HVAC - 90%+ Furnace Venting
 |
Warning! This could happen to you! Be careful about how you diagnose this problem. Your ears may deceive you. Rely on a simple level to pinpoint this issue. The circuit board will tell you that the pressure switch is the culprit. You might suspect a blockage in the combustion air supply. Listen for the telltale sounds at the vent termination. Kinda sounds like a washing machine in the 'agitation' mode. The flue is actually obstructed by condensation that has pooled in a poorly pitched vent pipe. Diagnosis is more difficult when turns of the vent are hidden in walls or chases. Listen at the vent termination. That's the key. |

3D HVAC CATS Software
 |
CAD The user has a choice of two methods in creating the layout for his project with Ventilation Professional. The architect or engineer for the general one line layout of elements on his or her project may use the Trace Line method in the design stage. The Construction method is the layout required by Mechanical Engineers and Mechanical, Sheet Metal, and HVAC Contractors for the layout and coordination of their elements to be installed in the building project. Complex duct connections can be created automatically. Transitions, offsets, elbows and other complicated fittings can be created with a click of your mouse. Construction standards can be set up according to specific SMACNA or self generated specifications. In a short period of time, a realistic 3D drawing is created from a Trace Line drawing. Upon verification of the design as clear of structural elements and other elements installed by other trades, a file for the job is created. Information can be sent to your plasma table or coil line for production, or can be printed out for manual shop fabrication. Integrated calculation The user can assign air volume and pressure losses at the air distribution devices. A maximum velocity must be assigned to the system. The system pressure loss can now be calculated. The pressure loss values are calculated dynamically and therefore provide an exact result Piping Professional is used for designing pipelines, including chilled and hot water, air lines, vacuum systems and other <b>...</b> |

HVAC Variable Air Volume Controllers
 |
HVAC controls, including Variable Air Volume (VAV) controllers typically use either flow sensors to measure flow rates directly or differential pressure sensors to indirectly measure air flow. While, historically, differential pressure sensors have been the less expensive option, the economically priced Omron D6F-P MEMS Mass Flow Sensor, that delivers exceptional performance over pressure sensors, is now a viable option. |

HVAC High Pressure Sensor
 |
Describes the operation of the A/C (HVAC) or air conditioning high pressure sensor. This sensor is often the source of a NO-START condition. It sometimes shares the reference voltage with other sensors, such as the MAP, MAF sensor. This means that a short in this circuit will render the engine inoperative. See how it works in this training video. Get the scoop on this often ignored automotive sensor. |

HVAC Low Pressure Switch
 |
A quick look at an adjustable low pressure switches wiring. This switch is fitted on a Copeland scroll unit cooling a milk tank on a farm. The system runs on pumpdown cut out so its this switch thats responsible for deciding when the compressor should start and stop once the solenoid valve has operated. This switch has probably operated 20000 times in its 15 years. |
