How Do Your Rooftop HVAC Units Work and the Importance of Guardrail for HVAC?

In many commercial applications, you can often find rooftop HVAC units to provide heating or cooling for any smaller buildings. Will a rooftop unit be right for your business?

How do such rooftop heating/cooling units work?

Similar to other heating and cooling equipment, rooftop HVAC units also function similarly, providing efficient comfort levels to occupants. These systems usually are connected to the ductwork of the building and can cool or heat the air passing through and then give out conditioned air all through the interios.

Air will enter a rooftop unit through the air hood available at its side. The air hood appears like an awning having an opening below it, which will allow air to enter and keep rain and snow out.

As air will pass through, dampers that operate inside for regulating airflow, and the air supply will pass through the filters of the system’ to remove contaminants.

Next, air will either be heated by a coil or heat exchanger or will be cooled by cooling coils (based on system configuration and mode of operation).

Lastly, the fan will circulate conditioned air all through the building’s ducts.

Con-form Group can offer the necessary roof guardrail systems that are available in modular form in the increment of 600mm. They are built to endure extreme and volatile weather conditions. They are offered as a levelled walkway meant for across roof slopes and also flat for any roof slopes.

Why often roof guardrails are mandatory?

Roof guardrails can be a highly effective way of managing and lessening some of the safety hazards that are involved in working at heights.

They are engineered for providing structural soundness, and can drastically reduce the potentially fatal falls and injuries.

Roof guardrails are normally used for providing protection when a person has to work within 2 metres of a falling edge. Generally, they are used across commercial, domestic, and industrial settings.

As an example, if an air conditioning unit will be installed on your roof edge, then it is going to be occasionally accessed for necessary servicing and maintenance. Roof guardrails will make this possible while at the same time providing requisite fall protection.

The requirements of the Australian guardrail usually state that guardrail systems have to be used under the law for:

  1. Housing construction work sites where any person can fall more than at least 3 metres
  2. Other construction work sites where there are the possibilities for a person to fall more than 2 metres
  3. Construction work on any roof or any partly completed roof surface having a slope not more than 26°.

Roof guardrails can ensure that you as well as your workers will meet the necessary requirements of Australian standards and regulations of height safety. This is very crucial for maximising safety and also minimising any risk in any work site.

Roof guardrail systems therefore should be installed by any qualified, experienced, and licensed professionals only. If you have any confusion about how to maintain full compliance with Australian standards, then consult any expert.
