Northwest Territories and Nunavut HVAC 30 PDH Discount Package 1

This online engineering PDH course identifies the opportunities for improving the performance of the heating and cooling system based on the type of system that is in place.

Heating and cooling systems are the largest single consumers of energy in buildings. These systems condition the air within a building so that occupants are comfortable. Heating and cooling systems consist mainly of chillers, boilers, cooling towers, and pumps. There are central heating and cooling systems, and unitary systems that combine heating and cooling. Opportunities exist for improvement to both central and unitary systems.

This 3 PDH online course is applicable to engineers, contractors, designers and other technical professionals who are involved in the retrofit of existing heating and cooling systems.

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 provides a comprehensive description of the five prominent heat rejection methods as applicable to air conditioning systems.

One of the basic requirements of the air conditioning and refrigeration systems is to reject heat to the outdoors. Air conditioning chillers come in two different forms:

• An air-cooled chiller uses the flow of outside air across the condenser to remove or reject heat from the chiller. Air-cooled chillers typically have the condenser mounted on the roof or somewhere outside the facility while the evaporator can either be inside or outside the facility.
• Water-cooled chillers are typically 100 tons or greater and use water to remove the heat from the condenser. Water-cooled chillers are typically more efficient than air-cooled chillers. The condenser water is kept cool by a cooling tower, or water from the city main or well water is used. A water-cooled chiller will typically have the condenser and evaporator inside a facility while the cooling tower is located outside.

The range of chillers and associated heat rejection equipment is wide ranging.

This 4 PDH online course is applicable to architects, air-conditioning engineers, controls engineers, contractors, environmentalists, energy auditors and loss prevention professionals.

This online engineering PDH course provides information on the inspection, control and management of air leaks and presents the proper insulation and ventilation processes that make your home more comfortable and energy efficient.

The average family spends around half of its annual household energy bill on heating and cooling. This significant number can be dramatically reduced by making some simple energy-saving weatherization and insulation improvements to your home.

Air leaks through the ceiling, walls, foundations and other areas are typically the greatest sources of heating and cooling losses in a home. Insulation slows down the heat flow through a building’s envelope. Proper ventilation protects your home from moisture damage during winter and reduces heat buildup during summer. So, controlling air leaks, having the appropriate insulation and proper ventilation help in extending the life of your home, conserve energy, save money and increase your home’s overall comfort.

This online engineering PDH course reviews the above criteria in detail and provides guidance on the planning, layout and sizing of supply and return air ducts.

In air conditioning systems the duct is considered a static component of the installation through which air flows within the building, connecting all parts of the system. Ducts can be best described as arteries of the central air-conditioning system. These play an important role in keeping the whole HVAC system fit and achieving comfortable conditions throughout its life span.

Defects in a duct system can waste hundreds of dollars a year by forcing the HVAC system to run longer than necessary. Ductwork problems also make certain rooms too hot or too cold at different times of the year, while introducing dirt and bad odors into the forced-air system.

The objective of good duct design is to:

• Optimize duct size (manufacturing costs);
• Minimize duct system friction losses (operational cost);
• Reduce duct system acoustics (environmental costs); and
• Minimize air balance procedures (commissioning costs).

This 6 PDH online course is intended for mechanical and HVAC engineers, architects, building designers, contractors, energy auditors, facility managers, property and estate managers, O&M personnel, and other professionals interested in gaining a better understanding of sizing and designing duct systems.

This online engineering PDH course will help explain the complexities of HVAC design for offshore installations and how to go about carrying out the selection of a proper system and related equipment.

Oil & Gas (O&G) facilities are fraught with numerous challenges related to health and safety, logistics, economics, quality assurance and overall performance. HVAC design for such facilities needs special considerations not only to minimize the potential loss to capital investment but also to isolate the personnel from life-threatening environment. The main objectives of HVAC systems in O&G facilities include:

1. Maintain acceptable working and living environment for personnel and non - destructive conditions for equipment.
2. Prevent ingress of potentially explosive/toxic gas-air mixtures into non-hazardous areas, electrical switch rooms and equipment rooms.
3. Prevent formation of any combustible mixture and maintain an atmosphere where the gas/air mixture is kept below LEL during normal operation.
4. Provide dilution ventilation for all enclosed hazardous areas in order to reduce the risk from build-up of potentially explosive/toxic gases within these spaces.
5. Prevent smoke spreading and keep enclosed escape ways free of smoke in case of fire.

This 4 PDH online course is applicable to mechanical and HVAC engineers, process engineers, architects, building designers, contractors, energy auditors, facility managers who are involved in the design and installation of HVAC for oil and gas facilities.
