20120260938 | METHOD OF DISSOLVING AND/OR INHIBITING THE DEPOSITION OF SCALE ON A SURFACE OF A SYSTEM - A method of dissolving and/or inhibiting the deposition of scale on a surface of a system comprises the step of bringing the surface of the system into contact with a composition. The composition can comprise from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition can further comprise from about 3 to about 15 parts by weight of an acidic component, which is different than the chelating component. The composition can further comprise at least about 60 parts by weight of water. Each of the parts by weight ranges above are based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and/or a corrosion inhibitor. | 10-18-2012 |

20100326470 | METHOD FOR CLEANING HVAC SYSTEM AND METHOD AND SYSTEM FOR VERIFYING CLEANING EFFECTIVENESS - A method of cleaning and a system and method of determining the effectiveness of a cleaning process for an HVAC system including a heat exchanger having a coil matrix. The coil matrix includes a plurality of rows of heat exchanging coils in which each adjacent row of coils is offset. The plurality of rows define channels extending through the coil matrix between an upstream side and a downstream side. The heat exchanger cleaning method includes applying a cleaning solution and a wet steam mixture directed into the channels. The effectiveness of the cleaning method is determine by a system and method which measures various operating parameters at the inlet side and outlet side of the heat exchanger both before and after the cleaning process. The system and method calculate a SEER rating using the total amount of heat removed by the HVAC system and the total power usage of the HVAC system. | 12-30-2010 |
