The role of PCBA in drinking fountains
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
Almost every household has such a water dispenser. Few people know the working principle of the water dispenser. It is driven by the built-in PCBA to realize its cooling and heating principles.
(1) Principles of water dispenser refrigeration
1. Press the refrigeration switch, the power is turned on, the refrigeration green indicator light is on, and the compressor starts to run. 2. The compressor sucks the refrigerant vapor that has absorbed heat from the evaporator, compresses it into a high-temperature, high-pressure gas, and sends it to the condenser. 3. The refrigerant vapor dissipates heat to the outside world through the condenser to condense into a high-pressure liquid. Then it flows into the evaporator through capillary throttling and pressure reduction, and absorbs the normal temperature hydroelectric heat of the cooler, so that the water temperature is reduced, and the refrigerant liquid is sucked back by the compressor, so that the continuous circulation truly achieves the purpose of cooling. 4. When the water temperature drops to the set temperature with time, the refrigeration thermostat contacts are disconnected, the refrigeration green indicator light goes out, the compressor stops and turns to the heat preservation state. 5. After the power is off, the water temperature gradually rises. When it reaches the set temperature, the contact action of the refrigeration thermostat is closed, the green indicator light is on when the power is turned on, and the compressor is running. In this way, the water temperature is controlled between 4-12°C.

(2) Heating principle
1. Press the heating switch, switch on the power supply, the heating circuit is connected, the red heating indicator light is on, and the electric heating tube heats up. 2. When the water temperature reaches the set temperature, the automatic reset thermostat will automatically cut off the power supply, the red heating indicator light will go out, and it will switch to the heat preservation state. 3. After the power is off, the water temperature gradually drops to the set temperature, the thermostat contact action is closed, the power is turned on, the red heating indicator light is on, the electric heating tube heats up again, and the water temperature in the water dispenser is controlled to be between 85-95℃. between. The compression type refrigerating water dispenser uses a temperature safety control device. When the circuit is overheated, the protection device will automatically fuse or disconnect the circuit when it is overloaded, which plays a role of safety protection.
