Run around coils, commonly known as a split coil heat exchanger, are a key component in Heating, Ventilation, and Air Conditioning (HVAC) systems. These coils consist of two separate coils connected by a circulating pump and a piping loop. One coil is placed in the supply air stream to absorb heat, while the other coil is placed in the exhaust air stream to release that heat. The circulating pump facilitates the transfer of heat between the two coils, ensuring efficient energy exchange within the system.
The primary function of run around coils is to recover energy from the exhaust air stream and utilize it to preheat or precool the incoming supply air. This process helps to improve the overall energy efficiency of HVAC systems, leading to cost savings and reduced environmental impact. By harnessing the thermal energy that would otherwise be lost, run around coils play a crucial role in enhancing the sustainability of buildings and reducing their carbon footprint.
Run around coils in HVAC systems find extensive applications in various industrial and commercial settings due to their ability to provide efficient heat transfer between two air streams without direct mixing. One common application of run around coils is in air-handling units, where they help in recovering energy from the exhaust air stream to preheat or precool the incoming fresh air. This process aids in reducing the overall energy consumption of the HVAC system while maintaining a comfortable indoor environment. Additionally, run around coils are also utilized in heat recovery ventilation systems to improve indoor air quality and thermal comfort by exchanging heat between the outgoing and incoming air streams.
Another key application of run around coils in HVAC systems is in data centers, where maintaining optimal operating temperatures is crucial for the efficient functioning of electronic equipment. By incorporating run around coils into the HVAC system of data centers, the heat generated by the IT equipment can be effectively captured and transferred to the incoming chilled water supply, reducing the overall cooling load on the system.
