#Air conditioning#The weather is getting warmer and spring is getting stronger, which is a good time to buy air conditioners. No, I also bought these two new air conditioners for my home, and I will share them with you here.
A few days ago, I wrote an article "How to quickly buy air conditioners", friends who want to buy air conditioners can read this article first to understand the purchase ideas.
The 38-section promotion has just passed, and with the help of JD's 10 billion subsidy activity, the sales of air conditioning plants are gratifying.
Gree Yunjia topped the list for 18 consecutive days and sold 20,000 units in half a month.
Midea Fengzun also claims to sell 7800+ units per month, which is also quite powerful.
The price of these two air conditioners are fluctuating around 3,000 yuan, which can be said to be the representative products of the two factories at this price, first of all, let's take a look at the official parameters of Yunjia and Fengzun, as shown below:
After reading the official announcement parameters of the two, let's summarize as follows:
1. Both are 1.5 hp "new level" energy efficiency, in line with the recommendation of "Quick Method to Buy Air Conditioners", both of which meet the requirements.
2. The applicable area of Midea Fengzun is 15-23㎡, and the applicable area of Gree Yunjia is 16-20㎡, and the applicable area is similar, and the general bedroom is enough.
After all, the parameters are too superficial, to know the real situation or to disassemble the machine to see, and then look at a wave of disassembly pictures:
The following is a picture of Gree's disassembly:

The appearance of the cross-flow fan 63cm·
The brushless DC fan of the internal unit is Kaibang's
Here is a partial disassembly diagram of Midea:
The panel of Midea is very smooth with a mirror surface and easy to wipe clean
The PC version has an additional humidity sensor, and the dehumidification mode is more targeted
Midea internal machine computer version
Midea's computer board is independent, the CPU is glued, and with a wifi module, which can be remotely controlled and linked to the smart home system, Gree does not have a WiFi module and no response function.
2 strainers for easier removal
The wind deflector is a large arc, which can realize the wind of heaven and earth
Stepper motor with upper and lower wind deflectors
Stepper motor for left and right wind deflectors
The copper tube size is 4 cm longer than Gree
The fan is also 4cm long
The design inside the evaporator is similar
Welling motors

The external fan motor is still a Welling motor
The condenser is a single row of copper tubes

Compressor model
The sticker of the compressor is too close inside, and it is a little difficult to take pictures with the mobile phone, but it is lined up to the model, and you can check it on the Internet.
Heatsink length
The heatsink is deep
The heatsink is wide
Midea's heat sink is not as large as Gree's, but the gap is not particularly large.

After looking at so many pictures, the fireworks are chaotic, or to sum up:

In the case of similar compressor displacement and also equipped with electronic expansion valve, Gree's external heat exchanger heat exchange area is much larger than Midea's, but the windward area of Midea's internal heat exchanger is much larger than Gree's, and Gree does not support high and low temperature start, let alone APP, then it is more troublesome when we configure smart home. But the sheet metal of the beauty is really much thinner than Gree, and the shell of the external machine has been disassembled and deformed by me, not because I am violent, but because it is really a little thin.
Conclusion:
If you choose between these two models, it is recommended to buy Gree, although Gree nominally does not support low temperature and high temperature start, but in general, it is started with a high temperature of minus 15 ° and 55 ° C, there is no wifi function, in fact, you can also use Huawei's air conditioner companion socket to achieve remote control, most of the air conditioners that support remote control are basically OK.
