Accurate air-conditioning load forecasting is the precondition for the optimal control and energy saving operation of central air-conditioning system. However, the single forecasting method, such as autoregressive integrated moving average (ARIMA), grey model (GM), multiple linear regression (MLR) and artificial neural network (ANN), has not enough accuracy. In order to improve the accuracy of ...

A research project of the Hamburg University of Technology realizes an open cycle desiccant assisted air conditioning system based on renewable heat sources e.g. solar thermal and heat sinks e.g. shallow geothermal energy. Both advantages of the open cycle process are taken into account, the possible use of a heat sink at higher temperatures and the use of low calorific heat. Moreover, the tota...

Pinto, Jayant M., Paraya Assanasen, Fuad M. Baroody, Edward Naureckas, and Robert M. Naclerio. -Adrenoreceptor blockade with phenoxybenzamine does not affect the ability of the nose to condition air. J Appl Physiol 99: 128–133, 2005. First published March 3, 2005; doi:10.1152/japplphysiol.00857.2004.—The primary function of the nose is to warm and humidify air. We have previously shown that rai...

An intelligent control scheme for fan coil air-conditioning systems has been put forward in order to overcome the shortcomings of the traditional proportion-integral-derivative (PID) control scheme. These shortcomings include the inability of anti-interference and large inertia. An intelligent control test rig of fan coil air-conditioning system has been built, andMATLAB/Simulink dynamics simul...

Four simulation sub-models of four main parts; namely, photovoltaic/thermal (PV/T) collector, silica gel dehumidification unit, living space and air conditioning system, have been developed for a detailed transient simulation model for a hybrid PV/T solar air heating system for regenerating silica gel in air conditioning room. The models are explained along with algorithms for making quantitati...
