HVAC Instrumentation and Controls

COURSE NO: M06-019
PDH CREDIT: 6
COURSE PROVIDER: A. Bhatia
HVAC Instrumentation and Controls
Course Highlights

This online engineering PDH course covers the fundamentals of automatic controls in the HVAC system. Emphasis is placed on the control principles, terminology, basic components, control devices and direct digital control systems. Numerous illustrations and examples have been included to enhance the understanding of the course material.

 

The HVAC systems are designed for peak conditions. Because these conditions prevail only for small period in a year, the HVAC equipment must operate most of the time at lean capacity. The function of the control system is to adjust the equipment capacity to match the load. Automatic controls are necessary not only to achieve the design conditions in the conditioned space but are also required for efficient operation of the HVAC system. The main parameters to be controlled in air conditioning system are temperature, pressure, humidity, air quality and thermal energy distribution.

 

It is important to note that the primary factor influencing the effectiveness of HVAC system is the proper mechanical design itself. The HVAC system must be properly designed to satisfy the process or comfort requirements. Only when this criterion is satisfied can a suitable control system be applied.

 

The 6 PDH online course is applicable to mechanical, electrical, controls and HVAC engineers, architects, building designers, contractors, estimators, energy auditors and facility managers who are interested in gaining a better understanding of HVAC instrumentation and controls. This course is aimed at the personnel who have some limited background in the air conditioning field or who may be having difficulty relating controls to air-conditioning equipment.
