Abstract
The paper deals with the topic of refrigerants, their historical evolution, applied legislation and trends
in maritime affairs. Regarding the Environmental care paper considers the impact of refrigerants of
refrigeration systems, both on stationary plants on land and on plants on board. New regulations
of the European Union, and IMO maritime organization, require the reduction and complete
abolition of harmful synthetic refrigerants and the introduction of new refrigerants that will have a
significant economic and environmental impact. The trend is the introduction of natural refrigerants
as a replacement for existing environmentally unacceptable ones. On-board refrigeration systems
introduce natural refrigerants such as ammonia and carbon dioxide into applications that require lower
refrigeration temperatures. Absorption cooling plants are introduced into air conditioning applications
on board the ship. They work with water/lithium bromide (H2O/LiBr) mixtures, thus increasing the
efficiency of the plant and reducing the impact on the environment.
