  • What are the benefits of evaporative cooling and what are the running costs?

    Is Evaporative Cooling Cost Effective?

    Evaporative cooling is a really simple system: taking warm, dry air cooling it and delivering it throughout your home.

    Energy Efficient Air Conditioner

    What that allows you to do is enjoy a modern lifestyle with your family. You’re able to entertain with al-fresco areas, while having your windows and doors open. The system blasts air through the house allowing you to keep the home opened up instead of bunking it down to keep the cool air in. This is very different to reverse cycle air-conditioning where the blinds are down, the windows and doors are closed, and you constantly have to remind the family to keep closing doors. It’s all about keeping it open and letting the air flow through the home.
    The other advantage is that being a really simple system, it doesn’t have refrigerant and it doesn’t involve complex engineering. It’s really a fan and wet blanket to make the air feel as though it’s cooler.

    Energy Saving & Cheaper to run Air Conditioner

    Being a simple system, and you’re only running a fan, a major advantage is that it’s much cheaper to run. So instead of running multiple appliances to achieve cooling as you would with a reverse cycle system, you’re just running a fan. This means you’re looking at a difference of about 20 cents an hour to run compared to about $1.20. Of course, this also depends on where you live and your energy service provider but the savings on electricity and on the running costs are enormous with evaporative cooling.
    Evaporative cooling offers a better cooling solution. It’s more humid so you don’t get dry, itchy eyes, and you don’t get itchy skin. It feels natural and comfortable to live in and makes your home more enjoyable for the whole family.

  • Am I Better Off Going For A Ducted Reverse Cycle Heating And Cooling Or Ducted Gas Heating With Reverse Cycle Cooling?

    Gas ducted heating is an efficient method of heating, especially in really cold climates. However, most homes in Australia need both heating and cooling, and this is where it gets a bit tricky. You want the benefits of both gas ducted heating as well as reverse cycle cooling, but what is the best way to have both?
    Some companies have systems that offer both heating and cooling that runs on the same principles and through the same controller as gas ducted heating. It can be zoned. You can set the temperature for each zone and get full flexibility, getting all the benefits of gas ducted heating without losing anything on the refrigerated cooling. It is really an immensely efficient way to heat and cool your home.

    Plan your Heating & Cooling System

    When looking at gas ducted heating with refrigerated cooling, it’s really important to plan it from the start because the air requirements for the refrigerated side for cooling is slightly greater than the gas ducted heating. So the duct, the vent and the whole system have to be designed from the start.
    To include the refrigerated cooling doesn’t mean you have to install both of them at the same time right after purchasing the unit. For instance, you may install the gas ducted heater at the beginning of winter and then the refrigerated cooling after a couple of months.

    Reverse Cycle Air Conditioning is Great in Warmer Climates

    Reverse cycle air conditioning is great in areas where you don’t have a huge heating demand –in areas where it’s fairly mild like the east coast of New South Wales up through Queensland. These areas generally don’t get as cold as below six or seven degrees.
    It’s fine to use reverse cycle for cooling but if you were to consider your heating requirements, you would want a product that is a lot more flexible. A ducted gas heating with reverse cycle cooling unit answers both your cooling and heating needs through its dual function. It’s all integrated into one controller and really delivers you the benefits of gas ducted heating in the cold months and also the benefits of refrigerated cooling in the warmer months.

  • What is Evaporative Cooling and how does it work?

    When seeking a cooling system for your home or business that is efficient, cost-effective and eco-friendly, an evaporative cooling system should be top of the list.
    With current concerns regarding the impact on the environment from technology plus the ever-increasing cost of living, an evaporative cooling system provides the superior alternative to air conditioning for creating an optimal healthy indoor environment throughout the whole house that is eco-friendly and bank account friendly.
    Conventional air conditioning works by taking air already inside of your house, passing it through a fan coil that cools it down and then delivers it back into the home. Because of this process, it is necessary to close all windows and doors so that the manufactured cold air will not escape, and you have to wait for it to get cold.

    Benefits of Evaporative Cooling

    Evaporative cooling, on the other hand, takes a more innovative approach. As the name suggests, the process cools air by evaporating water. This is done first by drawing in the surrounding fresh, hot or warm, dry air from outside your house via a cooling unit on top of the roof that is connected to a series of outlets, or ducts, placed strategically throughout the building. The warm is then filtered through wet pads or quilts, with the resulting evaporation cooling the air and increasing its moisture content. This technique allows evaporative cooling devices to be used even in open areas.
    So essentially, it takes in the warm air from the outside and the produced cool air is then blasted through the entire house via the ductwork into every room you want cooled and then out through open windows and doors, giving a steady supply of fresh, cool air.

    Evaporative Cooling is Cost-effective and Eco-friendly

    The benefits of evaporative cooling far outweigh those of traditional air conditioning. For a start, because of its design, it uses significantly less power per hour. This translates to bigger savings on utility costs, which not only means less impact on your bank account but also on the environment. Unlike air conditioning, evaporative coolers use no CFCs and thus do not release any into the atmosphere, which have been claimed to affect the ozone layer. In addition, it is more efficient, simple, and practical especially in areas with a dry, hot climate.

    Evaporative Cooling is the Healthy Choice

    Because evaporative cooling does not use recycled air like air conditioning does, you get only fresh, healthier cool air. The air is not dry, unlike air conditioning which tends to dry out the air and irritate some people’s eyes. Also, stale air in your home is completely replaced with fresh air. This means smells and allergens are not re-circulated; this is why sufferers of allergies or asthma will often choose an evaporative cooling system over air conditioning.
    One other reason Australians who love the great outdoors and hate the feeling of being ‘cooped up’ choose evaporative cooling over air conditioning is because doors and windows are left open, even in summer. In the winter months, the fans can be switched on when you want to remove winter stale air from your home as well — a great way to dispel those winter germs out of the house.

  • How efficient is an Evaporative Cooler?

    Evaporative cooling is definitely a cost-effective method of cooling. As opposed to running a condenser and a fan inside with the reverse cycle air conditioning, all you are running is a fan.

    But just how efficient is Evaporative Cooling?

    Evaporative cooling is like passing air across a wet blanket, causing an increase in humidity thus having a cooling effect. The more humid, the more moisture is in the air, the greater the cooling effect. In this respect, you would be looking at what would be the cost of about 20 cents per hour to run. As opposed to the reverse cycle air conditioning, this would cost you about a dollar and 20 cents per hour to run.

    Evaporative Cooling works best in Dry Climates

    Overall efficiency depends on the individual unit and your location. Say for example, if you are located in Sydney where it is hot and humid on that day, then you are not going to get any cooling effect by adding more moisture in the air when it is already humid. Whereas if you are located in Canberra or in Melbourne and on a hot, dry day, by adding some moisture in the air will bring a nice cooling effect.
    So for measuring the efficiency, it is not really efficient if you are not achieving your goal here – that is, a nice comfortable environment to live in. If you want to efficiently achieve positive results it will depend on installing the right type of system. However, if evaporative cooling is the appropriate unit to choose, it would not matter where you live and how much is the cost as it will always save you from spending too much on electricity.
