Document Type and Number:
Japanese Patent JP2017078525
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air conditioning system in which a general-purpose multi-type air cooling heat pump package is converted into one for a clean room.SOLUTION: An air conditioning system 1 comprises: an outside air processing air conditioner having a first heating/cooling simultaneous type outdoor unit 51 and a second heating/cooling simultaneous type outdoor unit 52, and a plurality of first system coils 61 and a plurality of second system coils 62; a plurality of coil control parts 40; and a main control part 30. The first heating/cooling simultaneous type outdoor unit 51 and the second heating/cooling simultaneous type outdoor unit 52 output a protection control request signal to the main control part 30 before performing protection control of the own machines. When the main control part 30 has received the protection control request signal, it selects a coil capable of cancelling temperature change by the protection control out of the plurality of coils, outputs a protection control execution permission signal to the first heating/cooling simultaneous type outdoor unit 51 and the second heating/cooling simultaneous type outdoor unit 52, and outputs a control signal so as to cancel the temperature change by the protection control with respect to the coil control part of the selected coil.SELECTED DRAWING: Figure 1
