Comparison of semiconductor refrigeration technology and compressor refrigeration technology

Comparison of semiconductor refrigeration technology and compressor refrigeration technology The mechanical compression refrigeration system includes a compressor, a condenser, a filter, a solenoid valve, an expansion valve, an evaporator, a liquid reservoir, a refrigerant, etc., and connects various components through pipes. Compressor cooling disadvantages: It is difficult to start at low temperature, low heating efficiency in winter, fear of vibration, can not tilt, let alone reverse. System maintenance requires fire work to replace damaged components. In case of damaged components and pipelines, it is necessary to let go of the refrigerant in order to fire the industry, and there is a certain amount of waste. Compressor refrigeration advantages: The refrigeration efficiency is high, and the COP can reach 3.8., Energy saving and environmental protection. Semiconductor air conditioners are composed of semiconductor cooling fins, cooling fins, heat sinks, etc., connected by cables. Disadvantages of semiconductor refrigeration: The cooling efficiency is low, up to 0.6. The cooling performance varies nonlinearly with the influence of ambient temperature, voltage, thickness of the cooling block, cooling mode of the cold end, mechanical pressure, and material of the thermally conductive phase change material. Advantages of semiconductor refrigeration: The semiconductor air conditioner has no refrigerant, will not leak, is not afraid of vibration, not inclined, and not reversed; there is no mechanical movement during operation, it will not be worn; small size and high reliability. The specific advantages are reflected in the following points: 1. First of all, the thermal inertia of the semiconductor cooling chip is small, and the cooling and heating can be switched at will. Cooling and heating time is very fast, usually the maximum temperature difference can be reached within a few seconds 2. The semiconductor air conditioner has a wide range of cold and hot adjustments, and fast conversion between cold and heat. Large temperature difference environment, even if the external environment is up to 60 degrees, the surface of the cooler can still maintain 22 ~ 25 degrees 3. The semiconductor air conditioner is a transducing element, and the temperature of the cabinet can be accurately controlled by controlling the current and voltage. At the same time, semiconductor air conditioners are used in multiple groups in parallel, even if one group fails, it will not affect the cooling effect. 4. The heating surface temperature of the semiconductor air conditioner is lower than 80 degrees, there is no open flame, and it is safe and reliable for the equipment
