For centralized air conditioning system, normally there are 2 types of device that discharge or blow the cooled air to the air conditioned space or room, the fan coil units (FCU) and air handling units (AHU). What the different between the fan coil unit and air handling unit? And it application? Actually at the first [...]

We as an M&E consultant engineer will recommend different types of air conditioning systems depending on the applications, budget available and future operation cost. The most commonly used air conditioning units is split air conditioners as the initial cost is the cheapest among all type of air conditioner.
Below are the various type of the air [...]

Most of the consultant design the air conditioning cooling capacity based on how big is that area and multiply by the selected cooling capacity per ft^2. However, for some of the room (i.e UPS room, medical waste room, computer server room, lifts motor room and etc), the following items shall be considered:

The heat dispersion from [...]

Air Conditioning Design: Sizing of Air Conditioning Circulating Pump
Once we know the total flow rate required for the Chilled Water air conditioning system as mention in my previous post How to Size Water Cold or Chilled Water Flow Rate, next step is to design or select the circulating pump based on the designed flow rate.
Circulating [...]

As mentioned in my previous post CO2 Suppression System, CO2 system design mainly related on the sizing of the CO2 cylinder or required CO2 volume to extinguish the fire at the protected space.
Example:
Generator Set Room with Room dimension of: 3.9m (H) x 2.9m (W) x 7.9m (L)
1st Step: Determine the Hazard Group
Difference hazard group (i.e. [...]
