Lack of refrigerant and charging too much have that affect on the vending opportunity?

A, the vending machine is now disabled like and the reasons of the lack of refrigerant ( 1) Fault phenomenon: the vending machine machine refrigeration effect is poor, it's chilly air outlet, and with manifold pressure gauge inspection found that the high side, low voltage side pressure were low ( In the compressor speed of 2000 r/min, the environment temperature is about 35 ℃, low pressure table index is below 1 kg/cm2, high pressure table index less than 10 kg/cm2) Visible bubble flow, from sight in the mirror at the same time. ( 2) The cause of the problem: there is no cold vending mechanism system refrigerant leak, caused by lack of refrigerant. ( 3) Methods: 1) Using electronic leak detector detect leak and for repair or replacement parts. 2) If not only a moderate amount of added refrigerant replacement components; If the replacement parts, should be adding suitable amount of frozen oil, according to the requirement and foot refrigerant on the system after the vacuum. Second, the vending machine refrigerant charging too much fault phenomenon and processing methods ( 1) Fault phenomenon: the vending machine machine refrigeration effect is poor, with manifold pressure gauge inspection found that the high side, low voltage side pressure is too high ( Around the compressor speed of 2000 r/min, the environment temperature of 35 ℃, the high pressure gauge pressure is about 19 kg/cm2, the low pressure gauge pressure of 2. 3 kg/cm2, and depending on the fluid in the mirror to see bubbles flow. ( 2) The cause of the problem: too much filling refrigerant in the refrigeration system, the refrigeration capacity cannot give full play to, lead to the refrigeration effect is poor. ( 3) Processing method: in the vending mechanism of cold system connected to the manifold pressure gauge, slowly unscrew the manifold pressure gauge manual valve on the low voltage side, the refrigerant discharge (slowly Not from the high side, because from the high side put refrigerant will take a lot of frozen oil) Until the high and low side pressure is normal, as well as from visual liquid refrigerant flow clear can be seen in the mirror, and occasionally there are air bubbles. The vending machine China's large unmanned vending machine manufacturers, to provide cost-effective, full series of vending machines, meet the demand of customer personalization, create new vending machine products. Adult supplies the vending machine sales of $9999.
