Individualization of Microclimate Air Conditioning Systems in Residential Premises

Assessment of Propane in North American Residential Air Conditioning

Three unitary split systems were evaluated for use with propane as the refrigerant. These three systems were then compared to systems using hydrochlorofluorocarbon (HCFC) R-22 and hydrofluorocarbon (HFC) R-410A for environmental effectiveness. The propane systems included one using safety measures, another using propane with flame suppressant, and one using a secondary heat transfer loop to iso...

Effects of Architectural Somatic Variables on Mixed Air Conditioning Systems’ Efficiency in Industrial Buildings

Predictive control of multizone heating, ventilation and air-conditioning systems in non-residential buildings

In France, buildings account for a large part of the energy consumption and carbon emissions. Both are mainly due to Heating, Ventilation and Air-Conditioning (HVAC) systems. Because older, oversized or poorly maintained systems may be using more energy and costing more to operate than necessary, new management approaches are needed. In addition, energy efficiency can be improved in central hea...

Challenges and Developments of Subtropical Residential Air Conditioning

Energy Performance Comparison of Heating and Air Conditioning Systems for Multifamily Residential Buildings

The type of heating, ventilation and air conditioning (HVAC) system has a large impact on the heating and cooling energy consumption in multifamily residential buildings. This paper compares the energy performance of three HVAC systems: a direct expansion (DX) split system, a split air source heat pump (ASHP) system, and a closedloop water source heat pump (WSHP) system with a boiler and an eva...
