|
Air handler |
Air moving and /or mixing unit: may include blower, filters, dampers etc. |
Auxiliary |

Boiler |
A sealed chamber in which water is converted to steam or is heated for circulation in a hydronic heating system |
| Btu |
British thermal unit. |
| Compressor |
A mechanical pump in a refrigeration system that recovers refrigerant vapor and rises its temperature and pressure to the point where it can be condensed for reuse. |
| Condensate |
Water vapor that liquefies due to the lowering of its temperature to the saturation point. |
| Condensate pump |
A water pump which disposes of, or re circulates, collected condensation. |
| Condenser |
A heat exchanger in which compressed refrigerant vapor is cooled until it becomes a liquid. |
| Condensing unit |
The compressor, condenser, receiver, and controls that may come as a packaged unit |
| Cooling coil |
Any section of coiled tubing used to lower the temperature of the surrounding area: usually an evaporator. |
| Damper |
A panel or baffle used to control the volume of flowing air |
| Decibel |
A unit of measure for the loudness of sounds |
| Defrost cycle |
The period during operation of refrigeration equipment when frost is melted off the evaporator.. |
| Dehumidifier |
An air cooler that removes moisture from the air. |
| Diagnosis |
Evaluation of what, if anything, is wrong with a system and what must be done to repair it. |
| Disconnect |
A switch or box that cuts off electrical power to a machine being serviced. |
| Drip pan/drain pan |
A pan used to catch and collect evaporator condensate. |
| Duct |
A pipe or conduit through which air is delivered. |
| Duct heater |
A heater mounted inside an air delivery duct that provides supplemental heat to delivered air |
| EER |
Energy efficiency ratio; the number of Btu's produced per watt of electrical power consumed by an air conditioner. |
| Efficiency |
The amount of usable energy produced by a machine |
| Electric heat |
Any heating system which the prime energy source is electricity |

| Heat pump |
A system which can be reversed to heat or cool the controlled space |
| Humidifier |
Adds water vapor to the air to increase humidity |
| Infrared heat |
Heater that converts flame energy into radiant energy |
| Package unit |
A system with all the major components contained in a single cabinet |
| Pilot |
A small constant flame used to ignite the main gas burner |
| Refrigerant |
Any substance that transfers heat from one place to another, creating a cooling effect |
| Register |
A grille with adjustable louvers for controlling the direction of discharge air |
| Self-contained system |
A system that can be moved without disconnecting refrigerant lines |
| Split system |
An air conditioning system having the evaporator and the condenser separate from one another |
| Thermostat |
A temperature-sensitive electrical circuit control that is responsive to air temperature |
| Through-the-wall unit |
A type of unit in which the chassis is mounted through the outer wall with the evaporator inside and the condenser outside |
| Warranty |
An assurance of the product's proper operation and performance |
| Window unit |
An air conditioning which is mounted in a window |
