Classification of Hospital Electrical Loads

Before you calculate the power requirements for hospitals, remember that not every tool is worth running during the outage hours. In plaas daarvan, you should divide the appliances based on their usage terms. Here is the list of three different types of hospital loads.

Critical Loads

Critical Loads are the crucial appliances that are lifesaving for the patients. Without them, hospital facilities fail to provide the essential healthcare services. The primary goal is to run them at first.

Here are the examples of the critical loads available at the hospital.

• Ventilators
• Life-support equipment
• Operating room lighting
• Anesthesia machines
• Cardiac monitors
• Infusion pumps
• Emergency communication systems
• Fire alarm systems
• Nurse call systems

To run these loads, operators often use the UPS at first and then the Kragopwekkers later on to power the system as a whole.

Essential Loads

After critical loads, there come the essential loads. They are also crucial, but can bear a brief moment of power interruptions.

The list of essential loads in the hospital includes:

• HVAC systems for patient care areas
• Medical gas systems
• Elevators
• Pharmacy equipment
• Laboratory equipment
• Sterilization systems
• Water pumps

Non-essential Loads

Non-essential loads are not necessary for which you should supply energy. They can work without the emergency supply and wait for several hours until the power is restored.

The common examples of the non-essential loads are:

• Cafeterias
• Administrative offices
• Conference rooms
• Decorative lighting
• Public charging stations
• General office equipment

Calculation of Power Requirements for Hospitals and Healthcare Facilities

Before you calculate the power requirements, you must know what appliances are going to operate and the power of each appliance. We have divided the appliances based on their critical and non-essential loads.

Here is the list of different tools and the final power calculation. You can get an idea of the calculation according to our formula.

Stap 1: List Connected Appliances

Eerstens, you should know all the connected appliances. We have added the table of connected loads, including the number of appliances and the power consumption for each one.

Stap 2: Calculate Load

The overall load calculation is often the sum of the devices you use. Since we have used the following devices:

• MRI = 160 kW
• CT = 100 kW
• Ventilators = 30 kW
• Operating Rooms = 150 kW
• HVAC = 900 kW
• Beligting = 250 kW
• Laboratories = 220 kW
• Elevators = 108 kW

The total power calculation of these loads will be around 1,918 kW.

Stap 3: Apply Demand Factor

1918 kW is the total demand of all the appliances when run simultaneously. It rarely happens that all devices are running simultaneously.

Eerstens, there are a few devices that run simultaneously. Suppose 85% of the appliances run at the same time. The demand factor will be 0.85.

Maximum Demand= 1918 x 0.85 = 1,630 kW

Stap 4: Add Future Expansion

Do you want to expand the system in the future? It is typical that most people expand the system now or later on. Suppose you want to expand the system in the future.

Hiervoor, you should keep an extra safety capacity of 20-25%. Dus, the calculation will be:

Expansion Margin = 20%

Future Load = 1,630 × 1.20 = 1,956 kW

Stap 5: Kies Kragopwekker kapasiteit

Generators can be a good backup addition to your hospital system. Since the overall power requirements are 2MW, the power calculations for generators will be:

• 2 × 1000 kW generators (N+1 not included)
• 3 × 1000 kW generators (N+1 redundancy)
• 4 × 750 kW generators
• 5 × 500 kW generators

It depends on you whether you want to add redundancy to your system or not.
