Composition Of Heat Exchange Unit And Functions Of Each Equipment

Our company's high-efficiency, intelligent heat exchanger units offer high heat transfer efficiency, low flow resistance, compact structure, reliable operation, and simple, intuitive operation. They are ideal for centralized heating in thermal power plants, district heating systems using boilers, and heating systems utilizing industrial waste heat. They can be used for heat exchange between various media, including steam-water, water-water, and oil-water. Providing comfortable and efficient heating, they are energy-efficient and environmentally friendly. They can be widely used in heating and air-conditioning systems in factories, government offices, schools, shopping malls, hotels, residential buildings, enterprises, and institutions, as well as in various other locations requiring heat exchange, ensuring a warm and comfortable working and living environment that meets production process requirements.

The circulating water system operates as follows: The primary heat medium (steam and high-temperature hot water) from the heating network or boiler flows through a heat exchanger at the required flow rate, controlled by an intelligent temperature control device. This heat is then transferred to the system's secondary return water. This secondary return water first enters a sludge filter, where solid particles, suspended matter, and impurities are filtered out. It then enters a circulating water pump, then a heat exchanger, where it absorbs heat and is then supplied to the user. The supply water temperature is automatically controlled by the intelligent temperature control device.

1. When the makeup water pump is controlled by power frequency, the upper and lower limits of the electric contact pressure gauge are set according to the secondary return water pressure. When the secondary return water pressure falls below the set lower limit, the makeup water pump automatically starts to increase the pressure; when the pressure reaches the set upper limit, the makeup water pump automatically stops.

2. When the makeup water pump is controlled by variable frequency, the actual operating pressure is compared with the set secondary return water pressure. If the actual value is lower than the set value, the makeup water pump frequency is increased; otherwise, the makeup water pump frequency is reduced until the actual pressure reaches the set value.
