Solar water heater is a type of water heater that we often use in our daily life, and it has gradually begun to be used in industrial production. Industrial solar water heaters are used in industry and can provide hot water in many areas, such as brewing and fermentation, product drying, production preheating, active and passive heating, etc.
In many food factories, air is needed to dry food. The required air temperature is 60 degrees. Some companies will use solar water heaters to do this. When the water temperature in the buffer water tank reaches or exceeds 60 degrees, an air heat exchanger is used to directly heat the production line. When the water temperature in the buffer water tank is lower than 60 degrees, a water source heat pump is used.eated to extract heat from the buffer water tank. After conversion by the compressor, it becomes high temperature heat and is used to heat the buffer water tank. production line through the finned condenser.
Boiler preheating installations can use solar water heaters. Plate heat exchangers are connected in series to the boiler return pipeline. When the water temperature in the buffer water tank is 15 degrees higher than the water temperature in the return water pipe, the system automatically starts the circulation pump between the plate heat exchanger and the water tank to transfer heat from the water tank to the return. boiler water line. It is estimated that this project will be able to recover all the investments in only about 3 to 4 years.
For example, in a soy sauce fermentation tank, water is required to maintain the temperature and avoid the loss of condensed water generated by daily steam heating. When designing a solar system. The water heater is used to detect regularly every day. If the temperature is lower than the required temperature of the water bath and the water temperature in the solar buffer water tank is 5 degrees higher than that of the water bath. The system will heat the water in the water bath via the plate heat exchanger. If the temperature is insufficient, an alarm will automatically sound to remind the service personnel to start steam heating. to ensure continuity of production.
The use of solar water heaters in industry can make full use of this cheap low-temperature heat source, make more adequate use of energy and reduce production costs for many companies. Today, theyt gained favor in the market and played a huge role in many industrial productions. I believe that as people's understanding continues to deepen, industrial solar water heaters will provide greater assistance to industrial production.
