Energy consumption for home air conditioning accounts for almost 5% of all the electricity produced in the USA.Energy Policy Act mandates minimum energy efficiency standards for commercial buildings, using research and standards developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers.Energy Star qualified central air conditioners have a higher seasonal efficiency rating (SEER) than standard models, which makes them about 14% more efficient than standard models.Energy efficiency specialists with certified training on retrofits and energy savings on both residential and light commercial units may enable you to save up to 50 percent on your air conditioning bills with the use of a high efficiency energy system.Substantial energy savings can be obtained from more efficient systems.
SEER (Seasonal Energy Efficiency Ratio) is related to the Energy Efficiency Ratio (EER), which is the ratio of output cooling in Btu/Hr and the input power in watts W at a given operating point and also to the coefficient of performance (COP) commonly used in thermodynamics.SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations.
The SEER rating is the Btu of cooling output during a typical cooling-season divided by the total electric energy input in watt-hours during the same period.SEER is related to the Energy Efficiency Ratio (EER), which is the ratio of output cooling in Btu/Hr and the input power in watts W at a given operating point and also to the coefficient of performance (COP) commonly used in thermodynamics.SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations.The higher the SEER number, the greater the efficiency of your unit. Therefore you will realize greater energy savings.The higher efficiency your product, the lower your long-term energy costs will be.Both central AC and air source heat pumps are rated according to seasonal energy efficiency ratio (SEER).
Before you consider upgrading your cooling equipment, the cheapest way to save money and energy from cooling is to reduce the need for mechanical air conditioning in the first place.Ask your contractor about a variable speed air handler, which will improve comfort and efficiency and allow continuous air filtering at minimum energy cost.Also, because ducts are often responsible for a lot of wasted energy, make sure you hire a contractor who knows about high-efficiency installations.If your central air conditioning unit is more than 12 years old, replacing it with an Energy Star qualified model could cut your cooling costs by 30 percent.
NO!! Never drill holes in any sprinkler system as the size and shape of the holes are very carefully worked out to give you the best cover. Check that your system is running at the designed pressure. This is all important as if it is too much or too little the pattern delivered will be wrong and not efficient. Small holes and high pressures waste water by evapourating too much and cost too much energy to run. Low pressures can result in big droplets which carry well but may over shoot or undershoot the desired path. The most efficient distribution graph of any irrigator is designed to work within relatively narrow parameters.
You really should consult a qualified irrigation technician.
Soap might work. Some use candle wax, bees wax, WD 40. I've prayed silicone on the drill bit. Using moderate pressure and low speed definitely helps, and it is essential to clear out the hole of chips frequently. So drilling in increments works. You drill a little, lift the bit up out of the hole to clear the chips. Also the type of bit used is a factor in drilling efficiency: wood boring bits are a good choice. Forstner bits are excellent, and spade bits are just OK. Hope this helps....
These are designed to retain some water in the pan. This is for the slinger fan to throw water through the condensing coil. This helps the refrigerant cool and is important to the efficiency of the unit. I would certainly not recommend drilling a hole in the bottom. The hole may cause the water to roll somewhere where damage could occur. Try instead tipping the unit Backwards before bringing it in the house.
Please follow the below steps to use a electric drill -
1. Determine which electric drill is best for you, the cord or cordless. The electric drill that has a cord attached needs to have an outlet which might limit you according to what job you are doing. The cordless drill is limitless and can be used anywhere without needing an outlet. Corded drills can be more powerful, where cordless drills are limited to power and can sometimes be a bit bulky.
2. Consider most of the jobs you may use an electric drill for. If you have a lot of heavy-duty projects ahead, you might want to purchase a more powerful drill. They run slower but have the power behind them to get the job done efficiently. The more powerful drills usually have a cord attached to them. If you have a lot of lightweight jobs to use a drill for, then a cordless one may be your best selection.
3. Arrange the work to be drilled either straight ahead of you or down below you. These are the two safest ways to use a drill. The drill is also more secure and won't waver while using it. If the material you are drilling is a hard or thick material, use a hole punch to start the hole before you drill.
4. Push the drill slightly as you are drilling to give a bit of added force. Start out slowly, and as the hole progresses, increase the speed slightly.
Tip - Secure your work before drilling by using clamps. The more powerful the drill, the slower it drills. The less powerful the drill, the faster it drills.
Warning - If you are using a cordless drill, charge the power pack before starting a job. Keep the air vents on the drill clean, and clear of any debris so the drill does not overheat.
It probably shut off on high pressure. Let it cool down, plug your hole that you drilled and give it another try. The water is suppose to collect there and the fan is suppose to throw it into the condenser to keep it cooler and make it run more efficiently. Good Luck,
Modern window units intentionally do not allow the water to drain directly, they want the fan blade to sling the water on to the condensor (the coil that is outside) to aid in cooling actually helps the unit cool better in high outside temps, it also evaporates it this way, depending on where the hole was drilled it may be able to be repaired, if it was just a copper tube it will be less expensive than replacing the whole coil. Since its a relative inexpensive unit anyway the labor and freon may be more than its worth. Lesson learned dont drill a hole in the base it lowers it's efficiency and can lead to a punctured freon line.
