The invention also discloses an indoor temperature control method, which comprises the following steps:
the indoor space is divided into a plurality of areas, and a honeycomb type air outlet 2-1 and an electric heating sheet are installed in each of the divided areas. Wherein, the area blocking principle: firstly, drawing a planar two-dimensional pixel map (the density of a local color block is high, the density of the color block is low) according to the density of an indoor object, taking n points (about one point every 15 square meters) on the map based on the average point of the actual indoor area, then carrying out a region growing block dividing principle (retrieving unlabeled pixel points near the points, if the difference value of the unlabeled pixel points is within a specified threshold value, merging the unlabeled pixel points into a dividing region), roughly dividing n regions by the method, and carrying out detail optimization (boundary line angulation) on the shape of the n regions so as to achieve that the area of each region is about 15 square.

In the refrigerating process, after the variable frequency host 1 operates, the temperature sensors 4 on the surrounding walls input the collected temperature data into the host, the insulating layer partition board 2-3 and the air outlet panel 2-5, and the variable frequency host 1 performs frequency conversion once according to indoor uniform temperature to adjust output power. In the frequency conversion process, taking a frequency conversion host of 10-90 HZ as an example, when in refrigeration: when the real-time temperature equalization (T current)/set temperature (T set) > = 1.2, the adjusting frequency is between 70 and 90 HZ; when the real-time temperature equalization (T current)/set temperature (T set) > = 1.15 and <1.2, the adjusting frequency is between 50 and 70HZ; real-time temperature equalization (T current)/set temperature (T set) > = 1.1 and <1.15, and adjusting the frequency between 30 and 50HZ; real-time temperature equalization (tset)/set temperature (tset) > = 1.05 and <1.1, the adjusting frequency is 10HZ to 30HZ. When heating, the method comprises the following steps: the algorithm is the same as that in refrigeration, and the heating set temperature (T set)/real-time temperature equalization (T present) is brought into the algorithm for realizing temperature control based on indoor subareas, namely: when the real-time temperature equalization (T current)/set temperature (T set) > = 1.2, the adjusting frequency is between 70 and 90 HZ; when the real-time temperature equalization (T current)/set temperature (T set) > = 1.15 and <1.2, the adjusting frequency is between 50 and 70HZ; real-time temperature equalization (T current)/set temperature (T set) > = 1.1 and <1.15, and adjusting the frequency between 30 and 50HZ; real-time temperature equalization (tset)/set temperature (tset) > = 1.05 and <1.1, the adjusting frequency is 10HZ to 30HZ.

The closing degree of each vent switch is adjusted according to the ratio of the average temperature of the temperature sensor 4 in each regional space to the set temperature. When the temperature of the real-time region is equal (T current)/the set temperature (T set) > = 1.2, the opening angle of the channel is regulated to be between 70 and 90 degrees; when the temperature of the real-time region is equal (T current)/the set temperature (T set) > = 1.15 and <1.2, the opening angle of the channel is regulated to be 50-70 ℃; the temperature of the real-time region is equal (T current)/the set temperature (T set) > = 1.1 and <1.15, and the opening angle of the channel is regulated to be between 30 and 50 ℃; real-time temperature equalization (T current)/set temperature (T set) > = 1.05 and <1.1, and the opening angle of the adjusting channel is between 10 and 30 degrees. The opening angles of the air conveying pipelines in each area independently operate and do not interfere with each other.
When the air passes through the air outlet panel 2-5 through the air transmission pipeline, the frequency conversion host 1 adjusts the angles of blades in the honeycomb air outlets 2-1 according to the temperature of each area in the room transmitted in real time by the temperature sensor 4, and controls the air outlet quantity of each honeycomb air outlet 2-1, thereby implementing three frequency conversion.

In the heating process, according to the area divided by the two-stage machine panel 2-4, an electric heating plate is arranged under the floor, the electric heating plate is connected with a nearby temperature sensor 4, and the output power is continuously adjusted through the comparison of the temperature data transmitted by the temperature sensor 4 and the set temperature.

The cover is wide, and meanwhile, the roof plane space with more shapes can be adapted. Because the air outlet extends over the upper space, a plurality of cold air flows out along the air outlet at the same time and then quickly sinks due to the self weight of the air. The heating system is arranged at the lower layer of the floor of a room, an electric heating sheet is used as a heating source, the air in the special interlayer and the upper layer area of the floor is thermally expanded by heating, and the air is heated to flow and rise, and meanwhile, the temperature brought by the electric heating sheet enables the air to be expanded and rise continuously below the floor until the set room temperature requirement is reached.
