Intelligent adjustment solar heatable brick bed based on human body thermal comfort

Abstract

The invention provides an intelligent adjusting solar heatable brick bed based on human body thermal comfort. The intelligent adjusting solar heatable brick bed mainly comprises a heatable brick bed body, a solar heat collecting system and a thermal comfort detecting and temperature adjusting system. The heatable brick bed body is heated by capillary tubes and is divided into at least two temperature zones, the temperature requirements of different parts of a human body are met, and at least one vertical face of the heatable brick bed body is provided with a radiating tube to provide heat for a room. The solar heat collection system can provide hot water for the heatable brick bed body and can also provide domestic hot water for users, and the utilization rate of the system is increased. And the thermal comfort detection and temperature regulation system comprises a kang surface temperature sensor group, an indoor air temperature sensor, a wall surface temperature sensor group, a central processing unit and a control panel, can calculate a human body sleep state PMV value through input temperature parameters, and provides a basis for temperature regulation and control of the solar kang. Solar energy is fully utilized, capillary tube radiation heating is adopted, intelligent control is carried out according to thermal comfort indexes, and good thermal comfort and energy-saving effects are achieved.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of solar energy, in particular to an intelligently regulated solar kang based on human thermal comfort. Background technique [0002] In rural areas in northern China, nearly 85% of rural households and about 175 million people use kang for family heating in winter. The traditional kang usually burns biomass fuels such as straw, stalks and wood to maintain the waste heat of the stove, gradually releases heat after combustion, and heats the room through the heat storage of the kang body. This traditional kang is commonly known as "hot kang". [0003] Due to the large number of kangs in rural areas burning biomass fuel, there is always severe air pollution during the heating season in rural areas of northern China every year. Moreover, the traditional heated kang has the following problems: smoke leaks, which pollutes the indoor environment, and sometimes the indoor personnel are...

AI Technical Summary

Problems solved by technology

To solve the problem of low energy utilization efficiency of traditional kang; smoke leaks, pollutes the indoor environment, and sometimes causes carbon monoxide poisoning due to the use of coal powder to simmer the kang; the thermal inertia is large, and the temperature cannot be adjusted in time; the temperature distribution of the kang surface is uneven, and even overheating causes a fire And other issues
