A new type of intelligent hot and cold water mixed constant temperature heating device

Abstract

The invention discloses a new type of intelligent hot and cold water mixed constant temperature heating device, which relates to the technical field of electric heat storage boilers; The bottom is connected to the heat storage device through the cooling water pipe, and the bottom of the heat storage device is connected to the middle part of the mixing tank and the cooling water tank through the return pipe, and the third valve is installed on the return pipe connected to the middle part of the cooling water tank, and the mixing tank The top of the heat storage device is connected with the water supply pipe, and the second valve is installed on the water supply pipe, and the bottom of the heat storage device is connected with the drain pipe through the water outlet pipe, and the fifth valve is installed on the water outlet pipe. The heat storage body in this device has no water flowing through the heat storage body during the heat storage period, and the cooling water tank is used to replace the traditional heat storage tank, which overcomes the inherent shortcomings of the two traditional electric heat storage heating methods, making the electric heat storage boiler The efficiency has been improved compared with the traditional one, and the occupied area is reduced by 50%.

Description

Technical field [0001] The present invention relates to a new type of intelligent cold water mixing constant temperature heating device belonging to the technical field of electric storage boiler. Background technique [0002] R & D applications for Valley electric storage boilers have become the focus and hotspots of countries in various countries in energy conservation and environmental protection. At present, the technical method of the technology realization of Gugu Electric storage boiler is divided into two types: the first is to use the low-cost valley electric heat storage in the night, store heat in the heat storage body, during the day peak, use the fan The heat in the boiler is blown into the feng shui heat exchange through the pipe, and the circulating water in the heating pipe is heated by the air-water heat exchanger as building heating; the second is to make water through the pipe while using the night valley electric heat storage. In the heat storage, the temperat...

Problems solved by technology

However, in practice, these two methods have many limitations

[0003] For the first method: due to the low heat transfer efficiency of the air-water heat exchanger and the small specific heat of the air, the air-water heat exchanger is bulky, the diameter of the air pipe is large, and the floor space is large. The increase of the heating area will be more obvious, and even impossible to implement

Moreover, the manufacturing process of the air-water heat exchanger is complex, expensive, and difficult to hoist and install, which brings inconvenience to the popularization and application of electric heat storage boiler technology

[0004] For the second method: some improvements have been made in solving the various shortcomings of the above-mentioned first method. The air-water heat exchanger in the first method has been canceled, but a water storage tank has been added. Although the water storage The manufacturing process of the tank is simple, but the volume of the water storage tank is still huge and occupies a large area

In addition, due to the continuous absorption of heat from the heat storage body by the water flow during the night valley power heat storage period, it is difficult to increase the temperature of the heat storage body, which reduces the utilization rate of the heat storage body
