CHINT’s Insights into HVAC

Heating,  Ventilation  and  Air  Conditioning  Systems  (HVAC)  are mechanical  systems  that supply  or  remove  heat,  supply  or  remove humidity,  and  supply  outdoor  air  when required  within  a  building. Commercial buildings in the U.S. consume 39% of America’s energy and 68% of its electricity. They account for 38% of the carbon emissions in the air. Studies show that in a typical office building, its lighting, heating and cooling represent about 65% of total energy use. Heating and air conditioning systems account for 30 to 50 percent of a commercial.

business’s  annual  energy  bill.  If  a  building  uses  a  constant-volume  air handling system with no variable speed drives, the system runs at full speed all the time. Very significant energy savings (typically more than 50%)  can  be  achieved  by  using  electronic  sensors  and  variable frequency  motor  drives  (VFD)  controlled  by  power  electronics. Electronically  controlled  VFD  can  reduce  the  motor  speed  when  full flow is not required, therefore reducing the power and the electrical energy consumed.

HVAC systems operate over time and space, which means they

1.Need to change over day and over year in each room.

2.May need heating and cooling in different rooms of the same building.

3.Must meet diverse loads simultaneously.

i. Manufacturers & Integrators

Lower Costs:To gain the market share, HVAC system manufacturers and integrators must  be able  to  continuously  reduce  the  costs  of  every  single component.

Easy Installation:Installation  takes  time  and  time  means  money.  Easy  installation  each component will save a lot for HVAC manufacturers and integrators.

High Reliability: HVAC systems are very crucial for our life and work. Therefore, the reliability must be guaranteed.

Quick Response: HVAC system manufacturers and integrators need the timely responsefrom their suppliers in case there are some problems. Also, HVAC system manufacturers and integrators need the support from different vendors to shorten the time to market

Customization:Different manufacturers have different requirements. HVAC system manufacturers  reasonably  hope  that  their  suppliers  would  like  to customize  products  for them  under  some  circumstances.  Such customization can tangibly optimize the performance.

Partnership: HVAC manufacturers, especially those successful manufacturers want to establish and maintain long-term partnership with their suppliers. Their ideal partners must be equally successful.

ii.End Users

Energy Efficiency: As HVAC system accounts for the majority of the energy consumption of a building, the end users must pay attention to the energy efficiency of the system they are going to adopt.

Little Maintenance: Maintenance, as a component of operational costs, must be cut to reduce the total cost of ownership

Balanced Functionalities and Price: End users of HVAC system are in earnest for the balance between functionalities and price. HVAC system manufacturers must be aware of this and therefore take concrete measures.

3.Chiller :
A chiller is a machine that removes heat from liquid via a vapor-compression or absorption refrigeration cycle. The liquid can then be circulated through a heat exchanger to cool air or equipment as required. We provide different control solutions for chillers.
