During my 50 years in the HVAC trade, I have found that most technicians do not spend time learning about the compressor and the a/c system as much as they should. In their defense, they are simply too busy to take the time once they are out of school.
Some people say that the compressor is the key component, or heart, of an air conditioning system. And like the human heart, the compressor must be kept in tip-top condition to run the system efficiently.
Some of the most common problems and solutions for smooth compressor operation can be found in training materials and on-the-job experience. There is also another method for educating HVAC contractors and service technicians — getting answers straight from the manufacturers.
Manufacturers continue to make advances in compressors, especially when it comes to efficiency and ease of maintenance. This roundup highlights some of the latest offerings to hit the market, as well as those that will be available later this year.
Bitzer’s ECOLINE R-134a Octagon Reciprocating Compressors are optimized for use with R-134a. The ECOLINE series increases energy efficiency up to 20 percent compared to traditional R-404A medium temperature systems, the company says.
With the potential to reduce refrigeration-related energy expenses by up to 10 percent, the Copeland Scroll® K5 Refrigeration Compressor is designed for large refrigeration applications (7.5 to 15 hp), says the company.
A full lineup of fluid sensing and power products for residential and commercial HVACR applications is available. Residential components include condensate overflow switches and fluid level and flow sensors for a/c compressor coils; proximity and position sensors and reed switches for furnaces; and more.
The CoreSense™ Diagnostics electronics modules in Copeland Scroll® compressors unlock advanced capabilities in fixed-speed and two-stage compressors. Designed to help contractors troubleshoot residential air conditioning systems, the modules use the compressor as a sensor.
