High-efficiency water heat exchanger

Abstract

The invention relates to the field of water supplying and heat supplying and provides a high-efficiency water heat exchanger which saves electricity and energy and has the heat exchanging rate higher than that of the prior art to overcome the defects that in the prior art, the heat exchanging rate is too low, the cost is high and the practicality is too low. According to the technical scheme, the high-efficiency water heat exchanger comprises a water recovery device, a pure water providing device, a one-time heat exchanging device, a heat source water exchanging device, a pure water heat transmitting exchanging device, a water shunt set, a hot water storage device and a sewage storage device. The water recovery device and the pure water providing device are connected with the one-time heat exchanging device. The one-time heat exchanging device is connected with the heat source water exchanging device and the pure water heat transmitting exchanging device through the water shunt set, the heat source water exchanging device is connected with the sewage storage device, and the pure water heat transmitting exchanging device is connected with the hot water storage device. The heat source water exchanging device and the pure water heat transmitting exchanging device are further provided with Freon temperature rising devices.

Description

technical field [0001] The invention relates to the field of water supply and heating equipment, in particular to a high-efficiency water heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . Its types are 1. Surface heat exchanger. The surface heat exchanger is that two fluids with different temperatures flow in the space separated by the wall. Through the heat conduction of the wall and the convection of the fluid on the wall surface, the two fluids are exchanged. hot. Surface heat exchangers include shell and tube, casing and other types of heat exchangers. 2. Regenerative heat exchanger, the regenerativ...
