Specifically, this embodiment make full use of the radiant heat on the high temperature surface of heated kang ubiquitous in the northeast tradition peasant household, rational utilization solar heat radiation energy outdoor temperature is low simultaneously, the water system freezes easily and is difficult for the maintenance, cost and maintenance cost are higher, the main of adoption in this system, through effectual collection, transmission, storage with heatable brick bed surface heat radiation energy and solar heat radiation energy in the roof, through the radiation heating part of installing in the partition wall to the room in the radiation heating, and can be according to the temperature automatic switch operating mode. The working medium is air in winter in rural areas in the north. Meanwhile, the biomass fuel and agricultural production data are often stored in rural residences, dust is easily accumulated on the ground, and if hot air is directly sent into the residences, the dust is easily formed in the residences, the concentration of particulate matters such as PM2.5 is increased, and the rural residences are not beneficial to respiratory tract health of farmers. For this purpose, referring to a heating form of an electric radiation heat plate, the system is provided with an air radiation heat plate as a radiation heating means inside a farmhouse to radiatively heat the room.

Fig. 2 is a schematic diagram of the technical principle of the embodiment of the present invention, and as shown in fig. 2, the operation of the heat recovery type solar radiation heating system is mainly divided into an inner circulation mode and an outer circulation mode. The difference between the two is that in an external circulation mode, a first electric air valve (an electric air valve 1) is opened, a second electric air valve (an electric air valve 2) is closed, and air in the system mainly passes through a solar air heat collector, a kang surface radiant heat recovery device and a fan to form a loop; under the internal circulation mode, electronic blast gate 1 is closed, and electronic blast gate 2 is opened, and the system air does not pass through solar energy air heat collector, only forms the return circuit through heatable brick bed surface radiant heat recovery unit and fan, and the setting of check valve prevents that air leakage from flowing to solar energy air heat collector under the internal circulation mode.
Aiming at the problem that the solar air heat collector frosts in the morning due to the fact that the air temperature is too low, the solar air heat collector needs to operate for a period of time in an external circulation mode after the system is started. The temperature of the heated kang is increased due to cooking activities of peasant households in the morning, the air in the system can be preheated through the kang surface radiant heat recovery device to defrost the solar air heat collector, and the working state of the system under the condition is called as a preheating working condition. Through multiple field running experiments, the system runs for 2 hours in an external circulation mode to ensure complete defrosting.
After the solar air heat collector finishes the preheating mode, whether solar radiation energy can be effectively utilized or not needs to be judged according to the temperature of air at the outlet of the solar air heat collector, and then the electric control air brake is controlled to change the working condition.
Optionally, in the daytime with sufficient sunlight, the outlet temperature of the solar air heat collector can be rapidly increased, the indoor calculated temperature of the rural house energy-saving standard in winter is 14 ℃, the external circulation mode is maintained when the outlet temperature of the heat collector reaches 20 ℃ (the first set value) in consideration of pipeline on-way heat loss and radiation plate heat utilization efficiency, the air is heated by using solar radiation energy, and the indoor heat is supplied by using the heat radiation plate, and the working state of the system under the condition is called as a sunny working condition.
In addition, on cloudy days with insufficient sunlight, the outlet temperature of the solar air heat collector does not reach the set temperature, whether the kang surface radiant heat recovery device can effectively utilize the kang surface radiant energy or not needs to be judged, the indoor calculation temperature, the heat loss and the heat efficiency of the energy-saving specification are referred to, the outlet air temperature of the kang surface radiant heat recovery device is set to 15 ℃ (the second set value), the system works in an internal circulation mode, the air is heated by the kang surface radiant heat recovery device, the indoor heating is realized through the heat radiation plate, and the working state of the system under the condition is called as the cloudy day working condition. When the outlet temperature of the kang surface radiant heat recovery device does not reach the set temperature, the system should be in a standby mode, waiting for farmers to carry out cooking activities to improve the surface temperature of the heated kang and then provide kang surface radiant energy, and the working state of the system under the condition is called as a cloudy day working condition.
And finally, after sunset, the outlet temperature of the solar air heat collector is reduced to a set temperature, whether the outlet temperature of the kang surface radiant heat recovery device reaches the set temperature or not is judged, if so, the kang surface radiant heat recovery device is utilized to supply heat to the indoor space through the heat radiation plate, and the working state of the system under the condition is called as the night working condition.
Fig. 3 is a control logic diagram of the system in an embodiment of the present invention, as shown in fig. 3, wherein the preheating operation mode and the sunny operation mode are both operated in the outer circulation mode, and the cloudy operation mode and the night operation mode are both operated in the inner circulation mode. In order to facilitate the peasant household to use the system, the automatic startup, preheating completion and shutdown time can be set, the operation cost is saved, and the influence of night operation noise on the sleep of the peasant household is avoided. Meanwhile, the set temperature related in the control logic diagram can be set through the control panel in consideration of the diversity of the working conditions. After the time and the temperature are set, the system can automatically change the working condition through the control cabinet and the sensor to stably operate without additional operation of farmers, and an MCGS (controller control system) background operation strategy script written according to a logic diagram is operated.
