Introduction to the analysis of ice machine refrigerant

The ice maker is a refrigeration mechanical device that generates water by cooling the refrigerant from the refrigerant of the refrigeration system through the evaporator. The refrigeration system uses a water carrier to produce ice after passing through a certain device in an energized state. According to the principle of the evaporator and the production method, the shape of the generated ice cubes is also different; people generally divide the ice machine into ice ice machine, ice machine, ice machine, tube ice machine, shell ice machine, etc. Wait.

The refrigerants of the ice machine mainly include: R22, R134a, R404a. Now Shanghai Bayu introduces the characteristics of various refrigerants.

R22: Fluorine-containing refrigerant has long been monopolized in the market. However, it pollutes the environment and destroys the ozone layer within 15km-25km of the earth, so that more solar ultraviolet light can radiate to the earth and harm human health.

R134a: A new generation of refrigerants containing tetrafluoroethane with the following main features :

1. R 134a does not contain chlorine atoms and does not damage the atmospheric ozone layer;

2. R 134a has good safety performance (non-flammable, non-explosive, non-toxic, non-irritating and non-corrosive);

3. The heat transfer performance of R 134a is relatively close, so the modification of the refrigeration system is relatively easy.

4. R 134a has better heat transfer performance than R 22 , so the amount of refrigerant can be greatly reduced.

R404a: is a fluorine-free non-azeotropic refrigerant mixture. It is a colorless gas at normal temperature and a colorless transparent liquid under its own pressure. It is also an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer. Has the following characteristics:

1 Refrigerant R404A composition: HCFC-125 (44%) + HFC-134a (4%) + HFC-143a (52%)

2 Refrigerant R404A is an industry standard HFC that replaces R-502 and is used in new commercial refrigeration equipment worldwide.

3 Refrigerant R404A is suitable for new or low-temperature equipment or newer equipment, the closest to the operation of R-502, even up to 15oF (-9.4oC) or colder.

4 has the characteristics of clean, low toxicity, non-combustible, good cooling effect.
