Air conditioning can between effect grade and real power consumption, without too big concern. This are the misdirect of the person that businessman offset is expended actually, not be to say air conditioning can effect order and degree is higher (the number is smaller) , power consumption is smaller. The businessman offerred a very ambiguous term -- " province report " , province report, the product that is need and coequal class undertakes contrast. Cite a case, motor-car of a report, can run continuously 5 kilometers, this basically calculates comparative not to omit report; A mobile phone, can play game continuously 45 hours, this is special province report.
The mobile phone that we take this province report now and the electric motor-car that do not omit report are put together, ratio when biding one's time, grow, electric car is over absolutely get the better of -- can not compare a gender at all, also do not have any meanings as a result quite.
Air conditioning also is same, 26 model air conditioning mixes 70 model air conditioning compares power consumption, no matter this 70 model what air conditioning does is much better, also no matter this 26 model what air conditioning does is much soddener, 70 model the power consumption of air conditioning is met necessarily prep above 26 model air conditioning -- because their itself was not put in same aspirant travel compares a platform.
Air conditioning can effect gradeAir conditioning can effect grade, call air conditioning again can effect comparing, just as its name implies, it is efficiency and bad news can ratio ▼
See an unit also can see " H of · of W · H/W " . What is the efficiency of air conditioning? It is time of refrigerating capacity * -- the cold tolerance that produces inside unit time; The bad news of air conditioning can, be opposite namely of electric energy use up, it is time of refrigeration power * -- how many what use up to electric energy inside unit time. (air conditioning can effect comparing makes Leng Jin classification all right to air conditioning only, take no account of when making heat can effect comparing. )
Bad news reportAccordingly, can time of * of refrigerating capacity of effect comparing = / refrigerating capacity of = of time of refrigeration power * / refrigeration power. Noticed, there can be two variables in effect comparing -- refrigerating capacity and refrigeration power, refrigerating capacity rises or refrigeration power is reduced, can increase can the ratio that effect compares. So, below the premise that takes no account of refrigerating capacity and refrigeration power, pure through comparing can effect comparing, say whether an air conditioning expends report, be absolutely mistake!
If want to compare some two air conditioning which more province report, the refrigeration power of their both and refrigerating capacity, having at least among them is identical, ability is passed quite can effect goes out than judge which more province report. But the power consumption that wants to know an air conditioning, do not need so troublesome, need consideration only its refrigeration power went.
Refrigeration power, namely a few when we say at ordinary times, for instance 1, 1.5 wait. 735W of a ≈ (actually, a =735W, it is nevertheless in the expression of air conditioning, the air conditioning that controls 735W calls 1) .
With refrigeration power (KW) * time (hour) , it is the power consumption of this air conditioning inside unit time (KW · H) .
Real power consumption is calculatedWe see a problem advocate the ▼ of this piece of graph that offers to us
Of this air conditioning can effect comparing is 3.51, refrigerating capacity is 2600, what mention according to above paragraphs is formulary, can calculate piece, 741W of ≈ of refrigeration power =2600/3.51, namely an air conditioning in fokelore. This air conditioning lasts full power works 1 hour, power consumption is 0.74*1=0.74KW · H, namely 0.74 degrees of report.
Attention, there is a keyword here -- " continuously full power works " . Is air conditioning to last full power works? Not be of course! To calm frequency air conditioning, after temperature reachs user set temperature, air conditioning can stop indoors machine; To frequency conversion air conditioning, after temperature reachs user set temperature, air conditioning can reduce rotate speed indoors.
Machine down time (or run time of low rotate speed) concern with the heat preservation effect of the room -- heat preservation effect and room size, whether positive aspect window, sealing waits about; Continuously full power run time, concern with temperature of refrigerating capacity of room size, air conditioning and user set -- the specific value between room size and air conditioning refrigerating capacity is less, set temperature is close to room temperature more, continuously full power run time is shorter.
In addition, the starting electric current that considers air conditioning even -- when air conditioning compressor is being started, can produce bigger electricity, expend higher electric energy.
Anyhow, problem advocate those who ask about: One in the evening specific power consumption a few degrees of report? I do not have the answer with accurate method, this must want to know your set temperature and room size.
