Abstract:
1. A scroll air compressor including an orbiting scroll member having a substantially spiral wrap, a fixed scroll member having a substantially spiral wrap corresponding to the wrap of the orbiting scroll member, and a motor that generates driving force to cause the orbiting scroll member to rotate with respect to the fixed scroll member, wherein compression channels into which water is injected are each formed between intake port and exhaust port, the scroll air compressor comprising: temperature sensors for detecting temperatures in the compression channels; regulating valves for controlling the amounts of water to be injected into the respective compression channels; and a controller configured to calculate a difference between the temperatures in the compression channels detected by the temperature sensors, calculate correction amounts of opening degrees of the regulating valves such that the difference between the temperatures in the compression channels detected by the temperature sensors is small, generate control signals based on the calculation, and output the control signals to the regulating valves to control the regulating valves.
