Heat exchanger unit
The heat exchange unit is composed of a heat exchanger, a temperature control valve group, a drain valve group, a circulating pump (when the heat medium is steam), an electric control cabinet, a base, pipelines, valves, instruments, etc. It can also be equipped with expansion tanks, water treatment equipment, water pump frequency conversion control, temperature control valves, remote communication control, etc., thus forming a complete heat exchange station. The heat exchange unit has a standardized and modular design, complete configuration, easy installation, and high efficiency and energy saving. The heat exchange unit has the advantages of compact structure, reliable operation, and easy and intuitive operation, making it the preferred high-efficiency and energy-saving product. This product is suitable for sanitary hot water in residential areas, government offices, factories and mines, hospitals, hotels, schools, and other places. The integral heat exchange unit can be used for both water water exchange and steam water exchange.
This product is suitable for heating, bathing, and air conditioning systems in residential areas, government offices, factories and mines, hospitals, hotels, schools, and other places. The integral heat exchange unit can be used for both water water exchange and steam water exchange. The unit is composed of a heat exchanger, a circulating pump, a make-up pump, an electric control cabinet, a filter, a base, pipelines, valves, instruments, etc. It can also be equipped with automatic constant pressure make-up devices, water treatment equipment, water tanks, variable frequency control of water pumps, temperature control valves, remote communication control, etc., thus forming a complete heat exchange station. This unit has a standardized and modular design, complete configuration, easy installation, high efficiency and energy saving. It has been widely used in systems such as centralized heating in residential areas, central air conditioning, domestic water supply, and enterprise production process water supply.
Working principle
Plate heat exchanger is a system that automatically and continuously converts the heat obtained from the primary grid into the domestic and heating water needed by users. Hot water enters the plate heat exchanger from the primary inlet of the unit for heat exchange, and then flows out from the primary outlet of the unit; After the secondary side return water is filtered to remove dirt, it enters the plate heat exchanger through the secondary side circulating water pump for heat exchange, producing hot water at different temperatures for heating, air conditioning, floor heating, or domestic water to meet the needs of users.
The secondary water is filtered and purified, then circulated into the heat exchanger and heated by steam or high-temperature water for heating. After steam or high-temperature water enters the plate heat exchanger, it becomes condensed water or high-temperature return water and returns to the heat source for the loop circulation of the primary and secondary heating system. The water replenishment pump injects soft water into the system to maintain a constant system pressure.
