Really ? The only brushless DC motor I am aware of is the ECM motor.
Electrical commutated motors and again, uses an inverter to send a manufactured sinusoidal waveform to basically do the work of the commutator.
And to what solar rig are you referring to ? A electronics parts outlet in my city runs a solar rig that incorporates at least 6 batteries ?

All of these are excellent questions that will go largely ignored by the true believers of the AGW religion. And the usual retort is to come after your character as some sort of dolt, denier, or worse. So in their world, personal attack is fine when they can't reasonably answer the hard questions.
Americans are so enamored of equality that they would rather be equal in slavery than unequal in freedom.

Those ductless systems just started to get popular in the US in the last few years.
At first I had my doubts but they're pretty dependable and highly effecient.
The small line going from the condenser to the air handler unit is actually the metering device distributor line. ( saturated refrigerant leaving the metering device and entering the evaporater coil )
In a conventional unit its usually carries medium temp liquid to the TXV metering device and distributor in the indoor unit.
The TEV ot TXV is in the outdoor unit, not the indoor unit. Both the lines have to be insulated to stop condensation problems.
You can measure the temp of each line with a K or J type thermocouple and get a "super heat" reading when your unit is cooling.
You can determine the correct charge under normal load conditions. should be around 12 to 16 degrees.
I like the high efficiency the inverter units are hitting.
If people want to really reduce high energy use in the US, home comfort is the low hanging fruit.
Better insulation, radiant barrier, windows, all reduce the heat load, the next piece is the
You first maximize the R value of your envelope then size your capacity accordingly.
Ive seen people who went to great expense turning their home into a igloo cooler only to run into humidity problems and the dreaded sick home syndrome.
They increased their r value to the point their AC was now oversized so it would pull down the temperature but not the humidity because it wouldn't run long ennough. Thats a very costly scenario to back out of.
People dont realize that a AC isn't about lowering temperature but about lowering total enthalpy which includes humidity. Down in Houston much of the capacity is used for humidity removal.
My sister in law has a beutiful high effeciency home (4k sq ft ) with two stage AC units ( two ) cooling it.
At 76 degrees its verry comfortable in her home and the two stage unit once temp is satisfied will lower its blower speed and compressor cappacity to lower the humidity.
New tech is amazing.
Nobody is trying to predict future weather. They're trying to predict future climate. They aren't trying to predict individual weather events, but rather a statistical average that can be expected in the future. It's a pretty important difference.A few other, well, elementary school level questions. When we can't predict tomorrow's weather, how, when the earth is billions of years old and we have 150 years of recorded data, are we able to predict future weather?
Wrong. All of those terms have been around for decades, and are often used interchangeably.So many people claim global warm.....er.....wait now it's climate chang......er....no now it's anthropogenic global climate change,
Also wrong. There are climate deniers, and there are skeptics. The deniers are the ones who, deliberately or not, present ridiculous arguments, straw men, or outright lies. There are skeptics in the scientific community who do excellent and important work. You should familiarize yourself with those people.is "scientific" and if you don't buy the (Uncle Joe's fav word) mularkey they offer you are a "science denier", yet those same people accept "consensus". How is this rationalized?? Please explain to me, using "scientific" principles (btw for the low information voters here, "consensus" is antithetical to "science"), how having the conclusion prior to even forming a hypothesis, let alone using ALL data available and not just seven trees that support your pre drawn conclusion, how you expect to be credible.
A change in northern hemisphere insolation due to regular, cyclical changes in the earth's axial tilt. This isn't difficult information to come by. If you lack even this basic knowledge of climate history, you should refrain from posing these "questions" with the assumption that nobody can answer them.What caused the end of the last ice age?
On average, global volcanic activity generates about 200 million tons of CO2 per year, according to the US Geological Survey.How much CO2 was emitted during the eruption of Mount Vesuvius?
One of you will end up here next!
