Title:
HEAT SOURCE UNIT FOR REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2018025381
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To expand an operable temperature range of heat source water in a heat source unit for a refrigeration device having a heat source side heat exchanger for exchanging heat between a refrigerant and the heat source water.SOLUTION: A heat source side heat exchanger (40) for exchanging heat between a refrigerant and heat source water is provided in a heat source unit (11) for an air conditioner (10) which serves as a refrigeration device. The heat source side heat exchanger (40) includes a plurality of heat exchange sections (41a, 41b) and can control the size of a heat exchange region by changing the number of the heat exchange sections (41a, 41b) to which the refrigerant is caused to flow in. A controller (70) of the heat source unit (11) adjusts the size of the heat exchange region of the heat source side heat exchanger (40) on the basis of a differential pressure index value.SELECTED DRAWING: Figure 1
