Abstract

The invention relates to a direct heating-circulating type normal pressure dual frequency converting heat exchanger unit. Wastewater, waste steam (for example, waste steam generated by laundry rooms and dish-washing machines in canteens and waste steam generated in the process of making steamed buns), and waste smoke and waste gas of boilers burning gas, fire coal and oil are all discharged without being treated in colleges and universities at present, heat energy is lost, and the environment is polluted. The direct heating-circulating type normal pressure dual frequency converting heat exchanger unit comprises a heat exchanger unit body, one end of the heat exchanger unit body (4) is connected with an anti-freezing solution feed pipe (1), an anti-freezing solution discharge pipe (2) and a cold tap water feed pipe (3) through a pipe bundle, the other end of the heat exchanger unit body is connected with a hot tap water discharge pipe (5) and a hot tap water return pipe through a pipe bundle, and a hot water tank is connected with hot water supply tanks (9) through pipe bundles; the hot water tank is connected with the hot water supply tanks through the pipe bundles and a water distributor (8), and a variable frequency water pump (7) is additionally arranged in a pipe bundle loop. A heat exchange method is applied to the direct heating-circulating type normal pressure dual frequency converting heat exchanger unit.
