1, q: r410a refrigerant charging is the need to pay attention to?
A: don't with other refrigerant R410A refrigerant, refrigeration oil.
Special tools are mainly in the aspect of after-sales service, and the use of other refrigerant air conditioning, don't mix.
Due to the pressure of R410A is higher, so the piping, tools for the special.
Because of the different and before using other refrigerant R410A refrigerant vulnerable to moisture, oxidation layer, grease, etc. The influence of impurity content, so that full attention should be paid during operation, use clean pipe, prevent moisture, etc.
In addition, also note that the cannot use already used in the piping.
When installing the construction must make the pledge that we shall use the new piping.
In the process of welding must maintain in tube side flow nitrogen, one side welding.
From the perspective of protection of atmospheric environment, you need to use the vacuum pump to vacuum the compressor.
Because is a kind of approximate azeotropic mixture refrigerant R410A, when add refrigerant, using liquid way add.
2, q: r410a refrigerant is harmful to people?
A: 410 a refrigerant mixed refrigerant is a colorless, odorless, non-toxic.
But long-term inhaled into cause anoxic discomfort or even suffocation.
3, ask: how many ㎏ r410a refrigerant bottle?
Answer: at present in cool packaging specifications are: not to reuse the cylinder.
3 kg, repeated use cylinder 400 l / 800 l / 926 l / 1000 l, 18 t tanker.
4, q: r410a refrigerant how many money?
Answer: the price of R410a is probably twice that of R22 bottled 10 kg in 400 yuan, bottles and 22.
7 kg of R22 price is 400 a can also.
Prices are for reference only, without the brand, the price of different packaging, factory will have the difference.
5, ask: what brand of refrigerant R410A is better?
Answer: import do best is dupont refrigerant, do the best domestic refrigerants, other belong to medium products, gold is cold, and three love rich, dongyue, cool lippo, also belong to a good brand.
6, q: add refrigerant R410a air conditioning?
How much to add?
A: add 410 a refrigerant basically has the following steps: when a.
Ready to air conditioning sign corresponding R410a refrigerant, double gaps watch, thermometer, pressure gauge set current card table, etc.
b。
A head connected hose R410 refrigerant steel cylinder valves, a double toki table in the middle connector.
Outdoor parts in low voltage side hose tubes on needle valve, valve should be opened before fluorine bottle and table a small discharge air valve switch, then tighten.
c。
Open air conditioning, set 'cooling' function, low temperature setting (
Winter, should be set minimum, or even indoor machine of temperature sensing head heating)
。
After waiting for compressor rotation, open R410 refrigerant cylinder valves, and the horse fluorine bottle, then open the valve round table, the 410 a refrigerant has quickly into the thick copper tube.
A few seconds,
No more than ten seconds)
Close the table after valve, after waiting for air conditioning for a few minutes, and repeat.
d。
Touch the thick copper pipe, outdoor tubes should feel very cold, and the presents of condensed water and pipe temperature should be between 5 to 15 degrees, add R410 refrigerant (
Summer low pressure does not exceed 0.
6MPa)
。
7, q: several mixed refrigerant R410A is?
Answer: R410A, is a kind of mixed refrigerant, it is by R32 (
Methylene fluoride)
And R125 (
Five fluorine ethane)
Consisting of a mixture, its advantage is that can be used according to the specific requirements, for a variety of properties, such as flammability, capacity, exhaust gas temperature and efficiency into consideration, tailored to synthesize a kind of refrigerant.
R410A appearance not cloudy, colorless, volatile, boiling point -
51.
6 ℃, freezing point -
155℃。
