Working from home under the epidemic, facing the scorching summer, of course I want an air conditioner that cools quickly and saves electricity.
The Consumer Council tested 14 models of inverter split air conditioners commonly known as "1 hp", including testing the heating performance of 7 models of heating and cooling air conditioners.
The results found that the heating and cooling air conditioners of Midea, Mitsubishi Electric, Mitsubishi Heavy Industries, Daikin, and Samsung all received the highest score of 4.5 points, but the price difference was 2.5 times. Among them, the flattest Samsung was only 4,680 yuan, and the most expensive Mitsubishi Electric sold The price is 16,400 yuan.
Although the cooling seasonal performance factor (CSPF) or the heating seasonal performance factor (HSPF) calculated energy efficiency level of 1 for all samples, they differed considerably in energy efficiency and energy saving.

Midea, Mitsubishi Electric get the highest score, the price difference is big
The Consumer Council tested 14 variable frequency split air conditioners commonly known as "1 HP", including Midea (MS-09HRF8B), Mitsubishi Electric (MSZ-LN09VFR/ MUZ-LN09VF), Mitsubishi Heavy Industries (SRK25ZSXH-S/ SRC25ZSXH-S), Daikin's (FTHM25RAV1N/ RHM25RAV1N) and Samsung's (AR09TXHAAWKN) heating and cooling air conditioners all got the highest score of 4.5 points.
The cheapest is Samsung, which sells for 4,680 yuan, while the most expensive is Mitsubishi Electric, which sells for 16,400 yuan, a difference of 11,720 yuan. There are also good choices for products with different price levels.
All products are above the claimed cooling capacity
In terms of cooling capacity, the measured cooling capacity of the 14 models ranges from 2.55 to 2.88 kW, all of which are higher than their claimed cooling capacity.
As for the 7 models of heating and cooling air conditioners with heating function, their heating capacity performance differed by about 19% (2.67 to 3.30 kW), among which 4 models had higher heating capacity than their claimed values, including Midea (MS-09HRF8B) , Daikin (FTHM25RAV1N/ RHM25RAV1N), Samsung (AR09TXHAAWKN), York (YDEK09/ YDDK09).
The heating capacity of the remaining 3 samples is lower than their claimed value, namely Mitsubishi Electric, Mitsubishi Heavy Industries, and Panasonic.
The Consumer Council has put forward 10 major factors to help the public understand the electricity consumption of air conditioners.

Fully compliant with Class 1 energy label but with big difference in energy saving
When purchasing an air conditioner, the public is most concerned about the energy saving function.
In terms of energy efficiency, all samples met the current Level 1 rating standard of the Mandatory Energy Efficiency Labelling Scheme, but there are still more than 30% differences in energy efficiency among products.
In the category of heating and cooling air conditioners, the highest CSPF value is 7.72 in the United States, while the lowest value in York is only 5.40, a difference of 30%, while the difference between the net cooling air conditioners and the non-slim outdoor units is higher, reaching 11.3% .
As for the heating energy efficiency of heating and cooling air conditioners, it is reflected by the HSPF value. It is found that the highest HSPF value is Mitsubishi Heavy Industries, with 6.13, and the lowest is York, with 4.07, a difference of 33.6%
Mitsubishi Electric's most energy efficient refrigeration
The Consumer Council also estimated the annual electricity cost of each sample, calculated at $1.3 per kilowatt-hour of electricity. Assuming that the air-conditioning is turned on 180 days a year, 12 hours a day, it is estimated that the average annual electricity cost for each sample is Mitsubishi Electric, which uses 401 Yuan, and the most expensive is the Lexin card, which costs 581 yuan.
As for heating, the cheapest is Daikin and the most expensive is Panasonic.
Assuming that the heating is turned on 25 days a year, 12 hours a day, it is estimated that the annual heating electricity cost of 7 models of heating and cooling air conditioners ranges from $35 to $53.
Midea and Samsung are the most peaceful indoors
Among the various products, Midea and Samsung are the quietest indoors, scoring 4.5 points.
Midea, Mitsubishi Electric, Mitsubishi Heavy Industries, and Hitachi scored 3.5 for lower outdoor noise levels.
In terms of air supply volume, in the cooling mode, the air supply volume of Midea, Mitsubishi Heavy Industries, Fuji Electric, Jumbo and Hitachi is relatively high.
