Description

Technical Field

[0001] The utility model relates to the technical field of indoor units, and specifically relates to a fixing component for an indoor unit. Background Technique

[0002] The multi-connected system of air conditioners implements a "one-drags-many" mode. During the heating operation, because the capacities of the indoor units are different, each indoor unit independently controls the opening degree of the indoor unit EEV;

[0003] If the capacities of each indoor unit are close, there will be no great impact. If there is a large difference in the capacities between indoor units, and combined with the differences in the installation environment and actual use conditions, the uneven distribution of the refrigeration and heat flow will occur. Eventually, the result is that the large-capacity indoor unit has good heating effect, high air outlet temperature, and good user experience, while the small-capacity indoor unit has poor heating effect, low air outlet temperature, and poor user experience. And because the installation position of the indoor unit is fixed, although the air outlet of the indoor unit can be adjusted, however, the adjustment direction of the indoor unit is too limited, so that the air blown out from the air outlet blows to too few positions, affecting the refrigeration and heating effects of the indoor unit. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing component for an indoor unit to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixing component for an indoor unit, including:

[0006] A fixing rod, on the surface of which an adjustment groove is provided;

[0007] A front convex block, on the surface of which a fastening bolt is screwed. On the surface of the fixing rod, a clamping groove is provided, and an active clamping block is arranged inside the clamping groove; and

[0008] A fixing bracket, arranged on the surface of the fixing rod;

[0009] Fixing brackets are fixed at both ends of the fixing rod, the fixing brackets are fixed on the wall, multiple groups of adjustment grooves are provided on the surface of the fixing rod, and multiple groups of clamping grooves are provided on the surface of the fixing rod;

[0010] The adjustment groove and the clamping groove are connected. A positioning plate is inserted into the adjustment groove, the positioning plate can move in the adjustment groove, the positioning plate is connected to an adjustment rod, and an indoor unit is fixed on the surface of the adjustment rod.

[0011] Preferably, the adjustment rod moves along with the positioning plate. A positioning groove is provided on the surface of the adjustment rod, and a rear convex block and a front convex block are fixed on the surface of the fixing rod.

[0012] Preferably, fastening bolts are screwed on the surfaces of the rear convex block and the front convex block. An active clamping block is arranged at the end of the fastening bolt. The cross-section of the end of the fastening bolt is T-shaped, and the end of the fastening bolt is inserted into the interior of the active clamping block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The present utility model can solve the problem of large temperature differences at the air outlets of indoor units caused by many reasons such as installation environment, large height differences of indoor units, large differences in indoor unit capacities, and uneven distribution ratios of manifold pipes. Through actual verification, it has a relatively good effect. On the premise of ensuring small differences, the capacities of each indoor unit can finally be restored to the rated values, achieving a very good effect. The indoor unit is fixed on the surface of the adjusting rod, and the positioning plate can move in the adjusting groove. When the fastening bolt is screwed, the active clamping block abuts against the surface of the positioning plate to fix the position of the indoor unit. When the active clamping block is retracted into the front convex block, the positioning plate can move in the clamping groove. When the positioning plate moves to the position of the next set of adjusting grooves, the position of the positioning plate can be adjusted, and thus the position of the indoor unit can be adjusted, facilitating the adjustment of the position of the indoor unit.

[0025] An indoor unit capacity balancing method includes the following steps:

[0026] Step 1: Start, the indoor unit operates in the heating mode for 10 minutes; other conditions equivalent to heating such as defrosting end, warm room oil return end for 10 minutes;

[0027] Step 2: Control. After the indoor unit starts heating operation for 10 minutes, measure the TRI2 temperature of all temperature-controlled on indoor units, and compare it. The off indoor unit and the temperature-controlled off indoor unit do not participate. After the data acquisition is completed, the indoor unit with the minimum temperature is TRI2 / min, and the indoor unit with the maximum temperature is TRI2 / max. At the same time as the data acquisition is completed, start the next 10-minute cycle timing. For each temperature-controlled on indoor unit, if there is ≥1 indoor unit with TRI2 - TRI2 / min > 10°C, then enter the capacity correction and balance mode.

After operating for 10 minutes, if TRI2 / max - TRI2 / min ≤ 10°C of the indoor units in the middle still holds, then open the EEV of all temperature-controlled on indoor units, and change Pls to the current value × 1.1; at this time, the capacity correction and balance mode exits, and each temperature-controlled on indoor unit performs normal control. If TRI2 / max - TRI2 / min ≤ 10°C of the indoor units in the middle no longer holds, then repeat the content in Step 2.
