How a Boiler, Fan Coil Unit, Air Handling Unit, and Pump Work Together in HVAC Heating

This video tutorial explains how different components of an HVAC heating system - Boiler, Fan Coil Unit, Air Handling Unit, and Pump - work together to provide heating.

Video Presentation

HVAC Heating Components

Boiler

The boiler heats the water which is circulated through the system.

Fan Coil Unit

The fan coil unit uses a fan to blow air over a coil heated by the hot water from the boiler.

Air Handling Unit

The air handling unit (AHU) conditions and circulates air as part of the HVAC system.

Pump

The pump circulates hot water from the boiler through the fan coil units and air handling units.

How They Work Together

The boiler heats water and the pump circulates this hot water through the system.
Hot water flows to the fan coil units, where the air is heated and distributed to the rooms.
In the air handling unit, the air is conditioned and circulated throughout the building.
The pump ensures a continuous flow of hot water, maintaining the heating cycle.

Conclusion

Understanding how the boiler, fan coil unit, air handling unit, and pump work together helps in efficient HVAC system design and maintenance.

The Importance of Preventive Maintenance in Modern Infrastructure

The Importance of Preventive Maintenance in Modern Infrastructure In today's fast-paced world, the reliability and efficiency of infrastructure are paramount. Preventive maintenance (PM) plays a crucial role in ensuring the longevity and optimal performance of mechanical, electrical, and plumbing (MEP) systems, as well as other critical components of buildings and industrial facilities. This article delves into the significance of preventive maintenance, its benefits, and best practices for implementing a robust PM program. Understanding Preventive Maintenance Preventive maintenance refers to the proactive approach of regularly scheduled inspections, servicing, and repairs of equipment and systems to prevent unexpected failures and costly downtime. Unlike reactive maintenance, which addresses issues after they occur, preventive maintenance aims to identify and mitigate potential problems before they escalate. The Benefits of Preventive Maintenance Increased Equipment Lifespan...
