A refrigerated transport system comprises a body enclosing a refrigerated compartment. A refrigeration system (29) comprises first and second vapor compression loops each having: a refrigerant charge; a compressor (36A,B) for driving the refrigerant of the refrigerant charge; a first heat exchanger (38A,B) positioned to reject heat to an external environment in a cooling mode; and a second heat exchanger (42A,B) positioned to absorb heat from the refrigerated compartment in the cooling mode.

A modular arrangement for use in vapor-compression refrigeration system includes an evaporator, oil separator, condenser and oil cooler, arranged inside an outer casing with a longitudinal cylindrical shell and the end plates in both ends of the shell. The shell includes three separate parts, separated from each other by arranging first and second partition walls between the parts. The first part includes the evaporator, the second part includes the oil separator and the third part includes the oil cooler and the condenser. The third part including a combination of the oil cooler and the condenser is constructed by arranging one plate pack into the third part, which is divided two functional plate pack parts by an intermediate plate arranged between the heat exchange plates of the plate pack. The first plate pack part functions as oil cooler and the second plate pack part functions as the condenser.

A monitoring method of a cooling system and a monitoring device thereof are provided. The monitoring method includes the steps: establishing an abnormality determination model according to predetermined abnormal data and predetermined abnormal types using deep learning by a monitoring module; generating groups of temperature data respectively by a plurality of temperature sensors; and determining one or more abnormal types and an abnormal prediction of the cooling system according to the groups of temperature data and the plurality of temperature sensors using the abnormality determination model by the monitoring module.

A manifold system including a plurality of manifold blocks form a fluid conduit for fluid flow through the manifold system. The manifold blocks are removably coupled together. The manifold block includes a tubular body defining a first fluid passageway having a first flow axis. The first end includes a first female union defined by a first mounting flange and a neck extending from the first mounting flange in along the first flow axis toward the second end of the tubular body defining an opening to the first fluid passageway of the tubular body at the first end. The second end includes a male union defined by an annular flange and a tubular connector extending from the annular flange along the first flow axis to the second end of the tubular body defining an opening to the first fluid passageway at the second end.

A support structure for a valve module of a refrigeration system includes a support structure that can be supported on the roof or floor of a building by adjustable legs, or can be suspended from the ceiling of a building. The support structure has cross members allowing the components of a valve module to be pre-assembled thereon and transported as a valve control station to an installation location. The pipes of the pre-assembled valve control station can be aligned with pipes laid out at the installation location, thereby allowing off-site fabrication of a valve control station for a refrigeration system.

A new thermal system utilizing removable heat pump modules to decrease servicing time and complexity, increase the range of refrigerants safely usable, increase the efficiency of many thermal systems, and serve new industrial thermal needs. Safe use of potentially toxic and flammable refrigerants is enabled by enclosing the heat pump modules within a hermetic enclosure with multiple overpressure safeties employed. The tool necessary for servicing these thermal systems without any refrigerant leakage is included.

A self-enclosed modular refrigeration unit for refrigeration system comprises compressor adapted to compress a refrigerant. A heat exchanger is connected to a cooling water network to condense the refrigerant with cooling water. A suction line is connected to a suction side of the compressor and adapted to provide a feed of refrigerant to the compressor. A discharge line is connected to a discharge side of the compressor and to the heat exchanger to direct compressed refrigerant to the heat exchanger. A head pressure control valve is in the discharge line downstream of the heat exchanger to control an upstream pressure. A casing encloses the compressor, the heat exchanger, the head pressure control valve. An outlet line has an outlet end downstream of the head pressure control valve adapted to output cooling refrigerant having passed through the head pressure control valve. An inlet end is upstream of the suction line to provide a feed of refrigerant to the compressor.

A solid-state cooling module includes a plurality of housing portions. Each of the housing portions houses a solid refrigerant substance. The solid-state cooling module is configured to heat or cool a heat medium flowing through insides of the plurality of housing portions. At least some of the plurality of housing portions are connected to each other in series with respect to a flow of the heat medium.

Exemplary embodiments provide a refrigeration system having an interior space cooled by a plurality of cooling. Each cooling unit is capable of operating either synchronously when in communication with a control panel or under independent operation. Each cooling unit is modularly and replaceable without the use of tools by means of a quick connect system. The cooling units use a heat exchanger cooled by chilled water and make use of an electronic super heat control and electronic expansion valve to regulate the flow of refrigerant for improved efficiency.

A refrigeration subsystem removably received within a base machine to cool an object. The subsystem includes a body with an opening that receives the object. An evaporator thermally communicates with the object, which is cooled by refrigerant flowing through the evaporator. A compressor receives the refrigerant downstream of the evaporator and increases a refrigerant pressure. A condenser receives the refrigerant downstream of the compressor, which cools the refrigerant. An expansion device receives the refrigerant downstream of the condenser and decreases its pressure, the evaporator being downstream from the expansion device. A refrigerant circuit fluidly couples the evaporator, compressor, condenser, and expansion device such that the refrigerant flows therebetween, all of which are coupled to the body and move together therewith. The refrigerant circuit forms a closed loop that remains unbroken when the body of the refrigerant subsystem is removed from the base machine.
