Method and device for manufacturing air intake guide device

Abstract

The invention discloses a method for manufacturing an inlet air guiding device. The method includes the first step of enabling air deflectors to be rotatably connected with the front side of an evaporator of an indoor unit of an air conditioner, the second step of detecting the temperature Tn of heat exchange subregions of the evaporator, the third step of recording a current inclination angle to be an optimal inclination angle of the air deflectors when delta Tn=|Tn-T|<=delta T, adjusting the inclination angle between the heat exchange subregions and the corresponding air deflectors when delta Tn=|Tn-T|>delta T, and then going to the second step, wherein T is a preset temperature, delta Tn is the absolute value of a different value, and delta T is an allowable temperature difference, the fourth step of machining a frame and air guide blades of the inlet air guiding device, arranging the air guide blades on the frame according to the optimal inclination angle. According to the method, the manufactured inlet air guiding device is installed in the indoor unit of the air conditioner, and consequently the heat exchange efficiency of the evaporator and the energy efficiency of the air conditioner are improved. The invention further provides a device for manufacturing the inlet air guiding device.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a manufacturing method and a manufacturing device of an air inlet guide device for adjusting heat dissipation of an evaporator. Background technique [0002] During the cooling process of the air conditioner, there is a temperature difference in the outlet pipe temperature of each refrigerant flow path of the evaporator, so that there are superheated refrigerant flow path and liquid-laden refrigerant flow path in the refrigerant flow path of the evaporator, and the superheated refrigerant flow path The refrigerant in the tube absorbs heat and volatilizes into a gaseous state, and the heat-absorbing capacity of the refrigerant flow path is limited. The liquid refrigerant flow path means that the refrigerant in the tube has a liquid part, and the heat absorption is not complete. The refrigerating capacity of the superheated refrigerant flow path of the evaporator de...

Problems solved by technology

[0004] However, the adjustment of the refrigerant flow path of the evaporator is the link that consumes the most time in performance matching and the workload of machine modification is the largest. Moreover, due to the influence of the adjustment tooling, the adjustment effect of the external and internal liquid separation capillary is quite different. Adjusting the capillary once requires re-soldering

Usually limited by the shell space and capillary regulation capacity, there are several refrigerant flow paths with low or high outlet temperature, which will also reduce the heat transfer effect of the evaporator, resulting in high power consumption of the air conditioner. less energy efficient
