A refrigeration system having a refrigerant circuit including a condenser, a flow control device, an evaporator, and a compressor connected in series. The compressor is configured to circulate a cooling fluid through the refrigerant circuit. The refrigerant circuit has an inlet line fluidly connecting the condenser to the evaporator and a suction line fluidly connecting the evaporator to the compressor. A heater is positioned to heat the cooling fluid during a defrost mode, and a pressure control is coupled to the refrigerant circuit downstream of the evaporator. In the defrost mode, the pressure control apparatus is configured to increase system pressure during the defrost mode to maintain flow of refrigerant into the evaporator and to control flow of cooling fluid to the compressor.

A showcase includes: a casing having a front opening through which a product is picked up; a product storage located in the casing and including a shelf on which the product is displayed; a first airflow generator that sends air for a first air curtain to flow outside along the product storage; a second airflow generator that sends air for a second air curtain to flow outside along the first air curtain; and a controller that causes the first airflow generator to operate and causes the second airflow generator to reduce an output of the second airflow generator from an output at a first timing, upon arrival of a second timing when a break of the second air curtain due to disturbance is greater than a break of the second air curtain at the first timing.

A refrigerated display unit having an open-fronted cabinet providing a product display space accessible through an access opening provided by the open front. Cooling means produces cold air to refrigerate items in the product display space. A cold air curtain is provided across the access opening using a forwardly-positioned discharge outlet communicating with a supply duct and a forwardly-positioned return inlet in communication with a return duct receiving air from the air curtain. The air curtain is substantially unsupported by the any supplementary cooling airflow supplied into the product display space separately from the air curtain.

A showcase includes a casing having a front opening through which a product is picked up, a product storage located in the casing, a cold air outlet in a front upper portion of the product storage, and a cold air inlet in a front lower portion of the product storage. Cold air is forced to flow out of the cold air outlet in a downward direction and sucked into the cold air inlet. The showcase further includes an inlet port in the front lower portion of the casing at a position below the cold air inlet, a duct, a discharge port in a side wall of the casing, and an airflow generator that forces air in the duct to flow from the inlet port toward the discharge port. The air is sucked through the inlet port and the air in the duct is discharged through the discharge port.

A display includes at least one revolving door panel hinged to a box frame by means of a hinging means actuated by an actuation means The display has a movement component that can be coupled with the door panel to move the door panel, as well as a fast coupling/uncoupling means for the fast coupling of the movement component with the door panel to actuate the door panel by means of the actuation means, and permit the fast uncoupling of the movement component from the door panel to move the door panel manually, independently from the actuation means.

In an automated warehouse, if a controller receives an instruction to retreat a first carrier and if the first carrier is holding an article or if an article is housed in a housing shelf corresponding to an isolation region that is a retreat destination, the controller causes the first carrier to carry the article to a housing shelf to and from which a second carrier is able to transfer an article, then causes the first carrier to retreat, and then drives the second carrier within a range of a track except for the isolation region. When it is detected that one of first doors corresponding to the isolation region has been opened, the controller continues driving the second carrier.

A temperature monitoring and control system is provided. The system includes a plurality of temperature sensors for obtaining temperature readings of food items. The system is scalable and configurable with each sensor being capable of functioning as an individual sensor and/or as part of a grouping of sensors. The system is configured to obtain a variety of information, such as ambient air temperature, dwell time of food items, moisture levels, and the like, thereby enabling the system to recognize current and future temperature concerns. The system provides audio and visual warnings and visual displays. In some embodiments, the system performs one or more physical operation based on one or more detected condition. The system is further configured to distinguish between accurate temperature readings and inaccurate temperature readings and/or to otherwise determine if an obstacle is preventing a temperature sensor from obtaining an accurate temperature reading.

A diagnostics system for a display case includes a display case, a display device, and a remote controller, according to some embodiments. The display case includes a local controller, a refrigeration apparatus, and multiple sensors. The remote controller includes a processing circuit configured to receive diagnostics data from the local controller of the display case, according to some embodiments. The processing circuit is configured to identify one or more events using the diagnostics data and assign a rank to each of the one or more events. The processing circuit is configured to promote the rank of each of the one or more events based on an amount of time that each of the one or more events persists. The processing circuit is configured to operate the display device to notify a user regarding the one or more events and the rank of each event.

A cooling system includes an evaporator coil and a compressor fluidly coupled to the evaporator coil. A circulation fan is arranged to direct air through the evaporator coil and through a discharge air duct into a conditioned space. At least one sensor is disposed in at least one of the discharge air duct, the conditioned space, and the evaporator coil. An HVAC controller is electrically coupled to the at least one sensor and electrically coupled to the compressor. The HVAC controller is configured to receive a measurement of an HVAC parameter from the at least one sensor, determine if the HVAC parameter indicates frost formation on the evaporator coil, and, responsive to a determination that the HVAC parameter indicates frost formation on the evaporator coil, raise a saturated suction temperature of the evaporator coil.

A method includes providing, on a computing device, when a user of the device is authorized, a user interface including respective representations of first medication administration functions and second medication administration functions associated with storage of the one or more medications and, in response to determining that the computing device is within the first predetermined area, enabling the computing device to perform the one or more first medication administration functions associated with the first predetermined area to cause, responsive to a selection of a displayed representation of the one or more first medication administration functions, a respective electronic medication storage cabinet associated with the selected displayed representation to perform an operation regarding a physical storage of a medication associated with a patient of the one or more patients, and preventing the computing device from performing the one or more second medication administration functions not associated with the first predetermined area.
