Title: INTEGRATED TYPE AIR CONDITIONING SYSTEM, CONTROL DEVICE THEREFOR
Abstract:
Mode (A) is independent operation of an indirect external air cooler, modes (B) and (C) are joint operation of an indirect external air cooler and a general air conditioner, and mode (D) is independent operation of a general air conditioner. With mode (B), there is a restriction such that the rotational speed of the compressor is always at a minimum, but with mode (C) there is no such restriction. The switchover decision for these modes is calculated on the basis of the measurement results of the warm air temperature, the cold air temperature, and the external air temperature, etc., and is performed on the basis of the maximum cooling capacity (Qi), and the required cooling capacity (Qreq), etc., of the indirect external air cooler.
