energy efficient airconditioning

[Darshi Dhaliwal]

No doubt, air- conditioning is a necessity in Thailand due to its hot and humid climate throughout the year. But it is surprising that there is not a care about the energy being used due to overseeing and use of off the shelf split air conditioners.
Most of the air- cons sold in the shops have EER (Energy Efficiency Ratio) as low as 7 btu/watt or less. Small apartments may use 3 to 5 air cons of 18000 BTU capacity each requiring a connected load exceeding 8 to 13 KW per apartment.
It is amazing that a country that is importing energy for its industrial production, has overlooked energy conservation opportunity at home .
Demand Side Management is a now a well established technique to save energy for the future generations. It will be benefit Thailand to make use of this available opportunity to save a considerable amount of electrical power.

You pointed well about the machine itself but in my view more attention must be paid in the structure and heat prevention adoption of building and house where need air-conditioning.
single wall, uninsulated roof or visor structure against sun ray bombardment are the major consumers of electricity.
The governmental standard housing design is totally missing from such basic engineering consideration.
It must be attended immediately.

Are you joking? The majority of buildings and houses in Thailand are single wall and mostly of brick, concrete, and stucco wall. Central A/C system and or zone control system is as rare as pink elephant. Many of these modular A/C units are improperly installed and even in the full sun. Many of these old units do not even have auto shut-off or setting for temperature. Most people do not even know how to use their A/C system. Once they turned on the units, the units would continue to blow until someone turning off the units.

Is there an energy efficiency oeganisation in Bangkok ?
I feel many locations in Thailand can benifit from indirect evaporative cooling .The systems can save almost 80% or more energy .
Local bus transport is another important area that need attention .
As many buses are airconditioned by an independent engine for running the air con,the city has very high pollution levels .
The city should examine use of desiccant cooling using waste heat from the bus engine.May be some university can take up the project. I will be glad to help

Cycling enables me to acclimate to the humidity in Thailand. A ceiling fan, to me, is better than AC; but then I am a non-smoking, non-drinking vegetarian. I think officials/leaders could set a better example if they tried to acclimate with Thailand's climate rather than fight against it.

WE ARE TALKING ABOUT MOSTLY THE PROBLEM WITHIN BANGKOK AND OTHER CITIES. MAJORITY OF HOUSES IN THE RURAL THAILAND DO NOT HAVE A/C OR CEILING FANS. PEOPLE GENERALLY USE PORTABLE FANS. BUT IN THE COUNTRYSIDE, THE TEMPERATURE IS MUCH COOLER THAN IN THE CITY. MOSQUITO NET IS MORE IMPORTANT THAN FAN OR A/C.

SOUND VERY GOOD. WHAT IS YOUR EDUCATIONAL DEGREE LEVEL? THERE IS AN ASIAN SCIENCE AND TECHNOLOGY UNIVERSITY AT RANGSIT CAMPUS IN BANGKOK NEXT TO THAMMASART UNIVERSITY RANGSIT CAMPUS. THERE ARE MANY INTERNATIONAL SCIENCE STUDENTS STUDYING THERE AND MANY SOUTH ASIANS TOO. I HAVE A FRIEND WHO TEACH AT THAMMASART RANGSIT CAMPUS AND AT KMIT CAMPUS. THERE ARE BUS MANUFACTURING COMPANIES IN THAILAND THAT USING IMPORTED ENGINES AND EQUIPMENTS. WELL, YOU HAVE GOOD ENGINEERING JOB OR TEACHING JOB WAITING FOR YOU IN THAILAND IF YOU HAVE THE RIGHT CREDENTIALS.

I wish you could give me the names of your friends and their phone nos. I am not looking for a job as I am a consultant to a Thai company .But I can ask my company to do work with the bus companies and work with the institutes like ATI on some projects

[Rooster]

If you are consulting with a Thai company in Thailand, than you should be able to contact people at the ministry of education or science departments at these universities including contacting bus manufactures.

If more people lived more simply, less energy would be needed. The Western influence of cultured debauchery, and its all to common quest for power and prestige, undermines the quality of life, causing more people to need more for no reason other than to win at class warfare.
