HVAC Machine Systems
I have lived in various dwelling spaces from motels to houses and one must have machine is a HVAC system. This machine system helps the human body to maintain a homeostatic temperature. Our skin contains thermoreceptors that respond to temperature changes. When the temperature is too high our skin begins to sweat to release heat, whereas when the temperatures are too cold our skin shivers to increase body temperature. The HVAC system assists us so that our bodies don't have to respond to changing temperatures when indoors.
HVAC stands for heating, ventilation and air conditioning and it is this machine system that is used to control the temperature within an enclosed space by heating and cooling the air. The main types of HVAC systems are: split systems, hybrid systems, duct-free systems and packaged heating and air systems.☆Split systems have indoor and outdoor units that are connected using a copper tubing.
☆Hybrid systems are energy efficient so that choose between two energy sources to control the room temperature.
☆Duct-free systems are mounted mini split systems that are connected by electrical wiring and coolant tubing.
☆Packaged heating and air systems contain all components of the HVAC system in one unit connected to ductwork by a single hole in the wall of the dwelling space.
There are 6 main components of the HVAC machine:
1. Thermostat is the sensor that controls the room temperature by determining when the heater or air conditioner will turn on and off.
2. Heat exchanger which is activated by the thermostat to heat your dwelling space by absorbing heat and warming cool air within the space.
3. Blower motor pushes the warmed air throughout your dwelling space once the air is heated.
4. Combustion chamber burns air and gas fuel to heat your dwelling space.
5. Compressor is located outside your dwelling space and releases hot air to the outside which results in the air being cooler inside.
6. Evaporator coil lowers the temperature in your dwelling space by absorbing heat, which is achieved when liquid coolant spraying valves evaporates the liquid coolant making it a gas.
