Description

A kind of convection type heating heated kang

Technical field

The utility model relates to a kind of heating heated kang, belongs to the building and heating equipment technical field.

Background technology

Northern China cold and severe cold area life in the countryside are cooking and heating with the major part of energy, and wherein heating energy consumption occupies significant proportion.The traditional heating system in rural area comprises heated kang, wall with flues, stove and native heating installation etc., and heated kang still is widely used so far as the most ancient heating system of China.According to the statistics of Liaoning Province's rural energy office, by the end of the year 2004, the whole nation has 6,685 ten thousand to make the bed approximately, population in use reach 1.75 hundred million (Zhuan Zhi. the flow of flue gas of Chinese a heatable brick bed and Study on Heat Transfer, Dalian University of Technology's doctorate paper, in June, 2009, P2.).Use heated kang to heat under construction and not only can realize utilizing biomass energy to improve indoor thermal environment, and can realize reducing the target that commercial energy consumes.

But,, cause traditional heated kang aspect thermal characteristics, to remain in a lot of weak points because the design of heated kang lacks the theoretical foundation support mainly based on experience among the people at present.According to investigations, tradition is landed the thermal efficiency of a heatable brick bed a heatable brick bed body and is approximately 14～18%, and the thermal efficiency of kitchen range also has only about 8～10%, and kang-linked kitchen stove integrated heat efficiency less than 45% (Guo Jiye. northern firewood-saving and coal-saving kang-linked kitchen stove technology lecture (two), rural energy, 1998 (6): 12-14.).Traditional in recent years heated kang have be used gradually commodity can heating system such as the trend that substitutes such as native heating installation, domestic boiler, air-conditioning, go down for a long time and will increase the weight of the fuel in China's rural areas supply pressure.

In addition, there is the contradictory problems that satisfies simultaneously between room heating load demand and a heatable brick bed surface heat comfortableness target in actual applications in tradition heated kang, when indoor will reach than higher thermal comfort the time, just need the more fuel of kitchen range internal combustion, finally certainly will cause a heatable brick bed plate surface temperature higher, cause that the part is too hot, dry, phenomenon such as get angry.

For these reasons, and characteristics such as the Regional Distribution of considering a heatable brick bed is wide, number of applications is many, the energy-saving and emission-reduction potentiality are big, being necessary to take reasonable manner that traditional heated kang is rationalized transforms and Organic Renewal, when realizing improving heated kang, can also effectively improve the thermal comfort on a heatable brick bed surface to the indoor heating ability.
