Summer is a couple of months away, but there is never a wrong time to discuss HVAC – whether central air or ductless. With a sound air conditioning system, you will not have to suffer in hot weather conditions. This article will discuss everything you need to know about HVAC.
People have a general idea of what HVAC is… but there is nothing like a good old-fashioned definition to make things more transparent. HVAC stands for heating, ventilation, and air conditioning. It describes a system of transporting air from outdoors for cooling and heating purposes. You can use HVAC in a residential or commercial building.
HVAC is very common , but people usually only think of one specific type of HVAC product: central air conditioning. There are several types of air conditioning but we will focus on central air conditioning and one other type —ductless AC.
An ductless air conditioner is an air-conditioning system with two units… one outside and another inside which is connected with wiring and tubes for the refrigerant. The indoor unit is usually mounted on the wall and linked with the outdoor unit through wires and tubes that pass through a drilled part of the wall.
Since you don’t need ducts, this ductless air conditioner is easier to Install. However, this means each room in the building needs a ductless air conditioner.
Like the central air conditioning system, the ductless system uses a compressor, external air conditioner, and refrigerant features. Take a look at the steps below to learn more about how a ductless air conditioning works and how it differs from a central air conditioning system.
The external compressor from the outdoor air unit pushes refrigerant into the indoor unit’s evaporator coil using the refrigerant tube. There, the refrigerant turns to a hot gas which removes heat from the air that the indoor unit drew in.
After the refrigerant removes the heat, the system sends the cooler air to the room with the internal unit.
The refrigerant(now a hot vapor) gets transported to the external condenser coil, which converts the hot vapor into liquid refrigerant. The cycle then continues again.
HVAC ductless or central air conditioners are excellent additions to your home if you want to make your indoors comfortable. Start your HVAC journey now.
As its name implies, central air conditioning systems use a central unit to obtain the air it distributes. HVAC units circulate the cool air using supply and return ducts — the supply ducts transport cool air into the building. Then as the air becomes warmer, the unit uses its return ducts to suck the air back in.
Essentially, an HVAC air conditioner works by absorbing warmth or heat in a building and transporting it outside. That simple description contains several steps, which will be described below:
The return vents of the HVAC system drag hot air from the building through the return air duct, where the filters in the system remove particles from the air.
The now clean air now goes through the cold evaporator coil. Here, the liquid refrigerant in the evaporator coil turns to gas and absorbs the heat from the clean air.
After the heat is absorbed, the air becomes cool as it passes over the coil. Then, the HVAC fan sends the cool air back to the building using the ducts.
The system using a copper tube passes the refrigerant (which is now a hot vapor) into the compressor unit located in the external portion of the air conditioner unit outside the building. The compressor pressurizes the hot refrigerant vapor and passes it to the condenser in the external unit.
The fan in the external air conditioner then draws in air from outside into the condenser. This air removes the heat from the refrigerant. The refrigerant now reverts to its liquid state, and the copper tube transports it back to the evaporator. The whole process then repeats itself.
