The Development And Performance Analysis Of Thermoelectric Heat Pump Heater

Thermoelectric effects , discovered in the mid-upper term of the 19th century ,had been less applied in practical projects during more than 100 years after its discovery because of its inefficiency , but the discovery of materials with high thermoelectric properties made thermoelectric effects be applied in practical projects in 1950's , which involved many fields , such as national defense , industry agriculture , medicine , commerce , daily lives and so on .On the analysis of fundamental principle of thermoelectric refrigeration , at first , there present five thermoelectric effects which are Peltier effect , Seebeck effect , Joule effect and so on . and there present the mechanism of the thermoelectric refrigeration , the analysis of the best character about thermoelectric refrigeration , the design of the thermoelectric refrigeration and all kind of exchange mode of the cold surface and the heat surface .Peltier heat is foundation of thermoelectric refrigeration circulation . temperature distributing inside p type and n type and diathermanous mechanism are different .temperature field of the cold surface and heat surface is asymmetric .Developing a thermoelectric heat pump heater, all kind of index answer for national standard . testing data make clear that its heating performance factor reached 1.3 or so. Compared with conventional electricity heater, its can save energy by 30% or so. And analysis its diathermanous performance.On the basis of the feasibility analysis of building energy consumption and the feasibility of waste heat recovering ,taking middle or high-grade hotels for example , the methods exploration of waste heat recovering have been conducted by the means of thermoelectric heat pump apparatus ,and it is showed that the latent capacity of energy conservation is very large if we can utilize thermoelectric heat pump apparatus to recovery the waste "hot" of or "cold" energy in air displacing or to heat water of refrigerant compressor unit and waste energy in daily waste water, which , at the same time ,achieve the double goal of energy saving and environment protection by means of removing the "heat" pollution in environment.
