Trend report: Air conditioning


Our bodies cool off by three basic methods: radiation, perspiration, and convection. Radiation occurs when heat radiates across space; warmth tends to flow to cooler material, including the air. Perspiration is the body’s natural cooling mechanism, as it carries away heat and cools further as it evaporates. Convection is where body heat is carried away by moving air.

All three of these processes are helped by ventilation and cooler air. We depend on our air conditioning in the heat of summer when a fan alone isn’t much help. Over the years, these cooling systems have become increasingly complex. Here are several air conditioning trends you might want to keep in mind if you want to upgrade your HVAC system.


  1. Energy Efficiency

This is always important, but as technology advances newer systems become more efficient. More efficient cooling not only helps lower electric bills, but the federal government has been providing tax incentives for installation of high-efficiency systems. These incentives are due to expire in 2016. Incentives can be referenced at this site searching by your Louisville-area zip code: ( .While more are likely to come, this may be just the right time to upgrade old AC units to a more modern, more efficient version.


  1. The Internet of Things

You may have heard about the increasing demand for appliances that are Wi-Fi enabled to communicate with smart devices and the Internet. AC systems are becoming part of the trend. For instance, you could turn up the AC at home when you leave work on a hot afternoon and find the house nice and cool when you arrive. These smart appliances are also able to store data and send alerts that make them so much easier to maintain, diagnose, and repair.


  1. Sub-metering

Electric utilities continue to struggle trying to meet growing demands on the power grid, particularly in summer months when air conditioning systems are running almost constantly. Thus, energy companies have turned to rate structures that charge more during periods of peak usage. Either the consumer finds ways to conserve energy or faces rising utility bills.

This particularly affects businesses in the Louisville, Kentucky area who depend on both equipment usage and building comfort throughout the day. One growing solution has been installation of sub-meters to track power usage at the point of use. This allows building managers to limit use of high-demand machinery and processes at hours of peak use in order to maximize energy conservation and cost savings.


  1. Integration

For both high-end homes and commercial facilities, the trend has been a comprehensive system that covers lighting, HVAC, water, security, and more, monitored and controlled from a central computer system. This allows property owners to track and strategize resources use while providing a convenient means of controlling whole-house consumption. As the trend catches on many new constructions are incorporating these smart systems that can lead to cost savings well worth the investment.

  1. Modulation

Modulation designs can optimize compressor performance and allow air conditioners to perform more efficiently at a range of temperatures. The system capacity changes to meet demand, thus reducing energy consumption. Modulated systems have many benefits, including more control over humidity and ambient temperature, as well as being more reliable and efficient. Another approach is “tandem” systems having two or more compressors to provide continuing capacity modulation.
