Air condition has become a necessity for people living in warm climates. If consumers are aware about air conditioning system then they can take better care of it. Using it appropriately will maintain its performance and efficiency.
Air condition – Definition
First modern AC system was designed by Willis Carrier in the year 1902. According to Willis Carrier an air condition
Maintains suitable humidity within all parts of the house or building
Removes excess humidity from the air in certain seasons
Supplies constant and adequate ventilation
Removes dust and foreign bodies from the air efficiently
Cools the room efficiently in certain seasons
Is even capable to heat the room in winter
Air condition mechanism
Home air condition is designed to remove the internal heat and blow in cool air. The air that is sucked in is blown over an arrangement of cold pipes known as evaporator (condenser) coil. It works similar to the cooling effect your skin feels, when water evaporates.
Refrigerant is a special liquid filled in the condenser coil, which transforms into gas as soon as it absorbs the heat. The refrigerant (gas form) is pumped in the condenser coil that is located in the exterior part of the house. The heat from the refrigerant transfers and condenses back to liquid. Compressor (a pump) is used to move refrigerant between two coils. In addition, change the temperature for condensation or evaporation of refrigerant in appropriate coils.
Connected to the condenser is a fan, which circulates air in the house. Hot air is light than cold air, so it rises up and gets sucked through the vent. In this way heat gets removed from the room and cools air gets blown inside.
This process continues until room reaches desired cooling temperature. The thermostat detects the temperature’s right setting and turns the air condition off. As soon as the cooling drops the thermostat turns the air condition on till room reaches specific temperature.
Probable performance issues
The mechanical system of air condition is complex and depends on certain facts for working correctly.
They are sized for meeting certain load
They are designed to contain specific amount of refrigerant
They are built with a purpose to allow definite amount of air flown across the coils
If there is a change in any of the above aspects, the system will display issues.
If more heat is produces in the house due to more appliance, people or changes in the house then the AC may be unable to keep up.
If the condenser coil rejects the heat to flow outside then the refrigerant capacity can get reduced and system performance can go down.
If refrigerant leaks out then the efficiency gets affected. You get less cooling and the system will be unable to handle the load that rises.
Other aspects to consider
Routine maintenance of replacing filters, cleaning dirt from coils and drains
Lighten the load like enhance insulation level or reduce air leakage
