Refrigeration capacity refers to the total heat discharged from a closed space, room or area per unit time when an air conditioner is used for refrigeration. Large-capacity air conditioners are suitable for situations with large room area and fast cooling speed. For example, the cooling capacity of 2500W air conditioner is the rated cooling capacity of bedroom area 15 square meter.
What does the rated cooling capacity of air conditioner mean?
Rated refrigeration and air conditioning capacity refers to the refrigeration work of air conditioning with normal refrigeration capacity, and the unit is kcal. Refrigeration capacity: the total heat from a closed space, room or area per unit time when the refrigeration and air conditioning is running, in W. Refrigeration power: when the air conditioning is running, the total power consumption is its refrigeration capacity, and the refrigeration capacity of block 1 in the rated time is 2000 kcal, which needs to be multiplied by 1. 162 to be converted into international units. Therefore, block 1 is 2000 kcal, so the cooling capacity of 1 chip is 2000 kcal × 1. 162 = 2324 (w), where w (watt) refers to the cooling capacity, especially (w) refers to the cooling capacity. Extended information: If Tongma air-conditioning products have large capacity, the relative refrigeration capacity of the products will be more prominent, but for friends who buy air-conditioning, we also need it when buying. We need to comprehensively evaluate the effect, calorific value and noise value of the products, and then air-condition them to avoid unreasonable consumption. The energy efficiency of air conditioners usually refers to the refrigeration energy efficiency ratio (EER) of household air conditioners, which refers to the ratio of rated refrigeration capacity to rated power consumption. However, heating and cooling household air conditioners also include the concept of heating energy efficiency ratio (COP), which refers to the ratio of rated heat to rated power. But when we talk about air conditioning efficiency, we usually refer to the refrigeration efficiency ratio (EER), which is the national standard basis for determining the energy efficiency level. Generally speaking, air conditioning efficiency refers to how much air conditioning/heating can be generated by the same amount of electricity. Its mathematical expression is: EER= refrigerating capacity/refrigerating capacity power consumption COP= heating energy consumption/heating power consumption. The higher the EER and COP values, the lower the energy consumption of air conditioning and the higher the performance ratio.

How to calculate the cooling capacity of air conditioner
Ground source heat pump unit (or ground source water) is not what you understand. You said that pumping groundwater through a heat exchanger and then returning it [it must be pumped or it will collapse] This kind of unit is called water system and ground source buried heat pipe, for example, the unit that takes heat through a water condenser, and then the cooling efficiency of soil water and air through these pipes is more efficient and natural than that of ordinary air conditioners. The cooling capacity of 1 and 20 kW units is usually sufficient. Because Internet cafes are generally not full, but if it is very hot and the computer configuration is high and the power is high, you should have at least 400 watts/square meter and 50 kilowatts of heat dissipation capacity. But for ordinary internet cafes, even if they are full, it is not enough to cope with the situation that every machine is surrounded by a group of people. It depends on whether your organization supports this working mode. For example, some unit hosts [or compressors] have frequency modulation function, but at the same time, cooling towers [or condenser fans] should also have frequency modulation function. In addition, I advocate a small swimming pool, and a smaller one is acceptable. Of course, the bigger the better, do a good job of heat preservation, use similar water to store the cold buffer, avoid the adjustment of the main engine, and deal with some unexpected events, such as the sudden increase of personnel and the sudden increase of refrigeration capacity. 3, the owner does not open, the capacity is zero, we can think that the owner here is equivalent to our air conditioning compressor, but for the ground source heat pump, if your soil is cold, you can use the bypass heat exchanger to exchange soil energy, so only turning on the water pump without starting the unit will also produce a small amount of cold energy, but it is not obvious, but if the soil temperature is not very cold and the temperature difference is not very large, then don't turn on the main engine. If the groundwater you use is an underground water source unit (water source heat pump), in any case, if the temperature difference with room temperature or the temperature difference you want to achieve does not exceed 10 degrees, the direct and circulating effect is not obvious, and it will be a little cold and a little hot through the main engine to reach a sufficient temperature difference.
What is the cooling capacity and heating capacity of the air conditioner?
Do you know the inverse Carlo cycle? In Baidu's "Vapor Compression Refrigeration Enthalpy and Humidity Diagram", you will see that the heat must be greater than the refrigeration capacity, and the energy consumption of the compressor should be included in the heat instead of the refrigeration capacity. In other words, the heat of the air conditioner is greater than the cooling capacity, which is determined by the working principle.
