step 1. Exactly what are the condenser pressure and condenser temperatures out of liquids fridge?
Condensation temperature is the new saturation heat out of refrigerant vapor in the condenser from the a particular pressure. The condensation climate is maybe not equal to the heat of the cooling typical, and there’s a positive change inside temperatures transfer heat between them.
Condensing pressure ’s the stress at which new refrigerant condenses with the a liquids regarding condenser. Given that pressure into the condenser regarding cooling system normally not be counted, indeed, the stress drop of your own refrigerant about deplete tubing and you can from the condenser is really quick. It doesn’t matter build debugging or fix, essentially believed that new deplete stress is roughly equivalent to new condensation tension.
2.The relationship ranging from condenser temperatures and you will condenser pressure
On graph can be seen very simple, condenser heat and you will condenser tension is proportional to change, condenser stress therefore the weather is corresponding.
3. Estimate regarding condenser heat
Inside refrigeration gizmos debugging, we often wish to know new condenser temperatures off h2o chiller and you can determine new condenser pressure (ruthless otherwise deplete stress), so that is also legal perhaps the liquid fridge method is a beneficial problem;
During the summer, in the event that air-conditioned outdoor environment is around thirty five grade, we are able to guess heat today brand new condensation heat 35 + (10
20 °C)fifty °C, depending on the heat and you will stress table, it is possible to find the fresh evaporation pressure at this time means 3.05 MPA (absolute stress, R410A refrigerant) ;
Liquid Chillers, the brand new Air conditioning Tower is recognized to guide a fever away from twenty five grade, following how much cash is the condenser temperature of one’s water chiller?
20)40 °C, depending on the temperature and you may pressure desk, you can discover the newest condensation pressure at this big date is actually about1.55 MPA (natural stress, R410 refrigerant)
With this specific condenser tension, we could generate an assessment towards liquids fridge system large-stress dining table, is also determine whether water coolant system is common, high-pressure, fundamentally, is just too highest otherwise too reduced, to have repairs debugging otherwise quite beneficial.
cuatro.The relationship between condensing heat and you can Stamina out-of Liquid Chiller
Regarding t-s picture, it is noticeable when this new condensing heat of the liquid chiller experience increased, the benefit consumed is increased;
The reason is very easy, condenser temperatures improved, in the evaporation temperatures lingering, the compressor stress proportion increased, as well as the electricity of your own compressor try proportional to your tension ratio, that is, pressure ratio enhanced, the effectiveness of brand new compressor and improved.
The latest compressor compresses 5 kg regarding refrigerant so you’re able to 15 kilogram of power; indeed much more fuel compared to the compressor compresses 5 kilogram out of refrigerant so you can twenty five kg.
5.The relationship between condensing temperature and you may refrigerating ability
Throughout the t-s visualize regarding the animation, it is possible to see that the fresh new condensing temperature grows, the newest cooling ability of program was shorter.
Here to spell it out how come, considering the upsurge in condensing heat, inducing the refrigerants for every single unit cooling skill was reduced, in identical refrigerant mass disperse, the machine away from air conditioning strength might possibly be reduced.
6.The relationship ranging from temperatures stream and you may evaporation tension
The fresh short answer is the condensing region of the weight and you may condensing tension matchmaking. Lower than a steady working standing (refrigerant flow), the better the heat load, the higher the newest condensation tension, and the other way around. We are able to suppose when you design the new condenser brief (thermal stream is fairly higher), new refrigeration experience an easy task to alarm the newest questionable.
Many reasons exist toward lower evaporation temperatures. The reason is that you will find shorter refrigerant regarding evaporator or perhaps the throttle device possess an adverse throttling effect
1. Expansion Device alternatives is actually large; 2. Expansion Valve incapacity otherwise extension valve opening too-big, there isn’t any throttling impression; step 3. The latest refrigerant fees of your coolant system is not enough; 4. The fresh new refrigeration system lacks refrigerant
(4) New condenser disrepair, heat import surface fouling severe, also can produce highest condensation tension. The existence of measure possess a influence on the brand new condensation pressure.
1. You will find much more refrigerant in the condenser dos. Cooling Possibilities have most other publications you to definitely reside new condenser heat transfer urban area. step 3. The newest condenser does not condense really
New compressor compressing proportion increases, the fresh gasoline sign coefficient minimizes, therefore, the compressor refrigeration strength decreases. Increased electricity usage. Should your exhaust temperature is too high, it can help the consumption of compressor lubricating oils, result in the oil thinner and you will apply to lube; when the deplete temperature is close to the compressor oils thumb section, it will bring about the main lubricating oils in order to carbonize and accumulate during the suction and you may launch Valve Slots Impact the securing function out of valve.
step one. Decreasing the heat out-of air conditioning typical decrease new condensation heat and also the condensation stress, but it’s difficult to choose of the maximum out-of the surroundings.
dos. Enhancing the move price out of cooling average can aid in reducing the fresh condensation temperatures a little. However, dont that-sided enhance the cooling water otherwise air circulation, since this increase the air conditioning push or partner and motor strength, is going to be a thorough attention.
The greater deplete stress increase the new compression functions https://hookupfornight.com/craigslist-hookup/ and you may drop-off the fresh new fuel transmission coefficient, which will reduce steadily the air conditioning results.
Now, we will talk about the condensation check out throughout the temperatures exchanger experimentpared toward evaporator test, the latest condenser test is relatively simple. You can find around three managed parameters, as follows:
Indeed, control the brand new condenser inlet stress, you could potentially manage the brand new condensing stress condenser, due to the fact pressure miss condenser is simply really small, approximately since the inlet tension is equal to the newest condensing stress. So how to deal with brand new import stress?
step 1. Manage air amount of the brand new circulate-because of condenser. If for example the sky frequency try high, the fresh condensing pressure will lose
