A kang heating terminal that takes into account both local and space heating

Abstract

The invention relates to a Kang heating terminal having both functions of local heating and space heating. The Kang heating terminal comprises an upper Kang plate, upper Kang plate bearing walls, bearing foundations, a U-shaped groove baseplate, an air flue dummy plate, a fan, an air port and circulating water pipes, wherein the upper Kang plate, the upper Kang plate bearing walls and the U-shaped groove baseplate are enclosed to form an air flue. The plurality of U-shaped circulating water pipes are pre-buried in the upper Kang plate; and one side of each U-shaped water pipe is buried in the upper Kang plate, and the other side of each U-shaped water pipe is exposed in the air flue. After hot water flows in a Kang body, the temperature of the upper Kang plate is increased to satisfy the Kang body surface and nearby local part heating requirements; under the effect of the fan, the forced-convection heat transfer is performed between air and the lower surface of the upper Kang plate and the exposed water pipes; and after the temperature is increased, the air is fed into a room to satisfy the space heating requirements. The Kang heating terminal retains the local heating advantages of a traditional heated Kang; and meanwhile, the Kang heating terminal enhances the space heating capacity, improves the temperature uniformity of the upper Kang plate, and can prevent the indoor air pollution caused by the leakage of combustion smoke.

Description

technical field [0001] The invention relates to a kang heating terminal, which belongs to the technical field of building heating in villages and towns, and is especially suitable for residential buildings in northern villages and towns that have both local and space heating requirements. Background technique [0002] Kang is the most commonly used traditional heating terminal in rural areas in northern my country. It uses the kang board with a large heat capacity to absorb and store the heat carried in the high-temperature flue gas generated by the combustion of the wood stove, and then dissipates heat to the room through the surface of the kang board to meet the local heating needs of the farm house. According to Tsinghua University's 2006-2007 large-scale rural energy environment survey data, in North China, Northwest and Northeast rural areas, the utilization rate of Kang reached 73.3%, 86.3 and 92.2% respectively (Building Energy Conservation Research Center of Tsinghua...

AI Technical Summary

Problems solved by technology

[0003] However, there are three main problems in the use of the heated kang: 1) the space heating capacity of the heated kang is insufficient, and the overall temperature of the room is low; The heat source has a single form, and there are hidden dangers of indoor air pollution;

However, the above improvement measures are still difficult to fully solve the three main problems existing in the heated kang, which to a certain extent restricts the application and development of the traditional heating end of the heated kang.
