Hvac System  

HVAC usually refers to the mechanical system of the building that provides heating, ventilation and/or coolingwithin a building or a premise. This includes air conditioners, furnaces, blower assembly, an evaporative coil, acompressor and compressor coil, thermostats, ductwork and filters which helps to distribute the conditioned airwithin a building.We follow a very stringent quality control system, where we ensure every raw material received and everymanufactured item is tested and approved as per the set quality norms. This ensures optimum performance of the equipments.

Chilled Water Systems

A chilled-water applied system uses chilled water to transport heat energy between the airside, chillers and the outdoors. These systems are more commonly found in large HVAC installations, given their efficiency advantages.

The components of the chiller (evaporator, compressor, an air- or water-cooled condenser, and expansion device) are often manufactured, assembled, and tested as a complete package within the factory. These packaged systems can reduce field labor, speed installation and improve reliability.

Alternatively, the components of the refrigeration loop may be selected separately. While water-cooled chillers are rarely installed as separate components, some air cooled chillers offer the flexibility of separating the components for installation in different locations. This allows the system design engineer to position the components where they best serve the space, acoustic, and maintenance requirements of the building owner..

Another benefit of a chilled-water applied system is refrigerant containment. Having the refrigeration equipment installed in a central location minimizes the potential for refrigerant leaks, simplifies refrigerant handling practices, and typically makes it easier to contain a leak if one does occur.

DX Systems

In a direct-expansion (DX) system, the evaporator is in direct contact with the air stream, so the cooling coil of the airside loop is also the evaporator of the refrigeration loop. The term “direct” refers to the position of the evaporator with respect to the airside loop.

The term "expansion" refers to the method used to introduce the refrigerant into the cooling coil. The liquid refrigerant passes through an expansion device (usually a valve) just before entering the cooling coil (the evaporator). This expansion device reduces the pressure and temperature of the refrigerant to the point where it is colder than the air passing through the coil.

The components of the DX unitary system refrigeration loop (evaporator, compressor, condenser, expansion device and even some unit controls) may be packaged together, which provides for factory assembly and testing of all components, including the electrical wiring, the refrigerant piping, and the controls. This is called a Packaged DX system.

One of the most common reasons for selecting a DX system, especially a packaged DX system, is that, in a smaller building, it frequently has a lower installed cost than a chilled-water system because it requires less field labor and has fewer materials to install. Packaged DX systems that use air-cooled condensers can be located on the roof of a building, in a small equipment room, or even within the perimeter wall of the
