Problems solved by technology

In particular, in the heat exchange unit for supplying hot and cold water, since the temperature of the stored refrigerant/water heat exchanger changes independently of the temperature of the outside air by operating the heat source unit, it is easy to be stored in the heat exchange unit Condensation occurs on the control device on the heat exchange side in the exchange unit, and the control device must be adequately insulated, which constitutes a major cause of cost increase

Abstract

A refrigeration device having a structure in which the other sides of a plurality of plate refrigerant/water heat exchangers 20a, 20b are connected in parallel to cold and hot water pipes (4a), ( On the cold and hot water circuit constituted by 4b), connect one side of the plurality of plate refrigerant/water heat exchangers (20a), (20b) in series to the refrigerant piping (3a) connected to the heat source unit (1) ), (3b) on the refrigerant circuit. In addition, a heat exchanger (20c) for exchanging heat between the refrigerant circulating on the upstream side of the refrigerant/water heat exchangers (20a), (20b) and the refrigerant circulating on the downstream side is provided, and a heat exchanger (20c) is provided to detect A first refrigerant temperature sensor for detecting the temperature of the refrigerant flowing on the side and a second refrigerant temperature sensor for detecting the temperature of the refrigerant flowing on the downstream side, and any one of the temperatures detected by the first and second refrigerant temperature sensors is selected. temperature to operate the freezer.

Description

technical field [0001] The present invention relates to a refrigeration device configured by connecting a heat source unit and a heat exchange unit. Background technique [0002] It is well known that a currently used refrigerating device is constructed by connecting a heat source unit that is equipped with a compressor that compresses and discharges a refrigerant, and a heat exchange unit that is equipped with a compressor for cooling the refrigerant and water supplied from the heat source unit. The refrigerant / water heat exchanger for heat exchange generates hot and cold water to supply to the use-side heat exchanger (for example, refer to JP-A-08-233405 and JP-A-08-233398). [0003] In such a conventional refrigerating device, particularly the refrigerating device disclosed in the former Japanese Patent Application Laid-Open No. 08-233405, a plurality of refrigerant / water heat exchangers formed to be spirally mounted on the heat exchanging unit are provided. A two-layer ...
