Definitions

  • ammonia increases the production costs enormously, especially in the field of air conditioning, considering the sophisticated and expensive safety systems provided in such apparatus.
  • the present invention also relates to a method for conditioning air with a refrigerant fluid which is not harmful to at least the ozone layer, said refrigerant fluid being a coolant belonging to the class of hydrocarbons and having no negative potential effect against the ozone layer and having no potential greenhouse effect and has flammable limits defined respectively as minimum and maximum concentration of said coolant apt to propagate the flame through a mixture of said coolant and air in preset temperature and pressure conditions, characterized in that it comprises the steps of: generating at least a first air flow having a selected rate of flow adapted to hit for a preset time all the electric and/or electronic and mechanical members adapted to the operation of an air conditioner for dissolving a possible minimum or maximum concentration of said coolant falling within said flammable limits and adapted to activate a compressor of said air conditioner, at the end of said preset time, and at the same time of its safety and control systems.
  • a timer for turning on and off the conditioner or the other elements.
  • a thermostat for turning on and off the conditioner or the other elements.
  • the first safety zone is in fact provided with such dimensions as to prevent the formation of a minimum or maximum concentration of coolant (propane) which may fall outside those maximum or minimum concentrations wherein the coolant becomes flammable.
