  • Primary energy consumption analysis of residential central air conditioning systems

    Energy saving potential in the AC (air conditioning) system is the focus of the researchers all over the world. In China, the main problems in AC systems are the high consumption and low utilization of energy. Enormous energy is consumed by the air conditioning systems of residential buildings, which makes the energy conservation more important. Currently many kinds of central air- conditioning systems are being used in residential buildings, each has different energy efficiency and will lead to different total energy consumption. So the selection of AC system schemes is of great significance to energy conservation. In this paper, based on an existing building, six schemes of residential central AC systems are presented, and their primary energy ratios are calculated respectively. The results show that the primary energy ratio of water loop heat pump system is the maximum, which will be the optimal AC system scheme for the residential buildings, and that of household gas- fired air conditioning system is the minimum, the application of which will not be good to energy conservation from the view of energy utilization.

  • Investigation of plug-in hybrid EVs (PHEVs) and their effects on power distribution systems in the NE and SW united states: Summary of a panel session presentation

    This paper will focus on showing the projected effects of PHEVs on residential loads in the Northeast and Southwest U.S. The Southwest studies, based in New Mexico, include consideration of central air conditioning (A/C) as a major load. The Northeast studies, based in Massachusetts, examine winter as well as summer load profiles with approximately the same PHEV charging requirements. Since truly commercial PHEVS are not expected to be available until late 2010, we have studied the literature and projections from manufacturers and others working in the PHEV to estimate battery capacities and charging power requirements. We have assumed 9-10 kWh per charge over periods of 5 hours. If a 7.0 kW PV system (ac rating) is employed in NM, this energy resource will provide most of the energy required for home use as well as charging two PHEVs. Additional information will be provided in the presentation.

  • An exploration of modeling in central air-conditioning intelligent control system for saving energy

    The complexity of system modeling is very typical in central air-conditioning, especially when considering the multi-working-condition sub-areas, multi- parameters and time delay problems, the complexity of mathematical model will greatly increase. Under the state, the question of how to obtain the correct model, whose error with the practical system is in the acceptable range, becomes more practical and theoretical meaningful. Through theoretical analysis and experimental conclusion, the paper simplifies the air- conditioning room to a single content plant with some self-balance capacity. The paper discusses the production of time delay and its effect. It considers the pertinence of temperature and moisture, at the same time the paper compares the intelligent optimal control algorithm with system PID control algorithm. These researches are very meaningful for the following work.

  • Determination of effective energy in buildings

    The phenomenon of low efficiency and waste is prevalent in public buildings. One of the reasons is the bad habit of people. There is no way to judge the level of waste ever since a long time ago. In order to analyze the level of building energy utilization to implement low energy building, this paper presents a concept of energy efficiency. It divides the energy of building into two parts. One part if effective energy, the other one is ineffective energy. The answer of effective energy divided by total energy is energy validity. Because the effective energy of building terminal is very difficult to measure directly, we can only use existing examination technology to calculate the parameters such as temperature, illumination and sensation to get change rate of time. Then unifying the behavioral characteristics of people, we gain the time of effective energy using. The ratio of both times can represent energy validity indirectly. In order to confirm this method, we have calculated the energy validity by using data of different buildings. The result indicates that the energy validity can reflect the level of artificial energy waste. It would be a quantitative indicator to obtain reasonable energy consumption of building.
