The Properties To Look For In An Ideal Home Air Conditioner Refrigerant

If you need to replace the refrigerant in your home air conditioner, you need to know what the ideal properties are going to be.  These properties will ensure that the refrigerant you choose works with your air conditioner and provide you with the best experience.  There are a number of properties that you have to know about and you should understand why they are important to look for.

The Vapor Density

The first property that you should be looking for is the vapor density of the refrigerant.  For a home air conditioner, you will need smaller vapor density because you will have a smaller compressor.  Larger vapor density will be better for larger systems, but not ideal for your home.

Most of the common home air conditioner refrigerants will have smaller vapor density.  This is due to the fact that they have been created with the smaller compressor in mind.  If you are unsure about the vapor density of the refrigerant you are looking at, you will need to talk to an air conditioning technician.  They will be able to tell you the best refrigerant for air conditioners and whether or not it is right for your air conditioner.

The Thermal Conductivity

Another property that you need to look at in your refrigerant is the thermal conductivity.  This is important because it will impact the heat transfer during condensation and evaporation.  You will want to look at refrigerants with a high thermal conductivity as this increases the speed of the transfer.

If you have low thermal conductivity, the air conditioner will not be able to cool at the correct rate.  Your refrigerant will work slower and this will increase the time and energy that you need to use to cool your home.  This will also make the unit less efficient overall and this can cause a range of other problems.

The Enthalpy Of Vaporization

The enthalpy of vaporization is different to the thermal conductivity, but will also play a role in the transfer of heat.  The difference is that the enthalpy of vaporization is the absorption of heat by the refrigerant.  This is why you need to have a high level of enthalpy of vaporization in the ideal refrigerant for your home air conditioner.

If you have a low enthalpy of vaporization, less heat will be absorbed during the refrigeration process.  This will decrease the effectiveness of the air conditioner and increase the time it takes to cool your home.  This will also increase the energy consumption of the air conditioner as it has to run for longer to achieve the temperatures that you want.

The Critical Temperature

When looking at refrigerants, you will notice that they have a critical temperature.  This is important because it will impact the isothermal energy transfer.  You will want a refrigerant that has a large range of isothermal energy transfer because this will ensure that the air conditioner can cool quickly and effectively.

The critical temperature of the ideal refrigerant will need to be above the condensing temperature.  If the critical temperature is lower than this, your air conditioner will not be able to operate correctly.  This can also lead to a number of other functional problems that you will want to avoid.

The Dielectric Strength

The dielectric strength of the refrigerant is not something that you always have to look for.  This will only be an ideal property when you have a hermetic arrangement in your air conditioner.  This is due to the way that these air conditioners will operate.

An air conditioner with this arrangement will have motor winding which is cooled by the refrigerant vapors on the way to the suction valve of the compressor.  The dielectric strength is important because it will impact the cooling ability of the sealed compressor unit.  If you do not have a hermetic arrangement in your air conditioner, you will not have to worry about this property.

The Leak Tendency

Many people do not realize that the low leak tendency is something that you need to look for in a refrigerant.  Refrigerant can leak from the system and this will increase the number of times you have to recharge the system and will cause other problems to the wearing out of the joints.  There are some refrigerants that are less likely to leak than others and they are the ones you want to get.

Denser refrigerants will have lower leak tendencies and you need to consider this.  When considering leak tendency, you should also consider leak detection.  Refrigerants with distinct colors will be better for this as you can easily identify that there is a leak.

The Toxicity

The ideal home air conditioner refrigerant will be as non-toxic as possible.  This is due to the fact that humans and animals can come into contact with the refrigerant and you need to be safe.  If the refrigerant is toxic, you should not use it in your home air conditioning system.

These refrigerants will negatively affect your health and the health of your family.  The toxicity of the refrigerant can last for longer than you have the liquid and you need to consider this.  Residue from the refrigerant in the air conditioning system can linger even after you have replaced it with a less toxic alternative.

The Availability

The perfect home air conditioner refrigerant will be easy to come by.  You should always look for refrigerants that are easily available in your area and that you will be able to get in the future.  If you have to source the refrigerant from the other side of the country, you should reconsider using it.

You also need to consider if you can easily get the refrigerant at short notice.  You might need more refrigerant when there is a leak in the system and if you have to wait, you could find yourself in a very warm house.  You also need to be able to easily get the refrigerant for your regular maintenance schedule.  There are many properties that you need to look for in a refrigerant for your home air conditioner. These properties will ensure that your air conditioner works correctly and that you are always safe.
