step one. Exactly what are the condenser stress and you may condenser heat out-of h2o fridge?
Condensation temperature is the latest saturation temperature out-of refrigerant steam on condenser in the a certain pressure. The newest condensation climate is maybe not comparable to the heat of your own cooling typical, and there’s a distinction into the temperatures import heat between the two.
Condensing stress ‘s the stress where the brand new refrigerant condenses towards the a water on the condenser. Since pressure from inside the condenser about cooling system normally never be counted, in reality, the stress miss of refrigerant regarding exhaust tube and you may in the condenser is very brief. It doesn’t matter construction debugging otherwise repairs, fundamentally thought that the newest deplete pressure is approximately comparable to the condensation pressure.
dos.The partnership anywhere between condenser temperature and you can condenser pressure
Throughout the chart is seen quite simple, condenser heat and you may condenser pressure is proportional to alter, condenser tension plus the climate is related.
3. Quote out-of condenser heat
From inside the refrigeration equipment debugging, we quite often need to know brand new condenser temperatures out-of liquid chiller and you can determine new condenser pressure (high pressure or deplete stress), so can courtroom whether or not the liquids chiller method is a problem;
During the summer, in the event the heavens-trained outside environment is around thirty five level, we are able to guess the warmth now the condensation temperature thirty-five + (10
20 °C)50 °C, with regards to the temperature and you can stress table, you can realize that the evaporation stress at this day is all about 3.05 MPA (absolute pressure, R410A refrigerant) ;
Liquids Chillers, brand new Cooling Tower could book a temperature from 25 grade, after that simply how much is the condenser temperatures of drinking water fridge?
20)forty °C, according to the temperature and stress table, you can easily find that the new condensation tension at this go out is actually about1.55 MPA (sheer stress, R410 refrigerant)
Using this condenser stress, we could generate an assessment for the h2o fridge program higher-pressure dining table, can also be see whether the water coolant system is normal, high-pressure, finally, is actually large otherwise as well lower, to own maintenance debugging otherwise quite beneficial.
cuatro.The partnership between condensing temperature and you may Electricity out of Drinking water Fridge
From the t-s photo, it is obvious that if the fresh condensing temperatures of your own drinking water chiller method is enhanced, the benefit consumed try enhanced;
The reason is very simple, condenser heat enhanced, regarding the evaporation temperature ongoing, the newest compressor pressure proportion enhanced, therefore the strength of compressor is proportional with the pressure ratio, that is, the pressure proportion increased, the effectiveness of the fresh compressor and enhanced.
Brand new compressor compresses 5 kilogram away from refrigerant in order to fifteen kilogram out of power; yes way more electricity compared to compressor compresses 5 kg away from refrigerant to 25 kilogram.
5.The connection between condensing temperatures and refrigerating ability
Regarding t-s photo about cartoon, you can observe that the fresh new condensing temperature increases, this new air conditioning skill of your own system would-be less.
Here to spell it out the reason, considering the rise in condensing temperatures, inducing the refrigerants for each and every product air conditioning capability could well be reduced, in identical refrigerant size flow, the machine of cooling skill was faster.
six.The partnership between heat stream and you may evaporation pressure
The fresh quick answer is the fresh new condensing area of the weight and condensing stress dating. Around a steady doing work reputation (refrigerant flow), the greater the warmth stream, the higher new condensation pressure, and you may vice versa. We can suppose that when you framework the newest condenser short (thermal load is fairly higher), the fresh refrigeration system is an easy task to security the newest high pressure.
There are many reasons to the lower evaporation temperature. The reason is that there’s faster refrigerant in the evaporator or the throttle device keeps an adverse throttling effect
1. Extension Valve options is higher; dos. Extension Device incapacity or expansion valve opening too big, there’s absolutely no throttling impression; 3. The fresh refrigerant fees of cooling system is not adequate; 4. The brand new refrigeration program lacks refrigerant
(4) This new condenser disrepair, temperature transfer body fouling big, also can result in higher condensation tension. The presence of size features a beneficial affect the fresh new condensation tension.
step 1. You will find more refrigerant throughout the condenser dos. Cooling Solutions has actually other periodicals one to undertake the brand new condenser heat import urban area. step 3. New condenser will not condense better
Brand new compressor compression proportion increases, the newest gasoline indication coefficient reduces, so that the compressor refrigeration ability decreases. Improved fuel consumption. Should your exhaust climate is too high, it can increase the consumption of compressor lubricating oils, make the oil thinner and you will affect lube; when the fatigue weather is near the compressor oil flash area, it will likewise end in an element of the lubricating petroleum in order to carbonize and you may accumulate at suction and you may discharge Device Slots Impact https://hookupdaddy.net/milf-hookup/ the sealing ability from device.
step 1. Lowering the temperature off air conditioning typical decrease the latest condensation temperature while the condensation stress, but it is difficult to favor by the limitation out of environmental surroundings.
dos. Enhancing the move price away from cooling medium can aid in reducing this new condensation temperatures a little. However, usually do not that-sided boost the cooling water otherwise air circulation, because increase the newest air conditioning pump motor or fan and you can engine strength, are an intensive said.
The greater fatigue stress increase the fresh new compression really works and you may drop-off the fresh gasoline sign coefficient, that’ll decrease the cooling abilities.
Now, we’re going to talk about the condensation experiment about temperatures exchanger experimentpared into the evaporator check out, new condenser test is relatively easy. There are around three managed details, below:
In fact, control the fresh condenser inlet tension, you could handle the latest condensing stress condenser, since pressure shed condenser is simply really small, up to because the inlet tension is equal to the new condensing pressure. So just how to deal with the fresh new transfer stress?
1. Manage the air quantity of the disperse-because of condenser. In case the air frequency are large, the condensing stress will naturally drop
