Air conditioning a person with a vest would be approximately 79 cents a day plus the cost of the vest. In most applications the vest is operated in lower temperatures and usually for less than eight hours of the day. Even in applications where a small compressor is leased to provide additional air capacity and only during the summer months the costs are very reasonable. This is about the cost of three Cokes a day, without the labor charge for drinking them. Purchased systems are even less expensive.
Air conditioning increases productivity.
Should there be any doubt, try cutting the air conditioning off for office personnel. Air conditioning in industrial applications is both reasonable and very cost effective. The expected increase in efficiency can provide a competitive advantage to most companies.
