Originally designed to support an occupancy level of 850 people, the Arcbest corporate headquarters has grown to now have 1,085 people plus visitors. Ten percent of the people work at night, requiring 24/7 air conditioning. The increase in occupancy drove a need to introduce more outside air to maintain air quality. All of this outside air had to be conditioned, increasing electrical energy costs. In addition, the extra outside air caused draftiness on cold winter days, and, during the summer, the extra outside air flow through the air handlers resulted in some parts of the building getting too cool. 

In this month’s troubleshooting situation, you are dealing with a 4-ton split system, and the locale is a desert Southwest city. The customer in this case is the landlord, and they are working on the residence, getting it ready to rent after the departure of a long-term tenant. Their description of the problem is that the house “just won’t get comfortable.”

Mastercool’s new A/C System Analyzer is an all in one tool that not only calculates critical information for the air conditioning system but also diagnosis basic system problems. The LCD display leads the technician through basic test making service quicker and less complicated.

As the movement to legalize marijuana continues to take hold across the country, growers are beginning to seek out equipment that will help them maximize production. Until recently, there were no cooling and drying products specifically designed to optimize growing conditions for this agricultural product. Now, new technology is being engineered that can produce the right temperature and humidity conditions to maximize productivity and minimize mold and insect problems.

With the proper understanding of equipment and methods, refrigerant recovery can be faster and easier (not to mention much more legal) than venting.

Single phasing often occurs in an electric motor when one pair of points on its power contactor fails because of the destructive arcing that takes place each time these points open or close. This arc suppressor is designed for AC power applications that operate between 110-480 V and have a maximum allowable current of 235 A (rms).
