The invention provides a control method of an air conditioning unit and the air conditioning unit. The air conditioning unit is provided with a plurality of air supply outlets, a cabin is divided into a plurality of areas from top to bottom, and each area is at least communicated with one air supply outlet. Adjusting the target temperature or the target humidity of the cabin in the middle area, and performing compensation by taking the target temperature or the target humidity of the middle area as a reference to set the target temperature or the target humidity of other areas; and controlling the air valve opening degree of the air supply outlet of each area to enable the detected temperature of each area to be close to or equal to the target temperature. According to the invention, the cabin is partitioned, and air supply control is carried out on each region, so that the temperature control in the cabin is more accurate. And the temperature and humidity control efficiency of the unit is improved by correcting the temperature of the air outlet side of the condenser and the humidity of the air outlet side of the evaporator.

The invention relates to the technical field of vegetable cultivation, and discloses a vegetable full-coverage ecological efficient cultivation technology which comprises the following steps: step 1, selecting and designing a functional composite mulching film which has the functions of temperature and humidity regulation, pest control, accurate nutrient release and soil protection, and the design of the mulching film comprises a multi-layer structure, each layer has different functions; and step 2, performing plastic film mulching: laying the functional composite plastic film on a vegetable planting area to cover the whole soil surface so as to form a full-coverage cultivation environment. Through optimization of a cultivation environment and accurate nutrient management, the growth efficiency and yield of crops are remarkably improved, a full-coverage cultivation technology and an intelligent fertilization system are combined, so that the crops can obtain appropriate moisture, illumination, nutrients and other elements in different growth stages, and thus healthy growth and disease resistance of the crops are enhanced; the overall quality and the market competitiveness of the vegetables are improved.

The invention relates to a spinning method based on a spinning microenvironment system, in the spinning process, constant-temperature and constant-humidity air flow is conveyed to each spinning unit through a variable cross-section air supply pipeline, and the air flow quantity and the air flow speed conveyed to each spinning unit are equal; all the spinning units are independently connected with the variable-cross-section air supply pipeline through branch pipes, the cross sectional areas of all the branch pipes are equal and equal to the cross sectional area of the output end of the variable-cross-section air supply pipeline, all the branch pipes are distributed in the length direction of the variable-cross-section air supply pipeline at equal intervals, and the interval is the spindle distance L of the spinning units; the section of the variable-section air supply pipeline is round, square or rectangular, and the cross section area, length or width of the variable-section air supply pipeline from the airflow input end to the airflow output end is evenly decreased. Each spinning unit is provided with a unit fairing composed of a fairing body and a flow guide plate, and the flow guide plate is a perforated plate provided with uniform through holes in the thickness direction. The microenvironment temperature and humidity of the drafting area of the spinning unit are stable, and the yarn forming quality and the production efficiency are effectively improved.

The application provides a control method of an air conditioning unit and the air conditioning unit. The air conditioning unit has multiple air outlets. A cabin is divided into multiple areas from top to bottom. Each area is connected with at least one air outlet. The control method comprises the following steps: when the temperature or humidity of the cabin does not meet the use requirement, the target temperature or target humidity of the middle area of the cabin is adjusted, and the target temperature or target humidity of other areas is set by compensation based on the target temperature or target humidity of the middle area; and the air valve opening degree of each area is controlled so that the temperature detected by each area is close to or equal to the target temperature. The cabin is divided into multiple areas, and air supply control is performed on each area, so that the temperature control in the cabin is more accurate. The temperature on the air outlet side of the condenser and the humidity on the air outlet side of the evaporator are corrected, and the temperature and humidity control efficiency of the unit is improved.
