Air Conditioner
Air conditioning means getting heat from inside of the building and reject it to the outside and briefly it would be the heat transfer from inside to out side of a building or vice versa.
It's simple in word but complicated in process. Many items are involved to serve an enjoyable air to residents in a hot summer.
An installer must know all the physical definitions and rules to create an efficient air conditioning system. AC installation is not only connecting the wires and refrigeration lines and start the system; this would not be the scenario for a professional installation. There are several and several steps to do the best AC and heat pump installation; first in terms of environmental considerations and then getting the maximum performance of the system.
All depends on the best unit size and capacity selection, accurate old unit removing, proper running line sets, and meticulously new AC installation regarding to the refrigeration thermodynamics.
If the installer considers and complies with the all steps mentioned above but not the refrigeration thermodynamics, the outcome of the installation WOULD NOT BE the expected process.
Balancing the system based on the heat transfer parameters is the most important part of the AC installation that an installer MUST know and MUST do it. After starting the AC system an experienced technician has to check all the thermodynamic items involved in the refrigeration process. By checking the pressure gauges a professional technician must not go to the last step to add or reduce the amount of refrigerant in the system; there are lots of symptoms to find out weather the system is working properly or its unbalanced.
Superheat and subcooling are the definitions that a technician must know them and use them to check the system performance. By maintaining the superheat and subcooling the technician is able to diagnose the system problem, look for it, and find out what the issue is.
Air circulation components such as duct system, supply and return boots, air filter, dampers, fan motor, and … have important role in air conditioning efficiency that must be checked by the technician if any symptoms of unbalancing in the system is visible.
After all the surveys, an experienced technician would regulate the amount of the refrigerant by considering all the environmental and practical aspects of this process.
