Alexisonsmith

I read about refrigerators and often a fridge has two components: 1. compressor 2. condenser The compressor compresses the vapor - what does it actually do? does it increase the temperature of the vapor? The condenser condenses the vapor into liquid and then the liquid is expanded...

Hi I am a physics teacher but I studied theoretical physics so I am not very good in experimental physics. Recently, I burnt a condenser but I have no idea why. I tried to charge it with about 10 volts. His capacity was 1000 microF and there was written 25 volts on it so what did I wrong...
