Abstract: A refrigerator has an icemaker that includes a partition arm extending from the outside of the ice making tray into the ice making tray, the partition arm constituting a part of an ice compartment structure to define ice making cells. When the ice making tray is rotated in a given direction, the ice making tray allows ice to be separated from the ice making cells by being twisted by the partition arm. When the ice making tray is rotated in an opposite direction, the ice making tray allows the ice still present in the ice making cells to fall from the ice making cells by interference with a rotation stopper formed at the partition arm.

Abstract: A device and corresponding method for cooling electronics is disclosed. The device is an all-solid-state optical cryocooler and can include an optically pumped semiconductor laser (OPSL); a cavity configured to receive and control absorption of the optically pumped semiconductor laser, the cavity having a high reflection (HR) surface and an anti-reflection (AR) surface; and a doped crystal housed within the cavity, the doped crystal configured to cool in response to input of the optically pumped semiconductor laser. The method can include supplying an intracavity optically pumped semiconductor lasers to a doped crystal within a cavity; and configuring the cavity to include a high reflection (HR) surface and an anti-reflection (AR) surface, the HR surface and AR surface formed on or in connection with the doped crystal to increase pump light absorption at the crystal within the cavity.
Abstract: Disclosed is a gravity flooded evaporator for use with commercial or industrial heating, air conditioning, and ventilation systems, and which does not require integration or use of a conventional, separately field-piped, surge vessel and associated subsystem.

Abstract: A heat transfer system defines a closed loop that contains a working fluid that is circulated through the closed loop. The heat transfer system includes an electrochemical compressor including one or more electrochemical cells electrically connected to each other through a power supply. Each electrochemical cell includes a gas pervious anode, a gas pervious cathode, and an electrolytic membrane disposed between and in intimate electrical contact with the cathode and the anode. The heat transfer system also includes a tubular system that receives at least one electrochemically-active component of the working fluid from an output of the electrochemical compressor and, if present, other components of the working fluid that bypass the electrochemical compressor. The tubular system has a geometry that enables at least a portion of the received working fluid to be imparted with a gain in kinetic energy as it moves through the tubular system.
Abstract: An evaporator assembly through which a refrigerant is circulated to transfer heat out of a volume of air in a housing in which the evaporator assembly is at least partially disposed. The evaporator assembly includes an evaporator in fluid communication with a compressor for compressing the refrigerant, a solenoid valve subassembly for controlling circulation of the refrigerant, a thermostat electrically connectable to the solenoid valve subassembly via a solenoid control circuit, one or more fans for circulating the air in the housing, and one or more fan motors for rotating the fans. Drive voltage supplied to the fan motors is controlled by a fan controller. The fan controller provides a first predetermined drive voltage to the motor drive when refrigerant is circulatable and a second predetermined drive voltage to the motor drive when refrigerant is non-circulatable.

Abstract: One aspect of this disclosure provides a refrigerant charge compensator having an increased heat transfer surface. The housing has an internal volume and first and second ports for allowing a passage of refrigerant therethrough. The internal volume is partitioned into an indirect refrigerant passageway that extends through the housing and a refrigerant storage area. The refrigerant storage area has a storage access port and is in contact with the indirect refrigerant passageway. Also a heat pump system implementing the compensator is provided and a method of manufacturing the compensator is provided.
Abstract: A solar powered air conditioner comprising of at least one solar panel, an inverter that converts the DC voltage created by the solar panels to AC voltage connected to the solar panel, a battery charger that receives the AC voltage from the inverter and converts the AC voltage to DC voltage, a charge controller connected to the battery charger, a rechargeable battery connected to the charge controller, a contactor connected to the rechargeable battery and to a thermostat, a DC powered motor connected to the contactor, and an air conditioning system, the air conditioning system having an air compressor and an air conditioning motor, the air compressor connects to the DC powered motor via a belt, and the air conditioner motor connects to the contactor.
Abstract: An air conditioning system is provided with mainly an evaporator, a compressor, a condenser and an energy recovery device. The compressor is fluidly connected to the evaporator to compress low-pressure refrigerant exiting the evaporator to high-pressure refrigerant. The condenser is fluidly connected to the compressor to receive the high pressure refrigerant and dissipate heat therefrom. The energy recovery device is configured to extract work from refrigerant flowing therethrough. The energy recovery device includes a movable expander and a valve. The movable expander has an inlet fluidly connected to the condenser to receive high pressure refrigerant exiting the condenser, an outlet fluidly connected to the evaporator to deliver low pressure refrigerant thereto and a chamber fluidly connected between the inlet and the outlet. The valve is configured to control a flow rate of high pressure refrigerant flowing from the inlet to the chamber.
