What To Consider When Designing A New HVAC System?

The HVAC (Heating, Ventilation, and Air Conditioning) system is one of the most important factors in making a building's interior pleasant and productive. This system architecture is the backbone of indoor climate control in every building type. It's not only about keeping things warm or cool; it's also about making sure the air is clean, the lights stay on, and nobody gets sick. 

When constructing a new HVAC system, there are a number of important considerations that will be discussed in this blog. Each stage is essential in developing a system that satisfies your immediate demands and stands the test of time, from determining the amount of space needed to installing the necessary equipment and considering the effects on the environment. Let's dive in and learn everything you need to know to get an HVAC system that meets your needs.

Types Of HVAC Systems 

Learning about the many kinds of HVAC systems and the advantages provided by each unit should come first in designing your system. The following are types of HVAC:

Traditional Split Systems

When it comes to commercial buildings, split systems are by far the most common form of air conditioning. Split refers to the fact that there are two main parts to the structure of a split system. A thermostat may be used to control the heating and cooling systems separately or together.

The heating component of a split system is often a boiler, and the cooling component is the more commonplace central air conditioner. In addition, conventional split-system HVAC units use a ducting and venting system that efficiently distributes conditioned air throughout the structure. The installation of ducts is unnecessary with ductless split systems.

The benefits of split systems include low initial investment, high flexibility, and low running costs (when properly tuned).

Hybrid Split System

Hybrid systems are very like split systems; the main distinction is that you get to pick between two different kinds of heating. With a hybrid system, you may adjust the temperature of a business building's heating using a regular boiler and a heat pump.

The heat pump also extracts heat, making it possible for the HVAC system to include a cooling component. Hybrid systems are more eco-friendly and provide you more control over your heating costs and carbon footprint by allowing you to adjust the temperature from a single location.

Hybrid systems, like split systems, can install a duct and vent system for efficient and uniform heating of a commercial building.

A heat pump and a furnace are both used in a hybrid split system. The heat pump is fueled by electricity. This gives you more control over your heating expenses by allowing you to tailor your heating needs to either unit.

In the warmer months, the heat pump can remove excess heat from inside spaces to serve as a cooling system. A hybrid system functions like a standard split system, with conventional ducts and thermostats.

Ductless Split Systems

A ductless system is an alternate solution that can be utilised where conventional duct systems cannot be installed. A ductless system employs separate units to perform the functions of a central heating and cooling system. These systems are built into the walls or ceilings of the desired space by trained professionals.

A ductless split system is a fantastic option for buildings that have different units, such as apartment complexes and hotels, because it allows each unit to have its thermostat that can be used to manage the temperature.

Geothermal Systems

Instead of using fossil fuels, which can be expensive, geothermal HVAC systems heat and cool the building directly from the earth. Here, fluid is pumped through a network of pipes in the ground using an electric pump. In the winter, the heat from the rock, soil, and water is transferred to the fluid, which is then used to heat your home's air via a heat exchanger. During the warmer months, the fluid is able to draw heat from the atmosphere and release it deep underground.

Geothermal systems are up to four times more energy efficient than conventional systems because of this naturally helped process.

Packaged Systems

A packaged system is one that integrates all of the essential components for heating and cooling into a single chassis. Because of its compact design, the system is an excellent choice for use in tight quarters that cannot house all of the individual components required by split systems. These devices are installed by trained professionals outside, and they make use of a blower to bring air into and out of the system.

What Are The Most Common HVAC Systems?

The standard and hybrid split systems are the two most frequent types of HVAC units. The most practical and affordable HVAC setup is a conventional split system. You don't have to worry about special conditions to use these units, and you barely need to alter your current ducting to put in new parts.

Hybrid systems are common because they function similarly to conventional systems while offering the convenience of two different kinds of heat. You can select the most cost-effective heat source depending on your energy needs and budget.

Ductwork

The ductwork in your HVAC system is crucial to maintaining consistent temperatures throughout your home. It is important to properly size ducts for the area they serve in order to minimise the temperature drop of conditioned air as it travels through the ducts.

The air's speed and direction will also be affected by its length and the precise path. You may not be as cosy as you would like if your home's ductwork has tight turns, unusual angles, or long runs.

Code Compliance

Building regulations control every level of government, from the municipal to the federal. Your heating system's design will need to comply with the codes established by the various regulatory authorities responsible for your region.

If the installers of your heating system do not construct it in accordance with the applicable building codes, you could be subject to fines and have difficulty selling your property in the future. Neither of these is the best possible scenario for a homeowner.

Ventilation

Ventilation is essential to the comfort of your house as well as your overall health. Inadequate ventilation can lead to poor indoor air quality, which, in turn, can cause various health problems, such as trouble sleeping, an increase in the severity of allergy symptoms, or an attack brought on by asthma.

The importance of proper ventilation in preventing mould and moisture buildup is often overlooked by house and business owners. Prevention is always preferable because of the health risks and high removal costs associated with mould and excess moisture. If you want to keep mould and moisture out of your home, it's important that the fitters know how to vent the heating system correctly.

Sizing

It's not as simple as "bigger is better" when determining the optimal size of your equipment. An oversized furnace will heat the room quickly, which is less desirable than it may sound. Because of this, the machinery has more wear and tear because it cycles on and off more often (when it reaches a certain temperature).

If your home's furnace is inadequate for the size, it will keep running in vain, never quite getting the rooms to the temperature you want. More fuel is consumed, increasing your overall costs.

How should you go about making decisions on the design of your heating system? The ACCA provides recommendations for load estimations. They built this instruction on the most accurate information available regarding the installation of heating systems, and it also takes into account any recent technological advancements.

When it comes to the design of heating systems and the calculations of load, you'll want to have a vast knowledge base of the facts and figures the industry uses. Do not put yourself in danger by requesting that your installers put in a system that is either too big or too little. 

Key Considerations for Building an HVAC System for a Business

If you're looking for someone to design an HVAC system for your high rise, look no further; no one has ever come close to matching our quality. We take many factors into account when designing custom HVAC (heating, ventilation, and air conditioning) systems for our clients.

Energy efficiency, passenger comfort, and system performance as a whole are all factors that can be significantly affected by HVAC system design. These systems are vital to ensuring that the inside of a building remains a pleasant and healthy place to work or live. Let's start with the most important factors:

Cooling And Heating comfort

Making sure your employees and clients are relaxed is essential. Your employees will be more productive year-round if they save time layering up or down or coming up with creative solutions to maintain a comfortable temperature in the workplace.

Still, if they have to constantly adjust the temperature by opening and closing windows and vents, the efficiency of the HVAC system will suffer. Think about whether you anticipate a greater demand for heating than cooling, or vice versa, or about the same.

Building Layout And Size 

The HVAC system's design is heavily reliant on the building's size and layout. The load calculations needed to comprehend the capacity requirements of the system are determined by the total floor space, number of floors, and room configurations. Proper sizing and zoning of the HVAC system relies on precise measurements and assessments of the building's characteristics, both of which our technicians are well-versed in performing.

Energy Efficiency

When designing an HVAC system, it is essential to prioritise energy efficiency. An energy-efficient system saves money and has less of an effect on the environment. The energy efficiency of a system is affected by a number of factors.

These include the equipment choice, insulation, ducting design, and control systems. To achieve the greatest possible reduction in energy use, it is essential to use correctly sized equipment, high-efficiency parts, and intelligent controls.

The designers of heating, ventilation, and air conditioning systems are responsible for incorporating energy efficiency into their plans. A system that is efficient with energy helps the building to maintain a comfortable temperature throughout the year, regardless of the season.

This reduces the commercial building's monthly energy expense by decreasing the air conditioner's energy consumption. To ensure the best performance from an HVAC system, a building's insulation should be optimised whenever possible. The environment also benefits from energy efficiency, so your business may tout its green credentials.

Air Quality Control

The health of a building's occupants is directly related to the quality of the air inside it. Indoor air quality is determined by the presence or absence of ventilation, filtration, and humidity control. Incorporating effective air filtration, fresh air consumption, and humidity regulatory systems into the design of HVAC systems can achieve high air quality and minimal pollution, allergens, and toxins.

No matter what kind of business you run, maintaining good indoor air quality should be a priority. Using photocopiers and printers in an office environment results in the release of ozone and other pollutants.

At the same time, volatile organic compounds from paints and solvents could present a more challenging chemical environment in a warehouse or factory setting. Your heating, ventilation, and air-conditioning system needs to handle not only the size of the space you have but also the different kinds of pollutants found there.

Requirements For Maintenance

Designing HVAC systems so that they are easy to maintain and service is often underestimated but is crucial. Fonko designs systems so filters, equipment, and other parts can all be accessed with relative ease, making routine maintenance much less hassle. Downtime and maintenance expenses can be reduced with well-thought-out equipment layouts and unobstructed service lines.

Regular maintenance is something that every HVAC system needs in order to continue functioning effectively and efficiently. Check to see how frequently you will need to conduct a full service or change the filters – this might vary depending on the manufacturer's warranty – as these will be included in your monthly and annual maintenance fees. 

Cost-Effectiveness

Cost is a major consideration for any commercial enterprise, but more so for such a massive undertaking. The goal of an HVAC designer is to maximise efficiency while minimising expenses without sacrificing the opportunity to save money in the long run (by, say, investing in more energy-efficient equipment).

If you want to save money in the long run, you shouldn't just order the cheapest air conditioner you can find; instead, you should design a system that is unique to your needs and efficient enough to pay for itself over time.

Occupant Comfort

A heating, ventilation, and air conditioning system's principal function is to make the building's occupants feel at ease. Controlling the temperature, ensuring adequate air circulation, and minimising ambient noise are three important aspects that contribute to occupant comfort.

To attain the highest possible levels of comfort across the entire building, there is a need to install machinery of the appropriate size, ductwork that has been thoughtfully built, zoning systems, and components that reduce noise.

Cooling Loads

When designing, building, and optimising a cooling system, designers must take into account cooling loads. A building's cooling load is the heat that the air conditioning system must remove from the structure in a particular amount of time.

An air conditioning system needs to handle a high cooling load to effectively cool large buildings, buildings that retain more heat, and buildings that need to be kept cooler than usual. If not, the building will be efficient and comfortable to be in during the warmer months.

Conclusion 

The HVAC (Heating, Ventilation, and Air Conditioning) system is crucial for a building's interior comfort and productivity. It plays a vital role in indoor climate control, ensuring clean air, light, and safety. When designing an HVAC system, it is essential to consider factors such as space requirements, equipment installation, and environmental impact.

There are several types of HVAC systems, including traditional split systems, hybrid split systems, ductless split systems, geothermal systems, and packaged systems. Traditional split systems have two main parts: a boiler and a heat pump, with a thermostat controlling heating and cooling separately or together.

Hybrid systems offer two different types of heating, allowing for more flexibility and cost control. Ductless systems use separate units to perform central heating and cooling functions, making them ideal for buildings with multiple units.

Geothermal systems heat and cool buildings directly from the earth, using an electric pump to transfer heat from rocks, soil, and water to the fluid. Packaged systems integrate all essential components into a single chassis, making them ideal for tight spaces.

Conventional split systems are the most practical and affordable, while hybrid systems offer the convenience of two different types of heat. Proper ductwork is essential for maintaining consistent temperatures and minimizing temperature drop. Building regulations control heating systems, and failure to comply can result in fines and difficulty in selling property.

Ventilation is essential for indoor air quality and health, as inadequate ventilation can lead to poor indoor air quality and health problems. Proper ventilation is crucial for preventing mold and moisture buildup, which can be costly and health-threatening. Proper ventilation is essential for maintaining a comfortable home and preventing health risks associated with excess moisture.

The optimal size of equipment for a heating system is crucial for ensuring comfort and efficiency in the building. Oversized furnaces can heat rooms quickly, leading to more wear and tear and increased costs. To make informed decisions on heating system design, consult the ACCA's load estimation guidelines and consider the latest technological advancements.

When designing an HVAC system for a business, consider factors such as cooling and heating comfort, building layout and size, energy efficiency, air quality control, maintenance requirements, cost-effectiveness, occupant comfort, and cooling loads. Ensuring employees and clients are relaxed and comfortable is essential for productivity and overall health. Building layout and size also play a role in the system's capacity requirements.

Energy efficiency is crucial for maintaining a comfortable temperature throughout the year, reducing monthly energy expenses and promoting green credentials. Incorporating effective air filtration, fresh air consumption, and humidity control into the design can help achieve high air quality and minimize pollution, allergens, and toxins.

Maintenance requirements are essential for HVAC systems, with Fonko designing systems that allow easy access to filters, equipment, and other parts, reducing downtime and maintenance expenses. Regular maintenance is necessary to ensure the system continues to function effectively and efficiently.

Cost-effectiveness is another important consideration for commercial enterprises. The goal is to maximize efficiency while minimizing expenses without sacrificing long-term savings. A unique and efficient HVAC system should be designed to pay for itself over time.

Occupant comfort is also crucial, with appropriate machinery, thoughtfully built ductwork, zoning systems, and noise-reducing components contributing to the highest levels of comfort across the entire building.
