Description

Multifunctional refrigerating chamber management platform and method

Technical Field

The invention relates to the field of refrigeration equipment, in particular to a multifunctional refrigerating chamber management platform and a method.

Background

Refrigerators are of many types and are generally classified by their internal cooling, use, climatic environment, appearance, and cooling means.

Cold air forced circulation: also known as indirect cooling (air-cooled) or frost-free refrigerators. A small fan is arranged in the refrigerator to force air in the refrigerator to flow, so that the temperature in the refrigerator is uniform, the cooling speed is high, and the use is convenient. But because of the defrosting system, the power consumption is slightly larger and the manufacture is relatively complex.

Cold air natural convection type: also known as direct cooling or frosted refrigerator. The freezing chamber is directly surrounded by the evaporator, or the freezing chamber is internally provided with an evaporator, and the upper part of the cold storage chamber is provided with an evaporator which directly absorbs heat to cool. The refrigerator has a relatively simple structure and low power consumption, but has poor temperature ineffectiveness and is relatively inconvenient to use.

The cold air forced circulation and natural convection are combined: the new products of the refrigerator in the form are adopted more, and the advantages of wind and direct cooling refrigerators are mainly taken into consideration.

Detailed Description

Embodiments of the multi-purpose freezer management platform and method of the present invention will now be described in detail with reference to the accompanying drawings.

The refrigerator is a refrigerating device which keeps constant low temperature, and is also a civil product which keeps food or other articles in a constant low temperature cold state. The cabinet or the box is provided with a compressor, an ice maker for freezing and a storage box with a refrigerating device.

The volume of the household refrigerator is usually 20-500 liters. The first compression-type refrigerator for domestic use was introduced in the united states in the world in 1910. In 1925 sweden rody corporation developed a domestic absorption refrigerator. In 1927, the american general electric company developed a totally enclosed refrigerator. In 1930, air-cooled continuous diffusion absorption refrigerators adopting different heating modes were put on the market. A novel refrigerant Freon 12 is developed successfully in 1931. Domestic thermoelectric refrigerators began to be produced in the latter half of the 50 s, and refrigerators were produced in china from the 50 s. The freezing chamber is a place where the refrigerator freezes food.

In the prior art, the freezing chamber of various refrigeration equipment including a refrigerator inevitably brings frost due to the existence of internal food when refrigerating, so that defrosting is a necessary process. However, in actual operation, the defrosting mode of the freezing chamber is too solidified, and a corresponding defrosting strategy and a door control strategy cannot be formulated according to the area proportion occupied by food materials in the freezing chamber, so that the defrosting effect of the freezing chamber is poor or defrosting is excessive.

In order to overcome the defects, the invention builds a multifunctional refrigerating chamber management platform and a method, and can effectively solve the corresponding technical problems.

A multi-functional freezer management platform according to an embodiment of the present invention includes:

Next, a further description of the specific structure of the multi-purpose freezer management platform of the present invention will be continued.

In addition, DDR3 video memory can be regarded as an improved version of DDR2, which has many similarities, and mainly adopts an FBGA packaging mode of 144Pin ball-type pins. However, the DDR3 core is improved: the DDR3 video memory adopts 0.11 micron production technology, and the power consumption is obviously reduced compared with the DDR 2. In addition, the DDR3 video memory adopts the "Pseudo Open Drain" interface technology, and as long as the voltage is appropriate, the display chip can directly support the DDR3 video memory. Of course, the longer latency (CAS latency) of video memory particles has been a common problem of high frequency video memory, and DDR3 is no exception, with DDR3 having CAS latency of 5/6/7/8 compared to DDR2 of 3/4/5. Surprisingly, DDR3 has no dramatic technical advance over DDR2, but the performance advantage of DDR3 is still significant: (1) the power consumption and the heat generation are small: the training of DDR2 is absorbed, energy consumption and heat productivity are reduced on the basis of controlling cost, and DDR3 is more easily accepted by users and manufacturers. (2) The working frequency is higher: due to the fact that energy consumption is reduced, DDR3 can achieve higher working frequency, the defect of long delay time is made up to a certain degree, and meanwhile, the DDR3 can serve as one of selling points of the video card, which is already shown on the video card matched with the DDR3 video memory. (3) The overall cost of the display card is reduced: the DDR2 video memory granule specification is mostly 4M X32bit, and the 128MB video memory commonly used with middle and high-end video cards needs 8. The DDR3 video memory specification is mostly 8M X32bit, the single particle capacity is large, and the 128MB video memory can be formed by 4 particles. Therefore, the area of the display card PCB can be reduced, the cost can be effectively controlled, and in addition, the display memory power consumption can be further reduced after the particle number is reduced. (4) The universality is good: DDR3 has better compatibility with DDR2 than DDR is changed to DDR 2. Because the key characteristics such as pins, packaging and the like are not changed, the DDR3 video memory can be adopted by slightly modifying the display core matched with the DDR2 and the video card designed by a public edition, and the cost is greatly reduced for manufacturers. At present, DDR3 is widely applied to most middle and high-end display cards which are newly existed.
