Analysis of the total heat exchanger types, characteristics and application status. Of the plate-fin heat exchanger research progress, introduced OxyCell working process and heat exchanger characteristics.
1, wheel-type heat exchanger
Rotary heat exchanger technology is more mature, efficient, self-purification, for a wide range of advantages. But its large size, location fixed, the resistance is large, there is cross-contamination [2]. The heat exchanger wheel moving parts need to consume their own energy and structure of some inherent flaws, air leakage and pollution of the core problem is still unresolved, thus affecting its overall performance.
2, plate-fin heat exchanger
Plate-fin heat exchangers due to no moving parts, there is no pollution of air leaks and core issues, has become a research focus in Western industrial countries. Plate-fin heat exchanger structure shown in Figure 1. Partition for the hydrophilic material with good heat transfer and moisture permeability, and airtight. When the diaphragm on both sides of the temperature difference between air and water vapor partial pressure, the air flow between both sides of heat and mass transfer. Plate-fin heat exchanger with high efficiency, compact, lightweight and strong, adaptable, and good economic benefits. But its resistance to a larger structure of gasket to be further improved.
Energy-saving air-conditioning system is imperative to reduce the energy consumption for air conditioning systems to reduce energy consumption, alleviate the current power shortage, optimizing energy structure and the protection of the environment and so has very important significance. Among them, the use of the whole air conditioning system heat exchanger is an effective energy saving measures. In this paper, the application of total heat exchanger Current status and progress analysis.
