A novel method of deicing utilizing a fins-on-tubes type evaporator/heat exchanger system that is optimized for energy-saving inductive heating thereof, by configuring it to increase its resistance to a value at which the system's reactance at its working frequency is comparable to its electrical resistance. The system includes a set of tubes configured for flow of cooling material therethrough, and also includes a set of fins positioned and disposed perpendicular to, and along, the tubes, in such a way that at least a portion of the fins comprises longitudinal excisions therein.

Devices, systems, and methods are disclosed for cooling using both air and/or liquid cooling sub circuits. A vapor compression cooling system having both an air and liquid cooling sub circuit designed to service high sensible process heat loads that cannot be solely cooled by either liquid or air is provided.

A cooling apparatus having a compartment for storing products to be cooled and one or more tubes and/or wires connected to the compartment. A connecting element secures the tubes/wires to a compartment wall. The connecting element has a base portion configured to connect to the compartment wall and a supporting portion for supporting the tubes/wires. The supporting portion has first and second arms protruding from the base portion and defining a seat configured to receive the tubes/wires. The supporting portion has at least one elastic traverse member protruding from the first arm and/or the second arm towards the receiving seat. The elastic traverse member is configured to contact the tubes/wires that are inserted into the seat and secure the tubes/wires into the seat.

A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, and a secondary condenser. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a third airflow to the primary condenser. The primary condenser receives the third airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the primary condenser.

A heating, ventilation, and/or air conditioning (HVAC) system, includes a housing configured to direct an air flow through an air flow path of the housing and an evaporator configured to translate between a first position and a second position, such that the evaporator is disposed within the air flow path in the first position and the evaporator is disposed external to the air flow path in the second position.

An HVAC system includes an evaporator, a first sensor coupled to the evaporator at a first position, and a second sensor operably coupled to the evaporator at a second position. The first sensor monitors a first temperature of the refrigerant flowing in the evaporator at the first position, which is adjacent to the evaporator inlet. The second sensor monitors a second temperature of the refrigerant flowing in the evaporator at the second position, which is downstream from the first position. The system includes a controller, which receives a first signal corresponding to the first temperature and a second signal corresponding to the second temperature. The controller determines, based on the received signals, a temperature difference between the second temperature and the first temperature. In response to determining that the temperature difference is greater than a predefined threshold value, the controller determines that a loss of charge has occurred.
