The XR16 is a low-profile side-discharge air conditioning unit for split ducted systems. The unit is available in 1.5- to 5-ton sizes. It is designed for challenging applications, including zero lot-line situations, multifamily housing, and condominium units and row houses.
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.”
At Casa de Misericordia (House of Mercy) near Piedra Negras, Coahuila, Mexico, children who have been abandoned or removed from their home due to severe neglect or unsafe conditions are provided with a secure place, food, and a caring, stable environment. For the 30-40 children who call Casa de Misericordia home at any given time, that environment can now offer even greater relief, thanks to a donation from Friedrich Air Conditioning.

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.
On the heels of brand-new air conditioning product launches, LG Electronics is reinforcing its deep commitment to the future of the HVAC industry by introducing the “LG Technology Roadshow” — a unique LG mobile showroom on wheels — providing customers across the U.S. an opportunity for a hands-on experience with LG’s latest air conditioning technologies.
Testo Inc. announced its 2017 Refrigeration Spring Campaign. This campaign builds upon the immense success of Testo’s Smart Probe Refrigeration Kit and the 550 and 557 Smart Digital Manifolds, which now come standard with Bluetooth.
In a perfect scenario, the oil in a refrigeration or air conditioning system would stay inside the compressor’s crankcase to lubricate the compressor’s moving parts. However, because of ever-changing heat loads on the system and varying system conditions there is no such thing as a perfect system in the real world.
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).
