How to do the promotion of refrigerator controller, how to adjust the refrigerator controller?

You should be talking about the refrigerator bosom friend, that is, the external time controller, which adjusts the start and stop time of the compressor to make the refrigerator refrigerated normally.

The start-up and shutdown time of the compressor is adjusted according to the ambient temperature of the season, and the specific ratio is: 1:1 to 1:1 in summer

between 2; It is generally around 1:3 in spring and autumn, and 1:5 to 1:1 in winter

10.It depends on the temperature in your room.

For example, in summer, the compressor should be set and adjusted for 20 minutes, and the compressor should be adjusted for about 20-30 minutes between shutdowns, and the compressor working time in spring and autumn should be about 10 minutes, and the shutdown time should be between 30-40 minutes; In winter, the compressor works for about 6 minutes, and the downtime is between 60-120 minutes.

It is recommended that you put a thermometer in the refrigerator to actually measure the temperature in the refrigerator, under normal circumstances, the refrigerator should be kept between 0-12 degrees, preferably between 4-8 degrees, and the temperature of the freezer should be about minus 18 degrees. If the temperature is low, make the working time shorter or the downtime longer; If the temperature is too high, just adjust the working time or downtime to a shorter time, and keep the temperature in the refrigerator within the normal range.

In addition, before use, the thermostat in the refrigerator should be adjusted to the highest setting, first turn on the power supply to let the compressor work for a period of time, wait for the temperature in the refrigerator to drop to the normal temperature range, and then cut off the power supply and connect the refrigerator bosom friend to use.

How to set the controller outside the freezer to refrigeration mode.

The controller is not only the development of the control board, but also the setting of the controller function, the development of the envy board is only achieved by embedding the program, and the function is embodied in the real smart refrigerator. At present, the development of smart refrigerator controller can refer to the smart refrigerator controller scheme of UU Zhongchuang, and its basic content is as follows:

1. With touch film function, rich in intuitive display interface, including LED and digital tube.

2. The compressor of the refrigerator is controlled by the relay, and the light and fan in the refrigerator are used to accurately control the moisture partition of the dry brother, perceive the freshness status in real time, and intelligently match the storage environment of different ingredients.

If it's two lines, you don't have to recognize it. That's the case with my refrigerator mechanical thermostat. It's like you don't have to recognize the socket. Maybe that's what mechanical temperature control is. I don't know about the rest.

Refrigerator thermostat replacement and identification.

The wiring error of the new thermostat is also common in refrigerator maintenance, especially if there are 3 terminals, it is easier to connect the wrong wire. When replacing the thermostat with 3 terminal rods, it should be noted that the wiring color is consistent with the letters "H, L, C" or the number marked next to the thermostat, and the wrong connection should not be made, otherwise the thermostat will fail.

H and L, or 6 and 3 are manual disconnect functions, L and C or 3 and 4 are turned on when the temperature rises and disconnected when they fall.

That is: H - for the power inlet and bulb - 6L - connected to the electric heater - 3C --- connected to the compressor and winter switch - 4

At present, Haier brand refrigerators have become famous brand products, which have come all the way after decades of wind and frost, and Haier is also a leader in first-line brands.

In the early days, it mainly relied on product quality, technology and advertising services to penetrate into the common people and establish famous brands.

In addition to these, Haier also pays special attention to after-sales service, no matter what the problem of the product is, in solving the problem, so that consumers can rest assured, which is also the outstanding feature of the Haier brand.

Now there are Haier in all major appliance stores, and the sales volume and market share of its refrigerators are also high.

In short, business is calling for integrity, and gaining the trust of the people is not something that can be done overnight, sometimes doing business is the same as the principle of being a man at the macro level, and those who win the hearts of the people win the world.

This brand is the first in the world, how can it still be promoted, and someone will buy it if you go, mainly you go to the big supermarket and electrical appliances.

The promotion you ask is what you want to do now. Or how did Haier refrigerator do it to the current scale?

It is to analyze Haier's marketing model and make a case .

Or do you work in outreach and want to ask what exactly should be done?

What is your positioning, please. Is it to analyze the case or to work in this position?

The refrigerator temperature control knob is generally geared, and the higher the number, the lower the temperature in the freezer. Generally, we put it on 3 gears in spring and autumn, depending on your requirements, whether the freezer can reach below minus 18 degrees. In order to achieve the purpose of food preservation and power saving, we can hit 1 or 2 gear in summer, and 4 or 5 gear in winter.

Some people may want to ask, in winter, the temperature is low, but the temperature is set low (the thermostat value is large), and in the summer, the temperature is high, but the temperature is set high (the thermostat value is small), is it the opposite? In fact, many people have this misconception, thinking that the temperature of the refrigerator can be set high when the temperature is low in winter, and the temperature should be set low when the temperature is high in summer.

Because, the temperature of the freezer compartment of the refrigerator is controlled by the temperature in the storage room, and look at your temperature control knob is in the storage room. The temperature in the storage room is generally 4 8 degrees, in winter, the indoor temperature is close to this temperature, if the thermostat knob is still on 3 or less than 3, the refrigerator compressor is rarely started, although the temperature in the storage room can meet the requirements, but the temperature of the freezer can not reach below minus 18 degrees, the food is easy to deteriorate, and the food thaws and melts in serious cases. In summer, the temperature is relatively high, if the thermostat knob is still on 3 or greater than 3, the refrigerator storage room in order to meet the temperature requirements, the compressor starts frequently, although the temperature of the freezer is lower than minus 18 degrees, but it causes a waste of electrical energy, shortens the service life of the refrigerator, which is also undesirable.

So properly adjusting the refrigerator temperature controller knob can keep us fresh and save electricity.

Adjustment method: The temperature control knob is generally appropriate, the higher the number, the lower the temperature in the freezer.

1.In summer, when the ambient temperature is high, the temperature should be adjusted between 1-2 gears. In winter, play 4th or 5th gear.

2.Now there are also smarter refrigerators, the temperature of the refrigerator is displayed digitally, and we can adjust it by touch.

3.Most refrigerators have the opposite number of refrigerator room thermostats that represent the temperature. That is, the lower the temperature, the higher the number.

Working principleThe action of the vapor pressure bellows acts on the spring, the elastic force of the spring is controlled by the knob on the control board, and the capillary is placed in the refrigerator refrigerator to react to the temperature of the indoor circulating return air. When the temperature rises to the set temperature, the thermostat gas in the capillary tube and the bellows expands, so that the bellows elongates and overcomes the elastic force of the spring to connect the switch contacts, at this time the compressor runs, the system is refrigerated, until it drops to the set temperature, the temperature sensor gas shrinks, the bellows shrinks and the spring acts together, the switch is placed in the disconnected position, and the motor circuit of the compressor is cut off. In this way, the action is repeated to achieve the purpose of temperature control.

Electronic temperature controller.

The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, generally using platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, and these resistors have their own advantages and accuracy. Most of the sensors in household air conditioners are thermistors.

Thermistor thermostats are made according to the Wheatstone Bridge principle, Wheatstone Bridge. Therefore, when composing a thermostat, the temperature regulation range and operating temperature can be easily changed by selecting the appropriate thermistor.

What is the inner workings of the refrigerator thermostat? Take it apart to see which parts are composed, no wonder it causes icing and not cooling.

Turn on and work every few minutes, and turn off for a few minutes.
