Whois & Analysis for hvacdirect.com

Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort.

Its goal is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

Air conditioning (often referred to as AC, A.C., or A/C) is the process of removing heat from a confined space, thus cooling the air, and removing humidity.

Air conditioning can be used in both domestic and commercial environments.

This process is used to achieve a more comfortable interior environment, typically for humans or animals; however, air conditioning is also used to cool/dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and even to display and store artwork.

A heat pump is a device that transfers heat energy from a source of heat to a destination called a "heat sink".

Heat pumps are designed to move thermal energy in the opposite direction of spontaneous heat transfer by absorbing heat from a cold space and releasing it to a warmer one.

A heat pump uses a small amount of external power to accomplish the work of transferring energy from the heat source to the heat sink.

A furnace is a device used for high-temperature heating.

The name derives from Greek word fornax, which means oven.

The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces.

Wholesaling, jobbing, or distributing is the sale of goods or merchandise to retailers; to industrial, commercial, institutional, or other professional business users; or to other wholesalers and related subordinated services.

In general, it is the sale of goods to anyone other than a standard consumer.
