R600a Properties

R600a product nature

1. Vapor pressure

The evaporation of R600a at -25°C is 55% of R-134a and 45% of R-12, and its normal boiling point is 15K and 18K higher than R-134a and R-12, respectively. This causes the operating pressure to be much lower than other refrigerants used in the past, so that the evaporator of the household refrigerator can be operated at a pressure lower than the atmospheric pressure.

2. Refrigeration capacity

The unit refrigeration capacity of R600a is 50% of R12 and 55% of R-134a, so R600a requires compressor stroke displacement twice as large as R12.

3. Charge

According to the mass, the filling volume of R600a is about 45% of R-134a and 40% of R-12. Experience has shown that the refrigeration system is very sensitive to the requirement of refrigerant filling amount and must be filled strictly according to the required accuracy. In a small refrigerator, only 20g needs to be filled, and the accuracy is within 1g. In household refrigerators or small appliances, the maximum charge is 150g. Purity of R600a The purity of R600a refrigerant is related to its chemical and thermal stability, which directly affects the performance of the refrigeration system and the service life of the compressor.

At present, R600a (isobutane) with a purity of 95% on the market has high water content and high sulfur content and cannot be used in refrigeration equipment. The purity of R600a refrigerant is related to its chemical and thermal stability, which directly affects the performance of the refrigeration system and the service life of the compressor. The purity of R600a refrigerant must be above 99.5% before it can be used in refrigeration equipment.

Storage and Transportation

(1) R600a storage

R600a refrigerant cylinders are pressurized containers. They should be stored away from fire, heat sources, and direct sunlight. They are usually stored in a cool, dry and ventilated warehouse;

R600a is stored separately from oxidizers, combustibles or combustibles, and aluminum. Remember to store them together.

Storage area should be equipped with leakage emergency treatment equipment.

Pay attention to the product name and the date of acceptance during acceptance, and use advanced warehouses first;

(2) R600a transportation

When using steel cylinders, you must wear the safety helmets on the cylinders. Place the steel cylinder horizontally with the mouth of the cylinder facing the same direction and do not store it crosswise

When transporting, load and unload lightly to prevent damage to accessories such as cylinders and valves.

In summer, it should be transported in the morning and evening to prevent sun exposure and away from heat sources;

It is forbidden to drop off during railway and road transportation;

Do not mix with oxidants, combustibles or combustibles, active metals, etc.;

Workshop and Shipment Glance

The advantages of typical hydrocarbon refrigerants such as isobutane (R600a) just overcome the shortcomings of R134a refrigerant. 

The excellent thermophysical properties of R600a determine that the refrigerant has higher energy efficiency and compressor efficiency 

than CFCS and HFCS. (COP value) and the refrigerator's overall cooling efficiency (power consumption index) are higher than R134a. 

Due to the advantages of energy saving and environmental pollution, Germany first succeeded in using hydrocarbons as refrigerants in

 refrigerators. With the maturity of process and technology, R600a refrigerant has also been widely used in China's refrigeration industry.
