REFRIGERATION APPARATUS
First Claim
1. A refrigeration apparatus (10) comprising:
- a heat source unit (100) including a compressor (110) configured to compress a refrigerant, a first heat exchanger (140) configured to cause heat exchange between the refrigerant and liquid fluid, a second heat exchanger (160) configured to cause heat exchange between the refrigerant and air, a casing (106) accommodating the compressor, the first heat exchanger, and the second heat exchanger, and a valve (162) configured to switch to supply or not to supply the second heat exchanger with the refrigerant;
a utilization unit (300) including a utilization heat exchanger (310), the utilization unit and the heat source unit constituting a refrigerant circuit (50); and
a controller (406) configured to control to operate the compressor and open or close the valve,wherein the controller is configured to open the valve to supply the second heat exchanger with the refrigerant to cause the second heat exchanger to function as a heat absorber when assessing that the refrigerant sent to the utilization unit needs to be decreased in quantity during cooling operation in which the first heat exchanger functions as a radiator.

Abstract
It is provided a refrigeration apparatus that uses liquid fluid as a heat source and is highly reliably configured to reduce the occurrence of dew condensation and freezing at a utilization unit during cooling operation in which a liquid fluid heat exchanger in a heat source unit functions as a radiator. An air conditioner (10) includes a heat source unit (100) having a compressor (110), a first heat exchanger (140) configured to cause heat exchange between a refrigerant and liquid fluid, a second heat exchanger (160) configured to cause heat exchange between the refrigerant and air, and a valve (162) configured to switch to supply or not to supply the second heat exchanger with the refrigerant, a utilization unit (300) constituting a refrigerant circuit (50) along with the heat source unit, and a controller (406) configured to control to operate the compressor and to open or close the valve (162). The controller opens the valve (162) to supply the second heat exchanger with the refrigerant to cause the second heat exchanger to function as a heat absorber when assessing that the refrigerant sent to the utilization unit needs to be decreased in quantity during cooling operation in which the first heat exchanger functions as a radiator.
