Refrigerants are also called refrigeration working fluids, commonly known as refrigerants in some areas in the south. It is a working substance that continuously circulates in the refrigeration system and realizes refrigeration through its own state changes. The refrigerant absorbs the heat of the cooling medium (water or air, etc.) in the evaporator to vaporize, and transfers the heat to the surrounding air or water in the condenser to condense.
1. OHFC series refrigerant: R134a, R410A, R407C, R417A, R404A, R507, R23, R508A, R508B, R152a
1. R134a (tetrafluoroethane)
R134a refrigerant is currently recognized as one of the main alternative refrigerants in the world. It is often used in automotive air conditioners, commercial and industrial refrigeration systems, as a foaming agent in the production of hard plastic insulation materials, and can also be used to configure other mixed refrigeration. Agents, such as R404A and R407C.
Main application: It is mainly used as a refrigerant instead of R12, and is widely used in automobile air-conditioning and refrigerator refrigeration.
2. R410A
Under normal temperature and pressure, R410A is a non-azeotropic mixture of chlorine-free fluoroalkane refrigerant. It is a colorless gas. It is stored in a steel cylinder and is a compressed liquefied gas. Its ODP is 0, so R410A is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere.
Main application: R410A is mainly used to replace R22 and R502. It has the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect. It is widely used in household air conditioners, small commercial air conditioners, household central air conditioners, etc.
3. R407C
Under normal temperature and pressure, R407C is a non-azeotropic mixture of chlorine-free fluoroalkane refrigerant, a colorless gas, stored in a steel cylinder, and is a compressed liquefied gas. Its ODP is 0, so R407C is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere.
Main use: R407C is mainly used to replace R22, with the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect. It is widely used in household air conditioners and small and medium-sized central air conditioners.
4. R417A
Under normal temperature and pressure, R417A is a non-azeotropic mixture of chlorine-free fluoroalkane refrigerant. It is a colorless gas. It is stored in a steel cylinder and is a compressed liquefied gas. Its ODP is 0, so R417A is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere.
Main use: R417A is mainly used to replace R22, with clean, low toxicity, non-combustible, and good cooling effect. It is used for heat pumps (replacement of R22 for OEM initial installation) and air conditioners (replacement of R22 for after-sales).
5. R404A
R404A must not be a non-azeotropic mixed refrigerant that does not contain chlorine. It is a colorless gas at room temperature and pressure. It is stored in a steel cylinder and is a compressed liquefied gas. Its ODP is 0, so R404A is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere.
Main application: R404A is mainly used to replace R22 and R502. It has the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect. It is widely used in medium and low temperature refrigeration systems.
6. R507
R507 is a non-chlorine azeotropic mixed refrigerant. It is a colorless gas at room temperature and pressure. It is stored in a steel cylinder and is a compressed liquefied gas. Its ODP is 0, so R507 is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere.
Main use: R507 is mainly used to replace R22 and R502, with the characteristics of clean, low toxicity, non-combustibility, and good refrigeration effect. It is widely used in medium and low temperature refrigeration systems.
