Over the years, air conditioning units have become more efficient and technologically advanced. If your business is still running an older model cooling system it may be in your best interest to consider high-efficiency air-conditioning, which is designed to use up to 25% less electricity.

With high-efficiency air-conditioning units, condensers are made larger and compression ratios are altered. The air filters and cooling coils are also larger to improve the heat transfer process and they can reduce the velocity of air flow through the unit to ensure better cooling with less energy used.

Rather than traditional AC units, space cooling technologies have taken on entirely new applications and methods. Here are some examples of new cooling technologies.

Radiant cooling is an innovative system that uses chilled water pipes to distribute cooling throughout a building instead of a conventional system of chilled air and ductwork. This system relies on cool water pipes to absorb heat generated by people inside the building. This system is optimal for new buildings.


Energy management control systems (EMCS) use sophisticated computers, communication and sensors to control temperature, humidity and monitor energy usage. These controls can make just about any cooling technology much more efficient and save money spent on energy.

An EMCS can automatically control temperature and humidity in a building, and can turn off air cooling equipment temporarily during times when commercial buildings are unoccupied, such as night time or early mornings.

Another innovative technology is solar air conditioning, which is a passive system that runs off of solar energy. These units do not rely on the massive power consumption that generally comes from traditional cooling units. Instead solar cells work to power the cooling units and reduce overall energy consumption by converting heat energy from the sun into cooling energy for your building.

One of the more popular forms of passive design is a green roof system that incorporates rooftop to help to reduce air conditioning use by absorbing heat. A reduction in one per cent of the temperature of a roofing surface can remove five per cent of the demand for air conditioning electricity.

Solar collectors can also be used to provide energy for a building’s cooling system. This form of solar energy uses a glazed panel, a heat transfer circuit and a storage system including a heat exchanger. Hot water collected during the collection process makes steam, which cools the air.

With these new changes in cooling technology it has become much easier to cool down a space and keep it cool while conserving energy and saving money.
