Thermal technology uses one of the most common forms of energy, heat, to achieve desired results. It deals with the heat transfer aspects of an HVAC system, focusing on how efficiently it manages temperature control within a building. This includes assessments of insulation, heat gain/loss calculations, system design, renewable energy, and potential energy-saving opportunities through advanced thermal technologies.
Energy efficiency is a top priority for homeowners and businesses alike. Emerging HVAC technologies are addressing this concern by offering energy-efficient systems that reduce environmental impact and help lower utility costs. HVAC systems incorporate advanced components such as variable-speed compressors and high-efficiency heat exchangers that optimise performance while minimising energy consumption. Thermal management uses tools and technologies to maintain a system within its operating temperature range.
Thermal technology for HVAC includes geothermal heat pumps, fuel combustion systems, and other HVAC equipment. Geothermal heat pumps heat and cool homes with the Earth’s constant temperature. Most geothermal systems are closed-loop, where water-based solutions run through tubing buried underground. Fuel combustion systems work well in cold regions and use natural gas, oil, or propane to create heat.
Thermal technology captures the sun’s heat to produce electricity. The PV cells can convert the sun’s light into electricity to power a household or building to some extent. This solar energy harnesses renewable power to reduce reliance on traditional energy sources.
Air conditioners utilise a refrigerant that pulls heat inside the home and expels it to the condenser. Ice-powered air conditioning stores thermal energy in ice during off-peak hours to provide cooling when needed, reducing electricity consumption. Inverter and dual inverter compressors improve efficiency and performance. Multi-split and zoned cooling systems offer customised climate control for different areas, and variable speed and zoned outdoor units provide precise cooling and energy savings. Water chiller heat pumps collect heat from the water to heat or cool the home. HVAC systems of the future are expected to use more of these technologies to reduce their energy use and environmental impact. This provides insights into select thermal technology companies.
