Question 9

What are the different types of commercial HVAC systems?

Accepted Answer

There are many different types of commercial HVAC systems available today. They all serve to provide heat and cooling for commercial buildings. Here are some of the more common types:

Radiators: These are large metal boxes filled with hot water or steam. They are used to warm up rooms and spaces.

Supply Fans: This fan blows air into the room through vents.

Return Fans: This is the opposite of the supply fans. It pulls air out of the space and pushes it back into the ductwork.

Duct Work: This is the pipe that carries air throughout the building.

Air Handling Units (AHU): This box houses the blower motor and filters.

Blowers: This is what moves the air around.

Refrigeration: This is how we cool things down.

Condensing Unit: This unit converts the refrigerant gas to liquid form.

Evaporator Coil: This is the coil inside the condensing unit that turns the refrigerant gas into liquid form.

Evaporation Chamber: This is where the vaporized refrigerant goes when it leaves the evaporator coil.

Capacitor Heater: This is the device that heats the compressor oil.

Compressor: This is the machine that compresses the refrigerant gas.

Question 10

What are the three main types of refrigeration systems that are used in commercial building HVAC systems?

Accepted Answer

In most cases, commercial HVAC systems use three main types of refrigeration units used in commercial HVAC systems:

1. The traditional split-system air conditioning unit.

2. The newer variable speed air conditioning unit.

3. The newer variable refrigerant flow air conditioning unit.

That depends on the size of your building and its location. The split system might be best if you have a small office building. For medium-sized businesses, the variable-speed air conditioner may be better suited. Finally, the variable refrigerant flow air conditioner is the right choice if you have a more significant business.

Question 11

Which one should I use?

Accepted Answer

That depends on the size of your building and its location. The split system might be best if you have a small office building. For medium-sized businesses, the variable-speed air conditioner may be better suited. Finally, the variable refrigerant flow air conditioner is the right choice if you have a more significant business.

Question 12

What is the difference between residential and commercial HVAC?

Accepted Answer

A commercial HVAC system's design is different from a home HVAC system. Commercial HVAC systems are much bigger, more heavy-duty, and require more energy. They also need to be able to handle extreme weather conditions like high humidity and low temperatures.

The two main differences between residential and commercial HVAC systems are size and weight. Residential HVAC systems are usually smaller and lighter, weighing less than 500 pounds and measuring approximately 2 feet wide by 5 feet tall.

A commercial HVAC system will weigh at least 1,000 pounds and can easily exceed 2,000 pounds. In addition, they will generally be about 4 feet wide by 8 feet tall.

Question 13

How often do I need to service my commercial HVAC system?

Accepted Answer

Many different factors determine how often you should service your commercial HVAC system. Some of these include:

How old is the equipment?
What's the type of equipment in use?
Is the equipment located outdoors or indoors?
Does the equipment run 24 hours a day?
Are there any particular circumstances, such as extreme heat or cold?
Do you have an emergency generator?
How large is the building?

If you answered yes to all of the above questions, then you should schedule regular maintenance for your commercial HVAC equipment. It's essential to check the equipment every month, especially during summer.
