Commercial and Residential Air Conditioning


One of our clients was having problems with their chiller tripping out during low load conditions. The site consists of 2 water-cooled chillers 1 of which is dedicated to low load conditions. The site has a couple of zones that require cooling when the rest of the site is calling for heating.

To overcome this problem, we have installed a plate heat exchanger connected between the building’s chilled water loop and the condenser water loop. With a couple of zones calling for cooling, we redirect the chilled water to circulate through the heat exchanger rather than the chillers, the condenser water pumps are then operated. The temperature and mass of the condenser water are more than enough to provide cooling where required for long periods of time during low load conditions.

The above system has solved the problem of the chiller constantly tripping and also provided considerable cost savings by not running the chiller and using free cooling.

Ultising dormant cooling capacity in a condenser water /cooling tower loop, via a heat exchanger, generating large energy savings.

Why choose commercial air conditioning services? 

Many homeowners choose commercial air conditioning services for a variety of reasons. One reason is that commercial AC unit are more powerful and efficient than residential units. They also have advanced features and technologies, such as programmable thermostats, that help to control the temperature in a home more effectively.

Types of commercial air conditioning 

Commercial air conditioning is a type of air conditioning system that is used in buildings and other structures to provide cooling and air circulation. There are several different types of commercial air conditioning systems, each with its own unique features and applications. 

These systems can be found in offices, schools, hospitals, malls, and many other types of buildings. They provide comfortable indoor temperatures and reduce the risk of health problems caused by poor air quality.

  • Refrigeration system:

These commercial air conditioning systems use a refrigerant to move heat through the system and are commonly found in industrial settings, such as food processing plants, pharmaceutical manufacturing facilities, and chemical plants. Refrigeration systems are more efficient than traditional air conditioners and can be used in applications where large amounts of heat or cold are needed, such as warehouses or greenhouses.

  • Hybrid system: 

Hybrid commercial air conditioning systems use both refrigeration and evaporative technologies to provide cooling and humidity control. These systems are often installed in high-humidity areas, such as hospitals or greenhouses, to help maintain optimal conditions indoors while reducing the amount of energy required to run the system. In some cases, hybrid systems can also be used to provide heating in colder climates during the winter months by using evaporative technology to extract moisture from the indoor air.

  • Evaporative cooling system:

This type of commercial air conditioning system uses evaporation to remove moisture from the indoor air, creating a cooler environment inside the building while reducing humidity levels in the surrounding area. These systems are commonly used in commercial kitchens and food preparation areas where high humidity levels can affect food quality and spoilage. Rooms can also be cooled using them.

How does commercial air conditioning work?

Commercial air conditioning systems use a variety of technologies to keep buildings and rooms cool. The most common type of air conditioning system is a split system, which uses outdoor and indoor units to distribute the cooling load. In the summertime, when temperatures are high outside, the outdoor unit will work to cool the building, while the indoor unit will work to keep the building’s occupants comfortable. In wintertime, when temperatures are low outside and the building is heated, the opposite happens: The indoor unit works to keep the building warm, while the outdoor unit works to cool the building.

What are the benefits of commercial air conditioning?

The benefits of air conditioning in commercial buildings include:

  • Reduced energy costs: Air conditioning uses electricity to cool the air, which reduces the amount of energy needed to maintain a comfortable temperature.
  • Improved employee productivity: Air conditioning can help to maintain stable indoor temperatures, which can reduce fatigue and increase worker efficiency.
  • Increased occupant comfort: Air conditioning can help to ensure that occupants are comfortable and can work effectively even in hot temperatures.
  • Reduced maintenance costs: Air conditioning requires less maintenance than traditional cooling systems, which can save money over time.

How do I choose the right commercial air cooling system for my business?
