I am not an expert on compresor air conditioning but from my experiance of being in cars with them fitted most seem to work eficantly at engine ideling speed or just a bit over as most computer cars seem to bump the idle speed up a litte when the air con is switched on . i havent done any exact measurements on pully sizes but just from observation i am gueseing that they are slightly geared up from the engine crank shaft posibly around 1to 1.5 but that could easily be determined by a quick measurement of an existing set up and doing a quick calculation . So asuming that the motor idle speed is around 500 to 700 rpm then compresor speed would be around 750 to 1050 rpm what horse power they consume i am not sure of but some one more in the field would be able to tell you . As for just takeing a complete system out of a car and driveing it off your turbine i cant see why it wouldnt work if you have it geared down to suit the compresor speed and have enough horse power to run it . Im gueseing you will need between 1.5 to 3 hp depending on the type and size of compresor . I had some friends who lived on an Island off the Australian Queensland coast . They had a car air compresor set up on a 6 hp Southern Cross diesle engine which they ran for aproximatly 4 hours per day and it was conected to a huge freezer around 8 ft long by 3 ft deep x 4 wide . It also ran a 32 volt generator into bateries for night time lighting .They used to freeze their fish catch with it until they had enough to take to the main land for sale. They had to run it longer hours when it was first loaded with fish though . So i guesing that you would not have any problems geting below 0 celcius with a car type air conditioner compresor .Also if you use some of your exausted water flow from the turbine to cool the condensor it would be quite more efficant .My friends set up was air cooled and some days the air temp would be over 40 c in summer.
