The next day, after the morning meal at the eldest aunt's house, Jing Tian took the three little ones with great interest and came to the construction site of his small yard with Chen Liang.

The courtyard wall is still being repaired, but several main houses have already been built. Looking at the five big blue brick houses in front of them, the three little ones ran around excitedly from house to house.

Although this small courtyard is a farmhouse, it is extremely exquisitely repaired. The materials are all bought good green bricks and gray tiles, and the wood is not saved.

Chen Liang secretly went up to the mountains to hunt at night several times, and sold a lot of money to build a comfortable courtyard for Jing Tian. Seeing that he is so hearted, everyone is naturally happy to see it.

When Jing Tian and the others arrived, there were already four people waiting in the courtyard, and when they saw them coming, they stepped forward to say hello.

"This is Brother Changshui, the foreman who built the kang for us." Chen Liang smiled and introduced Jing Tian.

Jing Tian found that the burning efficiency of the stove in the village was not high. The mouth of the stove and the stove were very large, and there was no chimney, and every time the fire was lit, someone had to blow it with a blowtorch for a long time. If you're a novice, it's hard to burn and burn and extinguish.

And no one in the village uses a fire kang, everyone's kang is directly built with loess, adobe bricks, etc., to put it bluntly, it is just to build a higher platform for sleeping.

At this point, Jing Tian also inquired about it, the people of the Holy Tang Dynasty, if the conditions are better, they will make wooden beds, which is not a simple board bed like her previous life, but a bed and a couch, with pillars and cabinets at the corners, a complex piece of large furniture.

When a daughter gets married, she is married to a wooden bed, and most people will sleep on it for the rest of their lives, and when they die, it is also an inheritance that can be passed on to their children and grandchildren.

Like the people in the village, they can't afford to get up, so they use loess to build a higher platform, and the more elaborate ones are at most covered with adobe bricks.

At this time, it was already September, and the calendar of the Holy Tang Dynasty was about to be quite similar to the lunar calendar used by Jing Tian in his previous life, and the autumn harvest was about to be harvested at this time, and the sky was a little cold. Don't use a fire kang, just rely on a few braziers to survive the winter, which Jing Tian can't imagine.

The structure of the main house, in the middle, is still a hall house, but it is much wider than the average one. Because when Jing Tian designed, he planned for four of them, one person in one main room, all of them on the fire kang.

It's okay to set up a stove, as long as you adjust the stove mouth and stove slightly, add the stove grate and chimney, and then turn down the hanging fire. In this way, the overall structure of the improved stove is more reasonable, and the interior is a complete air circulation system, which can make the firewood burn more fully and the combustion efficiency higher.

Moreover, Jing Tian is directly designed with a four-hole chain stove, with two large pot tables and two small stove openings, as long as the insulation layer between the stove is opened, the big pot here cooks rice, and the small stove there cooks soup, which is very practical. In addition, iron stove lids and stove rings are added to the small stove opening, and when the water is not boiling, the lid can be closed to bake things.

The main stove designed by Jing Tian is at the back of the Dongzheng House, and one of the small stoves can be used as the fire outlet of the Dongzheng House's ondol.

In fact, the structure of the fire kang is far more complex than imagined, and Jing Tian also saw the general method in the sharing of a WeChat circle of friends in his previous life, and he pondered for a long time before drawing the design drawing.

The key is that the placement of each brick in the kang cavity is exquisite, depending on the direction, size and shape of the house, and the position is slightly deviated, and the air duct may not be smooth. Burning the hot kang is still secondary, and it may also cause smoke to pour in.
