Regarding fluorine pump type energy-saving air-conditioning products, which of the following statements is correct ((multiple choice)

A.

No or less compressors are turned on in autumn, winter and spring, indirect natural cooling and energy-saving operation, but it does not necessarily reduce OPEX. Because maintenance work and maintenance difficulty are simultaneously increasing

B.

The reliability of fluorine pump is relatively hidden, and it is easy to be damaged due to cavitation (gaseous refrigerant exists near the blades)
