Steam Distributing Coil

There are many terms used in the HVAC Industry. One that is often misunderstood is heat transfer. Wikipedia’s definition states that heat transfer is a thermal engineering discipline that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. It affects the measurement of heat.   The various heat transfer types are thermal conduction, thermal convection, thermal radiation, and the transfer of energy...

Hot Water Coil

The HVAC industry has many manufacturers of units that all have heating and/or cooling coils as an integral part of their package. There are also many free-standing coils in large built up systems and some are mounted in duct runs from a central station unit. What they all have in common is the presumption that all the coils will meet the designated performance. They do...

Condenser

  Almost all packaged A/C or split system units do not have a service factor for extra capacity. Even when new, these units may not yield the cooling BTUH capacity specified due to improper installation and/or incorrect load calculations at the inception of installation and startup. Consequently, as the system gets older and parts become less efficient, the system may lower its capacity to the point...

Outside Air Loads

HVAC and process heating/cooling must deal with the added tonnage created by using fresh air from outside. Most times, the requirement for fresh air is mandatory and can go from 10% all the way to 100 % of the system air flow. There are numerous rules and regulations written to eliminate air flow quality problems, including bacteria and other micro-organisms, that can cause health problems....

Condenser Coil

Although there are a myriad of reasons why A/C and refrigeration systems have problems, many of them can be traced back to the “condenser coil”. An inefficient coil can cause reduced space temperatures and adverse system pressures that often lead to major component problems, including compressor failures.   The title of this article comes from one of our oldest and best representatives, Marty Sternberg. Marty personally evaluates...
