Title:
HEAT SOURCE UNIT
Document Type and Number:
Japanese Patent JP2015187538
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat source unit which is improved in reliability by dispensing with an oil equalization mechanism between compressors to prevent deterioration in performance due to oil equalization and reducing the risk of whole stop of the unit in the event of failure of the compressors, as well as having plural circuits of refrigeration cycles.SOLUTION: A heat source unit includes: a first hydrothermal exchanger and a second hydrothermal exchanger to which water flow channels are connected in series; and plural circuits of independent refrigeration cycles which are connected to each of the hydrothermal exchangers and through which refrigerant for exchanging heat with water in the water flow channels is flown. The plural circuits of refrigeration cycles respectively include an air heat exchanger, an expansion valve, a four-way valve and a compressor. Two circuits of the refrigeration cycles are connected to the first hydrothermal exchanger and the second hydrothermal exchanger in parallel.
