Old coil with HVAC Refrigerant Leaks
Old Leaking Condenser Coils (also referred to as freon leaks) can cause serious issues with HVAC heat pump equipment. HVAC refrigeration circuits are designed and built to hold the refrigerant. It is a sealed hermetic system. The HVAC refrigeration circuit should never need refrigerant. An HVAC refrigeration system does not burn refrigerant. The refrigerant is used over and over again to move heat from one place to another. Aside from a leak, once the refrigeration system is properly charged, the system should never need refrigerant for the life of the equipment. (more…)
This chilled water unit is a new ammonia chiller. This unit is also unique in that it has no compressor. Instead, it uses the chemical properties of ammonia and heat from natural gas to condense the refrigerant which is ammonia. A chiller provides chilled water to a chilled water loop. (more…)
Air Source Chillers provide cool water for a hydronic piping system
How Hydronics Works | HVAC Technical for Consumers - Hydronics refers to using water and for chilled water, steam boilers and hot water boilers and other methods of transferring heat using water. A boiler or chiller is used to heat or cool the water and then the water is transferred through the hydronic piping loops to heat exchangers such as coils or baseboards where heat is transferred from the water to the air for heating and from the air to the water for cooling to provide comfort for people or a process.
Hydronics is very popular in commercial and industrial HVAC applications for heating and cooling occupants in large buildings and providing heating and cooling for equipment and machines including computers and servers. Basically in a nutshell hydronics uses water to move heat from one place to another.
Condenser Coil Repair - A crane is used here to lift a new condenser coil to a rooftop. The old condenser coil was leaking and could no longer be repaired. The process involved recovering all the refrigerant from the Trane rooftop unit. The rooftop unit was then partially disassembled and the old coil cut out from the system taking great care and planning to ensure the new coil could be retrofitted to the old refrigeration piping system. Good planning and skilled HVAC techs make the jobs go smoothly and make the replacement seem easy especially to the customer. (more…)
