By 2020, it is expected that 20% of the energy supplies at home should come from renewable sources. Relying on renewables has a lot of benefits for homes and the environment. This expectation caused a significant change in the technology of HVACs. Now, HVAC companies are working hard to research how to create energy-efficient HVAC systems that have a renewable source and new systems that can run on an alternate source like geothermal or solar.
This article will introduce you to newly developed HVAC systems that have a slight change in their components that make them environment-friendly. These minor changes are only a step to a much greener and environment-friendly HVAC system in the future.
- On-command Hot Water Circulator
This product saves not only energy but also water. An on-command pump attaches in lines where the kitchen and bath fixtures are. It drains the cold water through a dedicated line then later gets heated. It has a line for cold and hot water so that it can deliver hot water anytime. It just drains the water that isn’t needed and uses it to be cooled or warmed when needed. The company that produced this is Taco, Inc. of Cranston, Rhode Island.
- Thermally-driven AC
A company in North Sydney, Australia called Chromasun, created a thermally-driven AC which is a cheaper alternative to standard ACs that run by electricity. This thermally-driven AC is solar-powered, and when the solar energy goes low, it can run on natural gas instead. Chromasun created their solar panels that will be able to absorb solar energy enough to work as a double-effect chiller. Some research suggests that their double-effect chiller system is more efficient and cooler than photovoltaic systems and at the same time eliminates energy costs.
- Ice-powered AC
Ice Energy, a company in Glendale, California, produced an AC that runs on ice. An Ice Bear, a device that freezes 450 gallons of water overnight, is needed to run this AC. Overnight, the tank of 450 gallons water freezes, making it available the next day. This tank of ice can cool a building up to six hours when switched to Ice Charging mode, but once the ice has completely melted and warmed, it continues using the building’s AC unit.
- Quiet-Duct Wrap
A quiet duct wrap is made by the Green Products Company and has been distributing this AC in the U.S. and other countries. They used recycled denim fabrics that contain no irritants. This duct wrap decreases the heat loss and increases that through the use of air ducts. This product does not use fiberglass which removes potential irritants and received a class-A fire rating for its tested resistance to fire.
- Geothermal Heat Pump
Geothermal HVAC systems have been making its name in the market since the 1940s. A geothermal heat pump uses the earth’s constant temperature to heat up or cool a room or building. During winter, the fluid in the earth loop absorbs heat and releases it to rooms. Meanwhile, during summer, it absorbs the cool temperature and like the previous progress releases the fresh air indoors.
