What is the prospect of consulting HVAC professionals to develop air conditioners in air conditioning companies?

For the R&D work of air-conditioning companies, there is not much difference between learning HVAC, refrigeration and air conditioning, and the same is true for professional basic courses. There is no problem for these people with different majors to engage in R&D work of air-conditioning products.

It is best to find a large air-conditioning company just after graduation and try to avoid going to some small air-conditioning companies.
