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....

Evaporator Coil

  Evaporator coils are a mystery to many technicians and engineers in the HVAC industry. Evaporator coils don’t have any movable parts, and a coil can have many different capacities based on what it’s fed from the refrigerant side of the closed refrigeration loop.   If a self-contained unit is used to provide air conditioning in a space, the evaporator coil will have been engineered to match the...
