HVAC Applications 30 PDH Discount Package

This online engineering PDH course provides an overview of various TES technology options and discusses their inherent pros and cons.

 

Thermal energy storage (TES) system is a load shifting strategy for creation of cooling to off-peak hours. In a TES system, a storage media is cooled during periods of low cooling demand and the stored cooling is used later to meet air-conditioning load or process cooling loads. Operating refrigeration chillers at night and displacing energy use from peak (day time) to off-peak periods when the energy is at a lower cost is the primary objective of TES system.

 

As a proven technology, chilled water or ice thermal storage systems supply the desired reliability for high air conditioning availability during peak hours and can substantially cut operating costs and reduces capital outlays when systems are suitably designed. It offers building owners the potential for substantial operating cost savings by using off-peak electricity to produce chilled water or ice for use in cooling during peak-hours.

 

This 4 PDH online course is applicable to architects, air-conditioning engineers, controls engineers, contractors, environmentalists, energy auditors and loss prevention professionals. It is assumed that all the readers know the basic functioning of the air conditioning system.

This online engineering PDH course presents the basics of gas fireplaces and briefly describes their different types, venting systems, efficiency ratings, ignition and controls, as well as their heat exchange and transfer. It also describes what to look for in a safe, energy-efficient gas fireplace as well as the problems that can be encountered with certain technologies. This course also provides information about where to locate the fireplace for maximum benefit and efficiency.

 

Changes in the way houses are built and renovated have made most contemporary homes incompatible with conventional wood-burning fireplaces. Most notably, the increased insulation and improved air-tightness of today's homes run counter to the large amounts of air required by conventional wood fireplaces. Such fireplaces are also extremely inefficient and produce high levels of harmful emissions, which pollute outdoor air and can have dangerous effects on indoor air quality. Some new fireplace designs offer a safe, energy-efficient and environmentally friendly alternative to conventional wood fireplaces.

 

This 3 PDH online course is applicable to engineers, architects, designers, contractors, homeowners, and gas fireplace manufacturers.

This online engineering PDH course presents an overview of commercial heat pump water heaters (HPWHs) applications. In today's industry, HPWH's are viewed as an effective and efficient method to provide hot water for commercial buildings. The system uses a water-heating heat pump to move heat from a cool reservoir, such as air, and transfer this heat into water. In addition this course illustrates the benefits and energy savings behind this technology, explains how to properly size an HPWH system and highlights the costs associated with the installation of HPWHs.

 

This 2 PDH online course is applicable to mechanical engineers, designers, contractors, building professionals, and all personnel interested in gaining a better understating of HPWH.

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 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 presents the best practices for a high performance data center utilizing the following systems: air management, air-side economizer, centralized air handling, cooling plant optimization, direct liquid cooling, free cooling with water side economizer, humidification controls alternatives, power supplies, self-generation and uninterruptable power supply systems along with a case study/benchmark findings for each of the above systems.

 

Data centers can consume 25 to 50 times as much electricity as standard office spaces. With such large power consumption, they are prime targets for energy efficient design measures that can save money and reduce electricity use. But the critical nature of data center loads elevates many design criteria -- chiefly reliability and high power density capacity – far above efficiency. Short design cycles often leave little time to fully assess efficient design opportunities or consider first cost versus life cycle cost issues. This can lead to designs that are simply scaled up versions of standard office space approaches or that re-use strategies and specifications that worked “good enough” in the past without regard for energy performance. The Data Center Design Guidelines have been created to provide viable alternatives to inefficient building practices.

 

The 6 PDH online course is intended for mechanical, electrical and computer engineers, as well as architects and any other technical personnel interested in gaining a better understanding of energy savings in data centers.

This online engineering PDH course presents a detailed discussion on the key concepts and practices relating to data cooling technology as well as air flow practices that improve conditions for IT equipment and reduce overall HVAC energy consumption.

 

The basic physics of a data center is that electricity is converted to heat. Equipment in the data center expends power, generating heat, requiring air conditioning and ventilation equipment to keep them cool and running well. If the temperature rises too high, equipment will begin to malfunction or become damaged; as the internal components begin to swell and pull away from each other (or simply burn-up). The cooling system is also required to adjust the humidity of the air and to remove particles. Depending upon the climate at a data center's location, moisture may need to be added or removed. Similarly, the types and amount of particles to be removed from the air are determined by the location and external events.

 

Data center cooling is a highly specialized area that uses precision cooling equipment that differs from the conventional comfort equipment. The combination of heat and the high sensitivity of electronic components in data center environments demands maximum availability and performance of the cooling equipment. Precision cooling systems have been designed specifically for this purpose.

 

This 5 PDH online course is applicable to mechanical engineers, electrical engineers, HVAC consultants and engineers, architects, O & M professionals, facility managers, estimators and general audience seeking to gain a better understanding of HVAC cooling systems for data centers. No specific prerequisite training or experience is required.

This online engineering PDH course discusses the HVAC design considerations for corrosive environments.

 

Many emerging HVAC markets have a majority of their populations located in coastal areas.  This leads to an increased number of air conditioning applications located in potentially corrosive environments. Environmental factors such as salt mist in sea side locations, add to the corrosive environments. It's not hard to see that HVAC equipment especially cooling and condenser coils are under threat of accelerated degradation. Corroded HVAC coils not only diminish the heat transfer but also increase the operational costs and the maintenance bills.  Prevention is much cheaper than replacing coils or the entire system.

 

Other than the HVAC equipment, the indoor space equipment is also susceptible to corrosive effects. Over time, even extremely low levels of Airborne Molecular Contamination (AMC) in the parts per billion can cause permanent damage to the sensitive electronic equipment, switchgear equipment, machinery and even the structural elements. Failure to protect your assets may have costly ramifications.

 

This 3 PDH online course is applicable to HVAC engineers, controls engineers, architects, contractors, environmentalists and loss prevention professionals who are interested in gaining an understanding in designing HVAC system in corrosive environments.
