Design of HVAC and ventilation systems

Thermal and refrigeration load calculations

Analysis of weather conditions

This service involves collecting and analyzing regional climate data including temperature, humidity, solar radiation, and wind direction. Design conditions are determined for different seasons and design parameters are calculated based on them. This analysis is used as the basis for all subsequent calculations.

Calculation of thermal and cooling loads

In this service, the building's thermal and cooling loads are calculated using specialized software. Factors such as heat transfer through walls, air infiltration, internal loads, and loads from equipment are accurately calculated. These calculations help determine the exact capacity of air conditioning systems.

Determining the required capacity of equipment

This service includes determining the optimal capacity of air conditioning equipment based on calculated loads. The capacity of chillers, boilers, air conditioners and other equipment is determined by taking into account the appropriate reliability factor. This capacity determination is done in a way that prevents equipment from becoming oversized and wasting energy.

Air conditioning system design

Choosing the type of air conditioning system
This service involves selecting the most optimal type of air conditioning system based on the project characteristics. Various options are compared, including VRF systems, chillers and fan coils, air handlers, and stand-alone systems. The final selection is made based on performance, cost, and flexibility criteria.
Ducting and piping design
In this service, the network of return air ducts and hot and cold water piping routes are designed. The dimensions of the ducts, the position of the valves, the insulation and the suspension system are carefully designed. This design is done in such a way that uniform air distribution and minimal pressure drop are ensured.
Control and automation system design
This service includes designing an intelligent control system to manage and optimize the performance of the air conditioning system. Sensors, thermostats, actuators and a central monitoring system are designed. This system is designed to allow independent temperature control in different zones.

Ventilation system design

Fresh air system design
This service includes designing a fresh air supply system in accordance with health standards. The amount of fresh air required for each space is calculated and the filtration and pre-conditioning system for the incoming air is designed. This design is done in such a way that the indoor air quality is maintained at the desired level.
Design of exhaust and local ventilation systems
In this service, exhaust systems are designed for specific spaces such as kitchens, bathrooms and laboratories. Industrial hoods, exhaust fans and local ventilation systems are designed to remove pollutants. This design is in such a way that the safety and hygiene of the workplace are guaranteed.
Energy recycling system design
In this service, the design of energy recovery systems from exhaust air is carried out. Various types of heat recovery systems, including rotary, plate and heat pipe, are examined and the most optimal option is selected. These systems help to significantly reduce energy consumption.
