摘要： A method is provided for braking a compressor of a refrigeration appliance, of an air conditioning appliance or of a heat pump in which the compressor has a brushless motor with windings and a controller for braking the motor. The controller is configured to brake the brushless motor by using a braking current in a controlled manner starting from an operating rotational speed, in which the braking current during the controlled braking is dependent on induced voltages determined before the controlled braking. The method for braking includes rotating the motor at an operating rotational speed, receiving a signal for decelerating, braking or slowing down, determining voltages induced in the windings and supplying a braking current having a decreasing frequency to the windings, in which the braking current during the braking is dependent on the previously determined induced voltages. A compressor and a refrigeration appliance having the compressor are also provided.

摘要： An air-conditioning apparatus includes a heat exchange unit including a condenser that radiates heat of refrigerant discharged from a compressor, and an evaporator that expands the refrigerant flowing out of the condenser using an expanding device and then absorbs ambient heat into the evaporator, the condenser and the evaporator being connected to each other. According to operation mode, air to be supplied to a vehicle interior selectively exchanges heat with the condenser or the evaporator, or sequentially exchanges heat with the condenser and the evaporator. A subcooler that cools the refrigerant flowing out of the condenser before the refrigerant is expanded by the expanding device is provided. The subcooler is disposed at a position below the evaporator and to which condensed water flows down.

摘要： A method and apparatus to improve the efficiency of a heat exchange system comprising a compressor, condenser, expansion valve, an evaporator and an expansion valve are provided. The apparatus is positioned between the expansion valve and the evaporator and comprises an atomizing disc, an outer connector pipe and two inner pipes inside the connector pipe in contact with the disc. The disc is provided with vertical blades that are angled to provide the turbulence necessary to create a low pressure at the back of the disc. The low pressure thus created vaporizes the partially vaporized incoming refrigerant from the expansion valve and thereby improves the efficiency of the refrigeration system.

摘要： To swiftly start, at the time of power recovery after a power failure, heat source machines, the number of which is equal to the number of machines before the power failure, without including an uninterruptible power supply in an apparatus for controlling the number of machines that is adapted to control the number of heat source machines. There is provided a heat source system, in which a host control device (20) includes a nonvolatile first storage unit (22) that stores the number of heat source machines in operation immediately before the power failure. When power is recovered, control on the number of heat source machines at the time of power recovery is performed in accordance with the number of heat source machines stored in the first storage unit (22).

摘要： The present invention relates to an apparatus and to a method for carrying out a vapour refrigeration process. The apparatus has a motor-operated main compressor which is equipped to suck-in a mass flow of a fluid serving as a refrigerant which is at evaporating pressure level and to compress this mass flow to a high pressure level, and also a high-pressure heat exchanger which is equipped to cool the mass flow of the fluid at a high pressure level, to increase a density and to reduce a temperature of the fluid. Also provided is an expander which is equipped to expand the mass flow of the fluid coming from the high pressure heat exchanger to evaporating pressure level in work-performing manner, and an evaporator which is equipped to absorb heat such that the density of the fluid decreases as it passes through the evaporator and the temperature of the mass flow coming from the expander at evaporating pressure and the temperature of the fluid being fed through the evaporator increase. Finally, there is a sub-cooler which is connected downstream of the high-pressure heat exchanger and upstream of the expander, wherein, downstream of the sub-cooler and upstream of the expander, part of the fluid is divertible from the mass flow and expandable by means of a high-pressure regulating valve to an intermediate pressure level so that the fluid which is then at the intermediate pressure level absorbs heat in a counter-flow arrangement in the sub-cooler and thereby additionally sub-cools the mass flow at high pressure level, and also a high-pressure compressor which is mechanically directly connected to the expander and is equipped to compress, to the high-pressure level, only that part of the fluid that is diverted upstream of the expander and is being fed in counter-flow in the sub-cooler, and to mix this fluid, upstream of the high-pressure heat exchanger, with the mass flow coming from the motor-operated main compressor.

摘要： A system includes a high side heat exchanger, a flash tank, a vessel, a load, and a compressor. The high side heat exchanger removes heat from a refrigerant. The flash tank stores the refrigerant from the high side heat exchanger. The vessel includes a chamber defined by an exterior housing and a tube positioned within the chamber. Heat is removed from the liquid refrigerant circulating through this tube and coming from the flash tank. The load uses the refrigerant from the tube to remove heat from a space proximate the load. The load sends the refrigerant into the chamber between the exterior housing and the tube. The compressor receives the refrigerant from the chamber between the exterior housing and the tube and compresses the refrigerant.

摘要： A transport refrigeration system (TRS) and method of subcooling a heat transfer fluid in a heat transfer circuit of a TRS are disclosed. The TRS includes a heat transfer circuit. The heat transfer circuit includes a compressor, a condenser, an expansion device, and an evaporator. The compressor, the condenser, the expansion device, and the evaporator are in fluid communication such that a heat transfer fluid can flow therethrough. The heat transfer circuit is configured to be in thermal communication with a pressure-regulating device of a system separate from the heat transfer circuit.
