Air Handler Equipment DDC Controllers

Air Handler Equipment DDC Controllers | HVAC Control

Air Handler Equipment DDC Controllers – These controllers will control an air handler once the wiring is completed. The panel is freshly mounted and waiting for the technician to run the piping and pull the wire from the control points. Other points, such as outside air, temperature sensors in piping or duct work, flow meters, actuators, or other control points can be terminated to these controllers and the data collected from those input points can be networked over the entire building automation system through the communication trunks. Included in this panel are: a terminal strip connection point for line voltage and control voltage, a transformer to step-down line voltage to the required control voltage of 24 volts which powers the controllers and a surge arrestor which is a requirement on many government jobs.

Air Conditioner Ductwork Leaks

Red Arrow Shows a Duct Work Leak in a Brand New Installed Duct System

A good consideration when replacing the air conditioning system is the duct work. Duct work seems to be the most ignored part of an HVAC system but is a very important consideration in this age of new technology and higher energy efficient equipment being developed and manufactured. You can have the most energy efficient engine but if its in an old 60 or 70’s model car your efficiency is going to suffer. The same is true with HVAC systems. You can have the most energy efficient compressor available on the market but if your duct work is leaky or your house or business is not properly insulated that high efficient system you just spent big dollars on is wasted money. For more insight on HVAC ductwork see the High Performance HVAC Ductwork Page.

Air Handler Components 3 | HVAC Air Handling

Air Handler Components: Hot Water Coil Heat

Air Handler Components 3Air Handler Components – Hot water coils inside of air handler units combine a boiler system or a special capacity hot water heater and forced air to provide forced-air heating. The concept is simple and used a lot in commercial and some in residential. Commercial systems almost exclusively use a boiler to provide hot water to the hot water coil inside the air handler unit while the residential systems use mainly special capacity hot water heaters to provide hot water to the hot water coil inside the air handler unit. On a call for heat a pump is energized to begin the circulation of hot water from the heating source to the coil. The air handler unit blower motor energizes and air begins to move across the coil. Heat is exchanged from the hot water coil to the air and the air is delivered to its appropriate destination through the ductwork.
