Large buildings with dozens of rooms have varying cooling and heating requirements, which can cause great strain to your HVAC system. These requirements can cause your chiller compressor to rapidly turn on and off.
Centralised air condition and heating systems commonly found in large buildings are often powered by a high-capacity HVAC system. Experts agree that this system is designed to handle the cooling or heating requirements of individual spaces in the building.
There are times, however, when the owners need to construct an extension to the building. This can add to the load of the HVAC, causing its compressor to turn on and off in an erratic manner. At this point, installing a buffer tank can be of great help.
When your loads and demands fluctuate, a buffer tank is necessary. Compressor valves modulate in response to the demands of different areas in the building, causing the temperature to go up and down. The idea of installing a buffer tank chilled water system is to control varying temperatures so that the chiller will have lesser stops and starts.
When there is a sudden drop in temperature and you have no buffer tank installed, your chiller will cycle off. It will quickly turn on and off to adjust to the varying temperature requirements of the entire area of the building. Whilst it is their function to do this, your chillers will experience unnecessary strain, which could shorten its service life.
Masterflow Solutions notes that a buffer tank can absorb the speedy drop in return temperature, allowing the chiller to continue operating at a regular pace.
Most chillers are not designed to handle large volumes of water. They are intended to be efficient in systems that have a minimal water volume. In a large building where chilling requirements vary, this can cause your compressor to experience excessive cycling. Buffer tanks guard your chillers against these sudden variations, allowing the system to run smoothly.
