HVAC (Heating, Ventilation, and Air Conditioning) systems are essential in regulating indoor air quality and temperature in residential, commercial, and industrial buildings. These systems provide comfortable indoor environments, especially during extreme weather conditions. HVAC systems also help improve indoor air quality by controlling the circulation of air and filtering out pollutants, such as dust, smoke, and allergens.
There are different types of HVAC systems, such as central heating and cooling systems, split systems, packaged systems, and ductless mini-split systems. Central heating and cooling systems are the most common type of HVAC system and are typically used in larger buildings. They consist of a central unit that heats or cools the air and a network of ducts that distribute the conditioned air throughout the building. Split systems, on the other hand, have separate indoor and outdoor units and are commonly used in smaller buildings. Packaged systems contain all components in a single cabinet and are ideal for buildings with limited space. Ductless mini-split systems are similar to split systems but do not require ducts, making them ideal for renovations or buildings where ductwork installation is not feasible.
HVAC systems play a critical role in providing comfortable and healthy indoor environments in various types of buildings. Properly designed, installed, and maintained HVAC systems can also help reduce energy consumption, lower utility bills, and improve the overall sustainability of buildings.
Our team of engineers is well experience in designing HVAC systems according to industry standard codes such as ASHREA.
In Ontario it is mandated to perform Heat Loss Gain Calculations per OBC. The calculations serve as a crucial determinant of a home’s heating and cooling requirements by measuring the energy needed to keep it warm in winter and cool in summer.These calculations form an integral part of HVAC Design, serving as the foundation for selecting the right HVAC system.
Precise calculations and analysis are indispensable for accurate system component sizing. The correct sizing of these components significantly affects comfort, efficiency, and reliability.
An oversized HVAC system results in reduced efficiency, soaring operating costs, and an adverse impact on climate control within the home. Thus, proper equipment sizing is crucial to ensure the system’s efficiency and reliability over the short and long term.
Several factors directly influence Heat Loss/Gain Calculations, including the home’s exposure and orientation, structure composition, external and internal shading, infiltration, and soil conductivity.
Dust control systems are very important at houses and essentially required at facilities where dust and airborne particles are generated during various processes. Dust can pose a significant health risk causing respiratory issues and other health problems. Therefore, implementing an effective dust control system is critical to minimize the risk of exposure to harmful dust particles.
There are different types of dust control systems, and each system has its own unique features and advantages. Dust collectors are one of the most common types of dust control systems, which use filters to capture and remove dust particles from the air. The dust particles are collected in a hopper or bin, where they can be disposed of safely. Dust collectors are particularly useful in industries such as metalworking, woodworking, and mining.
Wet scrubbers are another type of dust control system that uses water or other liquids to capture and remove dust particles. Wet scrubbers work by spraying water onto the dust particles to weigh them down and capture them. The scrubbed air is then passed through a mist eliminator to remove any remaining water droplets before being released into the atmosphere. Wet scrubbers are particularly effective in removing larger particles that may be difficult to capture using other methods. They are commonly used in industries such as cement manufacturing, power generation, and chemical processing.
Our mechanical engineering team has extensive experience in designing effective dust control systems that comply with industry standards and regulations where required. We work closely with our clients to understand their specific needs and develop customized solutions that effectively capture and remove dust from the air, improving air quality and reducing the risk of accidents.
Fume extraction systems are designed to capture and remove harmful fumes generated during industrial processes, such as welding, soldering, and chemical processing or during cooking at restaurants. Fumes can pose significant health risks to workers, causing respiratory issues and other health problems and can also lead to fires if not properly removed. Fume extraction systems help minimize the risk of exposure to harmful fumes by capturing and removing them from the air, creating a safer and healthier work environment.
There are different types of fume extraction systems, and each system has its own unique features and advantages. One of the most common types of fume extraction systems is local exhaust ventilation (LEV), which captures fumes at the source using a hood or nozzle. The fumes are then transported through a duct system to a filter or scrubber where they are removed from the air. LEV systems are particularly effective in industries such as welding, where fumes are generated at a specific location.
Another type of fume extraction system is the use of industrial air cleaners. Industrial air cleaners work by circulating the air in the workspace through a filter that captures and removes fumes and other airborne particles. They are commonly used in industries such as painting, woodworking, and chemical processing.
In addition to local exhaust ventilation and industrial air cleaners, other fume extraction systems include portable fume extractors, fume extraction arms, and downdraft tables. Portable fume extractors are mobile units that can be moved from one location to another and are particularly useful in areas where fixed fume extraction systems are not practical.
Our team of mechanical engineers can design custom fume extraction systems that effectively capture and remove hazardous fumes from the air that are efficient, effective, and compliant with relevant regulations.
Pipe sizing is an essential aspect of plumbing design that ensures efficient and effective water distribution throughout a building or a facility. Proper pipe sizing helps maintain adequate water pressure and flow rates to meet the demands of various fixtures and appliances. The goal of pipe sizing is to minimize pressure drops and reduce the risk of leaks, while also ensuring that the system operates within safe pressure limits.
The size of a pipe is determined based on various factors, such as the flow rate, the pressure of the water supply, and the distance between the source and the fixture or appliance. Different pipe materials have different flow capacities, and it’s essential to select the right pipe size and material to ensure optimal performance and longevity of the plumbing system. Factors such as the number of fixtures and the peak demand of water use also play a role in pipe sizing.
To size pipes correctly, various tools and resources are used such as the National Standard Plumbing Code, International Plumbing Code, and various software programs. These tools help ensure that the pipe sizing meets all safety and building code requirements while also achieving optimal water flow rates and pressure levels. Proper pipe sizing also helps minimize energy waste by reducing the amount of water that needs to be heated and circulated, resulting in lower utility bills and a more environmentally friendly plumbing system.
Our team of mechanical engineers is experienced in designing piping systems that maximize flow and minimize friction loss, resulting in lower operating costs and longer system life. We use industry-standard software and best practices to size and design pipes and fixtures for residential, commercial and industrial applications.
