Meeting residential ventilation standards through dynamic control of ventilation systems
چکیده انگلیسی

Existing ventilation standards, including American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) Standard 62.2, specify continuous operation of a defined mechanical ventilation system to provide minimum ventilation, with time-based intermittent operation as an option. This requirement ignores several factors and concerns including: other equipment such as household exhaust fans that might incidentally provide ventilation, negative impacts of ventilation when outdoor pollutant levels are high, the importance of minimizing energy use particularly during times of peak electricity demand, and how the energy used to condition air as part of ventilation system operation changes with outdoor conditions. Dynamic control of ventilation systems can provide ventilation equivalent to or better than what is required by standards while minimizing energy costs and can also add value by shifting load during peak times and reducing intake of outdoor air contaminants. This article describes the logic that enables dynamic control of whole-house ventilation systems to meet the intent of ventilation standards and demonstrates the dynamic ventilation system control concept through simulations and field tests of the Residential Integrated Ventilation-Energy Controller (RIVEC).


► In this study we develop a technique for using a dynamic ventilation controller to provide equivalent IAQ for a given ventilation requirement
► We use simulations do show how much energy can be saved using such a controller in three climates and for four different ventilation strategies.
► We provide a case study of one house with one particular controller strategy
► We show that peak power and total energy can be reduced using dynamic control of ventilation without increasing the relative dose of the occupants.
