Abstract: An indoor unit includes: a casing; a heat exchanger through which a flammable refrigerant flows; a fan; a detection sensor detecting a leak of the flammable refrigerant; a warning device emitting a warning about a leak of the flammable refrigerant; a control unit controlling operations of the fan and the warning device; and an operation device inputting stop commands for the fan and the warning device to the control unit based on its manual operation. Upon detection of a leak of the flammable refrigerant by the detection sensor, the control unit starts up the fan on condition that the fan is at a stop, starts up the warning device, disregards a stop command for the fan by the operation device, and permits a stop command for the warning device by the operation device. As a result, a user is enabled to arbitrarily stop a warning started based on occurrence of a refrigerant leak.

Abstract: The portable evaporative cooler for vehicles includes a housing with a hanging hook and suction cups for selective mounting to a side window of a vehicle. The housing is divided into various interior compartments for an airflow manifold, a misting assembly, and a heat exchange system. The airflow manifold includes a fan that positively feeds ambient air through a first heat exchanger to pre-cool the air prior to subjecting the same to a moisture mist from the misting assembly for further cooling. The cooled air flows through a second heat exchanger for final cooling prior to exiting the housing and into the interior of the vehicle. The fan forces airflow in one direction to recycle the ambient air through the housing. A controller is coupled to a temperature sensor and a humidity sensor to monitor the air and control the components to cool the air to desired or predetermined levels.
