A smart entryway includes an entrance door assembly configured to allow users (e.g., residents) to enter and exit a first space (e.g., a residence) and a storage assembly configured to allow secondary users (e.g., deliverymen) in a second space (e.g., a porch) to store items for later retrieval by the users. A portion of the storage assembly may be optionally refrigerated or heated. A security assembly is provided between the entrance door assembly and the storage assembly. The security assembly includes an authentication device to authenticate users and secondary users and a locking device to unlock the storage assembly and the entrance door assembly upon authentication. The locking device is provided behind the authentication device and concealed from the second space. When a first door of the storage assembly accessible from the first space is opened, a second door of the storage assembly accessible from the second space is locked.

A temperature controlled storage apparatus includes a plurality of lockable storage spaces. Each of the plurality of lockable storage spaces includes one or more compartments. The temperature of each of the one or more compartments is independently controllable to provide any one of a chilled temperature or a frozen temperature. Access to the storage space is remotely programmable.

A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bays. An air seal is formed at the periphery of each opening by resiliently flexible side seals and a top seal to form a highly airtight interface between the pallet assembly and the adjacent airflow opening. When a pressure differential is developed between the chamber and the pallet bay, air is efficiently drawn substantially exclusively through the pallet assemblies with minimal leakage. The flexible sealing arrangement accommodates pallet assemblies with unevenly stacked rows of cases without significant loss of system efficiency.

The present disclosure discloses a refrigeration mechanism and a cold storage warehouse. The refrigeration mechanism includes a compressor, configured to compress a refrigerant, so that the refrigerant flows in a pipeline; a condenser, configured to absorb heat of the refrigerant conveyed by the compressor, so that the gasified refrigerant becomes a liquid; an expansion valve, configured to perform throttling and pressure reduction to the liquid refrigerant; an evaporator, configured to exchange heat with outside air by using the refrigerant to implement refrigeration; and a driving component. The driving component includes an external combustion engine for driving the compressor and a material supply mechanism for providing fuel for the external combustion engine. Therefore, use of the electrical energy is reduced and the cost is reduced.
