AI Technical Summary

Technical Problem

Traditional plate heat exchanger units rely on external water sources for their water supply systems. These systems require a large area, are costly, and are difficult to apply when there is no water source available at the user's site or when installation space is limited.

Method used

The system directly replenishes the secondary network with water from the primary network, and uses pressure sensors and control cabinets for automated control. It achieves precise water replenishment through the coordinated action of solenoid valves and electric regulating valves, and ensures stable system operation by combining flow meter monitoring and bypass pipelines.

Benefits of technology

It achieves automatic water replenishment without the need for an external water source, simplifies the system structure, reduces costs, expands application scenarios, improves the operational reliability and continuity of heating systems, and has intelligent and convenient maintenance capabilities.

Abstract

The utility model discloses a novel plate heat exchanger unit system, including detachable plate heat exchanger, hot side pipeline, cold side pipeline, control cabinet and the water supplement system of integration in the hot side export. Water supplement system is connected with filter, solenoid valve, electric regulating valve, flowmeter and manual ball valve in proper order and is detected two network pressure through pressure sensor on the cold side pipeline, and the opening and closing and the opening of water supplement valve are automatically controlled by control cabinet, and the water supplement of two networks is directly used to one network water source. The system has saved traditional water supplement pump and water tank, has compact structure, low in cost, water supplement automation, maintenance convenient and the advantages such as, effectively solved the two network water supplement problem of no external water source or space limitation on the spot.
