摘要:
A refrigeration system (10) and method are disclosed. The refrigeration system (10) includes a refrigerant source (20), a controller (30) and a heat exchanger (40). The refrigerant source (20) is arranged to receive a feed of refrigerant and is arranged to vent the refrigerant under control of the controller (30) via the heat exchanger (40) and out of the refrigeration system (10).

A heat exchange apparatus (10) is proposed, comprising: - a housing (24) including an inlet, an outlet downstream of the inlet, and a space (34) between the inlet and the outlet; - a heat exchange coil (36) disposed at the space (34) and through which a cryogen flows for evaporation; - at least one wall (42) mounted in the space (34) to separate said space into a pair of chambers (48, 50, 46), each one of said chambers separate and discrete from the other one of said pair; and - a first fan (54) disposed to coact with one of said pair of chambers (48, 50, 46) to provide air flow (60) from the inlet over the heat exchange coil (36) to the outlet. A related method is also provided.
摘要:
A method for managing the operation of a refrigerated truck for transporting heat-sensitive products, of the indirect-injection type, in which the parameter ΔT = Tair inlet - T setpoint (T air inlet : temperature of the air coming into contact with the heat exchanger internal to the truck as a result of the action of the fan, T setpoint : temperature to be set in the chamber inside the truck) is determined in real time and in which if ΔT is greater than an upper setpoint value ΔT setpoint H , a rapid-pressurization (RMP) circuit is activated to vaporize some cryogen and thus increase the pressure in the head of gas above the reserve of cryogen of the truck.

The present invention is directed to a filling system for filling a cooling cartridge (3) in a transport container (2) via a filling terminal (4) with carbon dioxide snow comprising an external supply line (6) for supplying liquid carbon dioxide, an external exhaust line (7) for conducting gaseous carbon dioxide to the environment (32), a filling gun (1) having an internal supply line (16) and an internal exhaust line (17), to which the external supply line (6) and the external exhaust line (7) are coupled and which form a filling end (11) where the internal supply line (16) is surrounded by the internal exhaust line (17), which filling end (11) can be introduced into the filling terminal (4), at least one electromagnet (18) for holding the filling gun (1) in a filling position (P), a filling valve (13) for opening and closing the internal supply line (16), a pressure sensor (12) downstream of the filling valve (13), at least one activation sensor (14) measuring the distance (d) of the filling gun (1) from the filling position (P), a control center (8) for controlling the opening and closing of the filling valve (13) in dependency of the values measured by the pressure sensor (12) and an electric current flow (I) in the electromagnet (18). A filling gun (1) for the filling system contains all measuring and switching devices to safely and reliably operate the filling system and to fill in a reproducible manner exactly required amounts of carbon dioxide snow (dry ice) into a transport container (2).
摘要:
The subject of the invention is the device and method for conditioning of foodstuffs, which solve the technical problems of: maintaining the temperature of foodstuffs at a desired temperature; slowing down the equilibration of foodstuff temperature with the ambient temperature and reducing the consumption of energy products required for foodstuff conditioning. The device according to the invention comprises at least a pallet (1) to which containers for foodstuff conditioning are loaded and containers for foodstuff conditioning (2). Foodstuffs are loaded into containers for foodstuff conditioning (2) in which the temperature is maintained with the flow of the medium at a suitable temperature through the walls of the container. The flow medium for foodstuff conditioning is primarily air; however, any other gas or water may also be used. A fraction of the flow medium may also be supplied into the interior of the containers for foodstuff conditioning to ensure a faster attainment of the desired temperature of foodstuffs. Inlet and outlet lines of the flow medium (5, 6) for foodstuff conditioning are connected to the pallet (1). The pallet is constructed in such a manner that the flow medium for foodstuff conditioning is evenly distributed in the containers for foodstuff conditioning (2). When the container for foodstuff conditioning is loaded on the pallet (1), the weight of the container opens the inlet channel of the flow medium (3) for foodstuff conditiomng by applying pressure on the pallet (1). In the same way, the flow through the outlet channel of the flow medium (4) for foodstuff conditioning is ensured. Several containers for foodstuff conditioning (2) may be loaded on the pallet (1), whereby the inlet and outlet channels of the flow medium (3, 4) are only open in places where the containers for foodstuff conditioning are loaded.
