Solar power ACs could be next big thing in Pakistan

[Geek]

With a serious power crisis and rising fuel prices, Pakistan’s industry appears to be looking toward alternative solutions to overcome its energy needs. The industry’s predicament also seems to have piqued the interest of foreign companies trying to find new markets for their eco-friendly, energy-efficient products.



One such example is the Chinese multinational Midea Commercial Air Conditioner (CAC), which has announced it will be distributing three new “green, energy-efficient” solutions for the Pakistani Heating, Ventilation and Air-conditioning (HVAC) industry.


The products, which fall under Midea’s MDV brand, include a solar-powered air-conditioner, a DC Inverter Variable Refrigerant Flow (VRF) system and a “Dual Storage Full Falling-Film Centrifugal Chiller.”


At a seminar in Islamabad on Wednesday, representatives of the Midea Group and its distributing partner in Pakistan, said the first shipment of the products is expected in Pakistan in mid-November.


“I think there is a growing demand for air-conditioners in Pakistan but at the same time there is a shortage of fuel and electricity,” said Dennis Lee, director Africa and South Asia of Midea CAC’s Global Sales. “So the Pakistani industry stands to benefit from energy-saving products.”


Assistant General Manager of Business Development at EES, Adnan Hamid, said energy has become a concern not just for Pakistan but also for the countries around the world. Hamid said there is a need to look toward alternative energy sources and environment-friendly solutions.


Beck Zhao, a Midea CAC representative, claimed MDV’s solar air-conditioner, when coupled with a two-panel DC inverter, could give energy savings of up to 78%. He added that the coefficient of performance for the company’s new chiller design is 7.06, which he said was higher than the efficiency of competitive designs.


Fahad Hasan, an engineer working with YH Associates, said 60% of electricity utilised in a building is used by HVAC systems. He said the need for energy-efficient industrial solutions is not only necessitated by the need for sustainability but also by scarcity of energy resources. Hasan said energy-efficient building design is “a wise investment,” not a “cost.”

Never trust seller until they have genuine neutral body certification of compliance with standard.

I think the building performance is also important, we must look into heat insulating materials in buiding construction. In today world countries are looking towards energy efficiency. Use polyurethane material in walls and roof, it is number one material for insulation. It will keep cooling in room for more time and heating in winter. Just experience it in meat points in metro cash and carry.

But with no cooling, all this insulation will keep HEAT in as well.

I don't understand what's so special about solar ACs? Can't we buy a regular AC and then buy solar setup separately and then connect those two?

the name is more exotic and modern

The whole country could be powered using solar for residential uses and the normal grid for industry but then the govt would lose it's main way of collecting taxes from awam, as soon as people go off grid govt won't get any tax/charges added to elec. bills which it knows majority of people have no choice but to pay. China is awash with cheap (govt subsidised) solar panels which they're having problems selling to Europe and us why didn't Nawaz inc mention this. There's a reason solar hasn't taken off in Pakistan it was the.ridiculous import tariffs on technology that were don't even have a domestic supplier off. I bet these crooks would be importing loads of solar panels if they actually bothered to pay they're electricity bills.

There is a small difference. If a company uses term Solar AC, it means they have built in DC motor(or built in inverter for AC Motor) in it and you do not need any external inverter. In other case for normal AC you need inverter which converts DC into AC.

:) Does not work like this at all. Insulated houses keep heat outside when its hot outside, and keep the heat inside when its cold outside! So basically it stops heat going across, as heat travel from hot to cold direction always!

It will be interesting to see efficiency of such AC that is powered by solar only, traditional compressor found in AC or Fridges requires huge amount of electricity power and to be fair, it will be impossible with home level solar panels to generate such kind of energy. Inverters only convert DC/AC signal form it doesnt increase the current (amperes)! So a water chiller /cooler kind of mechanism could be possible but highly unlikely they can able to run a traditional type of compressors with such ACs
