Understanding the Star Ratings in Air Conditioning Systems in the Land Down Under

Developed countries are now implementing regulations on how their citizens should practice proper energy consumption. One of the rules being applied is the use of energy ratings or labels to determine the efficiency of household or industrial appliances. Air conditioning systems in particular, often have ratings to inform buyers about how much energy it would use to produce cool air.

In Australia, the Department of Environment and Energy enforces the Energy Rating Level for particular equipment and appliances. However, each one receives a different method of energy rating. A split system for air conditioning, for example, gets two sets of ratings, while a domestic refrigerator will only get one.

Here’s how to understand the meaning of energy ratings for air conditioners:

Star Rating

Most notable are the stars on the Energy Rating for air conditioners. However, unlike other appliances in Australia, air conditioning systems get two sets. One set is for cooling, while the other is for heating. Also, the more stars mean, the more energy efficient an appliance is.

This rating is used for non-ducted, single phase air conditioners intended for the household market. Some ducted systems provide a star rating though they’re not required to. To get the star rating for specific ducted systems, you can refer to the Registration Database of the Greenhouse and Energy Minimum Standards Regulator (GEMS).

Energy Consumption Figure

The energy consumption figure is divided into two: the capacity output (CO) on the left, and the power input (PI) on the right. CO is the amount of cool or hot air a unit produces, while PI is the required power for a unit to run.

Variable Output Compressor (VOC) and Demand-Response Capability (DRC)

Consumers notice these last two parts less. VOC indicates if an air conditioner has an inverter, which makes it a useful label on split system for air conditioning units. DRC meanwhile, indicates the capability of a system to participate in a voluntary scheme to reduce power consumption across the country.

Now that you know the meaning of these labels, you can choose the right air conditioning system for your home or office better.

Fight Climate Change with Commercial Air Conditioning Inspection

Carbon emissions have long been a serious concern for many developed nations, and it is no different in the UK. Between 2012 and 2013, carbon footprint went up by 3%. To reduce the problem, the country implements strategies like monitoring air conditioning among commercial buildings through inspection.

UK’s air conditioning inspection provides many benefits for commercial establishments — it allows them to adopt more energy-efficient systems, contribute to reducing carbon emission and improve the overall performance and value of their building.

If you are a manager or an owner of a commercial building, here are some of the things you have to remember about the inspection:

1. Effective Rated Output

Not all air-conditioning systems require regular inspection. It depends on the effective rated output, which should not be more than 12 kilowatts to be exempted. Take note that even if one unit scores less, if all of them sum up to beyond 12 kilowatts, they will still undergo checking.

2. Interval

The covered units must undergo inspection every five years. The first inspection differs from the effective rated output and the time the building started using their air conditioning unit. For example, an energy assessor should check if the unit was used on or before 1st January 2008 within its first five years. Systems with an effective rated output of over 250 kilowatts must undergo assessment by 4th January 2009.

3. Expectations

The scope of the assessor’s work does not include risk to public health or identification of installation hazards. The inspection does not solve your energy problems, but the assessor can provide recommendations to improve energy efficiency. These steps may include replacing your old systems or undergoing maintenance. Fortunately, you can now do these quickly as many commercial HVAC repair companies in the UK can provide such services on demand.

Although the inspection is necessary, following the suggestions is not mandatory. Nevertheless, if it is good for your building and the environment, there is no reason why you should not follow.

3 Habits That Can Aid Your Air Conditioner During Summer

Hot summer weather can affect your electricity bills due to the constant air conditioning needs of your home. The truth is it’s difficult to forego this, as you could compromise the health and well-being of your household.

Here are some easy and affordable ways to keep your utility cost down during summer:

Turn Them Off – Lights, washers, dryers, ovens and other electrical units and appliances add to the internal heat of your home during the day. Reserve washing the dishes to one go after dinner and do your laundry at night. Use the oven, microwave, hot pots or slow cookers in the evening. Light fixtures also emanate heat, so keep them off during the day. Instead of using the dryer, line-dry your clothes and maximize the summer sun’s heat.

Repair and Maintain – Keep your air conditioner clean and well maintained. Replace filters at least once every three months. Utahheatingandcooling.com recommends calling an expert in HVAC repairs and maintenance to check your unit regularly, even when it isn’t summer. Test for possible cracks and gaps in your home’s ducts, vents, sockets, switches, window panes, and door frames. Seal them up to keep warm air from entering.

Go Green – Plant trees, bushes and shrubs around your house, especially near the windows and the condenser to reduce the effect of the sun’s heat on the particular parts of your home. Add a few indoor plants to give a cooler and fresher feel. Replace your incandescent fixtures with LED and CFL bulbs since they give off less heat. Most importantly, turn off your cooling unit at night and open the windows instead.

No need to sweat it (pun intended) with these suggestions. You can be more confident now when turning on your air conditioner during summer. After all, reducing the abuse of your home’s cooling system, and your wallet, is possible.
