Abstract
An automobile air conditioner unit is provided with a compressor equipped with a number of compression chambers. At the start of air conditioner operation, less than all of these compression chambers are operated to avoid liquid compression. After start up, the number of compression chambers in operation will depend upon the air conditioning load, with a fewer number of chambers being operable at times when the load is low, as during temperature maintainance, as opposed to initial cool-down.
