A field test was conducted to evaluate the performance of installing a TESS into the supply duct of four packaged rooftop air conditioners. The following section details the specifics of the field
This review presents the previous works on thermal energy storage used for air conditioning systems and the application of phase change materials (PCMs) in different parts
For a conventional HVAC system, a 100-ton chiller must be specified to account for the peak demand, however, with the TES design depending upon the operating strategies a 50-ton chiller with 50% storage option shall provide the same results and meet the peak load requirements.
The air-handling unit fans accounts for significant operating energy to the tune of 30 to 50%. The low chilled water distribution to air-handling unit cooling coils provides lower temperature air for space cooling.
It has been seen that the air-conditioning cooling loads drives peak electric power demand. The air-conditioning accounts for almost 40% electricity consumption in US and as more and more building’s square feet and air-conditioned facilities are added up it has a definite impact upstream on the power plant load profile.
For a building demanding 400 tons of air-conditioning, the advantages are exemplified by the installations below. A traditional chilled water system using 44°F (6.7°C) supply and 54°F (12.2°C) return will require 2.4 gallons per minute (GPM) of chilled water for each ton-hour of refrigeration.
