Chilled Water vs. Solar vs. Standard: Which Is the Best?

A thermometer at the beachWith heat waves at record-breaking temperatures, more Australians have learned to invest in an air-conditioning system. What many do not know, however, is that there are different options available. A person’s choice can have an impact on energy savings, comfort, and ease of maintenance. Here are three of them:

Standard air-conditioners

Air-conditioning systems perform two functions: get rid of moisture to reduce humidity and cool the environment. Although four major components make up an AC unit, all of them work to complete a process called phase conversion. It is when the liquid with warm air transforms into gas with the help of a refrigerant. Then it comes back into a liquid form cooling the air through the compressor and the condenser.

Chilled water system

Standard air-conditioners are very popular, but they are not always the practical solution. For one, they can use up a lot of energy, which means they could cost a lot of money. They can also heat up.

For those who want to install an air-conditioning system throughout the house or in a building with many individual rooms such as hotels or offices, the chilled water system is a better option.

It comprises of two main parts: cooling tower and chiller. The basic idea is the chiller helps keep the water cool at 7 degrees Celsius. The water then passes through cooling coils found in areas that need the A/C. The tower, on the other hand, helps bring maintain the cold temperature of the condenser.

To make it more energy efficient, installing a hydraulic separator, which helps separates air and dirt particles, is necessary.

Solar-powered air-conditioners

Some homes also use solar-powered air conditioners, which may be passive or photovoltaic conversion. Besides being more sustainable, it also helps save money on energy costs in the long term.

But it is ideal for places that receive plenty of sunlight for most times of the year. Moreover, it has a very high setup costs, and maintaining it can be both time-consuming and even costly.

Which one is the best? It depends on the circumstance. Weighing the pros and cons is the surest way to come up with the right decision.
