REFRIGERATION CYCLE PHASE 2

In a residential air conditioning (AC) system, the evaporator is an essential component responsible for cooling the air that is blown into the living space. The evaporator coil is typically located in the indoor unit of the AC system and works by removing heat from the air that passes over it.

As the warm air from your home moves over the evaporator coil, the refrigerant inside the coil absorbs the heat and evaporates into a gas. This process cools the air, which is then circulated back into your home. The refrigerant gas is then transported to the outdoor unit of the AC system where it is compressed, releasing the heat absorbed by the evaporator coil.
A Thermostatic Expansion Valve (TXV) is an important component of an air conditioning system. Its function is to control the flow of refrigerant into the evaporator coil, based on the temperature and pressure of the refrigerant and the surrounding air.

The TXV is located between the liquid line and the evaporator coil, and it works by sensing the temperature of the refrigerant leaving the evaporator coil. As the temperature changes, the TXV adjusts the flow of refrigerant into the evaporator coil to maintain a constant superheat, which is the difference between the temperature of the refrigerant and its boiling point at the given pressure.

By controlling the flow of refrigerant, the TXV ensures that the evaporator coil operates at the optimal temperature and pressure, which improves the efficiency of the air conditioning system. It also helps to prevent the evaporator coil from freezing, which can damage the system and reduce its performance.

Overall, the TXV plays a critical role in regulating the flow of refrigerant through an air conditioning system, and it helps to ensure that the system operates efficiently and reliably.
Overall, the evaporator plays a crucial role in the cooling process of a residential AC system, as it is responsible for removing heat from the air inside your home and cooling it down before circulating it back into the living space.
