Refrigerant Leaves The Evaporator As A

Refrigerant leaves the evaporator as a

Refrigerant enters the compressor as low-pressure, low-temperature gas, and leaves the compressor as a high-pressure, high-temperature gas.

What happens when the refrigerant enters the evaporator?

The refrigerant vapour enters the evaporator where it absorbs heat from the space being cooled, causing the refrigerant to boil. As it continues through the evaporator coil the vapour is superheated turning the refrigerant to gas before it enters the compressor and starts the cycle over again.

Where does refrigerant go when it leaves the condensing unit?

Once the refrigerant reaches its saturated or boiling temperature, the condenser's next job is to sub-cool the refrigerant. This ensures that as the refrigerant leaves the condenser down the liquid line, a full column of liquid is making its way toward the metering device.

What state does refrigerant leave the receiver?

And, since the refrigerant's pressure is constant, the refrigerant below the interface is subcooled. Normally, the refrigerant leaving the receiver is picked up below the interface toward the bottom of the receiver, allowing the refrigerant to leave in a subcooled state.

What happens when refrigerant passes through the condenser?

Refrigerant flows through the compressor, which raises the pressure of the refrigerant. Next the refrigerant flows through the condenser, where it condenses from vapor form to liquid form, giving off heat in the process.

Where does the refrigerant enter the evaporator coil?

The Low Side: Absorbing the Heat Cold, low pressure refrigerant leaves the expansion valve and enters the evaporator coil.

What happens to the refrigerant when it leaves the metering device?

METERING DEVICE at work Low-pressure liquid that is leaving the metering device is boiling at saturated pressure-temperature. The process of a refrigerant changing its state (from a liquid to a vapor) in the metering device is called flash gas. Flash gas is what cools the refrigerant liquid in the metering device.

Where does the refrigerant flow to after it leaves the compressor?

After leaving the compressor, the hot vapor refrigerant enters the next stage of the cycle, condensation. During the condensation stage, the refrigerant enters a condenser and flows through a series of S-shaped tubes. As the hot vapor flows through the condenser, cool air is blown across the tubes by a fan.

What is the state of the AC refrigerant leaving the evaporator?

As refrigerant travels through the evaporator, it absorbs heat from the air. As it absorbs heat, it vaporizes. If the system operates according to design, the refrigerant will be 100% vapor as it nears the exit of the evaporator. Before leaving the evaporator, the vapor continues absorbing heat, becoming superheated.

What is the state of the refrigerant as it enters and exits the receiver drier?

Refrigerant from the condenser enters the receiver drier through the inlet port. The vapor rises to the top, while the heavier liquid refrigerant drops to the bottom. It passes through the filter and desiccant before it's stored at the bottom of the tank.

How does refrigerant move through a condenser coil?

The Condenser Coil and Fan Once most of the heat has been expelled, the refrigerant can cool back down into a liquid state. It then passes through an expansion valve that changes the cooled refrigerant into a vapor. This cold vapor then goes back into the evaporator coil where it can absorb more heat.

What is the function of an evaporator coil?

The role of the evaporator coil Located inside the blower compartment or air handler, the evaporator coil holds the chilled refrigerant that the compressor moves into it. As the air from the blower fan moves over the coil, the cold refrigerant removes the heat from your home's air.

What happens to the refrigerant as it passes through the metering device quizlet?

What happens to the refrigerant as it passes through the metering device? The refrigerant drops in pressure and temperature as it passes through the metering device. A small portion of the refrigerant flashes to a vapor, cooling the remaining liquid.

Can the evaporator be thought of as a heat sponge?

The evaporator can be thought of as a "heat sponge." Vapor is more dense than liquid and, as the liquid refrigerant boils, it has a tendency to sink. The only location where the refrigerant vapor is superheated is in the evaporator.

What is the state of refrigerant between the metering device and the evaporator?

In the metering device, refrigerant is fully liquid as it changes from high to low pressure liquid. It passes back to the evaporator and repeats the process.

What happens to the pressure and heat in the evaporator?

The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.

What are the four phases through which a refrigerant passes in the basic refrigeration cycle?

A refrigeration cycle has four major components: the compressor, condenser, expansion device, and evaporator.

What are the 4 phases of refrigerant?

How Does Refrigerant Work?

Stage 1: Evaporator Coil. Your refrigerant's journey begins at your evaporator coil, which is located inside the indoor unit in your home.
Stage 2: Compressor. ...
Stage 3: Condenser Coil. ...
Stage 4: Expansion Chamber.

How do refrigerants transfer heat?

In the evaporator, heat transfers from the process recirculating fluid (higher temperature) into the refrigerant (lower temperature). The condenser transfers this heat from the refrigerant (higher temperature) to the cooling source (air or water) at a lower temperature.

Which way does refrigerant flow in cooling mode?

When such is the case, the system is operating in the cooling mode, since the refrigerant always flows to the condenser first upon exiting the compressor. It can also be seen that the “U-bend” directs the refrigerant from the indoor coil, in this case the evaporator, back to the compressor.
