A cold drinker is a mechanical device made in combination for the purpose of cooling and storing drinking water such as electricity, electronics, machinery, and high-pressure gas (Freon refrigerant).

In the cold drinker,

In order to obtain a cooling effect by a mechanical method, the compressor (cooling compressor) occupies the largest proportion among the cold drinkers is the compressor and the evaporator of the drinking tank.

Compressor is a device that compresses low-temperature and low-pressure refrigerant gas and changes it into high-temperature and high-pressure gas. When the compressor compresses gas, the temperature rises in the adiabatic compression process of the gas and the temperature rises by the amount of heat equivalent to the work of the motor. If you hold the discharge pipe of the compressor, it may become hot depending on the operating condition of the cooler and cause burns.

In particular, since the length of the cold plate (cooling plate) of the chiller is short and the tank is operated without water, the temperature of the tank drops instantaneously, the refrigerant does not evaporate from the tank to gas, and the liquid compressor is also sucked. Since the cooling-reduced metal is weak in low-temperature brittleness, it can cause serious malfunctions in the compressor such as burnout, so it should not be operated in an empty state.

Condenser (machine room outdoor unit)

The high-temperature and high-pressure refrigerant gas from the compressor is condensed by throwing away heat in the air here, so it is called a condenser. In the machine room of the cold drinker, if you turn the fan blades in the shape of a honeycomb and force the blower to blow, hot air comes out. Depending on the ambient temperature, the temperature of the crude oil in the tank, or the amount of crude oil, hot or lukewarm wind may come out. have.

The fan (pinwheel) in the condenser may or may not rotate depending on the ambient temperature or the amount of crude oil.

Since the condenser is made of thin aluminum, it should be cleaned carefully so that the aluminum fins are not damaged. If the dust is severe, spraying a neutral detergent and cleaning with high pressure water is effective.

Tank (inner bottom plate cold plate = evaporator)

The tank plays the biggest role in the cold drinker, and all of them are currently plate-directed cooling.

The tank is the most important part to achieve the ultimate purpose of the refrigerator as it functions to store drinking water and to maintain, store, and supply cold drinking water by cooling it to the temperature desired by the consumer.

In the plate cooler currently used, when hot water or negative water is added to the tank when the empty tank is in excessive operating condition or when the tank cold plate is below freezing, the surface of the tank rapidly expands and the back surface is still contracted. It may lead to a fall accident, which may lead to malfunctions such as gas leakage from the tank. If an empty water dispenser is operated, the refrigerant liquid is sucked into the compressor as there is no cooling load, and the compressor freezes, causing damage to the compressor.

agitator

In order to obtain a uniform low temperature and good cooling effect of the negative water in the cold drinker, the negative water in the tank is forcibly vortexed with a stirring blade using a motor.

The agitator continues to operate for 3-5 minutes after cooling and stops for 30-60 minutes, and by performing such periodic stirring, it is possible to obtain the effect of preventing the temperature difference between the top and bottom of the cold drinking water. The size of the agitator motor is about 25W~100W and it generates a lot of heat in summer due to its closed structure.

reverse rotation of agitator

The agitator rotates forward during cooling or washing, but reverses only when washing and draining.

How to use the thermostat

A temperature controller is a device that gives commands such as operation or stop of the drinking water dispenser to cool the water to a set temperature and to maintain the set temperature even after cooling.

DIP S/W is built-in and used in order to be safe from the influence of others' erroneous setting or moisture or noise.

It is good to maintain the cooling temperature around 4-5℃. However, the present invention is not limited thereto. In the present invention, when the temperature of the water usually input is 19-20 ℃, it may be supplied by lowering it to 17-15 ℃ in the cold drinker.

It is possible to set from 0.1 degree to 1 degree by using the increase/decrease key.

Setting the temperature too low can cause negative water to freeze and the compressor to freeze and break, causing the stirrer to malfunction.

How to set up and use the washer of the cold drinker

automatic washing machine

Since the fully automatic washing machine is an electric and electronic program, it responds sensitively to even the slightest stimulus.

The cold drinker consists of a stainless tank, a refrigeration machine room, and an electric and electronic washing machine program. The washing machine is always exposed to water because hot and cold water is washed and drained by a fully automatic program. have to lean

It is an electronic device that stores and controls all functions such as washing sequence and time, detergent input time and washing water injection time as a program in one semiconductor chip.

How to use the washer

After emptying the tank, open the oil drain valve of the tank and check that there is no residual negative water. After tightening the connection nut of the washing hose, connect the hose of cold and hot water for water supply or turn the valve (if the valve is always connected, turn on the valve once a month). closure of leak check) and open.

Then, raise the wash cooling select switch (S/W) to wash.

When washing is selected, the washing display window up-counts in seconds. If you press the START button in standby mode, it proceeds to a down counter in seconds from mode 1, and water is supplied while pre-washing is in progress. At this time, the display window 1 point lamp is turned on, and when the time is over, the next mode is displayed and proceeds automatically in the order of pre-cleaning, alkaline cleaning, alkaline rinse, acid cleaning, rinsing 1, rinse 2, according to the program. When cleaning is complete, END is displayed. If you press the SKIP button while the program is in progress, one mode at a time, one step at a time.

How to set up a washing program

Time setting for each step

To set the time for each step, use a total of 2 switches, such as "mode switch" and "reducing switch".

The mode switch selects the stage to be set. Each press changes the mode from 1 to 25-

The increment switch increases the set value. Each press increases by 10 seconds.

The decrease switch decreases the set value. Each time it is pressed, it decreases by 10 seconds.

The minimum and maximum time that can be set for each step are as follows.

Maximum time: twice the existing maximum time

Minimum time: 1/2 times the existing minimum time

The operation contents of each step are classified as shown in Table 1 below by way of example.

How to use the cooling of the water cooler

When the cooling wash selection switch is lowered to Cool, the current temperature is displayed.

At this time, if the temperature is not displayed and displayed as LO, the sensor is disconnected or the temperature is below minus 9℃. If it is displayed as HI, it is over 69℃ or short circuit of the sensor or sensor lead wire.

Normally, if the selection S/W is lowered to cooling, the current temperature is displayed and a small dot at the right end of the temperature display window blinks once and the agitator is activated.

After 2-3 minutes, a small dot at the right end blinks twice, and machine room No. 1 (No. 1 in case of 2 single units) is operated.

After 30 seconds, a small dot at the right end blinks 3 times, and machine room #2 is activated.

Check before negative input

If there is residual washing water left inside the negative water cooling tank, do not put negative water into it.

Check whether the cooling temperature of the water cooler thermometer is appropriate.

In the event of a malfunction of the thermometer, forced cooling with the switch next to it results in forced cooling. However, since the temperature continues to drop and the refrigerator does not stop, in case of forced cooling, check the appropriate temperature and then manually turn off the forced cooling switch.

Negative numbers must not freeze.

If the temperature of the surface of the cold plate on the bottom of the tank is too low and the negative water freezes due to a lack of gas, a malfunction of the equipment, or too low a temperature setting, the temperature difference between the upper and lower negative water inside the tank becomes severe and it may be difficult to obtain the desired cold water.

cooling rate

The cooling capacity of a water cooler depends on many factors, such as the size of the tank, the cooling method, the size of the refrigeration machine room, and ventilation, but it takes time to cool even the most efficient cooler.

The water supply time will determine the user's sensory cooling rate, and the size of the water cooler or the type of machine room, sufficient power, ventilation in the machine room, and the amount of water supplied per hour determine the cooling rate.

Poor ventilation or poor voltage leads to a slow cooling rate and leads to compressor failure.

Precautions when installing a water cooler

There are two types of electricity used: single-phase 220V and three-phase 380V, and three-phase 380V is stable and has a low failure rate.

Grounding of the chiller

The chiller must be grounded by three types, the voltage must be higher than the rated voltage, and the temperature around the washing machine and water pipe can only be used at 5°C or higher, and the electronically controlled cold drinker is weak against lightning or moisture. Special management is required by the user so that the power is turned off (cut off) and there is no water or residue, detergent residue, etc. around the cold drinker.

When the cold drinker tank is empty, turn off the switch to never operate the empty cold drinker.

set it low

The lower the height of the cold drinker, the more convenient to use. The closed cold drinker automatically cleans but requires convenient daily management, so the lower the height, the more convenient to use. Since it is inconvenient, in the case of a closed type, the lower the value, the more convenient the management.

Since cleaning or inspection is required on a regular basis, the installation should be easy to inspect, repair, and clean.

The cold drinker needs regular inspection and observation. Also, it should be installed in a well-ventilated place.

Hot wind comes out of the condenser (radiator), and special attention must be paid to ventilation in summer. Holes should be drilled in the wall to the size of the machine room to ensure good ventilation.

When electricity flows in the wire, the electrical resistance of the wire impedes the flow of electricity.
