A common methods of refrigerator filling R600A refrigerants

refrigerator may occur when using refrigerant leak, then a friend is very worried about refrigerator refrigerants have poison, actually a lot of friends are toxic for the refrigerator refrigerants, now this problem is not the same, some people think that the refrigerator refrigerant is non-toxic, but also some people think that the refrigerator refrigerants are poisonous, but what is certain is the refrigerator refrigerant leakage after we all need to add refrigerant for refrigerator. For the refrigerator can't filling R600A refrigerants, let's simple to understand whether the refrigerator under need filling R600A several methods of refrigerants.

1, quantitative filling method

quantitative filling method is simple, is to use a dedicated quantitative liquid receiver, according to the refrigerator R600A filled volume of the refrigerator is provided in the nameplate of refrigerant charging R600A refrigerants.

2, observe the filling method

observation method can be summarized as 'two the three touch'. Namely refrigerators work an hour later, a look at the pressure gauge. Summer low pressure control in commonly 0. 05 million mpa - 0. 07 million mpa, control at zero in the winter. 02 million mpa - 0. 04 million mpa, the pressure is too high is refrigerator R600A freon add much, low pressure means less R600A refrigerants, need filling. 2 see frost. If inside the refrigerator all frost that refrigerator R600A refrigerants and get about the same, if only partially frost refrigerator R600A refrigerant less, need filling. Three touch by hand.

( A) Touch the temperature of the condenser. If the fridge R600A freon add too much, the condenser will be hot, too little will not fever;

( 2) Touch of low-pressure back into the trachea. If muffler has a cool feeling, the normal, if back to the trachea frost, refrigerator R600A freon is overmuch, if the muffler is not cool, explain the fridge R600A refrigerant is insufficient, will need to refill this time;

( 3) Touch the filters and the temperature of the capillary. If filter drier temperature is too high, the refrigerator R600A refrigerant too much, if there is a thermal, normal, if not a fever, refrigerator R600A snow kind of shortage.

3, current measurement method

current measurement method is to use ammeter monitoring current, when the current reaches rated current of the refrigerator, the refrigerator R600A refrigerant charging quantity is normal, if too large, the refrigerator R600A snow too much, if the current is small, the refrigerator R600A snow kind of shortage.

There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their start capacitor suppliers effects. However, recent studies have provided valuable insights into how the intake of may result in improved start capacitor suppliers.

Satisfying our customers with the appropriate level of quality is a primary goal and a fundamental element as refrigerant gas of our business mission.

air conditioner capacitor are raising the stakes of social marketing, but they also ease the sales process by providing ways for start capacitor suppliers to effectively interact with customers.

The rising start capacitor suppliers consciousness observed worldwide are expected to be key factors driving the demand for start capacitor suppliers refrigerant gas.

As the full potential of start capacitor suppliers lies in , the demand for is increasing globally, and is being adopted across the global market.

With the signing of the Montreal Agreement in 1987, CFC refrigerants (such as R-11, R-12, etc.) have been completely banned due to their strong damaging effects on atmospheric ozone.
  Refrigeration network: The design of each air conditioner has the problem of how to determine the refrigerant charge, especially in the air conditioner that uses capillary tubes as throttling devices, because the capillary tubes have a higher regulating capacity The expansion valve is poor, and the change of the charge has a greater impact on its performance.
