An Inexpensive Retrofit Technology for Reducing Peak Power Demand in Small and Medium Commercial Buildings
This article describes a low cost retrofit technology that uses collective control of multiple rooftop air conditioning units to reduce the peak power consumption of small and medium commercial buildings. The proposed control uses a thermal model of the building and air conditioning units to select an operating schedule for the air conditioning units that maintains a temperature set point subje...
متن کاملEffect of Condenser Air Flow on the Performance of Split Air Conditioner
Split air conditioning units are usually used for small and medium scale residential buildings. Therefore, more energy efficiency and lower cost are needed along with reliable control for the air conditioning units. An experimental investigation has been carried out to study the performance of a direct expansion air conditioning (A/C) unit having a variable speed condenser fan. The modulation o...
متن کاملVirtual Power Consumption and Cooling Capacity Virtual Sensors for Rooftop Units
Implementation of advanced controls and diagnostic features in small commercial buildings typically requires realtime monitoring of the energy flows, such as the power consumption and cooling capacity of rooftop units. However, these measurements are expensive and therefore limit the application of these advanced features. In order to lower the measurement cost, virtual sensing technology for r...
متن کاملSimulation of Thermal Distribution and Airflow for Efficient Energy Consumption in a Small Data Centers
Data centers have become ubiquitous in the last few years in an attempt to keep pace with the processing and storage needs of the Internet and cloud computing. The steady growth in the heat densities of IT servers leads to a rise in the energy needed to cool them, and constitutes approximately 40% of the power consumed by data centers. However, many data centers feature redundant air conditioni...
متن کاملDesign and Implementation of Air Conditioning System in Operating Room
The system is air conditioning system in operating room. The main objective of the system was implemented to provide air balance and temperature necessary conditions and to control airflow system for ventilation units in operating room. The operation room can be controlled with fuzzy expert system and describes the desired outputs. Input parameters such as temperature, humidity, oxygen and part...
