Humidity adjusting method and device for semiconductor refrigeration box

Abstract

A humidity adjusting device for a semiconductor refrigeration box comprises a TEC (Thermoelectric Cooler) (1) mounted on the refrigeration box (10). One side of the TEC (1) is connected with a cool-end heat exchanger (2) arranged in a box body of the refrigeration box (10), and the other side of the TEC (1) is connected with a hot-end heat exchanger (3) arranged outside the box body. An inner circulation fan (4) is arranged on the cool-end heat exchanger (2); an in-box temperature sensor, an in-box humidity sensor, and a controller capable of conditioning working voltages of the TEC (1) and the inner circulation fan (4) are further arranged in the box body; and the in-box temperature sensor and the in-box humidity sensor are both connected with the controller. The device can realize a constant-temperature dehumidifying function by using former refrigeration equipment of the refrigeration box (10), and additionally arranging the controller for conditioning the working voltage of the inner circulation fan (4). Further provided is a humidity adjusting method for the semiconductor refrigeration box, which stores cooling capacity in the cool-end heat exchanger (2) by rapidly refrigerating and turning off the inner circulation fan at a cool end simultaneously, and realizes the constant-temperature dehumidifying function by rapidly increasing the working voltage of the inner circulation fan (4) and carrying out rapid humidity adjustment. The control method has no cooling capacity loss, can individually adjust the humidity, and can monitor a relative humidity value in the refrigeration box in real time. The device is simple in structure and low in manufacturing cost.

Description

【Technical field】 [0001] The invention relates to a dehumidification device, in particular to a method for adjusting the humidity of a semiconductor refrigeration box and a device thereof. 【Background technique】 [0002] With the development of science and technology, many wine cabinets for storing red wine use semiconductor wine cabinets. This kind of wine cabinet is a refrigeration box that uses TEC (Thermoelectric Cooler, semiconductor refrigerator) refrigeration technology. The inside of the box needs to maintain a certain temperature. and humidity, the general technology is only to control the temperature in the refrigeration box, and use the drying effect brought by the refrigeration to make the box meet a certain humidity requirement, but in this case where only the temperature is controlled, the humidity in the box cannot be controlled, and it is often difficult To meet the desired humidity requirements, long-term use of refrigeration boxes often encounter moisture i...

[0002] With the development of science and technology, many wine cabinets for storing red wine use semiconductor wine cabinets. This kind of wine cabinet is a refrigeration box that adopts TEC (Thermoelectric Cooler, semiconductor refrigerator) refrigeration technology. The inside of the box needs to maintain a certain temperature. and humidity, the general technology is only to control the temperature in the refrigeration box, and use the drying effect brought by the refrigeration to make the box meet a certain humidity requirement, but this kind of situation where only the temperature is controlled, the humidity in the box is uncontrollable, and it is often difficult To meet the desired humidity requirements, long-term use of refrigeration boxes often encounter moisture infiltration, or due to temperature changes and a certain amount of moisture brought in when the door is opened, the moisture in the box rises, and the inner wall of the box, box There may be condensation on the surface of the items in the box, which will cause deterioration and damage to the items in the box. For example, the taste of red wine will not be able to guarantee the quality. If the red wine is stored in it for a long time, it will cause mold on the red wine label due to humidity. , Black, or even moldy and fall off, and finally cause the red wine label of the whole wine cabinet to rot, the taste of the wine becomes sour, the red wine loses its original value, and thousands or even tens of thousands of bottles of red wine are also destroyed, which is a pity
