Convection heating Kang

Abstract

The invention discloses a convection heating Kang, and relates to the technical field of building heating equipment. The Kang comprises a Kang face plate and an outer Kang body; an inner Kang body is arranged in the outer Kang body, so that a sealed air flow channel between the inner Kang body and the outer Kang body is formed; one end, positioned on the bottom of the inner Kang body, of the air flow channel is provided with a fan; one end, positioned on the side of the outer Kang body, of the air flow channel is provided with an air outlet; the inner Kang body is a rectangular cylinder with openings at two ends; outer side and inner side surfaces of the rectangular cylinder are both provided with fins; and one end of the rectangular cylinder is connected with a smoke outlet of a stove and the other end of the rectangular cylinder is connected with a smoke outlet of the Kang. The inner Kang body of the Kang serves as a heat exchanger for hot smoke and air, can improve the overall heat supply capacity of the Kang, effectively solves the problem that a common Kang has insufficient capacity of heating indoor air, and ensures that the Kang meets sleeping comfort and meets the comfort requirement of all-day indoor thermal environment in winter simultaneously.

Description

technical field [0001] The invention relates to a heating kang, which belongs to the technical field of building heating equipment. Background technique [0002] The main part of rural domestic energy consumption in the cold and severe cold areas of northern my country is cooking and heating, of which heating energy consumption accounts for a large proportion. The traditional heating methods in rural areas include heated kangs, flue walls, stoves, and soil heating. As the oldest heating method in China, heated kangs are still widely used today. According to the statistical results of Liaoning Provincial Rural Energy Office, as of the end of 2004, there were approximately 66.85 million kangs in the country, and the population of users reached 175 million (Zhuang Zhi. Research on the flue gas flow and heat transfer performance of Chinese kangs, PhD thesis of Dalian University of Technology, June 2009, P2.). Using kang for heating in buildings can not only realize the use of ...

Problems solved by technology

[0003] However, because the current design of the heated kang is mainly based on folk experience and lacks theoretical support, there are still many deficiencies in the thermal characteristics of the traditional heated kang

According to investigations, the thermal efficiency of the traditional floor kang body is about 14-18%, and the thermal efficiency of the stove is only about 8-10%. 2), Rural Energy, 1998(6): 12-14.)

[0004] In addition, in the practical application of the traditional heated kang, there is a contradiction between meeting the heat supply demand of the room and the thermal comfort target of the kang surface at the same time. When the indoor thermal comfort is to be relatively high, it is necessary to burn more fuel in the stove. In the end, it will inevitably lead to the high surface temperature of the kang board, causing local overheating, dry mouth, and getting angry.
