How to Hire the Best HVAC Installation Experts
The expectation of individuals are met through a three step process. Controlling the temperature of air along with controlling of moisture, filtration of air among others is the main objective of HVAC. When heating, ventilating and air conditioning is involved it forms a complete system which is known as HVAC. A compressor, fan, evaporator coil and condenser is contained in an air conditioner for it to work. Absorption of heat from the air is transferred to the refrigerant which is then pumped to the outdoor segment. The HVAC system contains vents, thermostat, furnace, heat exchanger, evaporator coil, refrigerant coils, ductwork and condensing unit as the main components.
The role of an evaporator coil is to cool air when the thermostat is set to lower temperatures. The purpose of an evaporator coil is the reverse role of a heat exchanger. The evaporator coil is located to the mental enclosure on the furnace’s exterior, to the top or side and also is known to work as an automobile radiator resulting to producing cool air. System of ducts that transport air warmed or cooled within the home is a duct work.
Ducts are made of lightweight aluminum but can be made from steel, fiberglass, fabric and flexible plastic. Thermostats are set on prominent easily accessible wall as they are the most visible feature in a HVAC system. So as to keep the temperature of the home at a desirable rate then the thermostat is set manually or programmed in advance.
Warm air or cool air from the heat exchanger or the evaporator coil respectively is trigged by the thermostat. The size of the furnace is quite large and thus requires a substantial amount of space. Heating a supply of air is the main purpose of the furnace which is then distributed to the various rooms of the home. The process of heating is accomplished using the following sources of heat that is combustion, solar energy, electric resistance and heat pump.
Combustion as a heat source involves burning of natural gas, propane, oil or coal. The location of the heat exchanger is inside the furnace which switches on the furnace when its activated by a thermostat to produce warmer temperatures. The working of the heat exchanger is to draw in cool air, heat the air and circulate the resulted heated air through the ductworks and vents.
A component of the HVAC system that is connected to the evaporator coil and is installed to outside the home is the condensing unit. A refrigerant gas is filled in the condensing unit which is then cooled to a liquid by the heat exchanger then pumped to the evaporator coil to be evaporated to the gas.
