Mixing refrigerants, such as R600 (isobutane) and R134a (1,1,1,2-tetrafluoroethane), is not recommended and can be dangerous. These refrigerants have different properties and are not designed to be used interchangeably. Here's what can happen if you put R600 (isobutane) in a compressor designed for R134a:
Inefficiency: The performance of the cooling system will be severely compromised. The compressor may not be able to handle the different properties of R600, leading to poor cooling efficiency or even a complete breakdown of the compressor.
Safety Hazard: R600 (isobutane) is a flammable refrigerant, whereas R134a is not flammable. Introducing a flammable refrigerant into a compressor not designed for flammable substances can lead to a safety hazard, as it increases the risk of fire or explosion.
Damage to the System: The compressor and other components of the cooling system may suffer damage due to the differences in pressure, lubrication requirements, and other characteristics between the two refrigerants.
Voiding Warranty: If the cooling system is under warranty, using the wrong refrigerant can void the warranty, leaving you responsible for any repair or replacement costs.
In any refrigeration or air conditioning system, it is essential to use the appropriate refrigerant specified by the manufacturer. Mixing different refrigerants or using the wrong refrigerant can have severe consequences and should be avoided. If you believe there is an issue with the refrigerant or the cooling system, it's best to contact a qualified HVAC technician or a professional refrigeration service provider to diagnose and resolve the problem safely.
