Software Development for Cooling Load Estimation by CLTD Method

Traditionally, load estimating for air conditioning systems is done either by manual calculation or judgmental estimation based on experience of the air conditioning practitioner. While manual calculation is laborious, estimate based on judgment is liable to error due to gigantic, complex and dynamic nature of present day architectural designs. Load estimating through computer automation is lik...

Development of the Residential Load Factor Method for Heating and Cooling Load Calculations

The recent ASHRAE project, “Updating the ASHRAE/ ACCA Residential Heating and Cooling Load Calculation Procedures and Data” (RP-1199), developed two new residential loads calculation procedures: residential heat balance (RHB), a detailed heat balance method that requires computer implementation, and residential load factor (RLF), a simplified procedure that is hand tractable and suitable for sp...

Active versus passive cooling during neonatal transport.

BACKGROUND AND OBJECTIVE Therapeutic hypothermia is now the standard of care for hypoxic-ischemic encephalopathy. Treatment should be started early, and it is often necessary to transfer the infant to a regional NICU for ongoing care. There are no large studies reporting outcomes from infants cooled passively compared with active (servo-controlled) cooling during transfer. Our goal was to revie...

An online residential cooling load calculation program

This paper presents an online interactive program and how it can benefit students of engineering and architecture in the learning of residential cooling load calculation. This program is also helpful in the training of professional engineers and architects in the basic load calculations. It can be used as a stand-alone teaching aid or an add-on component for any online course dealing with air-c...
