Abstract: A refrigerant charging method for an air conditioning device in which carbon dioxide is used as a refrigerant includes a connecting step and a refrigerant charging step. In the connecting step, a cylinder containing the refrigerant is connected to a space in the air conditioning device intended to be charged by the refrigerant. A heater is interposed between the cylinder and the air conditioning device. In the refrigerant charging step, the refrigerant is moved to the intended charging space from the cylinder, via the heater. In the refrigerant charging step, further, the refrigerant that has exited the cylinder is heated by the heater so that a specific enthalpy of the refrigerant when it enters the intended charging space will be 430 kJ/kg or higher.

Abstract: Systems and methods for Indirect Evaporative Cooling and for Two Stage Evaporative Cooling for conditioning fluids such as air are disclosed. The Indirect Evaporative Cooling Systems comprise scalable indirect evaporative heat exchangers formed with polymer substrates that have been treated to render one surface substantially hydrophilic while the other is substantially hydrophobic, with channels for passage of primary (cooled) an secondary (cooling) air streams between them. The Two Stage Evaporative Cooling System comprise an indirect evaporation component where the fluid is pre-cooled indirectly with the abovementioned scalable heat exchangers, followed by a direct evaporation stage where the pre-cooled fluid is further cooled directly by adiabatic evaporative cooling. The device employing these systems is scalable, energy-efficient, uses aseptic materials, filters/clean incoming fluids (e.g. air), circulates disinfected evaporating liquid (e.g. disinfected water and has enhanced performance efficiency.
