Basic Science Confirms Cold Air Intake Systems Increase Horsepower And Torque

By O Wolff

The fire triangle is simple enough, begin with a supply of fuel, then add an igniter and oxygen, and voila, you have fire. Now when was the last time you gave that any thought while driving your car? Most of us aren’t harkening back to Science 101, and why should we? The answer is because by making one straightforward change in the way your car gets oxygen, you can increase the heat of the engine fire. By intensifying combustion, you will be rewarded with improved engine performance.

When it comes to enhanced performance, science has proven that cold is good. Elite endurance athletes use a technique called ‘pre-cooling’ whereby they lower their body temperatures by icing or other means before a competition. A cooler core temp then allows them to maximize greater oxygen uptake for longer periods. When it comes to your vehicle that technique roughly translates into adding a cold air intake.

With a cold air intake the air filter is relocated away from the engine-heat, thereby allowing cooler air to feed into the engine. Cooler air is denser and carries more oxygen per cubic-foot, which generates a more intense and efficient explosion in the combustion chamber. A bigger boom translates to more power and torque.

But that’s just part of the fire triangle power equation. By tuning the air inlet pipe’s length and diameter to match the engine’s resonance, even more cool air can get fed into the cylinders, producing further power gains. Additionally, a cold air intake reduces air restriction so your engine doesn’t have to work as hard to pull in air. This also contributes to air being more dense and rich with oxygen. Thus, by replacing your vehicle’s stock air box with a cold air induction system, you do away with one of the biggest restrictions to your engine’s overall performance and wellbeing.

So the question that begs to be asked then, is if a cold air induction system does all these extraordinary things for your vehicle, why don’t they come as standard equipment from the factory? The answer to this question is that automakers design their vehicles to accommodate the greatest number of drivers and styles possible, or the lowest common denominator, depending on your view. That sort of logic produces vehicles tuned for the ‘average’ driver. They also have other design issues to consider like sound. Many drivers love the roar you get with a cold air intake when you hit the pedal hard but some like the quieter ride an OEM intake gives them even when they are flooring it. If you want your engine to live up to all that it can be go with a cold air intake, that’s a decision you will have to make.

Hovering at the top of anyone’s list of go-to cold air induction systems should be AEM. They began pioneering cold air intake systems for sport compacts cars back in 1994, and today their list of applications continues to grow to include most makes and models. This is a company that prides itself on first working out the science in their factory, then testing in the lab and on the road. If you’re looking to upgrade from ‘lowest common denominator’ to ‘why didn’t I do this before’ make sure you pick a reputable manufacturer in any case. Pick one that offers a lifetime limited warranty on all their cold air intake systems including the air filter. What are you waiting for? Perhaps it’s time to put some of those early science lessons into practice by stoking the fire in your engine and dialing up the performance heat.

Sichuan Changhong Electric (600839, closing price of 4.85 yuan) today issued a public notice that the board examined and approved the transfer of company ownership means the listing to sell holdings of Sichuan Changhong Air Conditioning Co., Ltd. (hereinafter referred to as Changhong air conditioning) 100% equity and Zhongshan Changhong Electric Co., Ltd. ( hereinafter referred to as Zhongshan Changhong) 90% stake. The transfer of issues need not be submitted to shareholders for its consideration. Company will receive the state-owned asset-management division after the approval and filing procedures for fulfilling a specific listing.

To avoid intra-industry competition

In its announcement, the company said, according to company’s strategic development needs, in order to avoid holding subsidiaries and Meiling Electrical (000521, closing 6.81 million) in the white power industry there is the potential to compete with the industry to fulfill the acquisition Meiling appliances, the commitments made by agree that the state-owned asset management company under the relevant provisions of the transfer means to transfer the listing of property rights held by the 100% stake in Sichuan Changhong air conditioner (including the company held 99% directly owned subsidiary of Sichuan Changhong equity and Innovation Investment Co., Ltd. holds 1% stake in ), and Zhongshan Changhong 90% stake.

Announcements, Changhong air conditioner is mainly engaged in domestic air-conditioning business, research and development, production and sales. As of June 30, 2009, Changhong air-conditioned with total assets of 5.91 billion, total liabilities of 289 million, equity 3.02 billion in the first half of 2009, Changhong air-conditioning to achieve operating income of 699 million yuan, operating profit of 5.9965 million yuan, net profit of 3.6031 million yuan. To June 30, 2009 as the base, Changhong air conditioner 302 million book value of equity to assess the value of 290 million yuan to assess the value of -1108.15 million, value-added rate of -3.67%.

Zhongshan Changhong air conditioner is mainly engaged in the business of overseas R & D, production and sales. As of June 30, 2009, Zhongshan Changhong’s total assets of 3.32 billion, total liabilities of 245 million, equity of 86.834 million yuan, Zhongshan Changhong first half of 2009 to achieve revenues of 146 million, operating profit of 3.2537 million yuan, net profit of 2.5233 million yuan. To June 30, 2009 as the base date, Zhongshan Changhong equity book value of 86.834 million yuan to assess the value of 114 million to assess the value of 27.1486 million yuan, value-added rate of 31.26%.

Sharp drop in air-conditioning business

In fact, Guotai Junan analyst Wang Zhen in the analysis when semi-annual report, Sichuan Changhong said: “Sichuan Changhong’s air-conditioning business is likely to be a loss.” Analysts believe that perhaps the rush to sell its air-conditioning, Sichuan Changhong, one of the reasons the company.

Sichuan Changhong semi-annual report published in 2009 showed that the first half operating income of 13.277 billion yuan, net profit of 030 million yuan, down 22.56% year on year, of which the contribution Meiling Electrical 6.57 million yuan, China intended to contribute 13.75 million yuan compression, the National Rainbow Communications contributed 32.17 million yuan, while the parent company has a loss of 46.8 million yuan. This shows that mobile phones, white and the upper reaches of compressor is the main source of profits, but the urgent need to improve the profitability of TV business.

Wang Zhen pointed out that Sichuan Changhong semi-annual report point of view, white drop is relatively small, mainly due to Meiling refrigerator. White income was 2.957 billion yuan, down 10.37 percent year on year; of these Meiling refrigerator income of 2.43 billion yuan, an increase of 9.1%, gross margin reached 29.4%. According to estimates, air-conditioning revenue declined more than 50%, gross margin fell ultra-80%, gross margin was only 11.8%. Therefore, Wang Zhen that the air-conditioning business is most likely a loss.

Although the above proposed transfer of two listed companies have a profit, but profitability is not good. Thus, some analysts believe that Sichuan Changhong to Meiling Electrical more profitable, but has abandoned its traditional air-conditioning company.

How To Select An Air Conditioning System

Submitted by: Adam Zebrewski

How do you decide what to choose when you need a new air conditioning system? What are the best brands? Which have the lowest operating costs. It is actually more important to have the right buying process, instead of worrying so much about the getting the right brand.

Surprisingly, the government model is actually the best way to buy a system. You want to set up a bidding process where you get 4-6 heating and air conditioning companies to quote on the job. The Better Business Bureau is a great place to look for suitable companies. They should have at least 10 years experience.

Any half-way decent company will give you a free estimate. Let them know they will be bidding against other companies. Make sure you do not tell them what the other companies bid amounts are. You can explain that you are going to award the job to the highest value bidder – which means the most for the least. If they are intent on selling you a particular system, have them explain why it is the best.

The truth is that the well known name systems out there are somewhat comparable in quality. No system will run forever, though. Plan on future maintenance by getting a system that has standardized parts. If it has specialized parts, it is going to be more difficult and more costly to repair. Also, your future repairman may have limited experience with specialized parts. You want him working with the same thing he is used to every day.

Trane and Rheem are thought to be top of the line. Well designed, Rheem units are reliable and simple for most technicians. You can expect top quality workmanship. Trane, too, is a wonderful system. Unfortunately, it typically carries a premium price. This may be reduced with the bidding system in place. If you really want a Trane, then ask all the companies to quote Trane.

The ICP Group (United Technologies) makes Carrier units. These same people also make ComfortMaker, Day&Night, Bryant and Payne. You can expect Paine to be the lowest priced unit. It is considered a builders grade. All of the systems from this manufacturer are more or less reliable, though make sure that the unit you buy has standard parts.

It will make all the difference down the road.

Amana has taken over the production of Goodman Air Conditioners. Because of a less than perfect record in the past, Goodman has a great price and now there units are very solid.

You may also consider Lennox, Nordyne and York. These brands are fine.

Your real concern, however, should be who will install your unit and how will they do it. Even the top-of-the-line unit will not operate properly if it is not installed correctly. Once you have narrowed your bidders down to 2, make sure you find out how qualified the actual installers are. What is their training? What is their experience? For the money you are about to spend, it is more than fair for you to ask these questions.

Units must be installed correctly. It is easy and convenient to cut corners. A few shortcuts will cost you dearly in the long run, so make sure you are comfortable with the people who will actually do the work.

You can expect to pay around $5000 for a system to heat and cool a typical American 3 bedroom home. A real money-saving secret is to allow the use of a “scratch and dent” unit – as long as the complete warranty will still be valid. Let the

contractors who are bidding know that you would be ok with this.

So here is the plan: Get qualified bidders, tell them the specifics of what you would accept, get their quotes and narrow down to 2 for the final decision. Make your final decision based on the quality of the installers. You will be on your way to having a great unit installed at the right price.

Air Conditioning Maintenance

Air Conditioning Maintenance

by

gipedan

The average age of an air conditioner is 10 years; some units can run longer than that, some run with a much higher cost after 10 years. If not maintained correctly it can cost you double the operating costs without reducing comfort. Today s technology has allowed us to achieve better performance without sacrificing efficiency. In fact, today s models are much cheaper to run than that 10-year-old model gulping up your hard earned money.

I recommend to solve this problem of high energy bills is to upgrade to a Goodman 13 Seer Air Conditioning System through Yours By Design Heating and Cooling.

If for some reason you want to spend more money (up to 40%) than necessary and not buy the upgrade do yourself a favor and

Check and Clean Condenser Coil

Foreign material on the condenser coil reduces the system’s capacity to remove heat from the house so your air conditioning system must run longer, increasing energy consumption.

Check voltage and amperage on motors

Improper voltage an amperage can reduce significantly the life of the compressor, evaporator and the condenser motor.

Check and adjust blower components

Proper adjustment, cleanliness of blower and components are necessary for adequate air flow to assure proper capacity and equipment reliability.

Check condensate drain (clean if necessary)

A clogged drain can create considerable water damage, as well as affect indoor humidity levels.

Check operating pressures for proper refrigerant charge

Improper refrigerant charges either too much or too little could damage the compressor and could cause high electric bills through a curtailment of system efficiency.

Check air filters

A dirty filter can substantially reduce the air flow over the evaporator coil, resulting in inadequate cooling of your home. A Dirty filter could cause high energy usage and compressor damage.

Check thermostat calibration

An improperly calibrated thermostat will call for more or less cooling than desired. The former will cost more money, the latter will cost you comfort.

Lubricate all moving parts where necessary

Poor lubrication causes drag in the motor and drive shaft, thereby requiring more electricity to overcome resistance. The lack of lubrication can ruin bearings and burn out a motor.

Check safety controls where applicable

This is very essential for the proper protection of the unit!

Check for correct air flow

One way to assure maximum efficiency of your cooling unit.

Check all electrical connections

Resistance caused by loose connections will create excessive heat at the point, causing damage to the unit. Loose connections cause improper voltage to various components, making them either inoperative or causing eventual failure.

Check starting capacities

Assure that your system will start and operate when needed.

Bottom line all these can add up to your system costing you money.

Warning! These Checks should only be done by a licensed trained Contractor. Serious damage or serious harm can be a result of an unskilled person attempting to clean the air conditioning system. Call us today at 763-546-7377 for a HVAC maintenance plan. Your furnace and air conditioner will be glad you did.

For Air Conditioning Units

The temperature must be at least 68 to 70 degrees in order to do a proper clean and check

No Rain!!!

Any refrigerant (Freon) is an extra charge, depending on how much is needed.

To you comfort,

Dan
