Well and it's me that I'm offending? You're igno
Engieneer or not you might go better at studying! You did not even understand what I wrote!
CIT
"Gas drying is not more efficient than heat pump plus it's a fossil fuel, heat pump can be run with electricity that could be generated from clean resources like nuclear or renewables. Total efficiency is better because gas adds humidity to the cycle and per each unit energy burned will dry for 2/3 of it as the hot air is already moist form the combustion. Heat pump will dry the air during the cycle and use only one unit of energy per 3-4 units of drying. (others degreed guys please forgive me for using "units" and not actual values but I want to be clear for everybody!)"
Oh do you really think being so smart? Might be best for you if instead speaking and thinking like a very doubtful engineer making unuseful calculus took from the air or looking from where the energy come from renewable or not would think about costs of energy, drying times and also performances, I look rather for the cost of every energy source and bill to pay not from where it come and so I care also of efficiency on the performances! I care to have a dryer that works and gives me a dry load in less time! I don't care if it use renewable sources or not! You state that an heat pump can eleminate all the moist to the air before being put in recirculation making it totally dry....where? So please let me know what you think about heat pump being longer compared to others conderser but electric!
CIT "You could check data sheets (ops, in the USA they don't list energy consumption of dryers!) and discover that a gas dryer uses 30% energy more than an equivalent electric one. A heat pump will use 1/4 of that, factoring in the production efficiency for electricity at an average of 40% the heat pump will use LESS primary energy than a gas dryer."
How can you compare electric energy to gas energy? It will even use "more energy" but if that energy is the one that cost way less even if it phantomatically would be 30% more and would let me save is the thing I primarily care like most americans!
And I just know that running even a 1000 watts for an heat pump is way more expensive than run a gas dryer......even because the gas one would get the job done quickly.
So we just have to state what energy efficience is at this point!
CIT "Weight the average European 6 kg load and tell me if it's bigger or smaller than the average American "large volume" load and get back to me. We had this discussion in the forum millions of times already. You can have a drum of 6 cubic feet, 10 or whatever you want. As long as the power heating and airflow are sufficient you can have fast drying times."
Yes I can totally say that the 6kg load rated for EU is just absolutelly smaller than the American Large volume! TOTALLY!
And you would say that a more packed load would dry as if it was freely to swish in a bigger drum? Okay Mr Engineer! That's just enough!
CIT Commercial heat pump dryer in our laundy dryes stuff in the same time of the old vented one at around 25 minutes for a full 20 kg load while using 1/3 of the energy of the old one. Go figure if isn't as fast. The compressor is rated at some 5 kW of power.
Where??? Never seen a 20kg dried in 25 minutes in a laundromat with heat pump! Never!!! ratehr 40 mins for 8kg load! let's don't talk about 20kg!!! I hope you're kidding!
CIT This is almost offending: you are the IGNORANT, I was exactly speaking of efficiency. If you make the hot side of the heat pump "hotter" and the cold side "colder" you will lower the efficiency of the cycle but will have a faster drying time because of the improved moisture removal of the higher temperature (more humidity can be taken from the hot air) and improved condensation.
Such a system will be more efficient than a simple vented or classic condenser dryer compared to the current offering. Consider that since American dryers are exempt from Energy classification they are generally less efficient than European dryers be them vented or condenser and terribly inefficient compared to heat pump ones.
You can't make an heat pump hotter! Is right what you say about hot and cold and condensers but you cannot elimiate all the moist from the air before being put in recirculation so you can't say it would be more efficient than a vented one gas or electric it will be, (also I can tell you most americans finds gas ones being even faster) this is impossible! And you would be an engineer??? Well if you studied in Italy it probably is......I offended you now? Well I just don't care, I just said the truth as in Italy everyone can BUY a degree!
Then the fact that american dryers are exempt from energy classification (not true as anyway the consumption are rated in the "Energyguide") let you say that they're less energy efficient??? AND WHY????
CIT Yes, you're utterly ignorant and stupid. You should wash you mouth with soap and vinegar before attempting to answer me back.
It's not numbers I'm inventing, you could try yourself putting a power meter on a classic electric dryer (choose your style, American and European) and a heat pump one, you'd be amazed at how different will be the electric consumption of them!
Well I will not say that you're stupid but arrogant you're for sure.
I'm curious to know if youn did this experiment of the power-o.meter indeed!
No invented numbers.... well they actually looks so for my advice...and I never said they don't allow you to save money, they could let you save just a little bit, I only said that for the few money they could let you save I think for many americans they would not be worth it as they would be obviously longer and less efficient on performances![this post was last edited: 8/5/2012-15:08]
