USE OF EXISTING PIPING WHEN CHANGING OUT AIR CONDITIONER AND AIR HANDLING UNIT
USE OF EXISTING PIPING WHEN CHANGING OUT AIR CONDITIONER AND AIR HANDLING UNIT
(OP)
Presently the lobby of our building is cooled by a 10 ton Air Conditioner --- the compressor and condenser are located about 150 ft from the bldg. An inside air handling unit with and evaporator is located in the bldg. Air conditioner compressor, evaporator, etc are about 30 yrs old and are to be replaced. Refrigerant will have to be replaced to meet present standards. To save on costs, can the existing buried piping connecting the compressor, condensor with the evaporator be used with the new refrigerant.
Thanks
Thanks

B.E.
You are judged not by what you know, but by what you can do.

There are some special substances for chemical cleaning on market, but the issue is whether chemical supplier could supply you a warranty that his process will not make damage to the new equipment.
If you want to save, you could also consider overhaul of the old compressor, many such units are of good quality and can work very long time with proper maintenance, and it is commercial guys aggressiveness that put such stuff out of business.
On the other hand, if you hunt modern concepts of energy efficiency such compressors will not be adequate, but than there is no way to be cost efficient. If you want to be cost efficient, keep the old stuff as long as possible.

In addition R12/R22 are so expensive now, any leak will cost you dearly. This unit probably had a useful life of 20-25 years.
Spare parts also will be harder to come by as it ages.
Get it all new and be good for the next 25 years.

Cost of labor,etc for removal. If piping can be used then it is a substantial cost savings when doing the replacement.
