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).
It’s the middle of summer and your customer, who can’t provide you with any helpful information about the history of this situation since they just recently purchased the business, is complaining that the temperature inside their small convenience store won’t get comfortable whenever the outdoor temperature gets over 90°F.
Although the function of compressors hasn’t changed tremendously over the years, the way they go about getting the job done has become increasingly refined and polished.
The Green Tech Line of refrigeration and air conditioning components is designed for use with natural refrigerants R-290 (propane), R-600a (isobutane), and R-744 (CO2). These high-quality, hydrocarbon (HC) and CO2-ready system components include valves, controllers, transducers, filter driers, and microchannel heat exchangers.
University of Alabama at Birmingham obtained an annual energy savings of $60,000 after Bernhard TME Engineering (TME) optimized the university’s district chilled water system. The chilled water is distributed to 48 buildings on campus to supply the air conditioning systems in the hot and humid southeastern U.S.
The European collaborative Poseidon project says it has developed a scanner that can detect Legionella bacteria in under one hour rather than the 10 days of cultivation and analysis normally required.
