Working principle of spiral tube heat exchanger unit

A tubular heat exchanger unit is a device that converts heat from refrigerant into the required domestic and heating water for users, automatically and continuously. Hot water (or steam) enters the tubular heat exchanger from the refrigerant side inlet of the unit for heat exchange, and then flows out from the refrigerant side 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 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 enters the heat exchanger and is 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 primary and secondary heating system circuit. The pump pumps soft water into the system to maintain a constant system pressure
