DEFINITIONS The following terms are provided to give a ready reference to the meaning of some of the words contained within this manual. These definitions may differ from those given by a standard dictionary. Ambient air temperature: The temperature of the air surrounding a person or object. Charging station: An air conditioning system service unit which is capable of evacuating and charging an air conditioner. Condensation: The process of changing a vapor into a liquid. Desiccant: A material used in the receiver/drier bottle, designed to absorb moisture from the refrigerant. Heat load: The amount of heat which the air conditioner is required to remove from the aircraft cabin. Inches of mercury: A measurement of pressure, normally used for pressures below atmospheric, one inch of mercury is equal to approximately one half pound per square inch.
AIR CONDITIONER SERVICE MANUAL EC130-200M-1 Revision 6 Page 2 Pressure, ambient: The pressure of the air surrounding a body, normally measured in Pounds Per Square inch, or PSIG. Refrigerant: A fluid which is used in an air conditioning system to absorb heat from the cabin and carry it outside the helicopter where it can be transferred to the outside air. Relative humidity: The ratio of the amount of water vapor in the air to the amount of water vapor required to saturate the air at the existing temperature. Thermostat: An air conditioning control which senses the temperature of the evaporator coil and causes the system to cycle or by-pass to maintain the proper temperature of cooling air. Vacuum: A negative pressure, or pressure below atmospheric; it is usually expressed in inches of mercury. Vapor: The gaseous state of a material. 6.
