Australia is considered as one of the hottest countries in the globe, with temperatures in Adelaide hitting as high as 46.6C during heat waves. Because of this, air conditioners can be found in almost every Aussie home. And with high cooling demands come high running costs for Richmond air conditioning Adelaide systems. It’s worrisome to think that comfort comes with a high price tag. Good thing there’s solar air conditioning that could mitigate the running costs of ACs.
What Are Solar Air Conditioning Systems?
A solar air conditioner is a heating and cooling system that uses solar power instead of electricity from the national power grid.
Richmond air conditioning Adelaide systems that run on solar power have a considerable upfront installation cost. However, they are a lot cheaper to run than those conventional models and are sure to save you thousands in operating costs in the long run. Solar energy is a great way to lower your household’s electricity bill and carbon footprint.
There are two major types of solar air conditioners, and they are:
Conventional Solar Powered Cooling System
This type of solar air conditioner uses a standard vapour compression refrigeration cycle to cool the house or office building. It’s the typical air conditioning system found in most homes and buildings but runs on power generated by a solar power system instead of the electricity grid.
Open Loop Cooling System
Also known as Dessicant Cooling, this type of solar air conditioning system is newer and less common but is more cost and energy-efficient. Open-loop solar air conditioners operate by using solar energy to heat a hot water tank. The hot water is then used to heat or cool the home. For heating, the water produces hot air to warm the room directly. For cooling, the hot air is used to dry out a cylinder that removes excess moisture from the air flowing in an adjacent chamber. After that, the dried air is pumped through a cooler, and then circulated around the house.
Are Solar Air Conditioners Cheaper to Run?
Both the solar refrigeration air conditioner and open-loop cooler require electricity to run – the former uses it to operate the compression and circulation of the refrigerant while the latter uses it to run the cooler for the dry air. However, they use less power compared to conventional air conditioning systems.
Between the two types of solar air conditioning systems, open-loop coolers require significantly lower running costs because it only needs to power the evaporative cooling system. On the other hand, the conventional solar-powered cooling system needs to compress and expand the refrigerant during cooling cycles constantly.
