Source of cooling. Cooling delivery is recorded in a separate data field. Use of fans or blowers by themselves without chilled air or water is not included in this definition of cooling. Stand-alone dehumidifiers are also not included.

Unit of Measure |
|
|---|---|---|---|
| Split DX air conditioner | Split direct expansion | None | |
| Other | Other | None | |
| Vapor compression chiller | None | ||
| Unknown | Unknown | None | |
| Absorption chiller | None | ||
| None | None | None | |
| District chilled water | None | ||
| Not applicable | Not applicable | None | |
| Evaporative cooler | A cooler that cools indoor air by moisture evaporation, thereby lowering its dry-bulb temperature and raising its wet-bulb temperature, all at a constant energy (adiabatic) level | None | |
| Packaged terminal air conditioner | A packaged terminal air conditioner, or PTAC, is a self-contained air conditioning system commonly found in hotels, motels, senior housing facilities, hospitals, condominiums, apartment buildings, add-on rooms and sunrooms. | None | |
| Split heat pump | A system that generally consists of two separate units. One comprised of the compressor and the condenser elements, and the other comprised of evaporator and expansion valve, connected by refrigerant tubing and a reversing valve. The flow of the refrigerant depends on whether the system is in cooling or heating mode. | None | |
| Packaged terminal heat pump | A Packaged terminal heat pump, or PTHP, is a factory-packaged refrigerant-based heat pump with no air distribution system other than a built-in fan. | None | |
| Variable refrigerant flow | System supporting variable motor speed and thus variable refrigerant flow rather than simply on/off operation. | None | |
| Packaged unitary direct expansion RTU | A unit that includes all the components- evaporative coil, compressor, expansion valve, condenser coil, and fans that's installed outside and the supply air is ducted inside. A separate heating source- electric or gas pack- is added if needed | None | |
| Packaged unitary heat pump | Factory-packaged refrigerant-based heat pump with an air distribution system and a reversing valve to alter the flow of refrigerant based on the need. | None | |
| Single package vertical air conditioner | Compact through-the-wall packaged system capable of providing total heating and cooling functions for a single zone or multiple rooms, designed with sufficient air-handling capacity for ducted installations. | None | |
| Single package vertical heat pump | Compact through-the-wall packaged system with heat pump, capable of providing total heating and cooling functions for a single zone or multiple rooms, designed with sufficient air-handling capacity for ducted installations. | None | |
| No cooling | None | ||
| Chiller | Generic chiller | None | |
| Heat pump | Generic heat pump | None |
