This paper presents an interactive finned-tube evaporator and condenser design program, EVAP-COND (ver. 3), which incorporates a computational intelligence module, ISHED (Intelligent System for Heat Exchanger Design), for optimization of refrigerant
While wireless sensor network technology has advanced in recent years, potential users of these systems in buildings still have concerns with their use. This report summarizes results of a literature survey and interactions with building industry
The BACnet standard [1] defines a communication protocol for information exchange between components of a distributed building automation and control system. The BACnet Communications Dynamically Linked Library (DLL) enables researchers to implement
The first version of HVACSIM+, which stands for HVAC SIMulation PLUS other systems, as introduced by National Institute of Standards and Technology (NIST) in 1985 as a computer simulation tool to simulate entire building systems [1]. Since then, the
Since its initial recognition in 1928 and commercialization in 1936, R-22 has been applied in systems ranging from the smallest window air conditioners to the largest chillers and heat pumps, including those for district cooling and heating. Individual
This paper quantifies the influence of copper (II) oxide (CuO) nanoparticle concentration on the boiling performance of R134a/polyolester mixtures on a roughened, horizontal flat surface. Nanofluids are liquids that contain dispersed nano-size particles

This paper presents a general methodology for developing a steady-state detector for a vapor compression system based on a moving window and using standard deviations of seven measurements selected as features. The feature thresholds and optimized moving
The efficient use of energy provides the double benefits of controlling both energy costs and greenhouse gas (GHG) emissions. The industrial sector comprises about one third of United States GHG emissions, so presents an attractive opportunity for
Building automation systems frequently monitor critical building information that would be extremely useful for emergency responders including the status of alarms, locations of occupants, temperature, and air quality conditions. Emergency response can be
