By 52%-54% denisty indicator of lithium bromide, it is used to be absorptive refrigerant, hypnagogue and mitigative of medicine, and also to be electrolyte in ion-battery.
About 80% of the chlorine in the atmosphere is a legacy of chlorofluorocarbons, chemicals used in aerosol sprays and as refrigerants starting in the 1930s.

That is why some companies are trying to build units that do away with refrigerants entirely, which means coming up with a totally different method of absorbing heat.
Users, the company says, get to control humidity and temperature independently of one another, while reducing energy use by between 50% and 90% and the environmental impact of refrigerants by 85%.
