How to fill the ice cream machine with refrigerant, and how often does the ice cream machine add ref

Probably, it depends on how much refrigerant is added. If the refrigerant is filled too much, it will cause the ice cream machine to intermittently have too high exhaust pressure or too high exhaust temperature during operation and stop refrigeration, resulting in poor cooling effect of the ice cream machine.

The refrigerant filling should be carried out after vacuuming, and there are four filling methods: weighing filling method, gauge pressure filling method, empirical filling method and quantitative filling method.

1) Weighing and filling method.

The weighing and filling method is a filling method that uses electronic scales to weigh the scale. When operating, put the refrigerant cylinder on the tray of the electronic scale, connect the filter drier, the liquid filling pipe and the three-way valve, put the air in the connecting pipe, weigh the weight, and then subtract the amount of refrigerant that needs to be charged, write down the remaining weight, and then slowly fill the refrigerant until the scale matches the remaining quantity.

2) Gauge pressure filling method.

The gauge injection method uses the low-pressure suction pressure of the refrigeration circulation system to determine the amount of charge. When operating, the refrigerant cylinder is connected with the filter drier, the connecting pipe, the three-way valve and the vacuum pressure gauge can be charged, the indication value of the pressure gauge is observed when filling, when the pressure is expressed, the three-way valve is closed, let the compressor run, when the pressure gauge drops to 0, then open the three-way valve, adjust the pressure, and then let the compressor run for a period of time until the suction pressure is stable and unchanged.

3) Empirical annotation method.

The empirical filling method is a method of determining the amount of filling according to the cooling situation of the air conditioner. The connection method is the same as the gauge pressure filling method, when the refrigerant is filled to the vacuum pressure gauge value, close the three-way valve, and run for 30 minutes until the compressor suction pipe is condensed.

4) Quantitative dosing method.

The timing filling method is a method that uses the filler to fill according to the rated filling volume of the air conditioner. Select the appropriate scale of the graduated cylinder, open the corresponding valve, let the refrigerant flow into the graduated cylinder, when the refrigerant reaches the selected scale, open the filler valve, so that the refrigerant in the graduated cylinder flows into the refrigeration system. This method has an accurate filling volume and is suitable for on-site maintenance.

Summary. Hello, if your ice cream machine cools well, then you don't need to add refrigerant.

After using it for a period of time (about one or two months), if you find that the refrigeration effect is not very good, you can find a master to help you see if there is a lack of refrigerant, and if so, then add refrigerant.

How often does the ice cream maker need to add refrigerant.

Hello, if you take the ice cream mechanism to make a good result, then you don't need to add refrigerant. After using it for a period of time (about one or two months), if you find that the refrigeration effect is not very good, you can find a master Hu Pai Fu to help you see if there is a lack of refrigerant, and if so, then add refrigerant.

How to adjust the molding ratio of Guangkun ice cream shower?

How to adjust it normally.

1. Ice cream is too hard to hold 1The hardness is adjusted too much (the hardness is adjusted to the normal range) 2Too little slurry in the refrigeration cylinder (add enough slurry to the pre-cooling cylinder) 3

The milk quality of the slurry and the sugar content are too low (adjust the proportion of ingredients in each slurry) 4Liquefier feed elimination hole destruction, feed pipe blocked (dredge liquefier feed hole, feed pipe) 2, ice cream is too soft 1The abnormal power supply voltage causes line protection (the voltage exceeds the normal range, at this time, the machine should be stopped to find out the cause) 2

The hardness set is too small (the hardness stop is adjusted to the normal range).

How to display the alarm for half a cylinder.

Guangshen ice cream machine is a relatively mature brand in China, and its performance and operation are not bad. If there is a material also shows a lack of material alarm, first of all, please check whether the ice cream slurry is sufficient, check Changqing Qi to see which slurry cylinder alarm is corresponding, if the basic operation is not bad, there is no problem with the ant will also call the police, it is recommended to contact the after-sales service, let the professionals help you check it is more appropriate.

How much after-sales ** can't get through.

When you buy it, Guangkun left you an after-sales **, and if you can't get through, it may be busy, so you wait and then call over.

The nameplate on the ice cream machine is usually marked, and the parameters on the nameplate can be added with refrigerant. The amount of refrigerant added to each ice cream machine is not necessarily the same, depending on whether the compressor model is the same.

As shown in the figure below, the refrigerant model marked on the nameplate of the machine is R404A, and the addition amount is 1kg.
