Executive summary report The Study of Review of Air Conditioner and Refrigerator Energy Efficiency Standard to

propose as Ministry Regulations in accordance with The Energy Conservation Promotion Act

(B.E. 2550) 1. Introduction

Today, air conditioner is one of major home appliance which is widely used in Thailand to maximize comfort in cooling room. Air conditioner has sold approximately 1.5 million units per year and is likely to use soared.

While refrigerator is also one appliance that use a lot of energy due to the need to be plugged in at all times to keep cool in the refrigerator. Today refrigerator is appliances necessary for all the family. The demand of refrigerator tends to raise each year around which is approximated in average value at 1.6 million units in the last 6 years. Household refrigerators in the market are available in various sizes ranging from 40 -260 liter for one – door refrigerator and from 140-725 liter for two-door category. It has electricity consumption starting from 50-200 watts with energy consumed throughout the lifespan.

Department of Alternative Energy Development and Efficiency (DEDE) under The ministry of energy has been conducted a Ministerial Regulation on high efficiency air conditioner and regulations requiring highly efficient refrigerators on the year B.E. 2552 and has reviewed the Ministry's completion. But since B.E. 2557, when the Thai Industrial Standards Institute (TISI) has a plan of action standardized tests of the air conditioner according to ISO 16358-1 which based on technology revision. The current with both air conditioner fixed speed type and air conditioner variable speed type (Inverter) by the anchor. There are plans to improve testing standards of TIS. 1155-2553. according to ISO 16358 and amended standards, energy efficiency, air conditioning TIS. 2134 in the year B.E. 2559. TISI also plans to improve testing standards of household refrigerator TIS. 455, in accordance with IEC 62552 Edition 2 and standards efficient refrigerator TIS. 2186 in the year B.E. 2559 as well.

This is why DEDE should conduct a study to review the energy efficiency of air conditioners and refrigerators. Compliance testing with the new TIS standards of both products which plans to be adopted in 2559 by the preparation Draft Ministerial Regulation of air conditioners and refrigerators under Energy conservation promotion Act. As well as to give the draft of Minimum Energy Performance Standard (MEPS) of both products given to TISI for

revision MEPS scale. This process will promote the use of energy-efficient products and eliminate unefficient products from the market.

2. Air conditioners

2.1 Market information of air conditioners in Thailand

Considering the status of manufacturing industry of Thailand, we found that the production of air conditioning has an important role. The manufacturing industry of Thailand increased significantly. Considering the proportion of appliances production for Industry increase from 3.7 percent in year 2000 to 5.8 percent in the year 2009. Export air conditioning increased steadily as well from 1.08 billion in the year 2000 to be 3.88 billion US dollars in the year 2011 which manufacture of air conditioners mainly producing for export at around 90 per cent of total production. Air Conditioning All Meanwhile, the air conditioning industry is also a key factor to the recovery of Thai GDP, the industrial sector after the flood. Because the industry has recovered relatively quickly and reflection from the manufacturer Air Conditioning contracted 53.7 percent year-on-year in the fourth quarter of 2554 grew at an annual 12.5 percent in the second quarter of 2555 is a major cause. Demand deposits both from home and abroad since the late 2554 caused an acceleration in industrial production with demand during the reconstruction after the flood, however, considering the third quarter, it was found that the production of air conditioning back to slow down slightly to 0.2 percent because the industry is affected, as well as other industries emphasis on production for export due to slowdown in the global economy especially from US market And the European Union (EU).

During the years2012 - 2015 Thailand has increased value of imported air conditioners

constantly. Seems to be the result of a free trade agreement with the ASEAN import tariffs to zero percent. The source said Malaysian air conditioner is a major imports accounted for by imports to increase. As a result of the investment of the multinational Japanese company Panasonic chose Malaysia as a production base for air-conditioning and exports to the region. On the other hand, like the air conditioning, Thailand imported from Japan decreased

Production of air conditioners Thailand Production for export The exports to Asia the most. The top five export markets of Thailand, Vietnam, Australia, Singapore, United Arab Emirates and India.

2.3 Air conditioner sales value in Thailand

Considering the air conditioner market in Thailand we found that the air conditioning market has been driven primarily by climate, hot summer. The overall competition of air conditioner makers are competing in terms of quality, functionality, design, technology and innovation especially energy-saving technology, air purification systems, cooling quickly and evenly or even trending by using mobile devices like smart phones and tablets to operate the remote control and so on.

However, in 2557 it was found that the sales of air conditioners is growing at a slower pace than the year 2556 clearly resulted in the year 2557 with total sales. Air conditioning is

However, in the year 2557 - 2558 refrigerator market grew only 1-2% of the average

price of Baht 6,000 per unit for the low growth of the domestic economy continues to slow.

Consumers put off buying a new refrigerator to use or replace existing. The market share by

brand are shown in figure 5.

3.2 Export and Import data of refrigerators

The export value of the household refrigerators and parts of Thailand in the year 2015

found that the overall value of exports of household refrigerators from Thailand to partner countries is shrinking. The value of exports to top three trading partners are Japan, Vietnam and Australia, respectively, can be seen that the value of exports for household refrigerators and components to Japan in 2558 has shrunk to 15.13%, but in Vietnam increased of 28.48%, and Australia increased 22.73% respectively compared with year 2014.

Fig 6: Export and Import value of refrigerator of Thailand year 2012-2015

Source: customs department, analysis by EEI

The import value of household refrigerators and components in year 2015 equal to US $ 127.29 million which more value than import value of year 2014 (US $ 126.39 million). However the exports value of year 2015 was valued at US $ 1615 million less than export value of year 2014 with exports 1,700 million. Among year 2556-2558 with the value of imports increased probably due to result of trade agreements between the countries and the reduction in import duty is likely to be reduced to 0%.
