Problems solved by technology

This situation is mainly caused by the water medium in the main pipe. The flow rate is too fast in the process of entering the plate heat exchanger, and most of the water is accumulated in the interior of the above-mentioned plate heat exchanger, resulting in the closer to the water inlet The smaller the partial water flow, the unbalanced water flow between each plate will inevitably lead to insufficient heat exchange between the water system and the fluorine system of the plate heat exchanger
Therefore, the operation of the entire air conditioning system is out of balance, the capacity of the unit cannot be fully utilized, and even the unit cannot operate normally or the parts are damaged; this situation is especially obvious when the unit is operating under variable and severe conditions.
The existence of the above problems has not been effectively solved so far.

Embodiment 1

[0032] A method of fluid distribution, which consists of the following steps. The air-conditioning unit uses a dual-system plate heat exchanger (commonly known as a back-to-back plate heat exchanger). During operation, it is found that there is a pressure imbalance on the fluorine side of the two systems, and the low-pressure pressure deviation of the two systems Larger, among which the system with low pressure (system 1) is seriously unbalanced. After a period of operation, low-pressure trips occur, which is most obvious when the water temperature and ambient temperature are lowered; after inspection, it is found that the distribution of the water system is seriously unbalanced. Among them, the water flow rate of system 1 is obviously smaller than that of system 1, which causes the pressure on the low pressure side of system 1 to be too low or even trip at low pressure. By adding a water flow distribution device in the plate heat exchanger water system, the water flow disturba...

Abstract

The invention relates to a distributor for adjusting the fluxes at different parts of one tube, used in plate heat exchanger of air conditioner. The distributor comprises tubular main body 1 and through hole 2 arranged on side wall of main body 1, wherein, one end of main body is sealed and another end is fluid inlet. The distributor is arranged on the fluid main tube at the combination of main tube and branch tubes. The invention can divert fluid via the demands of branches, while the invention also provides relative application method.

Description

【Technical field】 [0001] The invention belongs to the field of fluid flow distribution, in particular to a distribution device used in an air conditioner plate heat exchanger for adjusting the flow of fluid at different parts in the same pipeline. 【Background technique】 [0002] At present, when the fluid flows in the pipeline, it is often necessary to distribute the flow according to the demand, especially when the flow is distributed between the main pipeline and the branch pipeline, there is often an unbalanced flow distribution, which makes the system unpredictable. Normal and stable work. A more prominent example is the uneven flow distribution of the plate heat exchanger, especially the water system of the larger and thicker plate heat exchanger. This situation is mainly caused by the water medium in the main pipe. The flow rate is too fast in the process of entering the plate heat exchanger, and most of the water is accumulated in the interior of the above-mentioned ...
