Abstract

The invention relates to water-mixing regulating method and device of a secondary network system of a heat exchange unit, aiming to solve the cost problem of the traditional heat exchange unit. The water-mixing regulating method of the secondary network system of the heat exchange unit comprises the following steps of: realizing the heat exchange of two paths of liquid having temperature difference, wherein one path of liquid connected with a hot source or a cold source in series is called as a first network and the other path of liquid connected with the user terminal in series is called as a secondary network; connecting a passage in parallel between the input end and the output end of a plate-type heat exchanger on one path of the secondary network, accessing one part of the liquid of the secondary network to the plate-type heat exchanger for heat exchange, directly mixing the other part of the liquid with the output end of the plate-type heat exchanger via the parallel connected passage and then outputting the liquid. After the passages connected in parallel are increased in the secondary network system, the water flow entering the plate-type heat exchanger is reduced by 30 to 50% compared with the water flow before.

Description

technical field

[0001] The invention relates to a hot water central heating system, and further relates to a method and device for regulating mixed water in a secondary network system of a heat exchange unit. Background technique

[0002] In recent years, the energy-saving effect of floor heating is better than that of ordinary heating methods, and has been widely used. The characteristics of floor heating heating methods are that the secondary network water flow is large, the temperature difference is small, and the temperature difference is 5°C. The general floor heating system secondary network The water flow is 2 to 3 times that of the primary network, so the area of ​​the plate heat exchanger in the heat exchange unit will increase a lot. Contents of the invention

[0003] The purpose of the present invention is to solve the problem that in the existing heat exchange unit, when the water flow rate of the primary network / the water flow rate of the secondary network is ...
