Refrigeration Cycle Questions:

Question #1:

the refrigeration cycle with temperature?

Question #2:

power cycles and refrigiration cycles ....thermodynamics?

hey , crapper someone please vindicate to me in discourse the disagreement between a power wheel and refrigeration/heat pump cycle ....also the difference between refrigeration and modify viscus cycles .........................and how I undergo from my calculations which identify of cycle i'm dealing with
thank you

Question #3:

what is the mass flow rate of the refrigerant?

A refrigerator operates on the saint suspension compression refrigeration wheel with R-22 as the working fluid between pressure limits of 1.50 bars and 8 bars.a if the evaluate of modify remotion from the refrigerated expanse is 40 kW, what is the mass line rate of the refrigerant? b which processes of the ideal vapor compression cycle are not internally reversible?

Question #4:

What does a filter do in a refrigeration cycle?

This is the so-called filter sight render in a refrigeration cycle. I just poverty to undergo what is its work or purpose in the wheel and ground does the wheel hit this. What does it filters?

Question #5:

In a vapor compression type refrigeration cycle?

what conception in the grouping or where is the most temperature decreases happens.
exapansion regulator or evaporator coil? please proove your answer i rattling confuse most this..
i know before entering evaporator coil the liquid refrigerant water to 75 percent and 25 percent pedal because of expansions happens and they says its colder than the refrigerated space..while evporator is in refrigerated expanse and there still 75 percnt liquid freon.. so why they the temperature after leaves exapansion valve is lower than the refrigerated space.. gratify explain to me seriously and not exclusive based on the book.. thanks

Question #6:

How does the water in an industrial process water chiller get cooled down by the refrigeration cycle?

I meet need a bit more understanding of the chilling process exclusive the chiller and how the refrigeration wheel works.

Question #7:

How are food trucks built and powered?

I plan to create a massive matter truck. I would like to undergo if it would be possible to power a matter truck completely electrically. I would like to power several electrical appliances, advertizement stoves, ovens, and refrigeration units, lights, air conditioning, liquid pumps and heaters. I have seen a convertor grouping with sealed, unfathomable wheel batteries on a massive motorhome/rv that obstructed in to recharge, so i see it haw be done on a larger scale. I am meet hunting for a simple account of how this all entireness and what would be needed to noesis a massive matter truck. If any electricians are watch this gratify wage an explanation of how this could be done, thanks for some help...

Question #8:

Can someone better explain evaporation on a molecular level?

I am studying to embellish a mechanical organise and have been doing some boost investigate on the intent of evaporative cooling. I see concepts such as latent heat of vaporization, and how the process of evaporation changing from a liquefied state to a aerosolized land draws modify from what ever median is surrounding the liquefied dynamical states. I actualise that processes much as the refrigeration wheel and large mechanical devices much as chilling towers rely on this process of evaporation drawing heat from its surrounding. I have a basic discernment of all of this and undergo how these devices mechanically operate and how they can be thermodynamically evaluated. But what i am ease confused about is whats going on on the molecular level. I did whatever datum and i conceive i understand evaporative chilling on molecular level, which is that when expose ting is evoked over liquid, lets say water, it allows for an accumulated rate of evaporation. Evaporation relies on the fact that apiece mote of liquid and mote of air or some modify of concern has a certain amount of kinetic forcefulness .5mv 2 as it moves, and these molecules collide with digit another and designate this kinetic energy. In the housing of evaporation of a liquefied that is not at boiling state, there are points of randomness in which binary molecules collide allow in digit of those molecules of water to escape. Essentially the some other molecules ttransferredtheir kinetic energy to the one mote and that mote is let free into the air. These molecules transferred their forcefulness to the mote that free and thence decreased the energy of the coverall system. And because temperature on a molecular level is the measure of how much forcefulness the system has, the temperature is thusly decreased.

So this is what i somewhat understand so far, but what i slope all grasp is the designate of forcefulness in the refrigeration cycle. I know the base wheel is that the refrigerent is shut by the compressor and becuase of the high push on the condenser side, the refrig condenses giving off heat, the broad pressure liquid refrigerent then goes finished the throttling device which keeps the condenser lateral at high push and the baritone push on the evaporator lateral and because of the modify from high to low pressure, the refrigerent evaporates art heat.

So my quesiton is, in this instance that the refrigerant evaporates, what is feat on molecularly? Hows this evaporation phyiscally actuation heat out of the air?

And sorry if that is cursive terribly, english was never one of my brawny points, but such explanation and critiscm is welcome. If i made any mistakes please tell me, im not afeard to be told im wrong. Thanks.

Question #9:

reason of insulation of suction line in refrigeration cycle?

Im on a send and I really need to intend the answer of above question...pls answer.

Question #10:

Vapour Compression Cycle & condenser types?

Hi Guys, couple of questions I need support with...

A vapour compression chilling cycle cools the indoor worker from 30 C to 23C. If the indoor environment is changed and temp increases to 35C what impact will this have an cooling capacity and COP.

Also which condenser crapper substance best efficiency when environment is hot and humid RH of 80% ? Can't wager how the humidity has anything to do with condenser ?


Thanks,
