Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] A method for calibrating refrigerant filling equipment of the present invention, the calibrating system it adopts is as follows: figure 1 As shown, it specifically includes the following steps:

[0044] a. Set the refrigerant charging amount of the refrigerant charging machine according to the design standard of refrigerant charging, for example, the refrigerant charging amount of a general car is about 460 grams;

[0045] b. Connect the charging head of the refrigerant charging machine to the connection interface on the air inlet of a calibration gas tank 1. The connection interface adopts a quick connector that can be quickly connected to the charging head, and open the air inlet of the calibration gas tank. Valve, the valve can adopt existing structures such as ball valves, and a vacuum sensor for detecting the vacuum degree of the c...

Abstract

The invention discloses a calibration method of coolant filling equipment. Filling amount of a filling machine is set first; a calibrated gas tank is filled with a set amount of coolant; the coolant turns into gaseous coolant in the calibrated gas tank; a flowmeter and a storage tank are connected to the calibrated gas tank; the storage tank is evacuated through a vacuum pump; accordingly, the gaseous coolant in the calibrated gas tank flows into the storage tank by the aid of pressure difference; the flowmeter can record corresponding flow of the coolant so as to calibrate the filling machine; the gaseous coolant in the storage tank is compressed and condensed into liquid coolant by a coolant unit, the liquid coolant is stored in a liquid storage tank to provide convenience of recovery. The calibration method has the advantages that the calibration coolant can be recovered to eliminate atmospheric pollution, and the whole calibration process is highly automated.

Description

[0001] technical field [0002] The invention relates to a refrigerant filling technology for a vehicle-mounted air conditioner, in particular to a calibration method for refrigerant filling equipment. [0003] Background technique [0004] The amount of refrigerant filling has a crucial effect on the cooling effect of the car air conditioner. Too little refrigerant filling will reduce the efficiency of the evaporator, thereby affecting the cooling effect of the car air conditioner; The high-pressure refrigerant cannot be completely evaporated. When the liquid refrigerant enters the compressor, the load on the compressor will be greatly increased, and the compressor will be seriously damaged. For this reason, automobile manufacturers need to accurately calibrate the refrigerant filling equipment of the vehicle, so that it can always be kept in a qualified working state, so as to accurately fill the vehicle air conditioner with refrigerant. [0005] At present, the common m...
