There are a variety of HVAC systems available on the market today. Here are six of the most popular types of systems offered by HVAC companies in Pakistan.

Heating, ventilation, and air conditioning

Understanding the many ways to cool commercial spaces effectively is essential. Commercial HVAC Companies in Pakistan are becoming more comprehensive, providing an efficient way to cool rooms regardless of size. It depends on how much control you want over the system and the environment it’s running in.

Single split system

One of the most popular systems on the HVAC Companies in Pakistan are the Split HVAC systems. They are often used in small spaces such as offices, shops, and bakeries. It is widely used in renovations and new buildings because it is compact and easy to install. Most single split systems include:

  • An air conditioner that cools the refrigerant.
  • An oven that converts the refrigerant.
  • An evaporator coil that circulates the air.

Features

  • Affordable installation in small commercial spaces
  • The units are self-contained, so if one fails, the other systems will continue to function.
  • The system is energy saving

Negatives

  • It takes up space indoors and outdoors

Multi-split System

The multi-split system works like the single-split system. However, many indoor units are connected to one outdoor unit. It is a critical factor if your area is specific. Restaurants, retail stores, clinics, etc., often use this system because they share modular buildings. Installation is essential because multi-split systems can become submerged due to plumbing. Poor installation can compromise HVAC efficiency.

Features

  • The unit takes up less space.
  • The building does not require ductwork.
  • The appearance is preserved because there is only one unit

Negatives

  • Installation takes a long time.
  • When the outdoor unit goes down, all the system go down

VRF System

Variable refrigerant flow (VRF) systems are commonly used in medium to large spaces such as hotels, supermarkets, and office spaces. Two systems are available: heat pump and heat recovery.

A heat pump system provides heating or cooling, but not both simultaneously. This is the perfect solution, especially for open floor plans. HVAC systems can provide heating and cooling at the same time. This is convenient if you have a building divided into smaller rooms where individual comfort levels must be considered.

Features

  • The system is very reliable.
  • Installation is a quick process.
  • A small package that fits easily in challenging spaces

Negatives

  • Initial costs can be significant.
  • Humidity control has its limits.

CAV system

A constant air volume (CAV) system provides a constant flow of air as the temperature changes to ensure that the temperature is met throughout the space. Compressors operate continuously to maintain stable temperatures for long periods, making them ideal for areas such as hospitals, warehouses, and manufacturing plants.

CAV systems are often outdated. Instead, it has been replaced by a more modern system that offers better power consumption and superior zone control.

Features

  • Ideal for areas that require constant ventilation
  • Affordable to install

Negatives

  • Moisture sensitive
  • Due to the constant air volume, CAV systems have high energy costs.

VAV system

A variable air volume (VAV) system uses a compressor or a fan speed that varies based on room temperature. Compressors regulate the flow of refrigerant when spaces require different heating and cooling needs. Ensures that the temperature remains constant. These are reasonably new systems and are often chosen to replace older CAV systems as they can handle areas more effectively. VAV systems are energy efficient and are used in yards, office buildings, schools, and libraries.

Features:

  • Save energy costs
  • Works well with variable ventilation loads
  • Reasonable control of humidity and temperature

Negatives:

  • It is expensive to set up compared to many other systems
  • Requires a fan room, so a reasonable amount of space is required
  • Changes in pressure can make the system difficult to use in specific industries

Industrial Evaporative Cooler

Industrial evaporative coolers are not HVAC systems but provide the same cooling capabilities. The technology is different – hot, dry air is blown over a humid medium, which leads to evaporation. This evaporation cools the air, which can lower the overall temperature by 20 degrees or more, depending on the humidity level.
Evaporative coolers (called swamp coolers) can cool large areas. With fewer moving parts than traditional HVAC systems, they last longer and require less general maintenance.

Features

  • Does not require an airway.
  • Fixed units and movable units are available.
  • The system is easy to maintain.

Negatives

  • You should replace the media periodically.
  • Choose the right system.

How to select the right HVAC for your need?

First, you should consider all of your space needs. Knowing your area’s demand (and total volume) will help you explore your system more effectively.

You should also consider the cost of different units for installation and maintenance. Otherwise, getting your money back over time may become nearly impossible. If you choose a system to replace your current one, you must check what is out there. If you don’t have channels, selecting a plan that doesn’t require additional channels is a good idea. Installation costs can rise dramatically when ductwork is installed, which can break the bank.

Heating, ventilation, and air conditioning (HVAC) systems control the indoor environment. Commercial HVAC systems control temperature, humidity, ventilation, pressure, and smoke extraction. All three commercial HVAC systems use nearly any commercial facility, including office space, electrical distribution facilities, schools, storage facilities, and hotels. There are three types of plans: single split, multi-split, VRF, or VRV.

Benefits Of Single split system

As the name suggests, it is a mono-split system connecting one indoor and one outdoor unit. It is the most popular commercial HVAC system because it is affordable and suitable for small commercial properties.

The separate single system is very suitable for buildings with many small rooms. They allow the occupants of the room to control the internal environment independently. The different individual design of each room also does not affect the other rooms. One will still work if the other one fails.
One disadvantage of the single split system is that it can take up a lot of space because it requires pairing one indoor unit with one outdoor unit.

Benefits Of Multi-split system

The multi-split system does not occupy outdoor space and can better manage indoor units. This system allows multiple indoor units to be connected to one outdoor unit. The multi-section system can connect up to 10 systems to one outdoor unit, depending on the provider. With inverter technology, the compressor can operate at different speeds, and each indoor unit has its setting.

However, these systems are much more expensive to install than single-split systems because they require more plumbing to connect to each indoor unit.

Benefits Of VRF or VRV system

Variable Refrigerant Flow (VRF) or Variable Refrigerant (VRV) systems are more advanced commercial HVAC systems. VRF and VRV refer to the same system, and you can use the two acronyms interchangeably.

Similar to a multi-split system, a VRF or VRV system connects multiple indoor units to a single outdoor unit. These systems can also absorb heat from the air during the cooling process and redirect it to other parts of the facility that need heat. It is well suited for facilities that require dedicated heating and cooling across multiple areas, such as restaurants, office buildings, and factories.

VRF or VRV systems are more powerful than the other commercial HVAC systems mentioned above. Installation is quick and easy because it can meet the building’s most critical heating and cooling requirements. Although VRF and VRV systems have been in use for decades, they only became popular in the HVAC Companies in Pakistan in the past decade.

Installation Cost Analysis

The cost and installation fees for VRF or VRV systems are much higher than the other two types of systems. However, you can alleviate this concern by choosing appropriate HVAC Companies in Pakistan and hoping that a VRF or VRV system will save energy and increase its return on investment over time.

In general, every commercial HVAC system has its strengths and weaknesses. Before choosing the type to be installed in your facility, you must decide how to use it and what you need to achieve.
