Hybrid HVAC system uses improved ground-source heat pumps
The GeoColumn hybrid HVAC system claims to improve upon two proven, but not always perfect, heating and cooling technologies.
Another product of the race between rising energy costs, global warming, and rapidly improving technology is the GeoColumn, a hybrid HVAC system that claims to improve upon two proven, but not always perfect, heating and cooling technologies.
According to Construction Week Online , GeoColumn offers the benefits of direct-exchange ground-source heat exchangers that produce heat from the surrounding earth without the costly and difficult excavation or deep-well drilling that these systems normally require. In addition, it also promises the efficiency of heat pump systems, which frequently disappoint owners by failing to produce enough heat when temperatures fall too far.
Invented by GeoEnergy Enterprises , a start-up energy technology firm with a decade of ground-source experience, the GeoColumn is a self-contained ground-source heat pump that does not require ground water, water pumping, or anti-freeze agents to function. Unlike other ground source systems, it can be installed in a relatively small space for light commercial projects.
The GeoColumn comes housed in a sealed vessel. Inside this container, a gas heat-exchange medium circulates through coils of copper tubing submerged in ordinary, unconditioned water. The entire system is buried in a borehole 23 ft deep, which can be dug easily by light, truck-mounted drilling equipment.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
