Description

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

technical field

The invention relates to a novel intelligent cold and hot water mixed constant temperature heating device, which belongs to the technical field of electric heat storage boilers.

Background technique

The R&D and application of Gudian thermal storage boilers has become the focus and hotspot of R&D in various countries in the field of energy conservation and environmental protection. At present, the technical methods of valley electricity thermal storage boiler technology are divided into two types: the first is to use cheap valley electricity at night to heat the thermal storage body, and store the heat in the thermal storage body. The heat in the boiler is blown into the wind-water heat exchanger through the pipeline, and the circulating water in the heating pipeline is heated by the wind-water heat exchanger to heat the building; the second is to use the valley electricity at night to heat the heat storage body, and make the water pass through the pipeline. Flowing in the heat storage body, the water absorbs the heat of the heat storage body and the temperature rises, and the high temperature water after the temperature rise is stored in the water storage tank. During the day, the high temperature water in the water storage tank is used to exchange water-water The heater heats the circulating water in the heating pipe to heat the building. However, in practice, these two methods have many limitations.

For the first method: due to the low heat exchange 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 duct is large, and the floor area is large. With the increase of heating area will be more obvious, or even impossible to implement. Moreover, the manufacturing process of the air-water heat exchanger is complicated, the price is high, and the hoisting and installation are difficult, which brings inconvenience to the popularization and application of the electric thermal storage boiler technology.

For the second method: some improvements have been made in solving the various shortcomings of the first method above, the air-water heat exchanger in the first method is cancelled, but a water storage tank is added, although the water storage The production process of the tank is simple, but the volume of the water storage tank is still huge and covers a large area. In addition, because the water flow continuously absorbs heat from the heat storage body during the night valley electricity 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.

Aiming at the above-mentioned shortcomings of the existing technical solutions of the valley electricity heat storage boiler, an economical and efficient valley electricity heat storage boiler product is provided by innovating the product structure and process technology of the heat storage boiler.
