Description

1300119 IX. Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a device for preventing dew prevention. The present invention relates to a control knot that automatically adjusts the apparatus for controlling condensation prevention in response to environmental climate changes. [Prior Art] The temperature inside the refrigerator and the refrigerated display cabinet is less than 5. Hey, cold-corrected products are even lower than - hunger, so the ship insulation layer is designed to avoid the intrusion of external heat sources, so that the outer wall temperature is higher than the dew point temperature (Dew pQint Tempem_, avoid condensation or frosting). The change of climate, the thickness of the insulation layer, the material of the insulation material, and the specific materials will make these cold; the insulation products of the East Refrigeration, in some cases (4), condensation on the surface of the product, such as The household electric picks have condensation problems in the rainy season gW. The refrigerated lion door panels are designed for the convenience of merchandise display, and are always designed in the form of glass windows. Therefore, if there is no prevention of condensation (defogation), I, and clothing 1 will not only appear in the product display. The problem is that the dripping water causes the display area to be messy, and it will cause additional damage to the electric energy. In the climate where the continental climate is very humid throughout the year (4), the wall of the household refrigerator usually does not need to increase the condensation prevention, but in the sub-fresh or coastal areas, About 1/6 of the season, the humidity will be high. If the refrigerator lacks condensation prevention device, there will be water droplets on the outer wall of the refrigerator, mold and power consumption. Plus the phenomenon of condensation household refrigerators wall

There are two kinds of prevention mechanisms: 1300119 adopts the design as shown in the first figure. The first figure is a schematic diagram of the structure of the outer panel of the refrigerator, including a casing sheet metal 10, an inner wall 12, a condensation tube 14 and a heat insulating material. 16, wherein the outer sheet metal 10 is made of stainless steel, the thickness is generally about 〇. lmm 'cold reduction official 14 is usually a copper tube, diameter of about 4mm, insulation material 16? 11 material, thickness about 60 legs, the condensation tube 14 of the refrigerating circulation pipeline is led to the inner side wall surface of the refrigerator outer panel, directly adhered to the outer sheet metal 10, using a large area of the refrigerator shell to dissipate heat, while maintaining the outer wall degree to the ambient temperature Compared with the forced convection design of the fan, this method has lower cost and noise, and looks good and does not sweat. It is commonly known as refrigerator, but its power consumption is about 15% higher than the convection design of the condenser. Currently, Taiwan and the Asia-Pacific region are large. Part of this design. The other design of the refrigerator suspension condensation prevention is similar to that of the cold; the east refrigerating display is similar to the glass door panel, and the electric heating wire is directly attached to the inner side of the outer sheet metal, and the 外/OFF switching is performed in synchronization with the compressor to maintain the outer wall temperature. Above ambient temperature. The condensation prevention method of the glass door of the cold bead refrigerated display cabinet is the same as that of the rear window defogging device of the automobile, and the electric heating wire is adhered to the glass, generally by a manual switch, so that the user can selectively close, if the defogging wire is activated, the glass door The surface temperature is often higher than that of human Wei Wen, the unnecessary power consumption of the job, if the miscellaneous 关闭 皿 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚 甚Produced so that the source of the display _ is not 1300119

Breaking the loss, the energy waste caused is even more serious. In summary, regardless of the use of the condenser to dissipate heat, adjust the refrigerator, the wall i degree, resulting in i, the use of waste 'this invention is aimed at this - the problem of changing the temperature of the outer wall of the refrigerator to adjust the condensation prevention (10) Li [invention content] Rong in the above-mentioned ♦ Ming Xiao Jing towel, the traditional use of condensation tube heat or electric heating line heating method will cause the refrigerator to test __. The purpose of this turn is to provide a kind of energy-saving removal. Its lions contain a control strategy in the defogging device, which can be used to make the most touching of the electric domain gods (4). (4) It will not cause additional waste of energy when the refrigerator is used. The other purpose of the 2nd is to provide the monitoring signal to the control strategy when using the sensor to measure the humidity change of the external temperature of the refrigerator. To adjust the heating power of the electric heating device 'to reduce the reduction can be more waste. ',,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Since the previous climatological data in the climate database is used for the marginalization: == the reference temperature of the lie (4), the two (4) are used to control the 1 X to reduce the heating power of the different heating power to reach the energy source.

And the display cabinet surface = the temperature difference value, provide - control strategy based on the temperature difference value to send a = gift - plus placement, shoot plus record - the power of the paste by the signal [implementation] this month - Some examples will be described in detail below. However, in addition to the detailed description, the present invention is also inconsistent in other real bribes. That is, the scope of the present invention is not subject to the claimed _, and the scope of the patent application for which the treasury is issued is subject to the patent application. Moreover, in the book towel, the components are not classified according to the size. Certain scales have been exaggerated or simplified compared to other related scales to provide a clearer description and an understanding of the present invention. 1300119 2 implementation of the financial 'exposure - a method to prevent replenishment and display cabinet condensation, cubic pure _ - ice surface report surface temperature, two under the _ conditions, calculate climatic conditions and refrigerator and display pivot surface temperature and temperature The value of the return, the control and the weaving are difficult to send according to the temperature difference - the signal is activated to start the heating device, wherein the ageing is set to - the power is controlled by the signal.

Further, the main feature of the present invention is that it can be designed to be designed due to the setting of the reference temperature difference ATb 25. Further, a heating power adjustment rate of the control reference temperature difference ATb 25 is changed, and the heating power adjustment rate can be expressed by the formula of ΔΤ-ΔΤΙο | MTb, for example, when the reference temperature of the control is set to g^Tb = 4t: When the temperature of the outer wall temperature and the dew point temperature reference value is recorded as ΔΤ = 21, the heating power adjustment rate of the actual device is only 50°/. However, the heating power of the conventional method is 1%, which saves nearly double the use of electric power, and does not allow the outside wall temperature of the new product to be higher than the set control ΔΤΙ). Since the heating power rate of this control method is adjusted at any time with the change of the temperature difference between the outer wall temperature and the dew point temperature reference value, and has the function of automatically responding to the environmental climate change, it will turn the wire mist ^ For example, if the condenser tube or the hand-held switch is heated, it can achieve energy saving.
