Seven characteristics of wine storage in Yabang wine cabinet:

(1) Constant temperature: The constant temperature of the wine cabinet is strictly controlled by each wine cabinet, so it is called a constant temperature wine cabinet, so one of the main differences between it and the traditional refrigerator freezer is to control the temperature. The temperature of the strict Yabang wine cabinet should be kept constant for a long time. Even if the door is opened and closed frequently, the temperature should reach the temperature set by the owner in a short time and work continuously near this temperature. In addition, her anti-environmental temperature has reached more than 40 degrees.

(2) Constant humidity: Humidity is the second biggest problem of wine cabinets, which is mainly affected by temperature and wind circulation. The stability of temperature has great influence on the stability of humidity. If the temperature changes greatly, the humidity will not be constant. If it is traditional direct cooling refrigeration, the wind circulation is not obvious, which will cause uneven temperature and humidity in the cabinet, resulting in a large amount of water in the cabinet and even wetting the wine label. The humidity control range of Yabang wine cabinet is H (65-80), which meets all your requirements for wine storage.

(3) Shock absorption: Yabang adopts German compressor manufacturing technology to solve the vibration and sound problems of constant temperature wine cabinets.

(4) Avoid light: strong light will also affect the continuous growth of red wine in the bottle, so it is necessary to limit the light transmittance of the wine cabinet door. Yabang wine cabinet can effectively avoid strong light, block ultraviolet rays and care for your wine.

(5) Ventilation: Yabang wine cabinet adopts air circulation refrigeration, and the upper and lower air circulation systems in the cabinet ensure uniform temperature and humidity in the cabinet.

(6) Deodorization: If the wine cabinet has an odor, it will also affect the red wine. Uniform air circulation refrigeration can continuously discharge fresh air, extract air from the cabinet, ensure uniform temperature and humidity in the cabinet, and solve air quality problems.

(7) Wine rack: Yabang wine cabinet adopts a relatively safe and convenient roller wine rack, so you don't have to worry that if you accidentally pull out all the wine racks, the red wine will fall to the ground, and the wine label of the upper wine will be accidentally damaged when you take the wine rack. The wine rack can be disassembled and installed at will to meet your different needs.

Brief introduction of semiconductor refrigeration technology

Thermoelectric refrigerator, the core component of semiconductor electronic refrigeration, is the application of the above principle, which is composed of different semiconductor P-type and N-type materials connected by a certain connection method. When DC current passes through, one end emits heat and the other end absorbs heat. Once the heat generated at the exothermic end is dissipated, the temperature at the endothermic end will be greatly reduced, thus realizing low-temperature refrigeration. In practical application, alternating current is converted into direct current through transformer, and the current forms two ends of heat absorption and heat dissipation through semiconductor material, and the heat dissipation end dissipates heat through aluminum sheet and fan. This cycle is the working process of semiconductor refrigerator and wine cabinet.

The traditional refrigerator refrigeration technology uses freon or other compound preparations to realize refrigeration. The leakage of freon or other compound preparations will cause certain pollution to the surrounding environment. More importantly, these refrigerants have a strong destructive effect on the atmospheric ozone layer and have been eliminated one after another. Modern high-tech semiconductor refrigeration technology does not need any refrigerant, but can realize refrigeration by using the Peltier effect of semiconductor. Today, when we are committed to protecting the global environment, developing a refrigeration technology with superior performance and no harm to the environment has become an important topic in the field of global refrigeration technology research. Therefore, semiconductor refrigeration technology has broad development prospects. The thermoelectric effects of conductors mainly include Seebeck effect, Peltier effect, Thomson effect, Joule effect and Fourier effect. Semiconductor refrigeration technology uses peltier effect.

Peltier effect is the inverse effect of Seebeck effect, and the heat generated by Peltier effect is called Peltier heat, which is proportional to the current intensity of the loop, and its direction will change with the change of current direction, that is, the cold end and the hot end are exchanged. The mechanism is that charge carriers are at different energy levels in different materials. Under the action of external electric field, when charge carriers move from high-energy materials to low-energy materials, excess energy will be released. On the contrary, when charge carriers move from low-energy materials to high-energy materials, they need to absorb energy from the outside. Energy is released or absorbed in the form of heat at the interface of different materials. The peltier effect of metal materials is weak, while that of semiconductor materials is much stronger, so semiconductor refrigeration is used in practical engineering.

The peltier effect was discovered by J.C.A peltier in 1834. When electricity is applied at the junction of two different metals, depending on the polarity, the two metals will produce cold effect and thermal effect respectively. When the number of joints increases, the cold and hot effect also increases. The cooling effect can be improved to the greatest extent by using cooling aluminum sheet and cooling fan. Meguiar's Peltier Chip consists of 27 different pads on the surface and inside 127, the dimensions are 30*30mm and 40*40mm respectively, and the current specifications are 3 amps and 4 amps respectively.

Advantages of semiconductor refrigeration technology

(1), no moving parts, so no noise, no wear, long service life and high reliability when working.

(2) No refrigerant, no leakage and no environmental pollution.

(3) The parameters of semiconductor refrigerators are not affected by the spatial direction, that is, by the gravitational field, so they are widely used in the aerospace field.

(4) It has the advantages of fast action, reliable operation, long service life, easy control and convenient adjustment, and the refrigeration capacity can be adjusted by adjusting the working current. The working state of cooling or heating can also be changed by switching the direction of current.

(5) Small size and light weight, suitable for special refrigeration environment with small capacity and volume.

Although semiconductor refrigeration has many advantages, there are also some shortcomings to be overcome.

(1), the refrigeration efficiency of semiconductor refrigerator is lower than that of mechanical compression refrigerator under the condition of large refrigeration capacity. Therefore, semiconductor refrigerators can only be used as low-power refrigerators.

(2) The power supply in thermocouple calibration can only use DC power supply. If AC power supply is used, Joule heat will be generated, and the purpose of absorbing heat and cooling can not be achieved.

(3) The components of thermocouple stack are made of high-purity rare materials, and the process conditions are not very mature, which leads to the high cost of components and cannot be widely used in the general refrigeration field.
