Energy efficiency indicators of kitchen air conditioners mainly include coefficient of performance (COP) and energy efficiency ratio (EER), which are used to measure the efficiency of air conditioners.
Coefficient of performance (COP)
The coefficient of performance (COP) is an important indicator for measuring the refrigeration efficiency of air conditioners. The COP requirements of different types of air conditioners under different cooling capacities are as follows:
Piston and scroll air conditioners: When the rated cooling capacity is less than 528KW, the COP should not be less than 2.40; 528~1163KW should not be less than 2.60; greater than 1163KW should not be less than 2.80.
Screw air conditioners: When the rated cooling capacity is less than 528KW, the COP should not be less than 3.10; 528~1163KW should not be less than 3.30; greater than 1163KW should not be less than 3.60.
Centrifugal air conditioner: When the rated cooling capacity is less than 528KW, the COP should not be less than 3.40; when the rated cooling capacity is 528-1163KW, it should not be less than 3.70; when the rated cooling capacity is greater than 1163KW, it should not be less than 4.0.
Energy Efficiency Ratio (EER)
Energy Efficiency Ratio (EER) is a measure of the energy efficiency level of air conditioners under specific environmental conditions. For air-cooled or evaporatively cooled piston and scroll air conditioners, the EER requirements are as follows:
When the rated cooling capacity is less than or equal to 50KW, the EER should not be less than 2.40; when it is greater than 50KW, it should not be less than 2.60.
For air-cooled or evaporatively cooled screw air conditioners, when the rated cooling capacity is less than or equal to 50KW, the EER should not be less than 2.60; when it is greater than 50KW, it should not be less than 2.80.
