Heat exchanger units at heating stations
1.What is the core equipment of a heat exchange station unit?
A: It is the core equipment of the centralized heating system, undertaking the key heat exchange task of connecting high-temperature heat sources (such as municipal heating networks) with the end-user side, and is the core hub to ensure stable heating supply.
2.What kind of heat transfer can the heat exchange station unit achieve?
A: It can achieve efficient heat transfer between the primary network (high-temperature hot water, usually from the heat source plant) and the secondary network (low-temperature hot water on the user side), avoiding direct entry of high-temperature heat sources into the user system and protecting terminal equipment.
3.How much can the energy consumption of the heat exchange station units be reduced?
A: With the addition of variable frequency energy-saving technology, energy consumption can be reduced by 15%-30%; the core of this technology is to dynamically adjust the speed of the circulating pump and the water supply pump to avoid the equipment always running at full load and reduce energy waste.
4.What are the advantages of a shorter installation time for heat exchange station units?
A: The modular design allows all core components (heat exchangers, pump sets, and control systems) to be prefabricated, assembled, and tested in the factory. On-site installation only requires connecting pipes and power, reducing the installation cycle by more than 50% compared to traditional component installation.

6.What is the heating water supply temperature of the heat exchange station unit?
A: The temperature of the secondary heating network water supply can be stably raised to 45-60℃. This temperature range can meet the indoor heating needs of residents (usually the room temperature is 18-22℃) and avoid pipe damage caused by high temperature.
7.Can the heat exchange station unit regulate system pressure?
A: Yes, it can automatically adjust the secondary network system pressure to 0.3-0.6 MPa through a linkage between the water supply pump and the pressure sensor, preventing water loss due to excessively low pressure and damage to pipes and valves due to excessively high pressure.
8.Does the heat exchange station unit have a fault alarm function?
A: Yes, the system monitors the equipment's operating status in real time (such as pump current, sensor data, and valve opening). If any abnormality occurs (such as sensor failure or pump overload), it will immediately issue an audible and visual alarm and display a fault code for easy and rapid troubleshooting.
9.Are heat exchange station units suitable for hospital settings?
A: Yes, it is suitable. It not only meets the heating needs of hospital wards and outpatient buildings, but also provides a stable supply of domestic hot water (such as for washing and disinfection in wards). Its stable operation and low noise also meet the requirements of the hospital environment.
10.Is there an upper limit to the operating noise of the heat exchange station unit?
A: Yes, the operating noise level is ≤75dB(A). This value references indoor and outdoor noise standards (such as 55dB(A) for daytime noise in residential areas and 70dB(A) for industrial areas), so it will not cause noise interference even if installed in an indoor machine room.
