Northwest Territories and Nunavut HVAC 30 PDH Discount Package 2

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 presents passive cooling systems which provide guidelines on choosing the proper technologies suitable to different situations.

Buildings are major consumers of energy insofar as their construction, operation and maintenance are concerned. It is estimated that almost 50% of the global energy demand is due to buildings with active HVAC equipment being the highest contributor. Thus, the energy conscious architecture has evolved to address these issues. It involves the use of eco-friendly and less energy intensive building materials, incorporation of passive cooling techniques in building design and integration of renewable energy technologies.

Passive cooling methods maximize the efficiency of the building envelope by minimizing heat gain from the external environment and facilitate cooling by air movement, ventilation, night cooling, evaporation, desiccant dehumidification and earth coupling to name a few. All these techniques require little or no input of electrical energy. Even when these alternatives cannot avoid the use of compressive cooling systems completely, their role can optimize the energy consumption and the peak electric load.

This 6 PDH online course is aimed at students, mechanical engineers, architects, facility managers, environmentalists, energy auditors and anyone interested in gaining a basic understanding of cooling systems.

This online engineering PDH course describes the hazards associated with batteries and highlights those safety features that must be taken into consideration when designing, constructing and fitting out a battery room. It is only for reference and anyone using this course should rely on state and local codes that may apply. Advice on specific ventilation rates required must be sought from the battery suppliers.

It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small. However, the concern is elevated during times of heavy recharge of the batteries, which occur immediately following a rapid and deep discharge.

Often the worst case scenario for dangerous hydrogen accumulation is underestimated. But dismissing such a critical safety issue is not a safe or responsible way to deal with it. Instead, engineers should be prepared to face the likely possibility of hydrogen build up, clearly identify the conditions when the risk is highest, and design systems that protect us from explosive levels in a fail-safe way.

This 5 PDH online course is intended for HVAC designers,architects, loss prevention engineers, facility maintenance personnel, environmentalists, energy auditors as well as consultants and contractorsinterested in gaining an understanding of cost effective ventilation.

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.

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 information on steam generation, types of boilers pertinent to engineering operations, and the various fittings and components commonly found on boilers.

The boiler is an enclosed vessel in which water is heated and circulated, either as hot water or steam, to produce a source for either heat or power. A central heating plant may have one or more boilers that use gas, oil, or coal as fuel. The steam generated is used to heat buildings, provide hot water, and provide steam for cleaning, sterilizing, cooking, and laundering operations. Small package boilers also provide steam and hot water for small buildings.

A boiler must also meet certain requirements before it is considered satisfactory for operation. The boiler must be safe and economical to operate, and it must be able to generate steam at the desired rate and pressure.
