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 piece are arranged in each divided area. Wherein, the region blocking principle: firstly, drawing a planar two-dimensional pixel map according to the density of indoor objects (the color block at the place with large density is deep, and the color with small density is light), taking n points (about one point per 15 square meters) on the map based on the average point of the actual indoor area, then carrying out region growing and blocking principle on the n points (the unmarked pixel points near the search points are merged into the segmentation region if the difference value of the pixel points is within the specified threshold value), roughly segmenting n regions by the method, and then carrying out detail optimization (the edge line of the boundary line is subjected to edge angle) on the shapes of the n regions to achieve that the area of each region is approximately 15 square or so. Each area is provided with 15-25 honeycomb type air outlets 2-1 approximately, and gaps among the air outlets are spliced by honeycomb type wood boards with equal size. The placement of the underground electric heating pieces is also in accordance with the blocking principle, and each electric heating piece corresponds to the air opening at the upper honeycomb one by one.
When the current temperature control mode is selected as the refrigeration mode, acquiring first temperatures of all the temperature sensors 4 in each area; and controlling the air output of the honeycomb type air outlet 2-1 and the air output angle of the fan blades of the air outlet according to the first temperature.
In the refrigeration process, after the frequency conversion host 1 operates, the temperature sensors 4 on the peripheral walls input collected temperature data into the host, the heat insulation layer partition plates 2-3 and the air outlet panels 2-5, and the frequency conversion host 1 carries out primary frequency conversion according to indoor uniform temperature and adjusts output power. Wherein, in the frequency conversion process, taking a frequency conversion host machine of 10 HZ-90 HZ as an example, during refrigeration: when the real-time temperature equalization (Tnow)/set temperature (Tset) > <1.2, the adjusting frequency is between 70HZ and 90 HZ; when the real-time temperature equalization (Tect)/set temperature (Tet) > <1.15 and <1.2, the adjusting frequency is 50 HZ-70 HZ; the real-time temperature equalization (Tect)/set temperature (Tet) > <1.1 and <1.15, and the adjusting frequency is 30 HZ-50 HZ; the real-time average temperature (Tnow)/set temperature (Tset) > is 1.05 and less than 1.1, and the adjusting frequency is 10 HZ-30 HZ. During heating: the algorithm is the same as that in the refrigeration process, heating set temperature (Tset)/real-time temperature equalization (Tnow) is brought into the algorithm for realizing temperature control based on the indoor subareas, namely: when the real-time temperature equalization (Tect)/set temperature (Tet) > (1.2), the adjusting frequency is between 70HZ and 90 HZ; when the real-time temperature equalization (Tect)/set temperature (Tet) > <1.15 and <1.2, the adjusting frequency is 50 HZ-70 HZ; the real-time temperature equalization (Tect)/set temperature (Tet) > <1.1 and <1.15, and the adjusting frequency is 30 HZ-50 HZ; the real-time temperature equalization (tcurrent)/set temperature (tcet) > < 1.05 and <1.1, and the adjustment frequency is 10HZ to 30 HZ.
When the air flow output after the frequency conversion of the main machine enters the areas between the heat-insulating layer partition plates 2-3 and the air outlet panels 2-5, the frequency conversion main machine 1 adjusts the closing degree of each air vent switch in the heat-insulating layer partition plates 2-3 according to the temperature of each area in a room transmitted by the temperature sensor 4 in real time, and the air flow flows along the air transmission pipeline to realize secondary frequency conversion. The closing degree of each air vent switch is adjusted according to the ratio of the average temperature of the temperature sensor 4 in each area space to the set temperature. When the real-time zone temperature equalization (Tecurrent)/set temperature (Teset) > -1.2, adjusting the opening angle of the channel to be 70-90 degrees; when the real-time zone temperature equalization (Tect)/set temperature (Tet) > <1.15 and <1.2, adjusting the opening angle of the channel to be between 50 and 70 degrees; the real-time area temperature equalization (Tect)/set temperature (Tet) > <1.1 and <1.15, and the opening angle of the channel is adjusted to be between 30 and 50 degrees; the real-time temperature equalization (Tnow)/set temperature (Tset) > < 1.05 and <1.1, and the opening angle of the channel is adjusted to be between 10 and 30 degrees. The opening angle of the air conveying pipeline in each area operates independently and does not interfere with each other.
When gas passes through the air outlet panel 2-5 through the air delivery pipeline, the frequency conversion host 1 adjusts the angle of the blades in the honeycomb air outlet 2-1 according to the temperature of each area in the room transmitted by the temperature sensor 4 in real time, and controls the air output of each honeycomb air outlet 2-1, so that three-time frequency conversion is implemented.
When the current temperature control mode is selected as the heating mode, acquiring second temperatures of all the temperature sensors 4 in each area; and controlling the temperature of the electric heating piece according to the first temperature control. In the heating process, according to the areas divided by the panels 2-4 of the secondary unit, the electric heating sheets are installed under the floor and connected with the temperature sensors 4 nearby, and the output power is continuously adjusted by comparing the temperature data transmitted by the temperature sensors 4 with the set temperature.
The invention is divided into a refrigerating part and a heating part, a refrigerating system 2 is arranged on the roof, and a full-coverage structure-a honeycomb structure is adopted. The covering surface is wide, and simultaneously, the roof plane space with more shapes can be adapted. Because the air outlet is distributed in the upper space, a plurality of strands of cold air are simultaneously emitted along the air outlet and then sink rapidly due to the self weight of the air, and due to the unique regional block design, the refrigeration universalization and the aging are realized. The heating system is arranged on the lower floor of a room, the electric heating sheet is used as a heating source, air on the special interlayer and the upper floor is thermally expanded through heating, and when hot air flows and rises by self, the temperature brought by the electric heating sheet enables the hot air below to continuously expand and rise until the requirement of the set room temperature is met. High efficiency is achieved while ensuring human body comfort. The refrigerating system 2 is arranged above the heating system 3, and the air power principle is fully applied below the heating system, so that the time for reaching the set temperature is greatly reduced.
