It is challenging and difficult for a conventional On-Off controlled single evaporator direct expansion (DX) air conditioning (A/C) system to deal with the variable latent load, unless complicated and costly supplementary measures to supply variable dehumidification ability are provided. Therefore, based on multi-evaporator air conditioning technology, a standalone DX based enhanced dehumidification...
This paper presents a temperature calibration equipment of micro-semiconductor cooling. Refrigerating capacity of the semiconductor cooling was tested with heat balance method. In equipment production, process of heat transfer from refrigeration film to temperature chamber is calculated and analyzed. Heat loss in heat transfer may be known by calculation of heat transfer process. When it is churned...
According to the real-time deviation between indoor dry-bulb temperature and set temperature, traditional PID control method of split air-conditioning is used to calculate the output power of split air-conditioning. Using the control method in a split air conditioning system, the rise time is often in contradiction with the overshoot of the control temperature when the temperature deviation is larger...
In this paper, artificial neural network is combined with wavelet analysis for the forecast of solar irradiance. This method is characteristic of the preprocessing of sample data using wavelet transformation for the forecast, i.e., the data sequence of solar irradiance as the sample is first mapped into several time-frequency domains, and then a chaos optimization neural network is established for...
