Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0025] Embodiments of the present invention provide a finned evaporator, such as figure 1 As shown, the finned evaporator 2 includes: a plurality of liquid distribution branches, each of which is provided with a refrigerant flow regulating valve and a temperature sensor; the connection between the finned evaporator 2 and the compressor 1 A temperature sensor 7 is arranged on the pipeline.

[0026] Further, the whole system can also be as figure 1 As shown, it includes fan 3 , throttling device 4 , filter 5 and condenser 6 .

[0027] It is worth noting that the flow control valve does not hav...

Abstract

The invention provides a finned evaporator and a liquid distribution control method and device thereof. The finned evaporator comprises a plurality of liquid distribution branches, and a refrigerant flow adjusting valve and a temperature sensor are arranged on each liquid distribution branch; and a temperature sensor is arranged on a connecting pipeline of the finned evaporator and a compressor. The technical problem that liquid distribution of an existing finned evaporation heat exchanger is uneven is solved, the heat exchange performance loss of the heat exchanger due to uneven liquid distribution is avoided, and air suction with liquid of the compressor can be avoided under the rated load or the low load.

Description

technical field [0001] The invention relates to the technical field of air conditioning control, in particular to a finned evaporator and its liquid separation control method and device. Background technique [0002] The scroll compressor belongs to the volumetric compressor, which increases the pressure of the compressed gas by compressing the volume of the gas. If the gas inhaled by the scroll compressor is liquid-carrying, due to the incompressibility of the liquid, long-term operation is easy to damage the compressor, and at the same time affect the oil return of the compressor itself. [0003] The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed "liquid" passes through the evaporator to exchange heat with the outside air, and the "gas" absorbs heat to achieve the effect of refrigeration. The common finned evaporator is to separate the liquid through the liquid separation head. However, due to the influence...
