Are gases that do not emit CFCs (chlorofluorocarbons), chlorine-based substances that are very harmful to human health and the environment, and also cause damage to the ozone layer, responsible for protecting the Earth against solar radiation. The most common types of ecological gases in air-conditioning units are R-410A and R-407C.
Recharging of ecological gas: the handling of R410-A is similar to R-22. The difference is that the R410-A must be completely removed from the system so that the new load is taken. It is not recommended to only complement the gas charge. The amount of gas will depend on the device and manufacturer.
The use increasingly common these gases meets the requirements of the Montreal Protocol and Ordinance No. 3,523. Many air conditioning manufacturers already have adapted to these requirements.
Ordinance No. 3523
The document deals with standards for air quality in air-conditioned environments, considering the concern for the health, well-being, comfort, among others.
