Thermostats are relatively easy to replace, but it’s important to choose a model that is compatible with your HVAC system. Modern programmable or smart thermostats can also improve energy efficiency by optimizing heating and cooling schedules. 6.Expansion Valves The expansion valve regulates the flow...
Expansion: The high-pressure liquid refrigerant goes through an expansion valve where it becomes low-pressure liquid before returning to the evaporator coil. Circulation: An AC also has fans that circulate indoor air over its cold evaporator coil and then distribute cooled air throughout occupied spa...

Two metals with different rates of expansion fastened together. When heated or cooled they will warp and can be made to open or close a switch or valve. BOILING POINT The temperature at which the addition of any heat will begin a change of state from a liquid to a vapor. BRITISH THERMAL...
HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distributi
This location ensures that the tubes inside the coil are always full of water. A valve located at the inlet, or upstream, of the coil may modulate to the point where the water just trickles through the tubes, not filling the entire tube diameter. The result is unpredictable heat transfer ...
1.Heating and Cooling Split System: This is the most common type of HVAC system. It consists of two units: the indoor unit (that contains the evaporator coil, electrical components, and an expansion valve) and the outdoor unit (that houses the condenser coil, compressor, and fan). ...
