Página 9 de 12 Refrigerant recycling: To clean the refrigerant by oil separation and single or multiple passes through devices, such as replacesible core filter-dryers, which reduce moisture, acidity and particulate matter. This term usually applies to procedures implemented at the job site or at a local service shop. Refrigeration: The process of removing heat from one place where it is not wanted and transferring that heat to a place where it makes little or no difference, ie outside. Relative humidity: The amount of moisture contained in the air as compared to the amount the air could hold at that temperature. Relay: A small electromagnetic device to control a switch, motor, or valve. Remote system: Often called a split-system where the condenser is located away from the evaporator and /or other parts of the system. Rotary compressor: A compressor that uses rotary motion to pump refrigerant vapor/or liquid. It is a positive-displacement pump. Schrader valve: A valve similar to the valve on an auto tire that allows refrigerant to be charged or discharged from the system. Scroll compressor: A compressor that uses two scroll-type components to compress vapor. Seal unit: The term used to describe a refrigeration system, including the compressor, that is completely welded closed. The pressures can be accessed by saddle valves. SEER (Seasonal energy efficiency ratio): This measurement of an air conditioning or heat pump system''s energy efficiency takes into account the cooling efficiency of the system under various weather conditions. SEER is determined by dividing the total cooling provided during worm months (in BTU''s) by the total energy (watts-hours) consumed during the same period. The higher the SEER number the less wattage use per hour. |
