TASK 1 – ENERGY EFFICIENT AND SUSTAINABLE TECHNOLOGIES
1. EVAPORATIVE COOLING
One effective form of air conditioning, which is fitting for less humid states of Australia and is based on the evaporation of water, is evaporative cooling. When water evaporates, this system absorbs warmth from its surroundings, which then cools the surrounding environment down. These sorts of units are usually mounted on roofs. Evaporative

This is because refrigerated cooling results in dry air and uses chemicals, which may harm the environment if released into the atmosphere. Evaporative cooling is a very healthy way to cool because it replaces stale air with clean, fresh air many times an hour.
2. GAS DUCTED HEATING
This is a gas fuelled heating system, which produces heat to more than one room. This system can also cool your home. This system draws air from inside homes within a heat exchanger for immediate heating and circulation through openings in floors or ceilings of houses. Gas ducted heating has many positives one being that it is highly efficient and cost effective. Also it requires minimal maintenance.
Floor registers are often positioned near outside walls to allow heat to fully flow back through your home. Ceiling registers are placed centrally in a room or between the center and external walls. Benefits for the house is that this system is designed to heat every room, meaning no cold spots in the house, resulting in a much more comfortable home. It is also highly efficient is all weather which is different to reverse cycle systems that are likely to lose efficiency when the temperature really drops outside but ducted gas systems remain unaffected. This reduces
Most people depend on their air conditioners. It is the only way to stay cool when you are inside of your home or office and the temperatures are soaring into the 90s and beyond as it often does in Fort Meyers and other areas of south Florida. The thing is, most older air conditioning units are not able to keep up with the heat as well as most people want for them to. Also, many people are now having to deal with the R22 Freon phase out that is taking place and it is causing a lot of people to suffer in misery.
Electric and ceramic heaters dry the room air, but Delonghi EW7707CM which is a radiator heater keeps the moisture in tact, which is a huge advantage.According to Delonghi, their patented thermal chimneys reduce surface heat much better than other space heaters.The heater does get warm even with the patented thermal chimneys, so it will be better to keep it away from the reach of children (especially those curious ones).
The need for a ceiling fan however is apparent. A ceiling fan could help to cool and soothe the homeowner by helping to circulate air and provide air current control. Air can become so still and stagnant when it doesn’t move! Two or three ceiling fans in a home could really make a difference! Almost anyone would desire a cooling fan, which could save on the electric bill in the summer. An additional benefit is a little known fact: most people don’t know that they could benefit from a ceiling fan in the winter also. By reversing the direction on the ceiling fan, pulling the warm air down from the ceiling into the room, the fan can help to provide warmth for the room and reduce the heating
Most people are looking forward to the warm summer weather for several different reasons. But no matter how many people have been longing to enjoy those nice, sunny days that are right around the corner, at some point they will want to escape the heat. When the heat becomes too much and people decide it's time to cool off, an air conditioner is one of the many ways they will accomplishment this goal. That is only if they have prepared for the summer and gotten their air conditioner replaced or repaired.
The concept of using radiant and convection heat for comfort has been around since early man. People chose south facing caves because the sun would warm up the rocks during the day and radiate the heat into the cave at night. The flames from a fire also gave off radiant heat. Technology has developed to control radiant and convection heat. Radiant heating and cooling (RHC) systems utilize the surrounding surfaces as heating and/or cooling sources. Generally, RHC systems are systems that radiant heat transfers cover more than 50% of heat exchange within a specified space. Compared to all-air systems, which depend on convection only, the RHC system provides heating and cooling by the combination of radiation and convection in a building. There are three types of radiant floor heating systems. The first type is a radiant air floor, where the air is the heat-transferring medium. The second type is electric radiant floor. The last type is hydronic radiant floor, which uses hot water.
When you feel the intake of air in your home or hold your hand up to the air vent, you feel air circulating rapidly. There is also a substance known as coolant circulating throughout the closed system. The workings of this system allow the air conditioner to cool your home.
Forced air heating systems use a furnace to heat the air, and the warm air is circulated throughout the home. Traditional heating methods have many drawbacks, and many people are opting for radiant heating. Radiant heating uses water, and the heat is generated in the walls and floors. An HVAC technician can professionally install radiant floors in your home.
Hidden behind your walls and generally ignored, your air ducts serve as central pathway that delivers warm and cool air throughout your home. When attached to your HVAC systems, the air ducts and vents transfer the air from these systems throughout your home all year round.
Energy: Time and money will need to be put into maintaining your evaporative cooler, and that will require energy on your part. Again, whether you perform the maintenance yourself or hire a professional, you'll still have to have the energy to get things done and ensure your cooler is ready for use and will last the summer. Of course, this shouldn't be a reason you decide to not purchase an evaporative cooler because many other cooling options will still require maintenance and energy.
Air Conditioners make your vehicle cool. It filters air to be cleaned and regulates the air's humidity inside your vehicle for comfortable driving. It helps your vehicle cool down thus transferring heat from indoors to outdoors. A refrigerant, commonly known as a freon flows through a coiled copper tube which absorbs heat then transfers it to the condenser coil from the outside for dispersal. There is also a fan that helps cool the coils which act as an exhaust.
An air conditioned home is something that people often take for granted. After all, cool, comfortable temperatures usually require nothing more than a simple adjustment of your thermostat. What too many people don't realize, however, is that your air conditioning unit has to do a great deal of work in order to make your home comfortable--and homeowners often make this job even more difficult with improper use.
Air Conditioning - Air conditioning is automatically reprogrammed to ensure that close after hours. Air-conditioning is programmed for use in energy-saving mode that consumes less energy. Air conditioning is normal for them to work in the best condition, which will help reduce energy consumption and contribute to sustainable energy.
This technology is far less commonly applied to refrigeration than vapor-compression refrigeration is the primary advantages of a Peltier cooler compared to a vapor-compression refrigerator are its lack of moving parts or circulating liquid, very long life, invulnerability to leaks, small size and flexible shape. Its main disadvantage is high cost and poor power efficiency. Many researchers and companies are
In actuality, well-designed, naturally-ventilated buildings lead to profitability in many ways. They have the potential to cut energy use of air-conditioned buildings in half .
People often turn to portable space heaters for help warming rooms when their primary home heating system isn't quite up to the task. Others prefer space heaters for the savings they provide by allowing you to heat only the rooms you use. There are many different types of portable heaters, all of which use slightly different methods to warm the space. Which one will work best for you depends on the characteristics of the space you will be heating. You should also take into account how loud the heater is when running and consider safety issues, especially if you have children or pets.
