Description
Technical Field

With the continuous improvement of the material culture level of people, the air conditioner is widely applied as a household device for improving the living conditions of people. At present, in China, heating equipment is installed only in the northern area, and users who install floor heating in some southeast and central areas are gradually increased. In order to respond to the national sustainable development strategy, in the field of energy heat pumps, people are dedicated to research on how to effectively and reasonably distribute resources, utilize resources, reduce unnecessary energy consumption and improve the utilization rate of resources from different aspects such as energy, a heating system and the like.
The condensing furnace recycles the waste heat in the flue gas through a condensing waste heat recycling technology, has higher heat efficiency compared with the traditional boiler, and has the significance of energy conservation and environmental protection. However, the circulating pump inside the boiler mostly does not adapt to the direct circulation of the whole heating system, if two water pumps are arranged, due to the change of the operation load of the system, the different lifts and the different flow rates of the two water pumps can generate coupling conflicts, the coupling conflicts are overcome, the heating system is divided into a heat source side and a floor heating tail end side by utilizing a water mixer, and the primary circulating system and the secondary circulating system run independently.
For central heating users, the water mixing and heat exchanging system mainly has the advantages that the safety and the comfort of floor heating are improved, the device is used for converting hot water with high temperature difference and small flow into circulating water with low temperature difference and large flow, after the water mixing system is adopted, the circulating water with low temperature difference and large flow can be provided for the central heating users, and the requirements of floor heating on safety and comfort are met. In addition, the temperature of water born by a pert pipe adopted by the floor heating system is within 60 ℃, if the water supply temperature exceeds 60 ℃, a water mixing center needs to be added, otherwise, the service life of the pipeline is greatly reduced, and the toxic substances are released from the household building materials due to overhigh temperature. Therefore, water with the temperature higher than 60 ℃ can be limited in the primary side circulation system through the water mixer, and the mixed water with the temperature lower than 60 ℃ enters the ground heating pipe.
The existing water mixing and heat exchanging system is generally used for central heating users, the volume of the equipment is large, the system pipeline is long, and partial heat energy is lost when the mixed water is conveyed to each user home through the pipeline. The water mixing heat exchange system of the general household wall-mounted furnace is started and stopped by detecting the temperature difference of water supply and return water due to the operation of a heat source, when most heating areas are shut down and only a small part of the heating areas are started, a heating pipeline is short, the water supply and return speed is high, the requirement of heating cannot be met due to the fact that the heat source equipment is started and stopped excessively and frequently, and certain damage can be caused to the heat source equipment.
