Energy transfer in an air conditioner

Energy transfer in an air conditioner is a process that is meant to happen. Air conditioner works on a thermodynamic system that is closed. The power that enters the closed space in this system which is maintained at a regular temperature at all times requires a higher amount of energy removal from the system. The increase in the output has an effect of the air conditioner removing that energy. This is achieved by the increase in the power consumption that is inverse to the efficiency times that the power was dissipated into the system. Almost all the air conditioners work at an efficiency that is greater than 100%. The electrical energy that serves as the input for air conditioners is of a higher thermodynamic quality than the thermal energy that is released as the output. The energy ratios of an air conditioner can be calculated with the help of formulae. There are minimum requirements that are set for the efficiency of air conditioners in some countries. This is denoted by the term SEER which stands for Seasonal Energy Efficiency Ratio. The energy efficiency of the air conditioner becomes better with high rate of SEER.

Chemical wash for air conditioners

Cleaning and maintaining an air conditioner in a good condition can be done in a number of ways. One of the most popular methods that are used to service an air conditioner is chemical washing it. They are known to people who read more on aircon repair. When an air conditioner is maintained in a good condition for a long time, the life span of the equipment will be high. This will also help keeping the equipment in a position that it does not consume a lot of power. Best aircon chemical wash is attempted when a normal wash does not give the desired results to an air conditioner. Some of such situations are a water leak, a foul smell coming out of the air conditioning system and also when the process of cooling the air takes a long time. In a chemical wash process, the whole unit of the air conditioner is dismantled and the parts are washed thoroughly with a chemical reagent. This includes the parts like the coils, filters and also the condenser. These parts are immersed in to the solution in order to dissolve any layer of dirt or dust that might have sedimented on the surface of these parts. The drainage pipes are also flushed with this solution. This is a basic technique that one can find when they read more on aircon servicing.

Keeping Building Simply Stylish

Building a shelter to live in has always been a vital instinct for human beings, and that instinct is still strong today. Building material suppliers are making a fortune out of this basic instinct as well because there are so many people who are focused on building the biggest, fanciest house possible as a status symbol or some such ideal. However, sand is starting to take root as an important building material in South Africa, especially for more economical projects.

Adobe buildings

The African continent is home to some of the most interesting, basic and functional shelter designs. Building sand has always been around in some form or other, along with clay and water. Adobe buildings make use of building sand, clay and water mixed together to form a surprisingly sturdy building material ideal for South African climates and conditions. Adding in some straw, grass and other fibres also adds in extra strength.

The mixture can be poured into moulds and left to dry, providing you with an affordable source of bricks for a new building. Then all you need to do is head to a building material supplier for paints, insulation materials and anything else you feel will help decorate your building.

Cob houses

Much like adobe buildings, cob houses make use of a mixture of building sand, clay and straw/grasses. However, where adobe is moulded into bricks cob houses are shaped straight from the mixture. This means that on top of a highly affordable house made from readily available building materials in South Africa, your home can be as funky and stylish as you want it to look (within structurally sound limitations, of course). You’ll just need to make sure you have a lot of time on your hands.

Sandbag bunkers

Building sand is useful as more than just an ingredient in mixtures. Building sand usually comes in polypropylene or burlap bags, which is perfect. You just get hold of loads of these (which will probably still be less expensive than the usual combination you get from building material suppliers) and stack them together securely into the shape of a hut. And as easy as that you have a house, hut or bunker (whichever you prefer) made entirely of sandbags. It isn’t very well insulated, but building sand is so freely available that this could be an extremely cost effective option especially for temporary or storage structures.

There is so much you can do with sand, and Sand Shifters is the ideal supplier of this and other building materials in South Africa. It’s right there in their name. Have a look at their blog to see what else you can do with building sand.
