  • Publication number: 20200386461
    Abstract: A double pipe icemaker includes an inner pipe, and an outer pipe provided radially outside the inner pipe and coaxially with the inner pipe. The outer pipe allows a cooling target to flow in the inner pipe and a refrigerant to flow in a space between the inner and outer pipes. The outer pipe has a wall provided with at least one nozzle to jet the refrigerant into the space. The nozzle has a jet port. The jet port may allow the refrigerant to jet in a radial direction including at least an axial direction and a circumferential direction of the inner pipe. A shielding plate may be provided ahead of the jet port in a jetting direction such that the refrigerant hitting the shielding plate expands along a surface of the shielding plate in a radial direction.

  • Publication number: 20190242632
    Abstract: Provided is a refrigeration apparatus that secures safety while suppressing an increase in cost. A refrigeration apparatus performs a refrigeration cycle in a refrigerant circuit including a compressor, a heat source-side heat exchanger, and a usage-side heat exchanger. The refrigeration apparatus comprises a usage-side fan providing an air flow, and a controller. The usage-side fan is disposed in a target space where inside air is cooled. The controller performs a refrigerant leak determination process to determine whether a refrigerant leak occurs, based on a state of a refrigerant in the refrigerant circuit. When the controller performs the refrigerant leak determination process to determine that a refrigerant leak occurs, then the controller performs leakage refrigerant agitation control to operate the usage-side fan so as to suppress local emergence of a region where the refrigerant leaks at a high concentration in the target space.
