Abstract

The invention discloses an air conditioning system, and a method and device for measuring the weight of refrigerants of the air conditioning system. The method for measuring the weight of the refrigerants of the air conditioning system specifically comprises the steps that a compressor and a solenoid valve are controlled, and thus the refrigerants are all stored in an outdoor unit or an indoor unit and all discharged to the outdoor unit or the indoor unit; the weights of the outdoor unit or the indoor unit in the two states are measured and calculated correspondingly; and the weight of the refrigerants is obtained through the weight difference of the outdoor unit or the indoor unit in the two states. The weight of the refrigerants of the air conditioning system can be measured, and variousafter-sale problems related to the refrigerants are advantageously analyzed and solved.

Description

technical field

[0001] The invention relates to a split-type air-conditioning system, in particular to a method and device for measuring the weight of refrigerant in an air-conditioning system, and an air-conditioning system using the device. Background technique

[0002] The weight of the refrigerant in the air-conditioning system closely affects the use of the air-conditioner. Many after-sales problems in the air-conditioning industry are caused by abnormal refrigerants.

[0003] In the prior art, due to the complex installation structure of the air conditioning system, the calculation of the weight of the refrigerant in the industry is still at the stage of evaluation, that is, the engineer calculates the weight of the refrigerant based on his personal engineering experience and with reference to parameters such as system pressure, operating frequency, and degree of subcooling. Estimate whether the refrigerant is too much or too little. The estimation result obtained by t...

Embodiment Construction

[0022] Figure 1 to Figure 3 What is shown is a specific embodiment of the present invention, which mainly calculates the weight of the refrigerant by weighing the weight difference of the outdoor unit 100 of the air conditioning system.

[0023] Such as figure 1 As shown, the outdoor unit 100 of the air conditioning system of the present invention is provided with a first electromagnetic valve 1, a compressor 2, a heat exchanger 3, and a second electromagnetic valve 4 connected in sequence, and the first electromagnetic valve 1 is arranged on the pipe of the outdoor unit. At the entrance of the pipeline 5, the second electromagnetic valve 4 is arranged at the outlet of the pipeline 5 of the outdoor unit.

[0024] Such as figure 2 As shown, in this embodiment, the outdoor unit 100 is connected to the fixed base 9 through the support column 8, and the fixed base is fixed to the ground by bolts.

[0025] Such as image 3 As shown, there is a stress plate 10 attached to the ...
