The input power is greater than the cooling capacity. Is this air conditioner correct? !

Input power 2337W. Refrigeration capacity 7200W. Is this air conditioner correct? See picture.
It’s the energy efficiency ratio, 7200 divided by 2337, no problem
Input power is greater than output power?
Cavities and chillers are such energy efficiency principles. Although the output energy is greater than the consumed electrical energy, it looks more powerful than a perpetual motion machine and does not comply with the conservation of energy. In fact, in addition to the incoming and outgoing electric energy, the work is designed to exchange heat with the environment and absorb energy from the environment, so the energy generated is higher than the input electric energy.
Assuming the air conditioning energy conservation formula A+B=C+D, people only care about the input electric energy A and cooling capacity C. B and D are the ability obtained from the environment and the ineffective energy transferred to the environment respectively. Just because B and D don't care doesn't mean they don't exist. If B>D, and it is much larger, the input energy will be much lower than the output energy. How to make B>D much larger is a matter for the manufacturer.
For the energy of the air conditioning refrigeration system, cooling capacity + compressor power = heat release of the refrigerator.
Haha, brother, I wanted to post this question to ask everyone a few days ago. This involves thermodynamics. 1. Your electrical energy (input power) is converted into mechanical energy (fan and compressor). This is consistent with the law of conservation of energy. 2. Your cooling capacity and heat exchange are incomparable with your electrical energy. The cooling capacity is the heat absorbed by the evaporation of the refrigerant. The heat absorbed by the refrigerant is equal to the heat released by the air. This is also consistent with the conservation of energy. 3. The entire refrigeration cycle is the cooling capacity plus the compression work equal to the heat of condensation. This is a reverse Carnot cycle that conforms to the conservation of energy.~~
In layman's terms, an air conditioner is a heat pump that sends indoor heat to the outdoors, making the indoors cooler and the outdoors hotter! To complete such heat transportation, we need equipment such as compressors, so the energy we input is mainly used for compressor work. That is to say, the freight we spend can never be more than the cost of the goods the driver pulls for us, otherwise there will be no profit, so the higher the energy efficiency ratio, the better.
There is of course a big difference between air conditioners and heat pumps. There is Freon in the air conditioner for cooling.
