Cooling Load Calculations and Principles (M06-004)
Evaporative Cooling Design Guidelines (M06-014)
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 discusses some of the pertinent design issues and guidelines for evaporative cooling systems.
Evaporative cooling is a method of converting hot air into a cool breeze using the process of evaporating water. There are two essential requirements for evaporative cooling: 1) a wetted surface (supplied by filter pads) and 2) A source of moving air (supplied by a blower powered by an electric motor). The technology is a versatile and energy-efficient alternative to compressor-based cooling. Compared to air-conditioning which uses mechanical refrigeration, the evaporative cooling can fully satisfy building cooling loads using one-fourth the energy of conventional equipment.
The performance of evaporative systems deteriorates as the humidity increases. Consequently, evaporative systems are not suitable for the humid coastal regions. They are generally suitable for areas with dry summers (most of the western United States and other dry-climate areas worldwide. Evaporative cooling is also appropriate for spaces with high outside air ventilation requirements such as patios, auto garages, workshops, locker rooms, restaurant, kitchens, barns, green houses, kennels, agricultural areas, warehouses, docks or bays.
This 6 PDH online course is intended for engineers, architects, realtors, building owners, facility managers, interior designers, landscape architects, construction managers, lenders and educators and other professionals interested in learning about evaporative cooling design guidelines.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding what is evaporative cooling and where it should be used
- Understanding the principles of evaporative cooling
- Applying fundamentals of psychrometrics in estimating evaporative cooling requirements
- Learning the geographical locations that will benefit from evaporative cooling
- Understanding the components and types of evaporative coolers
- Learning how to calculate the cooling temperatures with direct and indirect evaporative cooling options
- Learning how to size evaporative coolers using sensible heat and air change methods
