Energy-saving kang with double flow channels

Abstract

An energy-saving kang with double flow channels belongs to the technical fields of the utilization of solar energy and biomass energy and the building energy conservation. The energy-saving kang with double flow channels contains not only a stove, a kang plate, a flue baffle plate, a flue gas inlet, a flue gas circulation channel, a flue gas outlet, a chimney and other parts of the traditional kang, but also a solar air heat collecting system. In the energy-saving kang, the folded metal plate on the lower surface of the upper kang plate is utilized to increase the heat-transfer intensity of the air and the kang plate and the uniformity of the temperature distribution of the kang surface; the baffle plate is used to effectively separate the air and the flue gas circulation channel; and the solar energy and the heat of the flue gas can be utilized simultaneously, and the solar heat collecting device can not be damaged. All the parts in the energy-saving kang are prepared from common materials and by common preparation technology, thus the energy-saving kang has the advantages of simple production technology, low production cost and the like. The energy-saving kang is mainly used in the single building of a village in Northern China, can solve the indoor heating problem in winter and can reduce the coal consumption while lowering the environment pollution.

Description

technical field [0001] The invention relates to a heating facility in a single building in a village or town, in particular to an energy-saving kang capable of simultaneously utilizing solar energy and flue gas heat for indoor heating, and belongs to the technical fields of solar energy, flue gas heat utilization, and building energy conservation. Background technique [0002] Today, when traditional energy sources (such as coal, oil, etc.) are increasingly tense, renewable energy sources (such as solar energy, wind energy, water energy, biomass energy, etc.) have made great progress as alternative energy sources. In the northern part of my country, there is abundant sunshine, which belongs to the I, II and III areas of solar energy utilization ([1] Chris C.S.Lau, Joseph C.Lam, Liu Yang, Climate classification and passive solar design implications in China, Energy Conversion & Management, 2007 : 2006~2015), so solar energy utilization has a good development prospect in northe...

AI Technical Summary

Problems solved by technology

[0003] The main problems of the kang in rural areas of our country are: 1) uneven temperature distribution on the surface of the kang - the head of the kang is hot and the tip of the kang is cold, which can easily cause people's discomfort

2) Most of the kangs currently designed can only use flue gas as a heat source, but the relatively abundant solar energy resources in the northern region have not been rationally utilized in the kang system

Though existing some add pebbles (application (patent) number: 200920315844, solar energy kang) in the kang hole, or utilize solar energy (application (patent) number: 200520020506 solar energy) However, due to the difficulty of construction, limited resource conditions or initial investment, these systems have not been widely promoted in rural areas
