American Standard

Various HVAC Brands and Manufacturers

American Standard was formed in 1929 by the merger of the American Radiator Company and Standard Sanitary Manufacturing Company. In 1984, American Standard purchased the Trane brand. In 2007, American Standard split into 3 different companies. One of which would still manufacture heating and cooling products but would be named Trane. In 2008, Ingersoll Rand purchased Trane. Today, American Standard and Trane are sister brands of the same company, Ingersoll Rand.

Trane

Trane was founded by James Trane in Wisconsin and incorporated in 1913. The original invention was a vapor heating system. In 1923, James' son, Reuben invented the convection radiator which firmly established Trane's place in the industry. Trane was purchased by American Standard in 1984 and later acquired by Ingersoll Rand in 2008. Trane is known for its tagline, "It's hard to stop a Trane." Other brands in the Trane family:

The Impact of Inverter Technology on the HVAC Industry

Inverter technology has had a significant impact on the HVAC (Heating, Ventilation, and Air Conditioning) industry, offering several advantages compared to traditional HVAC systems. Here are some ways in which inverter technology has influenced the HVAC industry:

1. Energy Efficiency:

   • One of the primary advantages of inverter technology is its ability to operate at variable speeds. Traditional HVAC systems typically operate at fixed speeds, turning on and off to meet the temperature setpoint. In contrast, inverter-driven compressors can adjust their speed to match the actual cooling or heating demands. This results in improved energy efficiency and lower electricity consumption, especially during partial load conditions.

2. Precise Temperature Control:

   • Inverter-driven systems can modulate the speed of the compressor and fan to precisely match the required heating or cooling load. This leads to more stable and accurate temperature control, preventing temperature fluctuations and providing better comfort for occupants.

3. Reduced Start-Up Current:

   • Traditional HVAC systems often experience high inrush currents during startup, which can put stress on the electrical grid. Inverter technology minimizes these startup currents by gradually ramping up the compressor speed, reducing the strain on electrical systems, and extending the lifespan of components.

4. Quieter Operation:

   • Inverter-driven compressors operate at lower speeds when less capacity is needed, resulting in quieter operation compared to traditional HVAC systems that frequently cycle on and off. This is particularly advantageous for residential and commercial applications where noise levels are a concern.

5. Extended Lifespan:

   • The ability of inverter-driven systems to operate more efficiently and with reduced stress during startup and shutdown can contribute to a longer lifespan for the HVAC equipment. This can lead to lower maintenance costs and a higher return on investment over time.

6. Adaptability to Variable Loads:

   • Inverter technology allows HVAC systems to adapt to varying heating and cooling loads more effectively. This flexibility is beneficial in climates where outdoor temperatures fluctuate throughout the day or in buildings with changing occupancy levels.

7. Zoning and Individual Control:

   • Inverter-driven HVAC systems can support zoning and individual control of different areas within a building. This enables more precise temperature management for specific zones, optimizing comfort and energy efficiency.

8. Environmental Impact:

   • By reducing energy consumption and providing more efficient operation, inverter technology can contribute to lower greenhouse gas emissions and a smaller overall environmental footprint. This aligns with the industry's increasing focus on sustainability and energy conservation.

In summary, inverter technology has revolutionized the HVAC industry by improving energy efficiency, temperature control, and overall system performance. As technology continues to advance, inverter-driven systems will likely become even more prevalent, offering enhanced features and benefits for both residential and commercial applications.
