“…Water vapor is absorbed by the lithium bromide concentrated solution which releases the heat of dissolution in the absorber. Dilute lithium bromide solution enters the generator and starts the next cycle. , Compared with the traditional absorption heat pump system, the ZCAHP system has comparable surplus heat recovery performance. The difference is the zero-energy consumption, which means that, in contrast with the traditional absorption heat pump system, there is no need for an additional driving energy source, such as natural gas, steam, or hot water.…”

The medium in the cooling circulation channel of the magnetic drive centrifugal pump will take away the heat generated by the magnetic eddy current and bearing friction in time to avoid the high temperature demagnetization phenomenon of the permanent magnets. Therefore, the reasonable design of the cooling circulation channel directly affects the stable operation of the magnetic drive centrifugal pump. In this paper, the heat exchange and temperature distribution in the cooling circulating channel of magnetic drive pump are studied by means of numerical calculation of fluid-heat coupling and external characteristic test. The temperature distribution and development law of the isolation sleeve clearance, the bottom of the isolation sleeve and the reflow hole are analysed emphatically, and the convection heat transfer coefficient distribution in the isolation sleeve clearance is studied.

“…Regarding hybrid sorption-compression systems, instead, only a few studies can be found in literature, as detailed in [16] and most of them refer to liquid absorption-vapour compression systems. Moreover, the vast majority of proposed models are based on steady-state thermodynamic evaluations [36], thus disregarding the discontinuous operation typical of adsorption systems. In this context, the main aim of the paper is to develop the first simulation model able to dynamically represent the operation of a hybrid cascading adsorption/compression chiller.…”

Hybrid sorption-compression systems are gaining interest for heating/cooling/ refrigeration purposes in different applications, since they allow exploiting the benefits of both technologies and a better utilization of renewable sources. However, design of such components is still difficult, due to the intrinsic complexity of the systems and the lack of reliable models. In particular, the combination of adsorption-compression cascade unit has not been widely explored yet and there are no simulations or sizing tools reported in the literature. In this context, the present paper describes a model of a hybrid adsorption-compression system, realised in Modelica language using the commercial software Dymola. The models of the main components of the sorption and vapour compression unit are described in details and their validation presented. In addition, the integrated model is used for proving the feasibility of the system under dynamic realistic conditions and an example of the technical sizing that the model is able to accomplish is given.
