5 reasons why you shouldn't use HVAC control systems for smoke ventilation

Posted by Conor Logan on 10/01/17 12:00

 


Smoke ventilation systems today require sophisticated control systems with highly complex sequences of operation. HVAC control systems could be seen as a viable solution, as they can be extremely flexible and offer a high degree of programmability. However, while they may be adequate for simple applications, there are a number of issues that mean they do not deliver on all the functionalities needed for more complex schemes.

Here are 5 reasons why:

Car Park Ventilation: How much attenuation should a design include?

Posted by Conor Logan on 31/05/16 12:00

As a designer working on a car park project, there are important considerations you will need to make about ventilation to ensure good air quality. Approved Document F (ADF) stipulates that sufficient ventilation must be provided to enclosed car parks to avoid an excessive build up of carbon monoxide (CO).

Choosing a cooling solution for a factory: Total Cost of Ownership

Posted by Paul Langford on 24/03/15 11:30

When choosing a cooling solution for a factory, it is important not to focus only on the initial investment, but to consider all the elements that make up the total cost of ownership (TCO) of the system.

Dual ventilation in residential common corridors: an interesting solution

Posted by Paul Compton on 26/11/13 11:30

Overheating in common corridors in residential buildings has become an increasingly vexing problem, which can be addressed by using a two-shaft smoke control system for day-to-day ventilation. One of the major issues is how many floors we can ventilate concurrently while still achieving a reasonable air flow balance between floors.

Factory cooling: have you considered the total cost of ownership?

Posted by Paul Langford on 29/10/13 11:27

If you are considering a cooling system for your factory, don’t make the mistake of focusing solely on the initial investment: consider the total cost of ownership of the system and what the critical elements which influence this are.

Natural ventilation is the solution for most heat intensive industries

Posted by Graeme Clark on 03/09/13 09:50

In the vast majority of cases, natural ventilation is the most effective and economic solution for factories housing production processes generating high levels of heat: 

• Natural ventilation is best suited to buildings where a large amount of internal heat is generated, since this leads to a high temperature gradient.

• If the building is tall, then this provides even more ideal conditions for natural ventilation to work at its most efficient, since this creates a good stack effect that makes moving air between different levels within the building easier.

Door magnets on shaft systems: An accident waiting to happen?

Posted by Paul Compton on 13/07/12 08:53

The purpose of smoke shaft systems is to ventilate lobbies and corridors in the case of fire allowing an easier escape or more effective fire fighting due to reduced smoke levels.  It is therefore necessary to provide a ventilator at each level of the building leading into the smoke shaft and to be positive that in an emergency each part of the solution will work as intended.

Why CFD is the answer when designing power plant ventilation schemes

Posted by Graeme Clark on 15/03/12 16:01

Power generation plants are complex building installations. When designing a ventilation scheme for this type of facility, the necessary calculations can’t be done on the basis of drawings alone. You need the right expertise in climate control and the right tools – a Computational Fluid Dynamics (CFD) analysis carried out by an expert is the best answer.
