HVAC Fundamentals 24 PDH Discount Package

This online engineering PDH course provides a procedure for preparing a manual calculation for cooling load using CLTD/CLF method suggested by ASHRAE and includes two detailed examples. For more advanced methods such as TFM, the reader should refer to ASHRAE and other handbooks.

Heating and cooling load calculations are carried out to estimate the required capacity of heating and cooling systems, which can maintain the required conditions in the conditioned space. To estimate the required cooling or heating capacities, one has to have information regarding the design indoor and outdoor conditions, specifications of the building, specifications of the conditioned space, and any special requirements of the particular application.

Generally, heating and cooling load calculations involve a systematic and stepwise procedure, which account for all the building energy flows. In practice, a variety of methods ranging from simple rules-of-thumb to complex transfer function methods are used to arrive at the building loads.

This 6 PDH online course is applicable to mechanical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding in cooling load calculations and principles.

This online engineering PDH course provides an overview of psychrometrics and suggests how a better understanding of psychrometrics will improve air conditioning design and selection of equipment.

Psychrometry is the study of moist air. It is significant in terms of thermal comfort and is a major consideration in design of air conditioning systems. Air conditioning engineers use the psychrometric chart to predict changes in the environment when the amount of heat and/or water in the air changes. A psychrometric chart provides a convenient way to look at the air conditioning processes and it will answer why heated air can hold more moisture, and conversely, how allowing moist air to cool will result in condensation.

This 5 PDH online course is applicable to students, mechanical and HVAC engineers, process engineers, architects, building designers, contractors, energy auditors, facility managers who are interested in gaining a better understanding of psychrometrics.

This online engineering PDH course contains a compilation of almost 1000 bits and pieces of HVAC terminology, definitions and/or descriptions that will help resolve ambiguities in common usage of terms in normal interactions of people, infrastructure and environment. The compilation is arranged in an alphabetical order for easy referencing. The detailed description can be traced in handbooks and the web sites. This course document is a constant work in progress and your feedback is always welcome in an effort to continually update it.

This 5 PDH online course is aimed at mechanical, electrical, controls and HVAC engineers, architects, building designers, contractors, estimators, energy auditors and facility managers and other professionals who plan, design, construct, manage and use the building services infrastructure.

This online engineering PDH course provides guidance on the measurement of the flow rate of a fluid flowing under pressure in a closed conduit. Several categories of pipe flow measurement devices will be described and discussed, including some associated calculations.

The closed conduit is often circular, but also may be square or rectangular (such as a heating duct) or any other shape.  The other major category of flow is open channel flow, which is the flow of a liquid with a free surface open to atmospheric pressure.  Measurement of the flow rate of a fluid flowing under pressure, is carried out for a variety of purposes, such as billing for water supply to homes or businesses or, for monitoring or process control of a wide variety of industrial processes, which involve flowing fluids.

This 4 PDH online course is intended primarily for mechanical, civil and chemical, environmental, and industrial engineers.  Someone completing this course will gain knowledge about twelve different types of meters for measuring fluid flow rate in a closed conduit.  They will learn about typical calculations for differential pressure meters and pitot tubes.  They will learn the general principles of operation for each type and general advantages and disadvantages of each.

This online engineering PDH course provides an overview of absorption refrigeration technology. The aim of this course is to provide the working principle of absorption systems, types, applications, and economics of absorption refrigeration technologies.

The key feature of absorption cooling equipment is that it produces cooling by using heat energy as an input, rather than by using mechanical energy. The heat source is usually delivered via steam, hot water, or direct combustion. Compared to electrically powered chillers, they have high capital cost but these excel in operation where cheap, high grade heat or waste heat is readily available. These chillers do not need ozone-depleting refrigerants and many countries have begun identifying these machines as an energy and environmentally friendly equipment. Some states and utility companies provide subsidies and incentives such as tax rebates and higher depreciation. Absorption chillers can deliver from 25 to 2000 tons of refrigeration.

This 4 PDH online course is applicable to HVAC engineers, facility engineers, architects, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.
