Split Type ACs are usually the ones that are installed in High-rise buildings. Choosing the right type of Split AC is highly important for both commercial buildings and residential buildings alike; there should be a proper system of ventilation and cooling in order to get optimal comfort levels for all the residents in the building. This article will serve as a comprehensive guide for you in understanding what high-rise HVAC is, what kinds of split ACs are there for high-rise buildings, and How to install split AC in high-rise buildings.
What is High Rise HVAC Unit?
An HVAC unit designed for high-rise buildings is entirely different from the ACs used in fewer stories apartments. You must keep the temperature the same throughout the building for proper ventilation and the comfort of the residents. A well-planned HVAC unit is necessary to avoid uneven airflow throughout the building.
Types of Split ACs:
With evolving technology, many types of split Acs have come into the market:
Central Water-Cooled System: These are the most demanded split systems. These systems have a central cooling tower and a boiler, its water-sourced heat pump is responsible for optimal temperature throughout the building. Its drawback is that it is quite expensive to fix its water leakage.
Four-Pipe Water System: This system has two pipes for cooling and two pipes as a boiler for hot air which works simultaneously. This unit system is energy efficient as the chillers and boilers work simultaneously. It’s installation is expensive and it is difficult to measure the energy efficiency of each apartment.
VRF: Variable Refrigerant Flow (VRF) systems are advanced versions of multi-split ACs. They offer precise temperature control and high energy efficiency by adjusting the refrigerant flow according to the cooling demand.
Installation Procedure
Now let’s delve into the step that must be followed while installing split AC.
Pre-installing process: Preplanning is extremely necessary so you can efficiently mount the whole system according to your desired expectations. Consider the following factors:
Location Selection: Choose a location for an indoor unit that optimizes airflow and cooling distribution. Make sure the indoor unit is away from heat, direct sunlight, and other heat-generating sources.
Load Calculation: This is done so you can calculate the right AC capacity that is needed for a room. this includes calculating the room size, occupancy, and insulation.
Power Supply: If the building’s power supply is not adequate for the AC unit, take a separate electric circuit to accommodate the load.
Drainage: Figure out where the condensation water will go generated from the cooling process.
Outdoor Unit Placement: Select a location for putting outdoor units. The outdoor unit is usually placed on a balcony or a rooftop area. But make sure that the unit is placed where it is accessible for ac maintenance and doesn’t violate any building residency rules.
Gather the tools: Now that you’ve figured out the above-given steps, gather all the necessary tools such as screwdriver, drill, pipe cutter, level, and insulation materials.
2- Installation Steps:
Installation steps include:
Mounting the indoor unit: Take out your Level and check for the evenness of the unit that is placed on the wall. Then, drill holes for its bracket and hang the indoor unit there. Make sure that the unit is stable.
Electrical Connections: Connect the indoor unit’s electric wires to the power supply and double-check the insulation for safety purposes.
Refrigerant Piping: Cut the refrigerant copper pipes to the required length and then fit them to indoor and outdoor units using nuts. Check for the insulation to avoid condensation and maximize efficiency.
Install the outdoor unit: Now, place the outdoor unit at its designated place in the brackets. Check again to ensure that the unit is stable and secure.
Drainage: Connect the drainage pipe from the indoor unit to an outlet ensuring smooth flow.
Now, test the AC system to verify its functionality and cooling performance.
Takeaways
Even though these steps are given, you still cannot risk doing this by yourself. You must call a professional HVAC team who will do all the work for you. This article was to let you know about the basics of ‘how to install split ac in high rise building’. You still have to acquire professional help from certified and trained HVAC technicians for its installation.
