The methods of active temperature control mainly take the form of phase change temperature control , compulsory water temperature control. 主动温控方式主要包括:半导体温控、相变温控、强制恒温水冷温控等方法。 www.fabiao.net 2. This paper introduces test apparatus characteristics of phase change temperature...
Phase change materials allow thermal energy to be stored at constant temperature during their phase change. This study consists in coupling a photovoltaic system and a phase change material in order to should reduce the temperature of the photovoltaic surface and thus improve the electrical production...
and a system with an adjustable phase change temperature could be created, the efficiency could be significantly improved. This could either be performed through a controllable or adaptive system and would enable a dynamic change of the phase change temperature in response to user preferences, differe...
We analyze constant-voltage isotropic and non-isotropic scaling issues for phase change memory (PCM) based on electrothermal physics. Various analytical and simulation models of general and typical PCM cells that support the analysis is also provided. The analysis shows that the maximum temperature in...
phase change temperature; boundary temperature; thermal performance; evaluation index In the composite phase change material (PCM) building envelope, the matching relationship between the phase change temperature of the PCM and the wall's boundary temperature significantly affects the energy storage performa...
An application fitting phase change temperature and a large melting enthalpy are two obvious requirements for these materials. However, there is another important parameter: the cycling stability, in order to use the PCM as many times for storage and release of heat as required by an ...
