Model Meaning
In the series of diversion-type semi‑volumetric heat exchangers, the HRV features U‑shaped plain tubes, while the BHRV uses U‑shaped corrugated tubes.
Performance Features
- The heat exchange section is of an improved design, enabling rapid heat transfer, with a high heat transfer coefficient and a large heat transfer capacity. Compared with conventional half‑volume heat exchangers of the same type, its water production rate is 2 to 3 times higher.
- High water production efficiency, capable of continuously supplying hot water. , suitable for applications involving continuous water use.
- The water storage section is typically designed to hold a heat capacity sufficient for 15–20 minutes. Compact tank body, lightweight, easy to install and maintain. 。
- Add tube bundle securing devices to prevent damage during long-distance transportation. , which may lead to issues such as deformation, displacement, or fracture of the restraint.
- The structural design is rational, ensuring that the entire water storage section has no dead zones. The space utilization rate is as high as 100%. 。
- More thorough heat exchange, The condensate outlet temperature can be as low as 60°C, further enhancing energy efficiency. 。

Frequently Asked Questions
Precautions for Shutting Down a Plate Heat Exchanger
When shutting down the heat exchanger, first slowly close the hot-side inlet valve, then slowly close the cold-side inlet valve, and finally close both the cold- and hot-side outlet valves. After all valves are closed, stop the pump; if necessary, open the drain valve.
Precautions for Starting a Plate Heat Exchanger
Inspect the clamping bolts and tighten them to the specified torque, ensuring even diagonal tightening. Verify that the inlet and outlet valves and the vent valve are in good condition and that all instruments are functioning properly. During startup, vent the system first, then introduce the cold medium before introducing the high‑temperature medium. Gradually open the inlet and outlet valves while carefully controlling the pressure differential between the two sides.
Precautions for Disassembling Plate Heat Exchangers
Before dismantling the plate heat exchanger, the clamping dimensions shall be measured and recorded. L; Loosen the clamping bolts alternately in a diagonal sequence.
Precautions for Storing Plate Heat Exchangers
Plate heat exchangers should be stored in a dry, well-ventilated warehouse, with the ambient temperature not exceeding 45 °C 。
When a plate heat exchanger has been out of service for more than six months, the internal fluid must be completely drained. It is advisable to loosen the clamping bolts in advance to ensure that the gap between the two clamping plates reaches 1.2 times L is recommended; clamp it to L when in use.
Causes of Leakage in Plate Heat Exchangers
1) Gasket aging; 2) System overpressure; 3) Loose clamping bolts causing external leakage; 4) Plate corrosion leading to internal leakage.
