HVAC SYSTEM:

A HVAC system is essentially a collection of different equipment types that are integrated together to provide heating, cooling, and indoor climate management. To keep things, products, or items placed in space preserved or to provide comfort to building or space inhabitants, HVAC systems incorporate mechanical, electrical, and I & C components.

Depending on the HVAC architecture, HVAC cooling systems may be built individually or in conjunction with HVAC heating systems. On an industrial scale, HVAC systems are also used to keep machinery functioning by regulating the temperature in the area where the machines are installed. Due to their many uses, HVAC water chillers have become crucial for any sector.

Basic HVAC System Components

The following fundamental parts or units may be found in an HVAC system.

  • heaters and chillers for HVAC water
  • If the chiller only produces chilled water, a hot water generator or furnace should be used.
  • Pumps for chilled water
  • pumps for cooling water
  • Control for the electrical power supply or a motor (MCC)
  • Towers for cooling
  • piping for condenser side water, chilled water, and cooling water
  • Valve for chilly and freezing sides of water
  • heating coils, cooling coils, and air handling units (AHUs) Coils
  • Ventilation system ducts (supply ducts and return ducts)
  • Thermostats and fan coil units
  • HVAC grills and diffusers
  • Various locations have HVAC controls (instrumentation & Control components) installed.
  • HVAC software for a building management system or HVAC control (BMS)


An HVAC system is assembled from the aforementioned parts.

As seen here, the operating concept of an HVAC system.

An HVAC water chiller creates chilled water in the background of the HVAC system, which is subsequently circulated throughout the building or area up to cooling coils in air handling units. According to HVAC design, blowers move air on cooling coils, which is then distributed into different areas of a room or building to provide comfort or preserve goods/items. Supply ducts are used to distribute air, and return ducts are used to collect air in air handling equipment. Pumps for chilled and cooling water use energy to maintain movement of the chilled and cooling water.

Additionally, HVAC Valves are added at various points in the pipe to facilitate HVAC system maintenance or for system management. Heating of the air can be accomplished using a furnace, hot water generator, or HVAC heat pump. In the winter, some industrial chillers also function as warmers. When in heating mode, heating coils replace cooling coils.

As the cost of heating and cooling a space or environment varies, HVAC systems may cost varying amounts for various uses. In order to avoid wasting millions of dollars by choosing the incorrect HVAC designer and contractor, your quest for inexpensive HVAC systems may only require a little investigation into the many types of HVAC systems and HVAC suppliers.
