“…(Domanski, 1991) proposed a tube-by-tube computation approach which he applied to study the effect of non-uniform air distribution on the performance of a plate-and-tube heat exchanger. Based on the same approach, (Bensafi et al, 1997) design and simulation of finned-tube heat exchangers for a limited number of pure and mixed refrigerants in evaporation or condensation. This model can handle circuiting but requires user intervention to fix mass flows in each circuit.…”

Simulation technology has been widely used for performance prediction and optimal design of refrigeration and air conditioning appliances. A brief history of simulation technology for refrigeration and air conditioning appliances is reviewed. The models for evaporator, condenser, compressor, capillary tube and thermal insulation layer are summarized, and a fast calculation method for thermodynamic properties of refrigerant is introduced in this paper. The model-based intelligent simulation technology and the simulation technology based on graph theory are also illustrated. Finally, an updated trend of simulation technology development for refrigeration and air conditioning appliances is discussed.The output of refrigeration and air-condition appliances have been increasing rapidly in recent years, especially in China. For example, the annual output of room air conditioners in China is over two thirds of the world total, and the use of air conditioners consumes a lot of electricity, amounting up to 40% of the total electricity consumption in the summer in some cities like Shanghai. Therefore it is an important target to make the design process of refrigeration appliances more efficiently and to improve the product performance. Computer simulation technique is one of valuable means to accomplish this target [1][2][3] .The traditional methods for designing refrigeration and air-conditioning appliances are: to determine the required performance object of a product at first, then to estimate the working conditions, and to calculate the structural parameters at last. This process is very straightforward and quite easy to be understood. But the actual performance of the product might obviously deviate from the required one because there is no accurate model available in the design process. In order to let the products have the desired performance, the processes of developing prototypes, testing their performance and modifying their structures have to be repeated many times, which will increase the cost and delay the completion of the design process.With the computer simulation method, the working conditions and the structural parameters of the product are given, and then the performance is predicted. After predicting the product performance by simulation, the configuration parameters of the product can be evaluated easily. In order to get a group of suitable configuration parameters of the product, the original parameters should be adjusted according to the simulated results, and simulation with the adjusted structural parameters will be done again. The process of modifying the parameters and simulating with modified parameters will be repeated many times until a set of the most suitable parameters is obtained. Such a computation process is an optimization process, which can be implemented by adding some optimization programs or directly operated by users based on their experience. In order to obtain a perfect optimization result quickly, the initial parameters should not be far away from the optimal ones. It is recomme...

“…Domanski (1991) suggested a model based on dividing coil in successive finite volumes following the tube fluid path. Bensafi et al (1997) proposed a similar model, but used local heat transfer coefficients instead of average ones extensive to the overall heat exchanger area. Vardham and Dhar (1997) proposed a model that, similarly to the previous ones, divides the coil into finite volumes along the tube fluid path and carries out iterative marches between the tube fluid entrance and exit, while simultaneously updating the air-side properties.…”
