there are 2 ypes of vrf system which are 2 pipe and 3 pipe systems.
2 pipe is where indoor units can either cool or heat only
3 pipe systems can cool and heat at the same time as i understand the is known as a heat recovery system please correct me if i am incorrect.
what i want to know is what is the function of the third pipe is it that the third pipe always feeds the units which are on heat mode via the branch boxes.
thanks for your time and help
