R134a Refrigerant

Refrigerant r134a is non-ozone depleting non-corrosive,non-toxic,non-global warming propellant.
Used as refrigerant in automobile air –conditioning ,household and com-mercial refrigerant applications.
Refrigerant r134a can also be used as aerosol, flame retardan , and blowing agent in pharmaceutical , agro-chemical , cosmetics and cleaning sectors.

R134a refrigerant is the latest refrigerant, which is a substitute for Freon refrigerant. Compared with other refrigerants, R134a is a very good refrigerant with many superior characteristics.

First, the cooling effect of R134a refrigerant is very good. It has high cooling efficiency and can lower the room temperature to the required temperature in a short time. Moreover, the refrigeration effect of R134a is very stable, and it can precisely control the constant temperature environment.

Second, R134 has very little impact on the environment. It will not destroy the ozone layer, nor will it cause other environmental problems. Therefore, this refrigerant is more environmentally friendly than traditional Freon refrigerants.

Application

1.In domestic refrigerators and air conditioners

R134a is widely used. It has the characteristics of efficient refrigeration, energy saving and environmental protection. Compared with the previous CFCs (chlorofluorocarbons) refrigerants, R134a can make cold boxes or air conditioners more energy-efficient and more environmentally friendly, thereby greatly reducing the cost of refrigeration equipment for consumers.

2. In commercial and industrial refrigeration.

R134a is also used in large-scale refrigeration equipment such as refrigerators in supermarkets and air conditioners in shopping malls. In these fields, it can provide more efficient and stable refrigeration effect, and can meet the refrigeration demand at high temperature.

3. In automotive air conditioning systems.

It can provide cool air in the car, keep the driver and passengers cool and comfortable in the hot summer, improve driving comfort and increase driving safety.
