How to adjust the temperature in the refrigerator showcase. Refrigerated showcase setting: temperature control

Refrigerated showcases, unlike classic refrigerators and chests, require temperature and operating mode settings. This is due to the fact that completely different products that require different temperatures can be stored in refrigerated display cases. To learn how to set up the refrigerated showcase, read the instruction manual.

For meat and fish, they usually set -2 degrees, for cakes and pastries +7, for vegetables and fruits +8 or more. Also, a lot depends on the humidity in the room and in the showcase itself. Properly adjusted and tuned, it allows the products not to lose their presentation for several days, does not weather them, and does not itself become covered with hoarfrost and condensate.

Remember that refrigerated display cases are designed for temporary storage of products. This means that the goods in it must be changed regularly, and the unsold goods must be sent to cabinets or chests for storage. Some devices, such as Cryspi freezers, allow you to lower the temperature to -8 degrees during non-working hours, which significantly extends the shelf life of goods. But more often than not, this feature is the exception rather than the rule.

How to set the temperature in the refrigerated display case

Refrigeration equipment is a complex system that should be set up and maintained by a professional. General information on setting the temperature mode is in the instruction manual. Be sure to read it before you get started. If something is not clear to you, then it is better to contact the master - this will help to avoid further costly repairs.

The temperature setting and programming of the showcase takes place through the control unit. Usually it is located at the bottom of the showcase on the seller's side. Most modern models are configured via the remote control - from it you can set the operating temperature and operating modes. Tuning through the block requires qualification. Determine what temperature should be in your showcase and set it from the remote control. The showcase has its own thermometer, which shows the current temperature - the software and physical ones must match.

Often there are cases when the actual and programmed temperatures differ from each other. This situation arises due to the contamination of the heat exchanger: it is covered with ice, dust, various debris and grease. It is necessary to monitor its cleanliness and at least once a month to do a “general cleaning” in the window. Ariada freezer cabinets have automatic system defrosting - they need to be connected to a special drainage for proper operation. Other showcases simply need to be unplugged and washed with warm water and soda.

How to set the temperature in a refrigerated display case

The initial temperature adjustment will be carried out by a specially trained person after the cabinet has been installed. Consult with him about this process - usually there is nothing complicated in it. Raising and lowering the temperature from the remote control is generally carried out using one button (like the volume on a TV). Setting the temperature through the block is more difficult, since any mistake can lead to zeroing the program. Also, the settings may be lost if the power is turned off at the moment when you change the program. In such cases, you will have to call a professional who will completely reprogram the device.

How to lower the temperature in a refrigerated display case

Sometimes situations arise when the temperature in the showcase does not drop to the required temperature. Why is this happening? There can be many reasons - a damaged compressor, low pressure or refrigerant leakage, overgrowth of the heat exchanger with ice or dirt, loosely closed shutters. If the temperature does not drop to the required level, then defrost the display case, wash the heat exchanger well, remove dust from the external compressor, and clean the grooves along which the curtains go. If this does not help, then reduce the temperature through the remote control by a few degrees and see if it drops in the showcase. If yes, then just leave it as it is. If not, call a specialist.

Instruction

Turn on the computer and hold down the Delete key (F2, F8). After a while, the BIOS menu of the motherboard will open. To change the temperature of most devices, you can change the fan settings. Press the key combination F1 and Ctrl, go to the Advanced Setup or Advanced Configurations menu.

Find the item responsible for the cooling parameters of the system. First, activate the Always On parameter, opposite the Fan Mode item. This feature prevents the fans from turning off. Find the Fan Speed item and set the required values \u200b\u200bfor each cooler. Please note that your version of the motherboard may not have this feature.

Press the F10 key and confirm the restart of the computer while saving the settings for the coolers. If, after following the procedures, the temperature of certain devices still exceeds the norm, then try to reduce their performance. Usually it concerns the central processor. This operation will lead to a decrease in the speed of the PC, so this method is resorted to only in extreme cases.

Install the Speed Fan program and try using it to change the fan settings. Activate the item "Auto adjustment". This will allow the utility to automatically increase the rotation speed of the desired coolers to increase the degree of cooling of devices.

If none of the above methods proved effective, then replace the desired fan. Choose a device with more power. Remember that the size of the cooler also matters. It is better to choose devices that allow you to configure them programmatically. Connect the selected fan to the desired device, turn on the computer and open the BIOS menu. Adjust the settings for the new cooler.

Installation new version The BIOS is capable of opening up new possibilities for overlocking and working with the contents of the computer. After the update, old errors in working with hardware are often corrected. The manufacturer often updates the BIOS version for their motherboards and offers users several ways to install - via DOS or directly from the system.

You will need

- Windows 98 or Windows ME boot floppy image;
- the flasher program and the BIOS firmware itself, downloaded from the website of the motherboard manufacturer

Instruction

Create boot disk, specifying the path to the boot floppy image file and adding the appropriate BIOS files to the disk. You can do this with Nero or Ultra ISO. The recording algorithm in these applications is similar. You need to open the system image file with the program and copy the files from the BIOS.

Reset the BIOS version. To do this, remove the battery from the motherboard for about 10 minutes, or select "Load Defaults BIOS" in the settings.

Insert the burned disc into the drive, restart the computer. The command line will launch. Type "dir" and the firmware and BIOS files will be shown. Copy the awdflash.exe and copy nf3916.bin files to the virtual disk using the copy commands ("copy awdflash.exe C:" and "copy nf3916.bin C:").

Go to the appropriate section with the "C:" command. Set the parameters "awdflash nf3916.bin oldbios.bin /py/sy/cc/cp/cd/e".

Copy the old version back to a floppy disk (copy oldbios.bin A: command) and reboot the computer using the Ctr, Alt and Del keyboard shortcuts. You can go into the BIOS and make the necessary settings.

note

All actions are performed at your own peril and risk. If the firmware is unsuccessful, the computer will not be able to boot and will have to be carried to service center. If it is not known exactly what benefits a BIOS update will provide, then it is better not to update it.

You should not update the BIOS directly from Windows, as this may cause the system to become completely inoperable. If you still want to "update" directly from the system, then do it in full accordance with the manufacturer's instructions. Also pay attention to the driver version, which must be at least version 6.66 (in the case of ASUS motherboards).

Go to the Boot sector. The BIOS commands are controlled using the cursor buttons and the Enter key. Find the Boot device parameter - it is responsible for the boot sequence from devices. Highlight the desired option with the arrow and activate it with the Enter key. Select to download first HDD, to do this, select First Boot Device and press Enter, select HDD, and press Enter again.

Go to the Power section to set the BIOS settings for the cooler and processor. Enable control of the system cooler as well as the CPU cooler. To do this, set the CPU Q-Fan Control option to Enabled, and set the CPU Fan-Profile option to Optimal.

Remove the boot logo when you turn on the computer to speed up system boot. To do this, go to the Boot sector, select the Boot Settings Cohfiguration option, find the Full Screen Logo item, set this parameter to Disabled.

Go to the Standard CMOS Setup section to set up the system date and time, as well as settings hard drives computer. In the Integrated Peripherals section, you can set interface settings, as well as additional system functions. To set power and power options, go to the Power Management Setup section. The function of binding to computer expansion cards can be set in the PnP/PCI Configurations section.

To determine the readings of system sensors (CPU temperature, fan speed), go to the Hardware Monitor section. To restore the default BIOS settings, go to Load Setup Defaults.

note

Commands in different BIOS versions may differ slightly from those described above.

You need to know the bios version, first of all, for reasons of its timely update, which will optimize the performance of your personal computer. There are several ways to set the bios version. Read about some of them below.

Instruction

Start your personal computer. You can determine the BIOS version by reading it in the top lines of the information that is displayed on the screen at startup. If you did not have time to orient yourself and read the desired text, restart your computer again. As you may have guessed, you can’t restart your computer indefinitely, so if you can’t read quickly, do the following.

Check the BIOS version on the motherboard of your personal computer. To do this, you will have to open the system unit. Take a screwdriver and remove the screws that secure the side panel. Take it off.

Take a close look at the motherboard. Find her name. Next to it, the BIOS version should be indicated. By and large, this is a primitive way. Better run the BIOS and see its version directly there. To do this, when the computer boots up, press the delete key. Then use the arrows to navigate to Main and then to System Information. There you will find comprehensive information regarding bios.

Go to the start button menu. Select "Run". At the command prompt, type msinfo32. Then press the enter key. The System Information tool will launch. In the corresponding section you can find all the information you need about the BIOS. Going to "System Information" can be easier. Go to the Start button menu, select "All Programs", then "Accessories" and "System Tools". In the latter, find the item "System Information".

Use the Everest Ultimate Edition program. She will provide you with similar information. Run the program, find the item "System board". Go into it. In the central window, you will find all bios data, including version, year of manufacture, and manufacturer information.

Refrigerator cycle

The operation cycle of the refrigerator is understood as the time from the moment the motor-compressor is turned on, the duration of its operation and the time at which the motor-compressor is in the off state. The time of one cycle, for most refrigerators, ranges from 8 to 15 minutes. The number of such cycles per hour, respectively, will be from 4 to 8. It should be noted that the duration of one cycle or the number of cycles per hour during the day will not be constant. That is, various factors affect the duration of the cycle and the number of cycles:

air temperature in the apartment,
the amount of use of the refrigerator and freezer,
lowering or raising the temperature in the heating batteries of the apartment,
shifted temperature control knob

Now, let's take a closer look at how to set the temperature in the freezer correctly.

How to set the temperature - in the freezer

The temperature in the freezer is set according to the storage period you have chosen for the frozen food. The so-called gradations for refrigerators have been established according to the temperature regime in the freezer.

If the shelf life of frozen foods is about three days, the temperature is set from minus 6 degrees and below. From minus 12 degrees and below, products should be stored for up to 3 weeks. From minus 18 degrees and below, the shelf life of products is up to 3 months.

Temperature in refrigerator compartment

The temperature for both the freezer and the refrigerator compartment (refrigerator) is set using the thermostat knob and it should be noted that the temperature in the refrigerator is set automatically, due to the set temperature in the freezer. Why is this happening - you ask? Yes, because the thermostat in the refrigerator does not respond to the temperature in the refrigerator compartment, but to the temperature in the freezer compartment, or rather, to the temperature of the evaporator wall, to which the thermostat bellows tube is attached. You should also know that the temperature in the refrigerator compartment, at the set temperature regime, can vary from 6 to 7 degrees, depending on the factors that were given above. The thermostat knob is set approximately in the middle position (on the scale).

So, for example, with the thermostat knob in the middle position and at an air temperature in the apartment of +25 degrees, the temperature in the refrigerator will be approximately +3.5 degrees, and in the freezer compartment (chamber) the temperature will be about minus 6.2 degrees. Such data, I have given from the technical literature (outlined material).

I would like to provide you with approximate temperature characteristics (for many types of refrigerators), that is, copy the graph on the Internet. Unfortunately, such data on the Internet is not accurate. Therefore, I will draw graphs of temperature changes in the refrigerator and freezer by hand (depending on the ambient temperature), and additionally add data to this topic.

How to check the temperature - in the refrigerator

The temperature is measured in the refrigerator under basic conditions:

1. The refrigerator must be empty, the ice molds must be removed,

2. Refrigerator accessories must be dry and thoroughly wiped,

3. When checking the temperature in cold rooms, the ambient temperature must be constant,

4. When measuring the temperature in the freezer, the thermometer should be placed in the center of the freezer shelf,

5. When measuring the temperature in the refrigerator compartment, the thermometer is installed on the middle shelf of the refrigerator compartment,

6. If the temperature is measured with mercury or alcohol thermometers, the possibility of an error in the direction of temperature increase (when opening the refrigerator) must be taken into account.

The temperature must be measured once every hour, with the refrigerator mode set. Then, you need to compare (compare) the difference in measurements for two hours. This difference should be no more than 0.5 degrees Celsius.

For meat and fish, they usually set -2 degrees, for cakes and pastries +7, for vegetables and fruits +8 or more. Also, a lot depends on the humidity in the room and in the showcase itself. A properly adjusted and adjusted refrigerated display case allows the products not to lose their marketable appearance for several days, does not weather them, and is not itself covered with hoarfrost and condensate.

How to set the temperature in the refrigerated display case

Often there are cases when the actual and programmed temperatures differ from each other. This situation arises due to the contamination of the heat exchanger: it is covered with ice, dust, various debris and grease.

How to lower the temperature in a refrigerated display case

http://ooopht.ru/211/1202/1098.html
At the factory, the electronic unit of the refrigerated display cases is set to the standard operating mode.

We adjust the electronic unit of the refrigerated display case in accordance with the climatic conditions and the goods stored in the display case. Gastronomy - sausage and cheeses. We will increase the duration and frequency of the defrost time.

This is necessary so that the evaporator is not clogged with a snow coat. We press and hold the SET button until CP lights up on it. We press the up arrow until dEF lights up. We once again press and hold the SET button until diE lights up. Press the SET button - a number will appear, by default 6. This is the defrost frequency in hours. Use the down arrow to change the defrost interval to 4 hours. Press the SET button. The indication diE appears. Use the down arrow to find the value of dEE. Press the SET button. The display shows the number 30, the defrost time in minutes is the factory default setting. Use the up arrow to increase this figure to 40. Press the SET button, and 2 times the fun button, - the settings are saved and changed.

As a rule, according to the recommendations of manufacturers, they are intended for operation in rooms with an ambient temperature ranging from +12 °С to +25 °С and relative humidity of not more than 60%.
The showcase must be installed in such a way that the impact of air currents (drafts) on it is prevented or their intensity is reduced to a minimum.

It is forbidden to install a refrigerated display case in the following places:
1. near doors and in drafts caused by opening doors or windows;
2. in areas where strong air movement is possible (for example, outlet ceiling lamps for climate, ventilation and heating systems);
3. in close proximity to sources of heat (such as radiators, heating or cooking equipment);
4. in direct sunlight.

Air flows with a speed of more than 0.2 m/s worsen the temperature performance of the refrigerated display case.
If the above installation rules are not strictly observed, the performance of the display case may deteriorate and power consumption may increase.

Temperature control

Temperature control in the useful volume of the refrigerated display case is carried out or
using a mechanical thermometer installed on the side of the air intake grille, or using an electronic controller located in the showcase control unit (since the controller displays the average temperature in the useful volume, the readings of the mechanical thermometer and the controller may differ by several degrees).

Note:
Responsibility for compliance with the current food storage standards lies with the display case user.
We remind you that the showcase is intended for storing pre-frozen food (maintaining the temperature at which the food was placed in the showcase), and not for freezing food.

Defrosting the evaporator of the refrigerated showcase

Defrost of a refrigerated showcase (refrigerated counter) can be manual or automatic, for example, a showcase "NAROCH" OV from Golfstream equipped with an automatic evaporator defrosting (thawing) system using tubular electric heaters - heating elements (4 defrosting per day, each with a maximum duration of up to 30 minutes). The defrost cycle is controlled by the electronic regulator (controller) of the showcase control unit. During the defrost phase, the air temperature read on the thermometer will be higher than the actual temperature of the displayed products, but will not exceed the limits stipulated by the regulatory documentation. After the end of the defrost phase, the temperature in the useful volume will quickly recover to the set operating value. During the evaporator defrost and until the set temperature is reached, the controller will display the temperature at the start of the defrost.
