NEED FOR ENERGY CONSERVATION

2

Now the entire world is craving for new and long lasting energy resource.

Fossil fuel resources are fast depleting and may not last more than few

centuries, besides not being very eco friendly.

Generation of heating, refrigerating and air conditioning utilities typically

account for40 to 70% of the electrical power consumed in various domestic,

commercial and industrial sectors.

Meeting the peak demand of electricity with limited generation and

transmission infrastructure has been a challenge.

What is MWE Air 2 Water HeatPump?

1.Compressor: This increases the pressure of the refrigerant so that it will accept the

maximum amount of heat from the air.

2.Condenser: Patented Coils that move heat to or from the outside air.

3.Evaporator: Patented Coils that move heat to or from the air inside the home.

4.Air handler: Fan that blows the air into the ducts of the home.

5.Reversing / Two way valve: Changes the heat pump from air conditioning to heating,

and vice versa. This is not part of the thermostat.

Air-Conditioning

A pure Air Conditioning can be provided.

Hot Air during low ambient temperature and Cold Air during high

ambient temperature is possible.

Space heating and Cooling is also possible by using Proprietarydesigned Radiant Panel or Fan coil units

Every Radiant Panel will have flow control knob so that Individual can

make himself comfortable.

Unused capacity of hot or cold water can circulate through insulated

pipe to other facility like office, Hostel, residential areas etc.

The system uses a high performance, patented Tube 2 Tube

technology to transfer the heat from Air to Water.

12/23

Radiant Cooling System

A radiant cooling system utilizes large surfaces, such as the floor, wall or ceiling.

Rooms are cooled by circulating water through embedded plastic tubes, excess

heat being absorbed by the surface.

Air change rates can be reduced to a minimum.

Radiant cooling system components can also be concealed, which enhances

the architectural concept and improves the rooms aesthetics.

Similarly to radiant heating, the temperature of the water circulating in the pipes

and room temperature are always close to one another, creating gentle,

comfortable cooling.

Cooling energy consumption is reduced, a key factor in obtaining moderate

energy bills.

It is a genuine benefit of the system that it allows you to install both heating and

cooling based on a single system 12

Conclusion

Techno-economic benefits are very attractive and provideshigh saving.

Generation of multiple hot and/or cold utilities simultaneouslygive added flexibility in matching the heating and coolingeffects

Attractive paybacks, in the range of 3 to 18 month, are

achieved in most of the cases with proper application

engineering.

Various opportunities for utilizing the surplus hot utility fordrying and dehumidifying using liquid desiccants


23/23

Revenue generated through recovered heat can more thanpay for the cost of operating the cold utility generators!

Increasing energy costs and raising concern forenvironmentheightens the need to go for heat recovery systems.

Installations have been working satisfactorily for several years,

in many cases without a service call.

Co-production of multiple utilities using a single system helpsreducing space requirement, initial cost and maintenance.

CO2 emissions are also reduced and electrical demand

reductions are also realized. Proper application engineeringcan ensure a Win-Win situation of simultaneously reducinginitial and operating cost.
