Plate type water water heat exchanger unit

The concept and application of heat exchange units

An intelligent heat exchange unit is an electromechanical device that integrates heat exchangers, circulation pumps, make-up water pumps, instruments, filters, sensors, electrical controls, and valve pipelines to achieve overall heat exchange between fluids. And scientific calculation and optimization design are carried out, which has the advantages of excellent hardware configuration, reasonable structural layout, advanced control system, convenient operation and management, and cost saving. It can provide integrated heat exchange comprehensive solutions for users with different needs, and has been widely applied to regional heating/Refrigeration systems, domestic hot water systems, waste heat recovery, seawater desalination process cooling systems, and many other fields.

Intelligent heat exchange units have the advantages of high efficiency, energy saving, intelligence, and automation. They can be widely used for heating, air conditioning, water supply, domestic hot water, swimming pool and winter water supply in civil buildings such as factories, offices, schools, residential communities, villas, commercial buildings such as shopping malls, hotels, restaurants, and resorts. They can also be used to prepare industrial production process water and various places that require heat exchange.
In addition, it is suitable for closed cooling water systems and some special heat exchange conditions in industry.

Common problem solutions for heat exchange unit systems

1.Leakage of the thermostat:

phenomenon---The heating system suffers from severe water loss, and the water replenishment pump in the central area works frequently;

solve a problem---Re seal the graphite gasket and tighten the flange again;

2.Electric actuator module detachment:

phenomenon---The water supply temperature is too high, and the electric actuator is not functioning

solve a problem---Disassemble the electric actuator, reinsert the module, and check if the electric actuator is working;

3.Malfunction of pressure reducing valve:

phenomenon---When the steam consumption is low, the pressure reducing valve fails;

Possible problem: Dirty blockage of pressure reducing valve (such as welding slag); Excessive water accumulation in the pressure reducing valve

Solution: Disassemble the pressure reducing valve and connecting pipe to drain water; Disassemble the pressure reducing valve for cleaning; Add a filter before the pressure reducing valve; Add drainage before and after the pressure reducing valve;

4.Poor drainage of the unit:

Phenomenon: The condensate water connection point of the unit to the water tank is approximately high3Rice, causing the backflow of condensed water and poor drainage;

Solution suggestion: Directly discharge into the trench; Pump into the water tank

5.Heating and heating pipelines without pressure or heat:

Phenomenon: No pressure or heat in the pipeline

Possible reasons: Incorrect pipeline connection; Excessive air in the pipeline

Solution: Conduct pressure tests for each area, install pressure gauges, measure pressure at the highest point, and exhaust in the pipeline well

6.The water replenishment pump and circulation pump make noise

Possible problem: There is air inside the pump body

Solution: Exhaust the pump
