Nope, just one type used for vehicles.................
R12 and R134a are two different types of chemicals used in vehicle refrigeration systems. If you mix the two together, you can corrode the system and cause major damage.
Applications and data are two types of software.
Operating systems and applications, like Windows XP and Microsoft Word.
There are two types of voice systems available Secure and Non secure
There are two basic types of utilty patents: the non-provisional and the provisional application. Both types of patent applications are held in confidence by the USPTO, they will not show your application to anyone. Design patents are always non-provisional applications.
Microsoft's user interface design tool for creating rich graphical interfaces for web and desktop applications that blend the features of these two types of applications
list 2 major types of internet application and their use
The r134a will degrade the rubber and your refrigerant will leak out. The two are not to be mixed anyways, get the conversion kit, it gives you the new O-rings so you don't pollute the atmosphere and break laws. Best to have it done professionally, in order for the ac system to work properly after being opened it will need to be vacuum pressurized prior to the r134a being put in.
It would be easier to answer, if you explained what the 'two types of coding' were.
Two types of computer software would be: 1. Application Software which would perform useful tasks for users. 2. Firmware, which is software programmed to electrically programmable memory devices on board mainboards or different types of integrated hardware carriers.
There are primarily two types of Multimedia applications (i) Real time and (ii) Non Real time. RT applications are audio/Video Teleconferencing/telephony and NRT applications are audio/video broadcasting etc, internet browsing etc.
The "a" in R134a is an indicator. There are two gases that are similar R134 and R134a. They both have the same chemical make up which is 2 hydrogen, 2 carbon and 4 fluorine. However in R134 all of the elements stay separated in a gaseous state. In R134a the elements combine together in different ways. Two hydrogens can be bonded with 4 fluorines or 2 carbons with 4 fluorines, etc. Lower case letters are the "organization" of the molecules and upper case letters are the different blends of the refridgerant.
