Dehumidification features are common on residential systems ever since the introduction of variable speed blower motors. The system is set up so that the blower can produce less CFM per ton when latent (humidity) load in the space is higher than the setpoint relative humidity. Slowing the blower increases moisture removal by reducing the sensible load on the evaporator coil and therefore dropping the coil temperature and surface dewpoint.

Lidl Leveling Playing Field with Walmart

This Lidl store in Greenville, S.C., sits across the street from a Walmart Neighborhood Market, just barely visible in the background of this photo taken during PG Editorial Director Jim Dudlicek’s visit last June.

More results are coming in on Lidl’s invasion of the U.S. grocery market, and the German hard-discounter is meeting the nation’s low-price leader head on.

While Lidl offered lower prices than Walmart on about a third of comparable branded items, its private label basket beat the Bentonville, Ark.-based mega retailer by nearly 25 percent.

That’s according to a price comparison test conducted by Kantar Retail, whose branded product basket at Walmart was cheaper than Lidl on only three items: a 12-pack of Bud Light, Crest toothpaste and a pint of Ben & Jerry’s ice cream.
