Can a commercial establishment file a consumer complaint under the Consumer Protection Act, 1986 against another company for faulty goods or services provided?

Does it matter if these particular faulty goods were being used in their commercial premises or not?

As per the act, a person using the goods for commercial purposes is not a consumer.

However, suppose a company maintains a corporate guesthouse and installs a central AC system in this guesthouse. Can such a company sue the manufacturers if this AC system becomes faulty? Will they be considered as consumers under this act?

Please state any similar case laws if possible. 

Thanks in advance!!
