Clean Air Act

1. The Clean Air Act does not allow ANY refrigerants to be vented into the atmosphere. (Web site)

Systems

Heating

1. These mixtures are useful as refrigerants for heating and cooling applications. (Web site)
2. As environmental requirements change, the heating and cooling industry must phase out existing refrigerants. (Web site)

Work

1. In addition, the new substitute refrigerants would not work well without making some changes to system components.

Air Conditioning

1. The new study factored in the expected growth in demand for air conditioning, refrigerants, and other technology in developed and developing countries.

Water

1. That water causes serious problems when mixed with refrigerants.
2. They use water, oils or other fluids as refrigerants. (Web site)

Ammonia

1. Ammonia carries a B2 rating under ASHRAE Standard 34 rating classification, as opposed to an Al rating for most of the HFC refrigerants.

Chemicals

1. The conduction mediums such as water, air, ice, and chemicals are referred to as refrigerants. (Web site)
2. Freon Trade name for a series of man made chemicals or refrigerants used in refrigeration systems.

Technician

1. To become certified to purchase and handle refrigerants, a technician must pass a written examination specific to the type of work in which they specialize.

Production

1. Along with prohibiting the production of ozone-depleting refrigerants, the Clean Air Act also mandates the use of common sense in handling refrigerants.
