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
[0008] On the other hand, in the refrigerating device disclosed in JP-A-08-233398, since only the traveling side temperature and the returning side temperature of the cold and hot water supplied from the heat exchange unit to the use side heat exchanger are detected, it is usually Can only operate with emphasis on efficiency
In addition, since the refrigerant supplied from the heat source unit to the heat exchange unit cannot be sufficiently subcooled, the heat exchange of the refrigerant cannot be efficiently performed.

A refrigeration device is constructed by connecting a heat source unit and a heat exchange unit. The heat source unit is equipped with a compressor that compresses and discharges the refrigerant, and the heat exchange unit is equipped with a heat exchanger that performs heat exchange between the refrigerant and hot water supplied to the use-side heat exchanger. A refrigerant / water heat exchanger and a refrigerant heat exchanger are disposed within the heat exchange unit. The refrigerant / water heat exchanger exchanges heat between the refrigerant supplied from the heat source unit and the cold and hot water supplied to the utilization side heat exchanger, and the refrigerant heat exchanger performs heat exchange between the refrigerant / water The refrigerant circulating on the upstream side of the water heat exchanger exchanges heat with the refrigerant circulating on the downstream side, and a first refrigerant temperature sensor for detecting the temperature of the refrigerant circulating on the upstream side and a first refrigerant temperature sensor for detecting the temperature of the refrigerant circulating on the downstream side are provided. The second refrigerant temperature sensor for refrigerant temperature selects any one of the temperatures detected by the first and second refrigerant temperature sensors to operate the refrigeration device.
Description
[0001] This application is a divisional application of the Chinese patent application with the application number 200410102097.3 entitled "Refrigerating Device with Refrigerant / Water Heat Exchanger" submitted to the Chinese Patent Office on December 23, 2004. technical field [0002] The present invention relates to a refrigeration device configured by connecting a heat source unit and a heat exchange unit. Background technique [0003] 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). [0004] In such a conventional refrigera...
