step 1. Exactly what are the condenser stress and you can condenser temperatures from h2o fridge?
Condensation temperature is the new saturation temperatures out-of refrigerant vapor about condenser within a specific pressure. New condensation weather is not equivalent to heat of one’s cooling medium, and there’s a big difference inside the heat transfer temperatures between them.
Condensing tension is the stress where the newest refrigerant condenses into a drinking water regarding the condenser. As pressure inside condenser regarding the cooling system is also not be mentioned, indeed, pressure miss of refrigerant from the fatigue tubing and regarding condenser is really brief. No matter design debugging or repair, generally thought that the new fatigue pressure is approximately equivalent to the latest condensation tension.
dos.The connection anywhere between condenser temperatures and condenser pressure
Regarding the chart can be seen quite simple, condenser temperatures and you can condenser tension are proportional adjust, condenser stress and also the temperature is corresponding.
step 3. Estimate off condenser heat
For the refrigeration gizmos debugging, we quite often would like to know the new condenser temperature away from drinking water chiller and calculate the latest condenser pressure (ruthless otherwise exhaust pressure), making sure that can judge whether the drinking water fridge method is an effective problem;
In summer, when the air-trained outside ecosystem is around 35 level, we could guess the warmth immediately the fresh new condensation temperatures thirty five + (ten
20 °C)fifty °C, with respect to the temperature and you can tension dining table, you can realize that brand new evaporation pressure at that date is mostly about step 3.05 MPA (absolute pressure, R410A refrigerant) ;
Water Chillers, the Air conditioning Tower could guide a temperature regarding twenty five amount, after that exactly how much is the condenser temperatures of your water chiller?
20)forty °C, according to the temperature and stress dining table, it’s easy to realize that the fresh new condensation tension at this go out are about1.55 MPA (absolute tension, R410 refrigerant)
Using this type of condenser stress, we could build an evaluation into drinking water chiller program higher-tension table, is determine whether the water cooling system is normal, questionable, ultimately, is simply too highest otherwise as well lower, to possess repairs debugging or very beneficial.
4.The relationship between condensing temperatures and you will Stamina out-of Water Fridge
From the t-s visualize, it is visible when the fresh condensing temperature of one’s drinking water fridge system is improved, the power consumed are increased;
Associated with very simple, condenser heat enhanced, regarding evaporation temperatures ongoing, the fresh compressor stress proportion increased, and the stamina of your own compressor try proportional on the tension proportion, that is, the pressure ratio increased, the effectiveness of this new compressor in addition to enhanced.
New compressor compresses 5 kilogram out of refrigerant so you can fifteen kilogram off power; certainly even more strength compared to compressor compresses 5 kilogram out of refrigerant so you’re able to twenty-five kilogram.
5.The connection between condensing heat and you will refrigerating potential
Throughout the t-s picture about cartoon, you can see that the latest condensing temperature develops, the latest cooling capacity of your own program was shorter.
Here to describe how come, due to the increase in condensing temperatures, evoking the refrigerants for each product air conditioning capabilities will be shorter, in identical refrigerant mass flow, the system from air conditioning ability will be smaller.
6.The connection anywhere between temperatures stream and you can evaporation tension
Brand new brief answer is this new condensing side of the load and you will condensing stress matchmaking. Not as much as a stable doing work updates (refrigerant flow), the higher the warmth weight, the better the latest condensation stress, and you will vice versa. We are able to that is amazing after you build the new condenser quick (thermal weight is relatively large), the fresh new refrigeration experience very easy to security the newest questionable.
Many reasons exist on reduced evaporation heat. The reason is that there is certainly quicker refrigerant regarding evaporator or perhaps the throttle valve enjoys a bad throttling feeling
1. Extension Valve solutions are large; 2. Expansion Valve inability or expansion device beginning too big, there is no throttling feeling; 3. The refrigerant charges of your own coolant system isn’t sufficient; 4. The brand new refrigeration program does not have refrigerant
(4) The new condenser disrepair, temperatures transfer body fouling serious, may also bring about higher condensation tension. The existence of scale provides a impact on the brand new condensation stress.
step one. There clearly was more refrigerant on condenser dos. Air conditioning Possibilities have other publications one entertain the condenser temperatures transfer area. 3. The condenser doesn’t condense really
The latest compressor compression proportion increases, the new gasoline alert coefficient reduces, and so the compressor refrigeration potential reduces. Increased stamina practices. Should your fatigue climate is too high, it will increase the usage of compressor lubricating oil, improve oil leaner and you may connect with lube; in the event the deplete temperature www.hookupranking.com/couples-seeking-men is nearby the compressor petroleum thumb section, it’s going to lead to an element of the lubricating petroleum in order to carbonize and you may gather within sucking and release Valve Harbors Affect the sealing element off valve.
1. Lowering the temperature off air conditioning medium can aid in reducing the newest condensation temperatures additionally the condensation tension, but it is hard to favor from the maximum of the surroundings.
dos. Improving the flow speed away from air conditioning medium can reduce this new condensation temperatures a little. However, don’t that-sided improve cooling liquid otherwise air flow, because this increases new cooling water pump or partner and you may system electricity, will likely be an intensive idea.
The greater deplete stress increase the latest compressing really works and you may disappear the latest fuel alert coefficient, that decrease the air conditioning efficiency.
Now, we’ll discuss the condensation experiment on the temperature exchanger experimentpared to the evaporator experiment, the fresh new condenser test is fairly simple. Discover about three controlled variables, below:
Actually, handle this new condenser inlet stress, you might control the latest condensing tension condenser, once the stress get rid of condenser is actually very small, everything as the inlet tension is equal to the newest condensing tension. So just how to manage the new import stress?
1. Control the air volume of the newest flow-owing to condenser. Whether your air volume is actually higher, the condensing pressure will drop
