The fight for air conditioning!

You know, in my department all non-smokers and workers. Therefore, we usually do not go to smoke, and very rarely spend time on empty conversations. In a word - conscientious employees. But with the onset of summer heat, and with it the stuffiness, it became simply impossible to work normally in rooms without air conditioning and ventilation. I think many will agree with me. From my own health and well-being of my colleagues, I notice that after 2 hours, thoughts begin to get confused, and stuffiness takes away attention. Have to go out once an hour for 10 minutes to breathe air. But putting my hand on my heart, I’ll say that it doesn’t help :( Yes, and it does not allow
me to concentrate on returning to difficult tasks. I have tried more than once to defend the purchase of an air conditioner from investors, but all to no avail. Maybe because I acted emotionally.
But tomorrow, and every subsequent day, I decided to continue to defend the acquisition of a normal air conditioner.
And I will do it like this:
New day = A new argument,
and until they buy it!
Help me gather arguments for every day. I want to try the remaining 20 days of this month to aggressively and reasonably achieve victory and achieve it in the end!
For example, for tomorrow I prepared this argument:
if all employees of the department (there are 6 of them) go out 6 times for 10 minutes, then the company will lose 180 hours a month. Given that the average income of a programmer in our company is 40,000, we get a loss in this amount.
I beg you to help me in this quest and write your comments with possible arguments that I can apply. I promise not to compromise and not to capture enemies :)
