retrofit commercial air conditioners

ThermCo Energy Systems has been designing, testing, and installing our patented Thermal-Flow subcooling technology for over 15 years.

With over 100,000 large, inefficient, commercial air conditioners and refrigerant units still running today and with Utility Power Companies now utilizing smart meters to charge higher rates for High Demand Peek retro fitting with a "evaporative fluid cooling" tower will gain energy efficiency and save money, the environment, and by recycling, refurbishing the existing HVAC will reduce YOUR Carbon Footprint.

Demand Buster
Evaporative Fluid Coolers and Evaporative Condensers

It’s no accident that large commercial buildings utilize water-cooled air conditioning systems. Typically water-cooled systems have a 40% to 60% efficiency advantage over air-cooled air conditioning equipment. Water-cooled equipment utilizing Cooling towers, and Evaporative condensers have been utilized mainly in large commercial chilled water applications. This long proven technology does not exist in the light commercial applications that dominate the commercial market. Most light commercial buildings utilize roof top air-cooled "package unit", they are inexpensive and easy to install. The downside is that the units experience excessive heat due to the roof top installation.

The Urban Heat Island effect contributes to all of the radiant heat energy on the roof and makes the refrigerant units suffer and loses efficiency and capacity. In most sun-belt desert applications the air-cooled roof top units run at a net 6 EER using 2 kilowatts per ton/hour. A water-cooled roof top unit under the same desert conditions can run at a net 14+ EER using .85 kilowatts per ton/hour. Up to 60% savings over air-cooled systems.

ThermCo Energy Systems has developed a retrofit application (Evaporative Sub-Cooling) that converts air-cooled (HVAC) and store refrigerant roof top units into a Hybrid Air/Water cooled system. The reliable failsafe design will operate in the air-cooled mode only and in the more efficient air water cooled mode. The Thermal-Flow "Demand Buster" line of cooling towers (closed circuit and evaporative condensers) are the only units on the market that are light enough to be installed on a typical roof without structural upgrades.
