Document Type and Number:
Japanese Patent JP6819186
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a freezer for rapidly suppressing a drift phenomenon.SOLUTION: A freezer 100 comprises: utilization units 30; a plurality of heat source units 10 including a compressor and arranged in side-by-side in respect to the utilization unit 30; a liquid side communicating pipe LL for connecting each of the utilization units 30 with each of the heat source units 10; and a controller. The heat source units 10 comprise: a liquid side refrigerant pipe communicating at its one end with the liquid side communicating pipe LL; a first adjustment valve arranged at the other end of the liquid side refrigerant pipe. The controller executes a drift suppression control when it is assumed that a high pressure liquid side pressure of the heat source units 10 is different from the high pressure liquid side pressure of another heat source unit 10 in such a degree as one in which a drift phenomenon occurs and controls an opening degree of the first adjustment valve of the low pressure heat source units 10 where the high pressure liquid side pressure is low to a drift suppression opening degree (an opening degree in which the high pressure liquid side pressure is increased to such a degree as one in which a drift phenomenon is suppressed).SELECTED DRAWING: Figure 1
