Listed here are 9 Ideas to know what is the condenser temperatures off liquid chillers

1. Which are the condenser tension and condenser temperature off liquid chiller?

Condensation temperature is the saturation temperatures of refrigerant vapor about condenser within a specific tension. The condensation temperature is not equal to the warmth of your cooling medium, and there’s a difference for the temperature import temperatures between them.

Condensing pressure is the tension where the fresh refrigerant condenses toward a water about condenser. Due to the fact stress for the condenser from the cooling system is not measured, actually, the stress lose of your refrigerant on deplete tube and you can regarding the condenser is very brief. No matter design debugging or fix, basically believed that the fresh new deplete tension is roughly equal to the fresh condensation stress.

2.The connection between condenser temperature and you can condenser pressure

On graph is seen simple, condenser temperature and you can condenser stress try proportional to improve, condenser tension additionally the weather is relevant.

step 3. Estimation away from condenser temperature

During the refrigeration gadgets debugging, we quite often want to know brand new condenser temperatures away free local hookups from liquid fridge and you may determine the newest condenser tension (high pressure otherwise fatigue pressure), so normally legal whether the liquids chiller experience good problem;

In summer, in the event the heavens-trained backyard ecosystem is approximately 35 stages, we can guess the temperature at this time the condensation heat 35 + (10

20 °C)fifty °C, with regards to the heat and you will tension table, it’s easy to find that brand new evaporation pressure at this go out is all about step three.05 MPA (sheer stress, R410A refrigerant) ;

H2o Chillers, the Cooling Tower can guide a fever of twenty-five amount, upcoming how much cash is the condenser temperature of one’s drinking water chiller?

20)40 °C, depending on the temperatures and tension desk, it’s easy to find that this new condensation stress at this day is actually about1.55 MPA (sheer tension, R410 refrigerant)

Using this condenser stress, we can create a comparison into the drinking water fridge system high-tension desk, can be determine whether the water coolant system is normal, ruthless, eventually, is too high otherwise as well lowest, getting repairs debugging or quite beneficial.

cuatro.The connection anywhere between condensing temperatures and Strength of H2o Fridge

About t-s visualize, it is apparent when the fresh new condensing heat of your water chiller experience increased, the power consumed was enhanced;

Associated with very simple, condenser temperatures increased, throughout the evaporation temperature lingering, the newest compressor tension proportion increased, in addition to strength of the compressor was proportional toward pressure ratio, which is, the stress proportion improved, the efficacy of the latest compressor and increased.

Brand new compressor compresses 5 kg from refrigerant in order to fifteen kg from power; indeed far more electricity as compared to compressor compresses 5 kg out of refrigerant in order to 25 kilogram.

5.The connection ranging from condensing heat and refrigerating skill

Regarding t-s image on the cartoon, it is possible to see that the brand new condensing temperature increases, the fresh air conditioning capability of one’s system is shorter.

Right here to spell it out how come, considering the upsurge in condensing temperature, inducing the refrigerants each product air conditioning ability might possibly be smaller, in identical refrigerant mass flow, the machine out-of cooling capability will be shorter.

6.The relationship anywhere between temperatures weight and you can evaporation pressure

The quick answer is the new condensing area of the load and condensing stress relationship. Below a stable performing position (refrigerant flow), the higher the warmth stream, the higher the condensation tension, and you can the other way around. We are able to imagine that after you build the fresh new condenser small (thermal stream is fairly higher), new refrigeration method is very easy to alarm the newest questionable.

There are many reasons toward reduced evaporation temperature. The reason is that there clearly was reduced refrigerant about evaporator or even the throttle device provides an adverse throttling impression

step 1. Expansion Device solutions are highest; dos. Extension Device failure otherwise expansion device starting too big, there’s no throttling feeling; step 3. The refrigerant costs of the coolant system isn’t enough; 4. Brand new refrigeration program does not have refrigerant

(4) The new condenser disrepair, heat transfer skin fouling really serious, may cause large condensation tension. The current presence of scale has a beneficial effect on the latest condensation tension.

step 1. You will find a great deal more refrigerant on the condenser dos. Cooling Solutions possess other periodicals one to take this new condenser heat transfer urban area. 3. The fresh condenser doesn’t condense really

The latest compressor compressing ratio expands, the fresh new gas transmission coefficient minimizes, so the compressor refrigeration capabilities minimizes. Improved energy application. If for example the deplete temperature is way too high, it will help the usage of compressor lubricating petroleum, improve oils slimmer and apply to lubrication; if the deplete weather is nearby the compressor oil flash part, it is going to lead to area of the lubricating petroleum so you can carbonize and gather during the sucking and you will release Valve Harbors Change the sealing function out of device.

step one. Lowering the temperature of cooling typical can lessen the fresh condensation temperature and condensation pressure, but it’s difficult to prefer from the limit out of environmental surroundings.

2. Enhancing the disperse price away from air conditioning average can lessen the brand new condensation temperatures a tiny. However, cannot you to-sided improve the air conditioning h2o otherwise air circulation, because this increase the new air conditioning water pump otherwise lover and system power, will be an extensive attention.

The higher fatigue stress increase the newest compression performs and you will decrease brand new gas signal coefficient, which will reduce steadily the air conditioning results.

Today, we’ll talk about the condensation check out regarding heat exchanger experimentpared towards evaporator check out, the fresh condenser check out is relatively easy. Discover about three regulated parameters, below:

Actually, handle brand new condenser inlet pressure, you can control the fresh new condensing pressure condenser, as the pressure get rid of condenser is simply tiny, just as much as just like the inlet stress is equal to the fresh new condensing pressure. How to handle the newest transfer stress?

step one. Control the air number of the fresh new move-thanks to condenser. In case the sky regularity was high, the latest condensing pressure will naturally drop
