The difference between electronic refrigeration and compressor refrigeration;
1, refrigeration mode: electronic refrigeration adopts electronic refrigeration sheet, with low noise and no pollution; Freon refrigeration is adopted for compressor refrigeration.
2. Cooling speed: The compressor has a faster cooling speed. When it is first used or recooled, the cold water temperature drops below 15% after 30 minutes, and the recooling time is shorter. The refrigeration time of compressor is about 20%-30% of the electronic refrigeration time.
3. Refrigeration effect: the lowest temperature of electronic refrigeration is 9- 1 1℃, and the lowest temperature of compressor refrigeration is 5-6℃.
4. Water output: electronic refrigeration: 0.7 liter/hour, compressor refrigeration: 2 liter/hour.
5. Applicable occasions: enterprises and institutions; Household users who have high requirements on refrigeration speed and refrigeration effect are also suitable for compressor refrigeration models. Generally speaking, ice heat refers to electronic refrigeration. Heating should belong to the category of thermal relay, which automatically turns on the power supply for heating at the set temperature, and then turns off the power supply after reaching the set temperature, and so on.
Functional differences among ice hot water dispensers, warm water dispensers and cold and hot water dispensers;
1, warm water dispenser
For the warm water machine used in the factory workshop or office, press the heating switch when taking water, and the indicator light displayed as "heat preservation" will immediately start the power supply and give work instructions.
In the warm drinking fountains of reform schools, or the direct drinking fountains, energy-saving drinking fountains and step-by-step water heaters in factory offices, the power supply is divided into two ways: one is the heating circuit, so that the heating system is electrified to raise the temperature; The other path provides electric heating indication for the "heating" indicator light. When the water in the water tank is heated to the set temperature, the temperature control sensing system is disconnected and the electric heating system stops heating.
When the water temperature is lower than 85 degrees, the temperature sensing system is connected to the power supply, and the electric heating system immediately heats up.
The computer version of the warm water machine has double protection. When the water dispenser generates heat or has a short circuit fault,
The overtemperature fuse immediately cuts off the power supply and plays a protective role. After troubleshooting, replace the new overtemperature fuse according to the original model and specification, and then press the reset button of manual reset thermostat by hand, and the contact can be closed to work again. 2. School hot and cold drinking fountains
When the direct-cooling cold and hot water dispenser is used, the school cold and hot water dispenser is directly connected with tap water, purified and all the way into a cold container, and cooled to produce cold water; The other path enters the heating water tank and is heated to generate hot water.
Press the cold water switch, the AC voltage is reduced by the power transformer, rectified by the rectifier diode and filtered by the capacitor, and then the DC voltage is output for the refrigeration of the semiconductor refrigeration element and the exhaust of the fan. At the same time, the cooling indicator lights up. Since the direct-cooling cold and hot water dispenser is not equipped with automatic temperature control, the refrigeration indicator light has been on since it was started.
3. Ice hot water dispenser
In factories, offices, railway stations and airports with a large flow of people, ice-hot water dispensers cooled by compressors are generally used. When the ice water button is pressed, the refrigeration indication system is started, and the compressor starts to operate, which sucks back the refrigerant vapor absorbed and gasified in the evaporator, compresses it into high-temperature and high-pressure gas, sends it to the condenser, and then radiates heat to the outside air through the condenser and condenses it into high-pressure liquid.
Then it flows into the evaporator through capillary throttling and depressurization, absorbs the heat of the cold water tank to reduce the water temperature, and then is sucked back by the compressor. This cycle achieves the purpose of cooling. The temperature of pure water cooled by compressor is about 4-7 degrees. Four innovative achievements of ice-hot water dispenser;
Patent innovation-health: multi-stage filtration of boiling water and warm water, high-temperature sterilization, and cooling of warm water after it is really boiled.
