In Representing the Power of a Compressor, What Is the Difference Between Compressor's Hp and Driver

The driver represents horsepower available. The compressor represents the horsepower required. Typically the available is greater than the required by some amount.

1. minimum-working example for schematic diagram of a compressor

A compressor has a motor and the motor is attached to a load that has torque that has to be overcome to get it to rotate because of the piston compressing on each rotation. From this site: Once the motor starts rotating at a reasonable speed, the inertia of the parts helps overcome the torque as the piston compresses the refrigerant, but as it is getting up to speed there is a large current draw. That causes a voltage drop in the wiring and would possibly cause the circuit breaker to open if it continued (say if the compressor was stalled). Lights may be more sensitive to voltage than you would expect from the voltage drop, for example a 10% drop in voltage may cause a very visible drop in light intensity. As far as a model goes, you could model the system mechanically with SPICE. The motor current draw is strongly dependent on the RPM (because of back-EMF) so it draws maximum current when stalled. The motor torque is approximately proportional to the current draw. And the compressor could be modeled with the above torque angle curve. So as the motor-compressor combination winds up from start there would be large pulses of current that quickly increase in frequency and simultaneously get smaller as the motor gets to speed. Note: I do not think domestic fridges have an unloader, but larger A/C units and larger air compressors typically have a valve that relieves the compression until the motor and compressor parts get moving. Maybe someone can correct me if that is wrong. Here is an interesting video of the internals of a fridge compressor. Usually the light dimming issue is not noticeable because the fridge is on a different circuit than the lights. The DIY SE would have more to say about those considerations

2. Trying to pick out an air compressor for my husband?

Lowes, Home Depot and Sears all sell good air compressors and have units at reasonable prices. Talk to the sales people and see what any particular one will handle in the way of tools or paint guns. The real small ones (Pancake style) are only for nail guns and such and wo not support spray guns or impact wrenches. Most of the medium size compressors should work for what your husband wants. Look at the price range you feel comfortable with and ask them what it will support in the way of tools with only occasional use

3. Noise from A/C compressor on 01 Impala?

If you are certain that it is a bad compressor, then yes, you could replace it. It requires that the freon be recovered prior to dis assembly, once you have removed the old compressor, you will need to service the replacement compressor with the correct amount and type of oil. This will be in the paperwork that comes with the replacement compressor. Once assembly is complete, you will need a vacuum pump to evacuate the air and moisture from the system, normally takes about 30 minutes with a good pump. Most techs recommend replacing the orifice tube and receiver dryer when a compressor is replaced, I agree with that practice, but that is up to you. When vacuum process is complete, close system and let sit for 30 minutes, during this time observe the vacuum gauge to make sure that you do not loose vacuum. If vacuum diminishes, this means that you have a leak that must be found prior to servicing with freon. If vacuum remains steady, service through the low side of the system with the correct amount of 134A with the system operating on high. Good Luck

4. What Causes Air Conditioning to Stop Working?

If your air conditioning unit has stopped working, there are many possible reasons that can explain why. It could be your thermostat, your air filter, a problem with the condenser or compressor, or it may just be time to replace the unit, especially if it's over 10 years old. Whether you need a replacement or a repair, Ambient Edge is the company to call. Reach us at (888) 240-8283, and we will do everything possible to get your air conditioner working again. If we can not fix it, then we will work with you on picking out a replacement unit that's right for your home and your budget. Reasons Why an Air Conditioner May Stop Working If you've noticed your air conditioner is not running the same way it used to, or if it simply is not as energy-efficient as it once was, it's important to get to the bottom of the problem. You want to figure out sooner rather than later what the issue is, especially if your AC is decently new, before a smaller issue escalates into what can become an unfixable problem. Here are some of the more common issues to affect air conditioners, as well as some suggestions on how to fix them. Nothing can cause more dread with an air conditioner than turning it on during a heatwave, only for it to blow hot air in your face. Yuck. There are a few reasons why this might happen. Some of the simpler causes may be that a vent is closed, or that the thermostat needs fixing. Some more major causes may be that the unit is low on refrigerant, signaling a leak, or that there is a problem with the fan. Either way, if your unit is blowing out warm air instead of cold, give a professional a call to come and take a look. If your air conditioner wo not turn on at all, this could be because you have a dirty air filter, or there is a minor issue with your thermostat. You may also want to check the circuit breaker to ensure it did not trip. Check the AC shutoff switch to ensure it is not engaged and check the AC drain pan beneath the unit. If the pan is full or the drains or clogged, this may be enough to trigger the machine into safe mode, and it wo not turn on. Failing these troubleshooting tips, if the machine still refuses to turn on, call an HVAC professional. Your compressor may have failed if: The system shakes when it starts. The system makes strange noises when it runs. Do not panic if you think your issue may be your compressor. This is not always a major problem and, as such, it does not always cost an arm and a leg to fix. You will know your compressor issue is more serious if the unit frosts over or, conversely, overheats, or if it is cycling more frequently (turning off and on). However, your issue may be related to something less severe, like an electrical issue, a problem with the refrigerant or oil levels, or pollutants in the system. If you are experiencing any of the above issues with your AC, call our technicians at Ambient Edge for help. The Unit Continuously Cycles On and Off The way an air conditioner works when you allow it to cycle is that it turns on when it senses an increase in the temperature so as to regulate the climate of the room. When it cycles too frequently, however, you know there's a problem with the unit. There may be several explanations for why the unit is cycling too often. It may have a compressor issue, a fan issue, or an electrical issue. You should handle none of these things if you have no experience repairing air conditioners in the past. Let Ambient Edge help by inspecting, diagnosing, and repairing the issue for you. Is Your Air Conditioning Not Functioning as Well as It Should? Let Ambient Edge Take a Look! At Ambient Edge, we run the gamut insofar as what we offer when it comes to repairing air conditioners. We can repair the issue you are currently experiencing, recommend a new system if your system is old or too far gone to fix, or set you up with a preventative maintenance contract.

Is It a Good Idea to Cover Up Your Outdoor Air Conditioning Unit (compressor) with a Plastic Tarp fo
sure I would think it would protect the components in side1. My central air conditioning unit isn't working. How can I get it to work?You need to give much more detail to get a helpful answear to this question. Try to describe just what is going on and what you have or have not tried2. what is the cause of bad smell on home air conditioning unit like split type?The unit probably needs cleaned. The condensate drain pan can get some stuff growin in it and the coil probably needs cleaned. The whole system requires some routine maintenance. For more info, check out the ductless ac page at www. hvac-for-beginners. com.3. What type of regular maintenance should I be doing on my central air conditioning unit?Check/Clean/ Change filters or Electronic air cleaner, inspect blower motor wheel for cleanliness and alignment, check capacitors capacitance, check evap coil cleanliness and ability to transfer heat(delta tees), check filter driers inlet outlet temps, anything above 3 degrees is a restriction/moisture, condenser coil cleanliness and ability to transfer heat. 10 degree delta tees are acceptable. Generally not performing annual maintenance will also void manufacturers warranties or labor warranties. Two schools of thought on checking refrigerant levels are it should be checked annually to see if there is a leak that's formed or you should not because every time you gauge up you are removing charge from system. With new low loss hoses and ball valve hoses refrigerant loss is kept to a minimum so it's less of a concern. Then again if you just put a system in a year ago and you are just doing basic check-up, getting involved is not necessary. A good tech will be able to know when he/she should be gauging up based on the temperature readings they get while checking the indoor unit, after letting the system run for 15 min, which is usually done while performing the AHU maintenance4. Outside residentual air conditioning unit has huge block of ice.... in 80 degree weather.?Yes, turn the unit off until it has completely thawed out to prevent permanent damage. The coil inside the furnace unit is likely "frozen up" as well and could take several hours to completely thaw. Once thawed... the system may work until it starts to freeze up again, but likely wo not cool like it should until properly charged. Minimize use and closely monitor until repairman can take a look. Could be other things, but does sound like low freon in the system. A quick check with gages by a A/C pro will determine.5. I WAS TOLD I NEED TO REPLACE MY COMPRESSOR UNIT ON MY WHOLE HOUSE AIR CONDITIONING UNIT BY YEARS END?Hi, yes there is a phase out of R22 by the end of this year, but initially stop producing of virgin refrigerant, but you can still use recycled R22 up to 2015, but the european government are looking to bring this date forward. but this might not concern you as your unit might not be using R22, you need to find out what refrigerant your system is operating on and post it, all system now can be retrofitted using new more friendly refrigerants but all HCFC refrigerants are to be phased out within the next ten years but by this time arrives your A/C unit will be past it life expectancy. Your unit can probably be retrofitted to a different refrigerant and oil compatibility is no longer an issue as the old mith you cannot mix them is long gone as they now tell you to mix them in some retrofits. Just be careful as engineers will try and replace your unit because they will get a new install out of it and perhaps do not have the experience with the retrofitting process. Regards6. What is better, an r22 Air conditioning unit or a r410?when did the r410 come out about what year ??7. where can i find info. on my air conditioning unit?i dont know but thanks for hte two points just playing go to google duh8. If I am replacing my central heat and air conditioning unit, is it cheaper to stay with the same brand...?Unless you have a special situation, it wo not make a difference. They all hook up the same way. Check the efficiency rating vs cost. If your central unit is right outside a bedroom window, or above a living area, you want to find a quiet one.
