There are no refrigetator operated based on reversed carnot cycle because

Explanation:
Carnot cycle is devised keeping in mind the idea of creating the best possible cycle. It has two isentropic and two isothermal processes.
Isentropic process demands absence of friction and perfect insulation. Also process must be extremely fast to make sure that no heat is lost.
Isothermal process demands heat transfer at a constant temperature difference. A close match of this would be a quasi static process, which must be extremely slow so that at every state equilibrium is maintained.
Two extremely fast, Two extremely slow, even if you created a machine working on carnot cycle (of course you can’t actually create it) just think about the enormous size of the fly wheel that would be needed to make this engine work. Fly wheel of mass equal to mass of earth might even turn out to be lighter than required. So…
Engine based on carnot cycle can’t be created
Even if created can’t be operated.
Enjoy.
