Performance analysis of reciprocating magnetic liquefiers

One of the goals of the study of magnetic refrigeration is to find an alternative method of refrigeration capable of fulfilling cooling needs more efficiently than conventional refrigeration systems. To achieve this, it is necessary to produce component data, design and build test devices, and analyze the concepts. Published research has mostly covered three areas: (1) development of high performance magnetic working materials; (2) experimental studies of magnetic liquefaction and refrigeration; and (3) theoretical studies of magnetic systems. A calculation of efficiency for a general magnetic cycle indicated that magnetic refrigeration can potentially have an efficiency better than that of comparable gas refrigerators. Other studies indicated that high reliability can be obtained by magnetic refrigerators in the foreseeable future. This paper presents simplified models capable of predicting the performance limits of reciprocating magnetic liquefiers. Analyses of specific prototypes are carried out by taking into account the multiple mechanisms which affect the performance. The computer models developed in the course of the analysis are primarily used for preliminary screening of magnetic refrigerators and how they can be used in hydrogen liquefaction systems.     

An irreversible thermodynamic model for solar absorption refrigerator

A solar refrigerator is made of a solar collector and a refrigeration system. Real solar refrigerators usually operate between two limits, maximum coefficient of performance (COP) and maximum cooling load. A new model is presented to describe an irreversible absorption refrigerator, in which not only the irreversibilities of heat conduction but also those resulting from friction, eddy and other irreversible effects inside the working fluid are considered. The influence of these irreversible effects on the performance of an absorption refrigerator with continuous flow is investigated. The analytical expressions of the optimal refrigeration coefficient and the cooling rate of the refrigerator are derived. The predictions of the model are compared with semi-empirical cycle model of single-stage absorption refrigeration machines. The results obtained here can describe the optimal performance of a four temperature level absorption refrigeration affected simultaneously by the internal and external irreversibilities and provide the theoretical bases for the optimal design and operation of real absorption refrigerators operating between four temperature levels.     

Comparison of the optimal performance of single- and two-stage thermoelectric refrigeration systems

The cycle models of a single-stage and a two-stage semiconductor thermoelectric refrigeration system are established, based on non-equilibrium thermodynamics. They are used to derive the general expressions of three important performance parameters, such as the coefficient of performance (COP), the rate of refrigeration, and the power input. By using these expressions, the performance of the two-stage thermoelectric refrigeration system is discussed in detail. The maximum COP and rate of refrigeration are calculated, the internal structure parameter of the thermoelectric device is optimized, and the reasonable ranges of some parameters are determined. The results obtained here are compared with those of a single-stage thermoelectric refrigeration system, and consequently the advantages of two-stage thermoelectric refrigerators are expounded.     

A review on adsorption refrigeration technology and adsorption deterioration in physical adsorption systems

As one kind of environmentally friendly refrigeration, the adsorption refrigeration has attracted many attentions in resent decades. This paper introduces the researches of adsorption refrigeration systems with the commonly used working pairs, advanced adsorption cycles, heat and mass transfer enhancement and attempts of adsorption refrigeration applications. Poor heat and mass transfer problem is a bottleneck to prevent the improvements of the adsorption refrigeration technique. Two ways to enhance the heat and mass transfer are discussed in this paper. The adsorption deterioration of adsorbent, another obstacle to physical adsorption refrigeration applications, is also pointed out. And the possible reasons and the possible methods are analyzed.     

Vapour-compression refrigeration systems

Vapour-compression units are the most widely used refrigeration systems. Interactive computer routines have been composed, in BASIC language, in order to permit the prediction of the performances of simple, multi-evaporator multi-stage compressor vapour-compression refrigerators when employing refrigerant R-11, R-12, R-22 or R-502. Listings of the composed programs and samples of the predictions obtained are presented. Use of the programs should facilitate investigating the behaviour of refrigeration units, and in particular the selection of the most appropriate operating conditions and the identification of the optimal design specifications for a unit for a particular application.     

A semi-empirical model for steady-state simulation of household refrigerators

A semi-empirical modeling approach for simulating the steady-state behavior of vapor-compression refrigeration systems is presented in this study. The model consists of first-principles algebraic equations adjusted with experimental data obtained from the refrigeration system under analysis. Measurements of the relevant variables were taken at several positions along the refrigeration loop, supplying data for the calibration of the computer model. The predicted values of refrigeration capacity and power consumption when compared with experimental data were within ±10% error bands. The model was also employed to assess the effect of various system parameters on the refrigerator performance. Although a top-mount frost-free refrigerator was chosen for this study, the modeling methodology can be easily extended to other types of refrigeration systems, from domestic refrigerators to heat pumps.
