How to choose a heat exchanger unit? How to select a suitable heat exchanger unit for your needs?
English name of heat exchanger unit: Heatexchangerunit. This product is suitable for heating, bathing and air conditioning units in residential buildings, government agencies, factories, hospitals, hotels, schools, etc. The integrated heat exchanger unit is suitable for both water-to-water exchange and steam-to-water exchange. The heat exchanger unit is composed of a heat exchanger, circulating water pump, make-up water pump, electrical cabinet, filter device, base, pipes, gate valves, instrument panel, etc. It can also be modified with a fully automatic constant pressure make-up water device, water purification equipment, water tank, water pump frequency control, temperature control valve, remote communication operation, etc., to form a complete heat exchange station. The equipment features standardized and modular design, complete equipment, convenient assembly, and energy saving and environmental protection. It has been widely used in residential community centralized heating, household central air conditioning, drinking water, and factory production process water systems.
Principle of heat exchanger unit:
The plate heat exchanger unit continuously and automatically converts the heat obtained from the primary network into the drinking water and heating tap water needed by the customer. The hot water enters the plate heat exchanger from the primary side channel, conducts heat exchange, and is discharged from the primary side outlet; the secondary intelligent return water is filtered to remove impurities, and then enters the plate heat exchanger through the secondary side circulating water pump to conduct heat exchange, producing hot water of various temperatures for heating, central air conditioning, floor heating, or drinking water, to meet consumer needs.
The secondary water is filtered to remove impurities, enters the heat exchanger through the circulation system, and is heated by steam or continuously high-temperature water for heating. After the steam or high-temperature water enters the plate heat exchanger, it becomes condensate or continuously high-temperature intelligent return water back to the heat source, carrying out the control loop circulation system of the primary and secondary heating systems. The make-up water pump injects softened water into the system to maintain the stability of the output pressure.
Application structure:
1. Temperature control
Control the primary network flow rate using an electric butterfly valve to maintain the set temperature at the secondary network outlet.
Use an independent temperature control valve to control the primary network flow rate to maintain the set temperature at the secondary network outlet.
Adjust the outlet temperature of the secondary network according to the outdoor temperature.
2. Pressure, pressure difference control
Secondary side intelligent return water pressure difference control, secondary side intelligent return water pressure control
3. Automatic water replenishment
Variable frequency water replenishment and moisturizing, using the pressure signal of the secondary network return water to control the output of the variable frequency speed regulator to achieve automatic water replenishment and maintain stable pressure in the operating system.
Using an electric contact pressure gauge electrical control system, the on/off of the make-up water pump is adjusted based on the upper and lower limits of the secondary network system pressure to maintain stable pressure in the operating system.
