Description

472130 months (1) The present invention is to provide a cold control method and rate operation I. According to the early operation of the refrigeration group and the lack of parents, a refrigeration air-conditioning switch group 1 of the air-conditioning system was set up. Unit F 1 After reading the area adjusted by R 1 〇 ~ 2 0 11 in the second picture, 々, turn out Shi Yingyu Women's Progress 1

It is about a kind of refrigeration energy-saving air-conditioning system which can calculate the required energy according to the value of "two f", the original unit makes the corresponding energy supply ^ θ to maintain the system at an optimized energy saving and high efficiency

F Empty refrigerating and air-conditioning room (area, complete energy over-improvement, city load side heat 2 is provided with 1-1, 1 sensor), providing refrigeration data sensing single set value T drive output power to fan motor M, but The energy demand of the system cannot change
