Industrial Chillers- Air cooled chillers and Water cooled chillers

Prior to the discussion about chillers, let’s know what chillers stands for? A chiller is equipment that eliminates moist air against a liquid by a compressed vapor or absorption refrigeration cycle. These chillers are applicable to residential as well as industrial sectors.

Chillers basically available in the market are of two types.

  • Air cooled chillers
  • Water cooled chillers

Both the chillers are galvanized by dynamic motors, steam or gas appliances. These chillers consist of four units via which chilling stuffs passes through:

  • Evaporator: Chiller outturns frozen water/air in the evaporator where frozen refrigerant surpasses from the evaporator bundle. This refrigerant vaporizes as soon as warm air is being transmitted via the liquid. Again this frozen liquid is forced through the frozen water distribution unit into air handler unit.
  • Compressor: Evaporated refrigerant quits the evaporator and transmitted to the compressor unit, and then it is being compressed and converted into a high pressure, high temperature moisture. Then again quits the compressor section and moves to the condenser unit.
  • Condenser: Here warm refrigerant travels inside the tubes which consist of condenser coiled water. The moist air is transmitted to the water/air in order to transform into chilled liquid/air. Then the condensed air/water is stimulated to the cooling tower where moisture is transmitted from water to the surroundings.
  • Expansion valve: The refrigerant surpasses to the evaporator via the expansion valve. This valve manages the function of chilling. Here, refrigerant widens to a reduced pressure including reduced temperature. It passes near the evaporator tubes captivating the moisture of the frozen water which has been exchanged via the air handle unit and thereby completes its refrigeration cycle.

Principle on which air and water cooled chillers are based:

The working principle of a chiller can easily be understood. The source is packed with fluid, mainly water or an ethylene glycol/water mix, which is again recycled. That source is attached with desired machinery and then current is being equipped by the chiller. It’s all regulatory role is controlled by the manager/controller. A user can easily adjust the framework as per the situation desires such as temperature, flow and pressure. An internal filter is applied to eliminate the hazardous matter from the process.

Air cooled chillers and water cooled chillers in India is easily available on Cristopia cooling solutions.  In India, it is the top most firm of chilling devices enveloping both large and small scale cooling, heating and energy management solutions, such as Air Cooled & Water Cooled Screw Chillers, Scroll Chillers, and Thermal Energy Storage (TES) systems. Chilling technology is planted on heat transfer adopting the vapor compression refrigeration cycle.


VRV VRF VRW Air Conditioning Systems: A Perfect Way to Beat Heat

As the summer season approaches, lots of tension keeps on struggling in our mind how to make life smoother. Nowadays, technologies are advancing day by day to make life more enjoyable, adorable. HVAC manufacturers in India are one of such upcoming and subversive technology to worn out unbeatable summer. In the midst of air cooled technology VRV VRF VRW air conditioning systems in India are the most popular one. They are Eco-friendly, affordable rate, do not require much space, long term efficiency and easy for maintenance. Having plenty of advantages these technologies are being applied by almost all of the industries, offices, residential, malls and so on.

Cristopia cooling solutions in India began its journey since 1994, manufactures   HVAC technology of cooling devices inclusive of heating and energy management solutions, such as Air Cooled & Water Cooled Screw Chillers, Scroll Chillers, and Thermal Energy Storage (TES)

Variable refrigerant flow (VRF):
For cooling and heating mode a refrigerant is applied that permits an outward cooling system being linked with multiple fan-coil units (FCUs), which  is managed by its user. VRF technology functions at the desired scale in order to save the energy at limited capacity. It consists of respective indoor units as per heating or cooling is desired. On the other hand internal heat recovery is beneficial for compressor goods, saves up to 55% of energy. VRF is inherited with air conditioner inverter that boosts a DC inverter for backing of volatile motor speed linked with refrigerant flow besides depending upon on/off action.

VRV (Variable Refrigerant Volume):
VRV is the latest air cooling automation being applied by huge building besides be its offices, malls or theaters. The anterior part of the performing temperature has been enhanced from –15°C to – 20°C. This hi tech gadgets comprises of outdoor dimensions, perfect energy saving power, easy to implement, high efficiency and much more.

VRW air conditioning systems:
VRW air conditioning systems are self-operated with stable flow rate mangers which is achieved via regulatory blade with no friction which results in providing chilled airs. It comprises of low vibrations, easy to install in any duct of orientation, reduced leakage power, temperature resistance from -30°C to +100°C.
