This is an introduction to the design of heating and cooling distribution systems outside of buildings. It provides information about system selection, distribution media selection, and general distribution system design. Learn More>>
Overview Basic principles of air distribution as related to air device selection is fundamental knowledge that an HVAC engineer or designer should understand before selecting air devices. ASHRAE standards and codes have adopted criterion that suggests that air.. Learn More>>
Laboratories commonly use far more energy than typical office buildings, primarily due to the intensive ventilation required to address environmental, health, and safety concerns. Active chilled beam systems are gaining in popularity among laboratory designers... Learn More>>
This course teaches the following specific knowledge and skills: Be able to define indoor air quality, The common pollution pathways in a building, The four common air quality control strategies, The four technologies to remove contaminants from the air, The benefits of exposure control, How to address common air quality issues Learn More>>
The prime requirement in respect of the indoor climate in a building is that room temperature should be at a comfortable level, regardless of the weather conditions outside. As soon as the ambient temperature is lower than the indoor temperature, heat flows out... Learn More>>
Overview The most suitable fan for a particular application is dependent upon many factors. Initial cost, efficiency, operating and maintenance costs, speed, materials, space constraints, flow rate, pressure, temperature, cleanliness of the product and the range Learn More>>
The thermodynamic efficiency of a refrigeration system depends mainly on its operating temperatures. However, important practical issues such as the system design, size, initial and operating costs, safety, reliability, and serviceability etc. Learn More>>
In today's complex building structures it is imperative that the HVAC engineer have a basic knowledge of fire, smoke and combination fire/smoke dampers. Rated dampers are a crucial part of the HVAC and life safety system requirements. Rated dampers have been modifi Learn More>>
A chiller can be generally classified as a refrigeration system that uses either a vapor compression or absorption cycle to cool. Both the absorption and the mechanical compression systems have the evaporation and condensation of a refrigerant in common. Learn More>>
In large commercial and industrial systems, chilled water system serves as means to transfer heat from building spaces to the refrigeration system. Initially, when energy costs were low, constant volume and primary-secondary systems provided a stable and simple... Learn More>>
