| Word | Definition |
|---|---|
| Airflow | Air volume measured in CFM (cubic feet per minute) |
| AHRI | The Air Conditioning, Heating and Refrigeration Institute (AHRI) is a trade association that certifies the performance ratings of heating and cooling products using independent third-party testing |
| BTU/H | British Thermal Units per Hour, a measure of cooling or heating capacity |
| Capacity | Refrigeration capacity by system usually measured in BTU/H or Tons for cooling. One Ton is equivalent to 12,000 BTU/H |
| CFM (Cubic Feet per Minute) | Measurement of air volume |
| Compressor | A component of the refrigeration cycle, which draws low pressure/temperature refrigerant gas from the evaporator (indoor unit) and delivers in high pressure/temperature form to the condenser (outdoor unit) |
| Decibels (dB) | the intensity of sound is measured in decibels (dB) |
| Ducted Split Systems | A system composed of an outdoor condensing unit connected by refrigerant pipes to a ducted type indoor evaporator unit (Fan Coil or Air Handler) |
| Ductless Split Systems | A system composed of an outdoor condensing unit connected by refrigerant pipes to a non-ducted type indoor evaporator unit (Hi-wall, Cassette or Console) |
| EER (Energy Efficiency Ratio) | Efficiency rating of air conditioning or heating units in cooling mode. It is calculated by dividing the system capacity output per hour by its power consumption (watts). The higher the EER, the more efficient the system |
| Energy Star | Is a joint program of the US Environmental Protection Agency and the US Department of Energy. Energy Star qualified ductless systems are high efficient products that are cost effective solutions to deliver heat or cool air directly into different zones in many residential or commercial applications |
| Heat Pump | Cooling/Heating system can reverse the direction of refrigerant flow to provide heating or cooling to the indoor space as needed |
| HSPF | measurement of the heating efficiency of heat pumps. The higher the HSPF, the more efficient the heat pump |
| HVAC | Heating, Ventilation and Air Conditioning |
| IAQ | Indoor Air Quality |
| Indoor Unit | The evaporator unit which contains a heat exchanger coil, fan, air filters and remote signal receiver |
| Inverter Technology | Compressors with Inverter-driven Technology reduce power consumption and thus saves energy by varying the compressor speed to meet load requirements. The system operates at a more steady revolution, maintaining desired temperature more evenly for better comfort |
| Multi-Zone Ductless systems | System features a single outdoor unit (condenser) connected to multiple indoor units, providing zoning capability through individual remote thermostats that control temperature and air flow for each room or zone |
| Outdoor Unit | The condensing unit which contains compressor, condenser coil, propeller fan and circuit board |
| Operating Cost | Total cost of running your cooling and heating system based on energy consumption and rate |
| PTAC | Packaged Terminal Air Conditioner |
| PV (Solar) Module | In Photovoltaic (Solar) Module light energy converts into electricity. PV system consists of many jointly connected solar cells |
| Refrigerant | A gas/liquid substance used on refrigeration cycle to provide cooling by absorbing and dispersing heat. GREE Ductless systems use environmentally friendly R410A refrigerant |
| SEER (Seasonal Energy Efficiency Ratio) | Efficiency rating of air conditioners and heat pumps over the course of the cooling season. The higher the SEER, the more efficient the system |
| Solar Inverter | Solar inverter is a new technology used on GREE NEO Solar Series. Based on PV generation principle, solar energy is converted into electric energy to run the system, replacing partially commercial power and reducing total power consumption and energy bill. Solar Inverter has a power supply control module which automatically adjusts the power supply of solar energy and commercial power to reach total input power |
| Ton | Measurement of system cooling capacity. 1 Ton is equivalent to 12,000 BTU/H |
| Zoning | Ductless systems manage environments individually with remote thermostats that control the temperature and air flow for each room or zone. In multi-split ductless systems, you can set different temperatures for different rooms or areas according to individual preference |
