0 a type of gas used especially in aerosols (= containers that force out liquids in very small drops) -- 氫氟碳化合物
The standard allows for hydrocarbons, which are flammable, being used as a refrigerant in certain circumstances instead of the usual hydrofluorocarbons, which are inert.
What recent representations he has received on the use of hydrofluorocarbons at the millennium dome.
Only very small amounts of hydrofluorocarbons would have been purchased since 1995.
Information on the amounts of hydrofluorocarbons purchased since 1995 is not collected in the form requested.
It is anticipated that all equipment using hydrofluorocarbons will be replaced by equipment using more acceptable refrigerants within the present deadline.
The voluntary policy on reducing leakage of hydrofluorocarbons has had a positive impact in terms of raising awareness.
The policy also states that hydrofluorocarbons should only be used where other safe, technically feasible, cost effective and environmentally acceptable alternatives do not exist.
These estimates are based in part on assumptions about charges and leakage rates of hydrofluorocarbons from refrigeration systems in nine different refrigeration and air conditioning sectors.
