Abstract: A heat exchange module alone or part of a system including a control console. The HEM can include a channel enclosure assembly, a thermoelectric cooler (TEC) assembly and a heat transfer (cover) assembly. The enclosure assembly includes a channel for a heat-transfer liquid. The module can be constructed to provide for flexibility to better conform and fit on rounded and/or angular body parts and to efficiently transfer heat between the adjacent body part and the heat-transfer liquid via the TECs of the TEC assembly.

Abstract: In an air conditioner, during an operation, a gas-liquid two-phase non-azeotropic mixture refrigerant enters a receiver and accumulates in the receiver in a state where a gas phase and a liquid phase are separated. For example, when the non-azeotropic mixture refrigerant includes two components, i.e., a high-boiling refrigerant and a low-boiling refrigerant, the controller may estimate the ratio (composition ratio) between the low-boiling refrigerant and the high-boiling refrigerant in each of the gas phase and the liquid phase based on the temperature and the pressure of the non-azeotropic mixture refrigerant in the receiver. Thus, the controller may estimate the composition ratio of the liquid-phase non-azeotropic mixture refrigerant flowing out of the receiver as the composition ratio of the non-azeotropic mixture refrigerant circulating in the refrigerant circuit.

Abstract: The present invention relates to an automatic viscosity control system and method for food products dispensed from frozen beverage and soft-serve ice cream equipment. A mixing cylinder includes an auger interconnected with an auger motor. A refrigeration system chills the food product in the mixing cylinder to a predetermined frozen malleable consistency. A motor sensor measures amperage draw or torque of the auger motor resultant from resistance of rotating the auger through the food product. By transitioning between starting or speeding up a compressor when the amperage draw or the torque of the auger motor is below a predetermined high motor performance setting, and slowing or stopping the compressor when the amperage draw or the torque of the auger motor is between a predetermined low motor performance setting and the predetermined high motor performance setting the viscosity of the food product is automatically controlled.

[Solution] A power control system includes: an acquisition section that acquires control unit information related to a limit of an operation by a control unit provided for a heat pump system that regulates temperature and/or humidity; and a control section that controls an operation of the control unit on the basis of the control unit information. The control unit is connected to a power-receiving path of a converting unit that converts received power and supplies the converted power to a load used for the regulating. The control unit is electrically parallel with the converting unit. The control unit controls apparent power in the power-receiving path.

Abstract: An air conditioner is a refrigeration cycle apparatus in which incompatible oil is employed as refrigerating machine oil, and includes a compressor to compress refrigerant, a first heat exchanger to condense the refrigerant output from the compressor, a pressure reducing device to reduce a pressure of the refrigerant output from the first heat exchanger, and a second heat exchanger to evaporate the refrigerant output from the pressure reducing device and output the resultant refrigerant to the compressor. The second heat exchanger includes a heat transfer tube having a groove formed on an inner surface of the heat transfer tube. The groove of the heat transfer tube is formed such that an inner surface area of the heat transfer tube on a downstream side of the heat transfer tube is smaller than an inner surface area on an upstream side of the heat transfer tuber.

Abstract: A refrigeration cycle apparatus comprises a refrigerant circuit, a water circuit, and a control device. The refrigerant circuit includes a compressor, a four-way valve, a heat exchanger, a fan, a diaphragm mechanism, a water heat exchanger, and an accumulator. Based on a value of a low-pressure sensor or a high-pressure sensor and a water temperature on an outlet side of the water heat exchanger, the refrigeration cycle apparatus determines whether or not there is an abnormality due to dirtiness adhered to a plate inside the water heat exchanger.

Abstract: In a refrigeration system comprising a refrigerant circuit, a heat exchanger, an expansion element which, in the active state, cools the entire mass flow of the refrigerant by expansion and thereby produces a main mass flow consisting of liquid refrigerant and an auxiliary mass flow consisting of gaseous refrigerant which enter an intermediate pressure accumulator, at least one normal refrigerating stage which expands a normal refrigerating mass flow in at least one normal refrigerating expansion unit to a low pressure and thereby makes refrigerating capacity available for normal refrigerating purposes, a refrigerant compressor unit which compresses the normal refrigerating mass flow from low pressure to high pressure, and a parallel compressor which, in a parallel compression mode of operation of the refrigerant circuit, sucks in refrigerant from the intermediate pressure accumulator and compresses it to high pressure, it is proposed that, in order to increase the efficiency, the power of the parallel compressor be controlled by a control system, that the control system determine at least one reference variable representing a load state of the refrigerant circuit, that the control system determine a set intermediate pressure value on the basis of the at least one reference variable at least in a parallel compression mode of operation, and that the control system regulate the intermediate pressure in accordance with the set intermediate pressure value at least in the parallel compression mode of operation.

Abstract: An expander-integrated compressor is provided and includes: a motor; a compressor connected to an output shaft of the motor; an expander connected to the output shaft of the motor; a non-contact bearing disposed between the compressor and the expander; a casing; and an extraction line being in communicated with a region between the compressor and the expander in the internal space of the casing and extracts, from the region, the leakage fluid from the compressor side toward the expander side in the casing and to send the leakage fluid to a fluid line connected to the intake side or the discharge side of the compressor outside the casing. The casing seals the region from outside of the casing, thus the flow of the at least a part of the leakage fluid through the extraction line is the only flow of fluid between the region and the outside of the casing.

Abstract: A refrigeration system includes a chiller with an integrated free cooling system and refrigeration system. In certain embodiments, the chiller may be a single package unit with all equipment housed within the same support frame. The chiller may generally include three modes of operation: a first mode that employs free cooling, a second mode that employs free cooling and implements a refrigeration cycle, and a third mode that uses the free cooling system to remove heat from the refrigeration system. A heat exchanger may be shared between the free cooling system and the refrigeration system to transfer heat from the refrigeration system to the free cooling system.
