step 1. What are the condenser tension and you will condenser temperature off liquids chiller?
Condensation temperature is the latest saturation temperature regarding refrigerant steam on condenser at a certain tension. This new condensation temperature is maybe not equal to the warmth of the cooling medium, as there are a distinction inside temperatures transfer temperature among them.
Condensing tension is the pressure at which the fresh refrigerant condenses towards a liquids on the condenser. Once the stress inside the condenser on coolant system normally not be counted, in reality, the stress drop of your refrigerant on the fatigue tubing and you may regarding condenser is very quick. It doesn’t matter build debugging otherwise maintenance, generally thought that the fresh new deplete stress is roughly equal to the condensation stress.
2.The connection ranging from condenser temperature and you will condenser pressure
In the chart is seen easy, condenser temperatures and condenser pressure is proportional to switch, condenser tension while the 
weather is relevant.
step 3. Quote of condenser temperature
Inside refrigeration equipment debugging, we quite often need to know the latest condenser temperatures regarding drinking water fridge and calculate the fresh condenser stress (high pressure or exhaust pressure), in order for can judge whether or not the h2o fridge experience an excellent problem;
During the summer, when the air-trained backyard environment is just about thirty five amounts, we are able to guess the heat now the latest condensation temperatures thirty five + (10
20 °C)50 °C, depending on the heat and tension table, you can find that new evaporation stress at that date is approximately step 3.05 MPA (natural stress, R410A refrigerant) ;
Water Chillers, the Air conditioning Tower can guide a temperature from 25 levels, after that just how much ‘s the condenser temperature of the h2o chiller?
20)forty °C, according to the temperatures and you will tension desk, you can easily discover that the latest condensation stress at that date are about1.55 MPA (pure tension, R410 refrigerant)
Using this type of condenser pressure, we are able to make an assessment with the water chiller system highest-tension dining table, can also be see whether the water cooling system is common, high pressure, in the long run, is simply too large otherwise as well lower, to own fix debugging otherwise quite beneficial.
cuatro.The partnership anywhere between condensing heat and Strength regarding H2o Fridge
From the t-s visualize, it is obvious if the fresh condensing temperatures of liquids chiller method is improved, the advantage consumed was enhanced;
Associated with simple, condenser temperature enhanced, in the evaporation heat ongoing, the new compressor pressure proportion increased, additionally the electricity of compressor are proportional towards the tension proportion, which is, pressure ratio improved, the power of the brand new compressor in addition to increased.
New compressor compresses 5 kilogram out of refrigerant so you can 15 kg from power; certainly far more power versus compressor compresses 5 kilogram away from refrigerant to help you twenty-five kg.
5.The connection ranging from condensing heat and refrigerating capacity
About t-s image regarding animation, it is possible to notice that the fresh condensing temperatures increases, the fresh air conditioning skill of your own program is less.
Right here to spell it out why, considering the boost in condensing heat, inducing the refrigerants for every unit cooling capacity could well be quicker, in identical refrigerant mass circulate, the machine out of air conditioning skill is faster.
6.The partnership ranging from temperature weight and evaporation pressure
New quick response is the fresh new condensing region of the stream and you can condensing stress relationship. Significantly less than a steady performing position (refrigerant move), the greater the warmth weight, the better the new condensation tension, and you may vice versa. We are able to suppose once you framework brand new condenser brief (thermal weight is fairly high), the newest refrigeration experience simple to alarm this new high-pressure.
There are many reasons on reduced evaporation temperature. This is because there is shorter refrigerant regarding evaporator and/or throttle valve features a detrimental throttling effect
step 1. Extension Valve choice is large; 2. Extension Valve inability otherwise expansion device starting too-big, there’s absolutely no throttling feeling; 3. The fresh new refrigerant charge of the cooling system isn’t enough; 4. New refrigeration system does not have refrigerant
(4) New condenser disrepair, temperatures import body fouling major, can also trigger highest condensation pressure. The current presence of measure features good influence on new condensation stress.
1. Discover much more refrigerant from the condenser dos. Air conditioning Options enjoys almost every other periodicals that entertain brand new condenser temperature transfer town. step three. The fresh new condenser will not condense well
The new compressor compressing proportion expands, the fresh gasoline signal coefficient decreases, therefore the compressor refrigeration ability reduces. Improved strength application. Should your exhaust climate is too much, it does improve the consumption of compressor lubricating oils, make oils thinner and you may apply to lube; in the event that fatigue climate is near the compressor oils flash part, it is going to bring about the main lubricating oil to carbonize and you will accumulate at the sucking and you may launch Valve Ports Change the closing element out-of valve.
step one. Reducing the temperatures off cooling medium decrease brand new condensation temperatures while the condensation stress, but it’s tough to prefer of the limit regarding the surroundings.
dos. Improving the flow price away from air conditioning medium can reduce the new condensation temperature a small. But usually do not you to definitely-sided improve cooling drinking water otherwise air circulation, as this increases the latest cooling water pump otherwise fan and you may motor stamina, should be a comprehensive thought.
The better fatigue tension increases the newest compression performs and you may disappear the energy transmission coefficient, that will reduce the cooling efficiency.
Today, we shall talk about the condensation test throughout the temperatures exchanger experimentpared for the evaporator check out, the fresh condenser experiment is fairly easy. There are around three controlled parameters, as follows:
Indeed, handle the fresh condenser inlet tension, you can handle new condensing tension condenser, since stress drop condenser is largely tiny, around since the inlet tension is equal to new condensing pressure. Precisely how to handle the newest import pressure?
step one. Manage the atmosphere quantity of this new disperse-as a result of condenser. In case your heavens regularity try highest, brand new condensing tension will naturally miss
